5 Tips For Ebike Battery Care & eBike Battery Long Life

[@GreyBeardEBiking]

How often do you charge your eBike batteries and do you charge them to 100% each time?

[@pubcollab]

I have several ebikes (some since 2015 like GB), and generally store them at 40-60%, even if only for a few days (sometimes 80% if I expect too use it soonly). I charge my smaller batteries (400-500Wh) to 100% before most rides, and my larger batteries to 80-90%. I'm not a distance rider, so that's always been enough for me to end up with at least 20% post-ride charge levels (usually more like 30-50%). Then I either use my "smart" chargers to juice back to 80%, or my 1-hour timer to pump 100-150Wh back into the mostly-depleted battery. This has worked well for me - my 2015 iZip still has at least 80% of original capacity, and my most-used bike (a 2018 with Shimano STePS) still shows 99% of its original capacity after nearly 100 full charge cycles.

[@DanBronk]

@@pubcollab Sounds like you are caring for your batteries properly. If you are only using a small percentage of your battery on each ride, then charging to under 100% you will definitely get much more life out of your batteries. 2015 is a great run for an eBike and yours sounds like it has plenty more life left in it. Keep on rolling.

[@obadiahsmith2345]

Hey Dan , I don't want to put an advertisement up but check jag35 for some used good condition batteries.

[@mytrigger5613]

Would you recommend charging with a portable power bank achieved by a solar set up. If so do you have any recommendations? I have the aventon sinch 48v 14ah 500-750w brushless motor and I'm going to start using it for work. I am thinking I'll buy a back up battery and store it under the rear rack. The battery at use is inside the foldable frame. I'm a heavy guy so the 40 miles that the battery claims to last per charge is more like 28 for me. A few hills will cut that range even lower. Thanks Oh, and I'll be charging off the bike and not while charging the power bank whether solar or plugged in through my cars lighter or into the wall. Even if I wanted to simultaneously charge my power bank via solar and charge my e bike at the same time I'm not sure that I could with my current set up, but sounds like something I might look into for maximum efficiency in another build someday.

[@GreyBeardEBiking]

@@mytrigger5613 I have charged with both the Solar panels and from a battery bank. It to forever to fully charge. Like you, I'm a heavy rider so my batteries usually get discharged to 25-30% each time. As far as using the battery bank or the solar to charge all the time. I use both systems occasionally so I can't say from personal experience for long term use. However I have called the manufacturer and they said using a battery bank or solar to charge is OK and shouldn't cause damage to the battery. They even said It may better because of the slow charge. I have two 48 volt 21 amp hour batteries and I and when I ride in the hilly areas with PAS 3 I can get about 30 miles until the battery monitor is in the yellow. That seems to be average for the heavy rides I talk with using the same conditions. Of course, when I see I may not make it home I switch to PAS 2 or 1 and limit the use of the throttle to extend the range. As far as the recommendation, I've had my solar set up for many years and I don't think it's even made anymore. However, since charging with solar is slow I would recommend getting the biggest portable set of solar panels you can get and carry to help with charging time.

[@JasperJanssen]

Mine says I should keep it at roughly 60% ish I=for long term storage - neither fully charged nor fully discharged.

[@mattcameron9349]

I've had my ebike battery for just over 2 years. I do the following 'top 10': 1. only charge up to 90% 2. only discharge to 10% 3. store charged at 50% 4. store in a drawer in the spare-room (12 degrees Celsius) 5. use at least 3 months 6. cycle down to under 3% and charge to 100% once a year 7. only charge from the 50% to 90% the night before a ride 8. only commence charging a minimum of 2 hours after a ride 9. only use the manufacturers 'slow-charge' charger 10. dry-wipe the socket/electrical connections a brush (and contact-cleaner if contaminated) The BMS was 'interrogated' during it's first 1,000 mile service and shows a degradation-rate of around 2% which is absolutely fantastic for a 2 year old battery. I'm a fair-weather cyclist (Scottish Highlands) and use the bike perhaps 2 to 3 times a month. I bought the largest capacity battery available for my bike (460Ah) and am absolutely delighted at the performance!

[@GreyBeardEBiking]

Thanks for the comments and tips. Sounds like your battery care and maintenance is working well for you. Generally, I don't argue with success, but If I was going to recommend anything different, I would say to charge to 100% more often. The older the cells are in the battery, the more they charge at different rates. Some cells may charge to 90% -95% while some only charge to 70% -75% averaging 85%-90%. But like I said, I'm one who doesn't argue with success, so if it's working weel don't change. I've traveled the world but never had the opportunity to visit the Scottish Highlands, but I've heard it's beautiful. I've also heard the area has some pretty steep hills. Does your eBike handle them well?

