How to add a 2ND BATTERY to your electric bike (Safely)

[@Area13ebikes]

Do you want a custom mount or a case to put the dual battery connector on your bike?

[@pascalkargut3237]

That’s a lot of money

[@jonspeak2807]

Case? Have a poly wrapped 52v 20ah auxiliary battery for my Scorpion.

[@davidcoulson8346]

Yes , what about a Sondors step ?

[@vincentvincent2658]

reccomend you buid stuff specificaly for radrunner plus or radrunner because these popular branded bikes will be the the people buying your kits and upgrades

[@zechariahkress3741]

I would like a case. I have blacked out my Runner and the shiny aluminum would not look right, but if I paint it black it would affect the heat dissipation. Actually that gives me an idea to mount above the 35a controller that sits at bottom of frame…

[@M.Mae.M]

Love how you are helping people with upgrades but at the same time carving out a business for yourself

[@misterg609]

I love how - in the Wild, Wild West world of e-bike manufacturing - where everyone is using different designs and equipment, you are creating standardized equipment to improve the usability and performance of these bikes! I think you are way ahead of the curve on this, and I really appreciate it! Keep up the good work, Bolton Ebikes!!

[@thomasjue1539]

I was watching this again after 2 years to get a "refresher". Excellent course by the "Professor" - Kyle Chittock.

[@sweendawg7274]

I purchased one and installed it on a wallke x3. It works great! The batteries level out at about 75%, and hover around that range for miles. Thanks area13!

[@tinkernoni]

Do you have a link for the connector?

[@moliver45acp]

Very interesting and technical information about E-bikes and answering common questions that most new owners would ask especially about taking care of your battery and most other components on your E-bike ! I believe that your videos and instructional commentary are very valuable to me and a lot of new E-bike owners everywhere ! I really enjoy your content .

[@bklynkid78]

Thanks!

[@youngjay914tv9]

I believe You are The Man I Was Looking For 😂 I have an X-Class 52v 18A and 52v 20A Dual Battery , Single 1000W Bafang Motor, 33A Controller and added a 40A Battery Blender which fried My controller. Was the Battery Blender 40A Too High??

This video is 2 years old and I didn't realize that there was this thing ,thanks for the video I'm a little late!

[@mike-ology22]

Hiya mate, this video was shared by another youtube Luke Lorusso and I'm impressed. It all makes complete sense to me on how you explained it, and also with the connectors you have thought of every eventuality which is cool too. Thanks for sharing

[@hiramabiff5557]

I LOVE THE