[@mattcameron9349]

@@GreyBeardEBiking Hi there! I may well change my charging regime to perhaps 1 in every 4 charges being a full charge. Perhaps I'm just being too cautious! As for 'hills', I live just a couple of miles outside the Cairngorm National Park, so it is a bit of a cycling playground here. I'm lucky enough to tie into the Dava Way and West Highland Way (decommissioned railway-line in the 1960's) so it is pretty much the opposite of hilly, nice and flat routes which have been blasted out of rock and viaducts keeping things (for the most part) level. This helps me achieve around 90 miles between charges (Batribike Delta Plus 100nm 250w mid-drive 460Ah, I'm 11st in weight)

[@GreyBeardEBiking]

@@mattcameron9349 WOW! I would have thought your riding area was very hilly. It sounds like you have the perfect eBike and battery set-up for your type of riding. For me I need a little bigger eBike and battery for my very hilly area and my size, about 19 stones (265 lbs). However, I get to ride all year round because we get very little rain and snow only about 30 days out of the year. From what I've heard, it's pretty wet where you are. is that correct?

There are no laws of trespass, jaywalking, etc... so anything goes!) as well as the old 'Beeching Lines' which in Scotland are nearly all converted to cycleways. (Please see the link.

I have read about the "Right to travel or roam" and I really like the concept as long as the travelers are respectful the owner's land. Here in the US, many times a few irresponsible people, a few bad apples as it were, ruin a great thing for others. In the US we have many similar roads and trails as your Beeching Lines.

Do you carry Panniers on your rides to carry your gear?

Thanks for the info on how to properly maintained the battery. My friend advice me in order to extend the life of the battery it needs to extend the charging time of about 1 hour, in your part is he telling the right way for proper maintaining the battery's life?

[@GreyBeardEBiking]

Thanks for the question and the comment. When I charge, I have the charger turn off about 30 minutes after the battery shows 100% charged. With most of the newer and quality batteries, the BMS, (Battery Management System) will keep the battery from being overcharged and possibly being damaged, however, charging for an added hour generally will not increase the life of your battery. But keep in mind, that leaving your battery on the charger continuously after the battery is 100% charger could damage some older batteries with a low grade BMS. Stay safe out there.

Bout a UPP 52V 20AH 40 amp battery 3 years ago and now going on 4th year once 2025 comes. I had been following these tips here 3 years ago of when to recharge, usage in riding, etc. Ive only loss 50 watts as 1800 was the max throttle. However I could of saved half more of 25 watts if I used the PAS system more as I only started using PAS this year due to Cali's new 2025 law of using PAS mode only when over 20.mph. Yes, thank you and thought I shared this to confirm the tips as very practical use for extending battery life. Always check the max wattage when using throttle to set your range mark of understanding how much watts you will lose on a weekly, monthly or yearly basis to check up on.

[@user619tlsdca5]

I've learned this after setting aside my stock battery of shelving it too long as at least once a week to recharge when battery on idle of not using.

Thanks for the tips! Batteries are expensive , so taking care of them makes good sense. I just got an etrike and plan of purchasing a second (20Ah) battery. Mine are Samsung batteries, so they're pretty expensive, but it sounds like it's not a bad idea for extending the life of both batteries. I kind of like the added bonus of getting a much longer range as needed. Thanks again, I had planned to do this, but it's great getting confirmation that my plan should work. So, thanks for that!

Yup for some it will save some dough. For me, I don't worry about the life because, when cared for properly, the battery will last a long long time under normal use. I would rather sacrifice some charge cycles for always being charged up to 100% and ready to ride anywhere at anytime. I think the real keey is how you store your batteries and how you charge them.

[@rebelartstudio3730]

hey there, thanks for very informative video. I was actually trying to figure out about extending ebike ride with another battery or a battery pack. I am first year owner. By accident my ebike was in a storage shed in cold Indiana area during the end of winter. I wrapped the battery in some clothes, but one time left it on bike. I was riding it to work and traveling out of state a lot. I was surprised that the battery roughed out a few cold nights dipping to 10 degrees or so. The battery has been doing very well since. It is June now. I now take it in apartment with me and charge: unplug when done charging every time. First time I heard of not charging to 100 percent that threw me off my bike seat!

[@GreyBeardEBiking]

Thanks for the comment. Yes, you are correct, both extreme cold or heat are not good for eBike batteries. Not only for storage but for charging also. If you are planning for long term storage, like say for the winter, then yes, store the battery with a 60-70% charge and if possible, remove the battery from the eBike for the storage time.

[@victorhuffel4823]

If I may add an extra tip, If you store your battery for more than 4 months, remove the fuse or if there is a seperate switch to completely disconect the BMS, otherwise the BMS or conrtoller will use up some voltage and may deplete to a under voltage situation.

[@GreyBeardEBiking]

Great tip, Thanks. Generally, I recommend checking on your battery charge level every few months so the charge will not be depleted. Do you store your batteries for long periods of time ... such as winter-time?

[@klumze9911]

Good video. I have one additional piece of advice from experience. If you store a battery long term consider fully charging it and riding at least once every other month. Leaving the battery at 70% charge is good but if you dont ride for a year it could drain during that time and you will never get it to charge again. I had that happen to my 1st battery.

[@DanBronk]

Great point. In reality, batteries should be used at least a little once every month or 2. With the cost of a new or even a re-built battery, regular maintenance of the battery can save you a lot of money. When you ride, do you charge to 100% everytime?

[@klumze9911]

@@DanBronk I have been charging to 100% recently because I have been doing range tests on my new bike using each pedal assist level. Once I am finished with each range test i might not charge to full each time. On my old ebike I always charged to full since the battery was small.

I have at least 1 year of experience with each of the following battery "brands": Bosch, Shimano, Yamaha. I also have 1+ years with several "off-brand" (much cheaper) batteries that at least claimed to use Samsung, Panasonic, LG etc cells. In my experience, the "mainstream" branded batteries lost little to no charge when stored idly for months on end, but the inexpensive ones lost large amounts of charge levels. For example, one Yamaha battery (from a Haibike) I had was an "extra" and I stored it at 60% for more than 6 months. Simultaneously, I had a Sondors battery that had about the same starting charge for the same period. The respective charge levels at the end were 59% and roughly 30-40%. I think that ebike batteries' cell quality has as much to do with the need to frequently recharge as anything else.

[@DanBronk]

@@pubcollab Yes, you're so right. I have had the exact same results from the cheaper batteries. You definitely get what you pay for. In my view, a high quality battery pays for it self when compared to the low quality batteries. What kind of bike do you use your batteries on?

An ebike battery when in too hot conditions gets condensation build up inside and with extreme cold it’s ice or frost build up so in both hot and cold environments are 2 types of water produced. Frosty ice or hot condensation. These can cause serious fire risks . So yeah temperatures are definitely important.

What about humidity? We like in SW Florida all year round. Currently we store our bikes and batteries in a utility room off of our home. It has windows and stays a steady temp, but not sure about humidity.

[@GreyBeardEBiking]

Hello Vicky, Not sure if my first reply went through but here it is again. eBike batteries don't like humidity. Out here in California we don't have to deal with that much humidity but I have many eBiker friends who live in Florida. They all pretty much said the same thing. They use a very small fan to continuously blow air over the batteries when they ore on the storage shelf. They said they have never had a problem with humidity. I've also read this is a good solution. In fact, even though we don't have humidity out here in Southern California, there are many benefits to having air circulate over the eBike batteries so I've started using a fan to blow air over my eBike batteries. I purchased a $10.00 little fan from Amazon. Thanks for the question.

[@tconnolly9820]

A very interesting video and I'm a little bit late adding to the comments. I'm in Ireland and I have just got my first e-bike about 2½ months ago. A Cube Kathmandu One with a Bosch 85nm motor and 750 wh battery. I live in a rural area with lots of moderate hills and it's mostly intended as a car alternative commuter and shopper utilitarian bike and I'm averaging about 400 km per month. I'm 2 metres tall or a little over 6'6 and about 120 kg so I'm definitely not aero plus I have racks, bags and baskets for luggage and cargo all over the bike making it even less so. Plus a 7kg chain lock and a large D Lock to secure it to something unmovable and uncuttable if I'm popping into a shop or supermarket. On one of my first 100% charges I got 110 km of mixed assisted riding up to the 25 kmh cut off and then pedalling faster than that myself above the assist cutoff with no uphills or headwinds. But for most of the time I have had to face a lot of strong headwinds over the last two months so I'm mostly getting around 80+ km because I'm using more assist. These autumnal winds really are cycling killers without assist. I have been charging it to 100% most of the time because I'm not going to leave it lying around for more than a couple of days without use and I want to have enough charge to get me to and from work when I'm using it for two days in a row which is a 20 km each way commute. A couple of times I have ended up with between 0-2% arriving home. Other times I've charged it from 30%+ and mostly to 100% unless I haven't got time to complete the charge. I'm sure the Bosch bms is as good as you can get but I still never leave the battery charging unattended without being in the vicinity. And I won't leave it charging while I'm sleeping especially because I work a lot of long night shifts and sleep through the day. I was disappointed to discover that it came with just a 2w charger which takes almost 11 hours to charge from 0 to 100%. I'm considering getting a 4w charger to halve the charging time but then I have also seen other commentators saying that the slow charging is better for the battery life in the long term. I'm hoping for at least 15-20,000 km from the battery before it needs to be replaced or perhaps even better, refurbished and even then just because it's range has dropped by 20-40% at the worst. Time will tell. One of the reasons I went for a Bosch bike is for hopefully being able to get replacement parts or components for 10-15 years into the future like with a car. There are countless e-bikes, both generic cheap bikes and quite a few bigger branded manufacturers that have unique proprietary parts or components that are almost or actually impossible to get even within warranty. And I see that US brand, Juiced Bikes has gone bust. Unless you are an experienced and competent e-bike mechanic yourself, most bike shops don't want to have anything to do with those bikes. You're on your own especially if you buy it online. Shopping around I found that most shops would not guarantee parts availability for even some major global brands for five years. And I have met so many people who have bought e-bikes for €1-2,000 that are literally just high quality recycling after just two years or even less. It's literally the wild west out there as far as e-bikes, parts and components and repairability and longevity comes in and it needs to be controlled, regularised and standardised by legislation in all major markets like North America and Europe but also globally. I ran long and somewhat off topic but in short, very interesting and informative video and it gave me lots to think about. Stay safe out there and keep on pushing one pedal in front of the other. 🚵

Hi Grey, new to your channel very helpful video thanks 👍

[@techspot871]

I hope you can answer my question. On my power outlet i have a Watt monitor that i can watch from my phone. Its a 110~120v 3a charger for my 48v battery. When i first start recharging my battery the power adapter starts drawing full power from my outlet at about 180 watts. when my battery enters near full i see the power draw drop. The watts slowly drop from 180 watt to eventually 0 watts i manually stop it around 60 to 80 watt draw. Im just wondering at what % level my battery starts to charge slower (topping off) and drawing less power from my charge adapter.

[@GreyBeardEBiking]

Thanks for the question. When first charging your battery all the cells are being charge to full, however as the cells get closer to full the charger will "Slow Down" because some of the cells charge faster than others. The Charger doesn't need to send full power to all of the cells because some are already fully charged. Also, letting your batteries charge to 100% every 5th or 6th charge lets the cells balance out. All batteries are different and charging time depends on many things, battery condition, Battery age, ETC.

[@dg9bfc]

when current drops it's near full... 90% or so... a tiny bit below max voltage (depends on pack size and charger size)

It is a definite challenge to learn about, buy, and ride an eBike. But you know, It gets easier after the first ride.

No problems so far either way… Lots more miles & things to see and do.

[@frankcastle5294]

This is a fabulous vid Sir and I just have one quick question if you'd be so kind. I just bought an Aventon Soltera 7 on sale and love the thing. Took it for my 2nd ride early last evening here in southern PA. I can go most everywhere as fast as I want on power level 3 out of 5, and usually ride about 15 miles or so each time. When I get back home from riding, the battery capacity is usually down to about 80% from the near 100% that I start out with. I charge the battery off the bike. Should I charge it back up fully to near 100% after each ride or run it down to near 10% or so capacity left...then give it a full charge to near 100%. Thanks much. Regards, Frank

[@GreyBeardEBiking]

H Frank. Thanks for reaching out. The Aventon Soltera 7 is a nice eBike. If your normal rides are only using 20% battery with no problems, then I would charge to 100% on every other ride. Keep in mind that when your battery gets to 50% charge or less, you will have much less power than when at 100% charge. However. your 350-watt motor doesn't "eat-the-power" like bigger motors do. In my situation, I live in a very hilly area, and I am a heavy rider. My usual rides are 20 - 25% charge left so I try to keep a full charge all the time. Even if I do a "Quickie ride" and use only 10 - 15%, I charge to 100% because I will need the power for my next ride back to home, which is all up hills. I also sometimes carry a second battery so I can have fresh power for that last steep hill climb to home. What kind of riding do you mostly do?

[@frankcastle5294]

@@GreyBeardEBiking Can't thank you enough for responding and happy to hear you approve of the Soltera 7. I was shopping around damn near a year for an e-bike that I really liked, had a good rep, and in my price range. Aventon had them on sale a few weeks ago plus a $80 online discount coupon, free shipping, free rear basket. I'm in Amish Land....southern PA. Looks exactly like southern Germany where the Amish emigrated from. There are a few short, very steep hills that you can ride if you choose or stick to the flats which have no more than an average of 5% grade or so. I blend in 1 or 2 big hills on my typical evening ride but mostly flats. Typically 15 miles or so each ride. I never use the thumb throttle and usually on power assist level 3. Just like you said, the 350W motor doesn't consume much juice. I'll do exactly what you said and charge to 100% every other ride.

I suffer from battery imbalance right now.. battery will go off even when it has 80% charge... I heard charging it over night for 12 hours should fix it, making the battery balance again... Have you tried it? Will it work?

[@GreyBeardEBiking]

Thanks for the question. Battery cell imbalance can cause the issue you are describing, however, there may be other causes as well. I would recommend that you charge your battery to 100% then disconnect the charger. Let the battery rest for a few hours then reconnect the charger and let the charger run for an hour past when it shows full charge. Do not leave your battery unattended while charging. If this does not solve your issue, then you may have other problems. The battery could have been or be damaged, the charger could be defective, the controller on your eBike could be defective, or many other issues. You may need to bring or send your eBike and battery to an eBike battery specialist for evaluation. I don't know how old your eBike and/or battery are, so it could simply be the battery is worn out and a new one is needed.

As of today, 1/22/23, it costs $500 for a second Aventon Pace 500.2 battery. Does it make sense for me to by a second battery through the company or is there some other place I should look? I am a 70-year-old woman who rode just over 1000 miles between April and October. That was year number one. I expect to do about the same but would like the security of being able to insert a second battery in case it was needed. Hmmm.

[@GreyBeardEBiking]

In my opinion, I always prefer to go with the factory supplied batteries. I have 2 batteries from the manufacturer, (Biktrix), and I alternate them on each ride. On longer rides I carry both for the extended mileage. In my 10 years of riding eBikes, I have not had good luck with the cheaper batteries of lesser quality. Personally, I think the quality and reliability of the batteries supplied by the manufacturer are well worth the added cost ... provided the manufacturer is a quality eBike manufacturer. (Aventon is a quality manufacturer). You are putting on some great mileage, a factory battery would be my choice. Where are you putting on the eBike miles.

Hi there! Excellent video filled with great recommendations! In my 2 weeks of ebike ownership, I store my bike in our outside shed, which now reaches freezing every night. But, I bring the batteries inside my house; and I charge them inside, as well. On my couple of rides, I've only discharged the batteries from 5 bars down to 3 bars; so definitely not fully discharging them. But, I also fully charge them after each ride. I'd be curious.....the lithium batteries in my travel trailer (Battleborn 100amp hour batteries) can not be charged when they are below freezing. They also have a BMS system to protect them, but as a precaution, I cut off the solar panel breakers and turn the electrical system off to the trailer when I have it in storage. The batteries are under my bed in the travel trailer; so when we are out camping in the winter (which we try to camp every month, to include through the winter), the battery temps are fine as I can assure you that I'm not going to bring the camper to a location and put up with below freezing temperatures inside. I'd be curious if the BMS on these ebike batteries also has a built in protection to not charge when the battery temp is below freezing. To help protect my ebike batteries, if I do ride in below freezing temps, I definitely will bring the battery inside my house and let its core temperature rise before hooking it up to the charger. I'll probably have to do it similarly when I bring my bikes with on camping trips in the winter. The bikes will be stored outside in the freezing temps. I will bring the batteries inside to charge them in a controlled climate. Have a great week!

[@GreyBeardEBiking]

Hi, I also store my bikes in the unheated garage and sometimes in the unheated shed outside. However, I always bring my batteries inside during the winter for storage and charging. I'm not aware of any eBike batteries that have a BMS that protects against cold weather charging. Since I don't charge in freezing temps, I can't be sure of that. Possibly the charger has a low temp sensor. I don't really worry about that because I pretty much only charge at temps between 60 - 85 degrees (F). Also, I let my batteries rest for an hour or so after a ride before I charge them. In addition, I have the power to the charger on a timer, so the charger shuts off automatically in case I forget to turn off the power. Ride on my brutha.

Thanks for reaching out with your question. Sorry to hear you are having an issue with your eBike battery. The information you supplied is very limited but here are a few ideas. How long was the battery in storage? Years? Was the battery maintained with a minimal charge during storage? If your battery is an older battery and was stored for a long time with no ongoing maintenance, then the battery may have slowly discharged to the point of sustaining damage. All eBike batteries slowly lose their charge over time. I would recommend taking the battery to a certified eBike battery service shop and have them check out your battery. Also, have you checked the charger to make sure it is in good working order? If you have a second battery you can check the charge on a good battery to make sure it is working properly.

Also taking it off the bike means you can control strain on the cord and port. The ports are rugged. But you'd be surprised how a small difference can really increase the resistance or lack of good electrical contact, so it will charge but electricity is weird like that, it might charge but take a long time or you think it's charging but somehow it doesn't fully charge, just due to little breaks in the cable or wires to the pins or the pins get a little loose and don't make full contact. Sometimes the bms kind of acts like it's charging or it is but then later it shuts down because a safety thing. Just some things ive observed with all types of batteries

[@GreyBeardEBiking]

Thanks for the comments. Yes, taking care of your batteries will very much help extend their life. In addition, proper battery care will also be much safer.

Thanks for the 'tips' as I thought I'd take a minute to check a video on charging, before doing so for both mine and my wife's e-bikes! Unlike you, we live in western Canada, where the weather doesn't allow us to ride unhindered in nice weather, so we only ride in dry weather for the most part, so there can be long stretches where we don't ride at all, but we do keep the batteries inside the house, keeping them at a pleasant temperature. Now, unsure of the importance on how to hook the battery, prior to charging...in to plug to the e-bike battery first, then the wall electric socket, or the other way around, or does it matter at all? I always plug to the battery first, but wondered if I was doing it correctly? I currently have 1,350 kilometres on my e-bike, and my wife just a few hundred, but we do take them on vacations as well ride locally on occasion. We've taken up Pickleball, and that tends to take up a good deal of our time, and unfortunately the courts are a good 30 minute drive by car, so we tend to not use our e-bikes for this purpose, but one day I'm feeling like I have additional energy, I just might give it a try! Thanks again.

Thanks for the comment and question. I think I'll soon be experiencing the same type of weather as you. I will be moving to North Idaho this summer. My background is electrical engineering and as such I try to not plug in something with a load on it. The way I charge my batteries is I plug the charger into the wall outlet first then plug the charger into the battery. The I reverse the process when disconnecting. I unplug the charger from the battery then unplug the charge from the wall outlet. With the low charging amps, it probably doesn't really matter but that's just a habit for me on all of my electronics. I haven't tried Pickleball, but it looks like a lot of fun. Where I live, sometimes a 30-minute drive is actually shorter by eBike because of the traffic. What kind of eBikes do you have?

@@GreyBeardEBiking I read that when you plug the charger into the battery after the charger is plugged in, there is a small spark inside the battery charge port, and after a while you create a little weld line inside the port,or carbon left from the spark.....so I've been plugging charger to battery first,and then charger to outlet...

[@GreyBeardEBiking]

@@isawit9722 Thanks for the comment. I use the procedure of plugging in the charger to the power source then plugging the charger into the battery after the charger has been energized because in my experience, the order is easier on the charger. I have not experienced any spark when plugging in the charger to the battery with the charger being energized. However, if you are seeing a spark then I would reverse the order as you described. Thanks again for the comment.

[@isawit9722]

@@GreyBeardEBiking I've never seen a spark.,. I just read a manual on ebikes by a professional electrician and I don't think letting the charger energize first would make much difference.... I also watched a video by same man.....with battery and charger hooked up to meter's to show the flow... when you plug charger into outlet it sparks on the plug, I guess that's what he was going by....

[@GreyBeardEBiking]

@@isawit9722 There are many differing opinions on this subject. And some manufacturers even recommend the 2 differing procedures on how to charge. However, as a retired licensed electrician, licensed electrical contractor, and with over 15 years of eBike experience, the industry standard "Rule of Thumb" is to never add any electrical load to any device, (the charger), before the device has been energized. The sudden load to the device coupled with being energized at the same time, can wear out or damage the device, (the charger). Generally, most of the charger to battery connections should be constructed so as not to allow cross shorting. Also, most of the time "if" there is a spark when connecting the charger to the battery, it usually means the connection points need some sort of Maintenace. Not saying connecting the charger to the battery before energizing the charger is wrong, but from my experience, and from the research I've done, I will keep the charging process as I've been doing it. For me it will be energize the charger then attach the battery to the charger. In addition, I unplug the battery from the charger before I de-energize the charger. I think some of your points are valid and I plan to do some more investigating on this issue. When I find more information, I'll let you know. I hope you will keep me updated also if you find more information on this subject. Thanks for the comment, I enjoy discussions like these. Stay safe out there my friend.

Should I unplug the cord to the battery on my bike between uses or leave it plugged in

[@Simply.C]

After you remove the battery do anything to protect the electrical connection points on the bike with anything? If so, what?

[@GreyBeardEBiking]

I never travel with or leave the battery installed on my ebike when I'm not riding it. Right now, I live in San Diego, Ca. so I don't cover the connections for short trips unless I know I'm going through some bad weather. Also I store my eBike in an enclosed clean and dry garage However, when I'm on a road trip I cover the connections, the motor and the monitor with either plastic bags with bungie cords or for long trips I have a full bike cover. When it comes to weather, I guess I'm spoiled or maybe just a wimp, because I don't ride in bad weather. 😬The full bike cover is the best, but it does present some other issues, such as blocking the vehicle tail lights and license plate. I'm going to be producing a video in the very near future about how to make a simple and cheap taillight and license plate extender. Also, I never leave the eBike on the rack at a motel, I always bring it inside with me. Be advised, some hotels/motels don't allow eBikes or the eBike batteries in the rooms, so you will need check. I know some folks that just don't mention that they have an eBike with them.

[@michaeljohn7467]

If it is going to rain or be real dusty while my battery is off, i use a plastic garbage bag n bungy cord it around where battery hooks into so it dont get wet or dirty

[@GreyBeardEBiking]

@@michaeljohn7467 That's exactly what I do also. If I'm going for a long drive with the eBike on the rack I use a full bike cover, but I will still wrap a plastic bag with bungees around the connections.

[@Jhpc399]

Please help. I am comfuced with the battery's actual 3.6v and nominal voltage 4.2v. On what voltage you calculate your 80 or 90% charge? and how about the theory that the battery is empty at 3v? All the above figures multiply x10 number of cells (36v or 42v or 30v)??

[@GreyBeardEBiking]

Thanks for reaching out with your question. Generally, eBike battery cells a figured at 3.6 volts per cell. I'm not really a fan or believer in charging your eBike battery to only 80% unless you are going to store it for a long time. So, I don't really ever worry about charging to 80%. I charge to 100% on almost every charge. These days, the eBike battery technology has come a long way and the internal BMS, (battery management system) keeps your battery from over-charging. For the best battery health, in my opinion, I recommend charging to 100% on every charge unless you will be storing the battery for a long period of time, like months. And even if storing the battery for a long time you need to give it a partial charge every-so-often to keep the battery maintained. How many times a week are you riding your eBike and how much of the battery charge are you using on each ride?

I’ve got a weaker grip now at 67….so I think I need to get something that has a handle to pick up and move / carry my eBike battery.

[@rhiantaylor3446]

So, if you are only charging to 80% that leaves a gap of 20% x 1008wh to full or about 200wh. Your charger is 48v x 4a or about 200watts, so if you suddenly decide on an unexpected long ride, you would only need about 1hr notice to do a last minute top-up to a 100% charge - give or take a bit. (reality is that the last 20% probably takes longer to squeeze into the battery). Of course, if you are already on the road when you decide to extend the ride that doesn't work. This is just me working out how to handle the charging of an electric car where the value tied up in the battery is rather more :)

[@GreyBeardEBiking]

Thanks for the comment. You are correct. Most people don't realize that the last 20% of the eBike battery takes longer to charge than the first 70%. And as you noted, if you only charge to 80%, you are losing that much power to your motor. This really affects the higher wattage motors. I'm like you, I like to charge to 100% every charge for many reasons, which includes the fact that I never know how long of a ride I'm going on and I want to have the options when I'm out on the road. Are your rides generally of longer distances?

[@justinbogart278]

Any data on exactly how long to wait between charge/discharge and how much cells will degrade if i don't? Battery "rest" time is a pain on ebike tours so I want to know the stakes...

[@GreyBeardEBiking]

Thanks for the question. There is no set time for "letting the battery rest before recharging." There are many factors but mainly it is to let the battery cool down a bit before recharging. As far as a battery or the cells degrading, again that has many factors. How far was the battery discharged, temperature, ETC. My recommendation is to carry 2 batteries on a tour. That way you can alternate the charging. If you must charge quickly after or during the ride, try to let the battery "rest" for at least 15-20 minutes, more if it's hot. Also, "quick chargers" have become very popular, but they do add stress on your battery. I only use the chargers that came with the battery. Bottom line ... if you are on a tour out in the middle of nowhere and you gotta keep going then charge quickly as needed. Doing that "once in a while" will not destroy your battery. If it's hot though, you gotta let it cool down a bit.

[@SonriseSunset]

My ebike maker has larger batteries but not for my model (Polarna M4). Can you add an extra battery that is "wired" in or do they have to be pysically removed and replaced? If you could get a larger battery, do you then need a different controller? And does that controller have to be capmpatible with the display - mine is that green colored LCD display KD986

[@GreyBeardEBiking]

There are many "add-on kits" to wire in a second battery with a switch to switch between batteries. However, I would talk to the Manufacturer to get the specifics for your bike and if it's possible with your eBike and battery set up.

I'm also skeptical of the high current rapid chargers.

[@GreyBeardEBiking]

Thanks for the comment. Yes, I agree with you. I am very skeptical of the current rapid or fast chargers for eBike batteries. Many of the battery fires have been attributed to aftermarket fast charges. With a fast charger, the battery cells often times are not given enough time balance as they charge which can lead to all kinds of battery charging issues and damage to the battery cells themselves. In my opinion, using a fast charger on a long ride once in a while might be OK but for me, I'd just carry a 2nd battery and my regular charger. Yup, I'm with you on that.

My Reention Dorado does not wake up because it sat for 6 months. Can i wake it up by hooking two dorado main powder ports together ?? For a few minutes?

[@GreyBeardEBiking]

Thanks for reaching out. I would not recommend the 2 power ports together. I'm not clear as to the "waking up". Is it the battery or the bike that is not being activated. The first thing I would do is I would check the batteries on another eBike and then I would check different batteries in your eBike. That's how I would begin the process. Let me know what you find out. Thanks.

Hey guys recently got an ebike i noticed the charger can get a little hot so I put a ice pack on it seems to really keep the charger at room temp

Hi. I don't really recommend an ice-pack over your charger to keep your charger cool. I would recommend using a fan blowing cool air over the charger. Make sure your charging area is well ventilated and at room temperature. Thanks.

[@lorenyager8271]

I typically ride one of my e-bikes (fat) in the snow so by the time I get back, the battery is pretty cold. Will the BMS recognize that and slowly charge or should I wait until it warms up to begin charging?

[@GreyBeardEBiking]

Thanks for the great question. You should always let your battery rest and adjust for an hour or so before you begin to charge after any ride. When you have extreme temperatures, hot or cold, you should allow your battery to get to or close to room temperature before you begin to charge. Where do you ride your eBike in the snow?

@@GreyBeardEBiking I bring my battery inside and try to not instantly put it on the charger, my intuition told me that was good, this video confirms it so ill be always doing that now.

Makes sense though XD

[@GreyBeardEBiking]

@@naomi10260 Thanks again for your comment. Most new batteries and chargers have safety features that will keep the battery from being overcharged but, as we know, batteries tend to discharge little by little when not in use for a while, so when the battery loses it charge the BMS system will try to charge it to full. And if this happens over and over it can shorten the life of your battery. This is not common, but it can happen. In addition, I'm a big fan of turning off and unplugging my equipment when not in use to eliminate any possible electrical malfunctions or issues. I'm a retired engineer and some things just stay with you even after you retire. Thanks again.

On a related subject, I have some larger RC car lipos that have been charged 100s of times and and are getting close to 7 years old and they work as good as new. The news only tells us the bad stuff about lithium ion batteries. But the good stuff makes you start to realize the future is already here.

[@papablueshirt]

I did all these tips with my first ebike, I rode about 11,000 miles and I just got my 4th battery. It is a 36v, I suspect it is undersized for the bike. The battery was too hot to touch after riding. I had a wifi plug set up to not start charging until 2 hrs after I came back from my ride. The bike still ate batteries like there was no tomorrow. My new Philodo is 48v, it seems to have a better battery management system as the batteries are barely warm when I get back. I charge to 80% overnight, then have it timed so it will be at 100 percent at the time I go on my ride. I am hoping I will get better mileage out of these batteries.

[@GreyBeardEBiking]

Sounds like you are on the right path for charging. Is you new battery a quality battery from a known manufacturer? Also, what size is the ebike motor and is it a hub or mid-drive?

[@papablueshirt]

@@GreyBeardEBiking It actually has two 1000 watt hub motors. The battery is a 22.5 AH beast. I am hoping it last for a while. The BMS seems to throttle back the power as it runs down so the battery never gets hot. I am hoping that will help the battery last longer.

[@GreyBeardEBiking]

@@papablueshirt Do you also find that your hub motors get hotter as the battery discharges? If the battery issue continues you might want to consider running a separate battery for each motor. Also, you might want to consider switching to a mid-drive motor to be able to use the torque of the lower gears on the drivetrain. When I ran a hub motor I was wearing out the hub motor and the batteries because of the high torque needed for the hub drive. Please keep me updated on how your new battery performs. Thanks.

Hi, thanks for the question. I have the same conditions. I ride pretty much everyday between 18 - 25 miles and I charge to full charge because I don't want to run short of power on my rides. I have been doing this on my 48-volt 21-amp hour battery for over 2 years and have not noticed any reduction in power or range. And really, with 1000 to 1500 charge cycles, that's 4 or 5 years worth of battery life so I don't worry about the charging cycles. I charge to 100% every time so I can enjoy my rides with having any range anxiety. What is your eBike and battery setup?

[@miked9646]

I bought 2 of the REI Co-op e1.1 bikes about a month ago. Today I noticed the battery meter on the battery shows red when the button is pushed. When I plug the charger cord into the battery the charger light stays green. Neither charger will charge the battery. The battery is a 36v 13 Ah, model BT F14 430.0, The other bike battery works fine charging and in the bikes. Any thoughts? It was working 2 days ago. It started to rain and the battery was a bit muddy but it was dried off right away and went into a dry car then the house. I also have to admit that 2 weeks ago I launched it out of my bike bag after hitting some baseball-sized rocks at 20 mph. The battery case has some scratches but did not crack and I have used it about 6 times since then.
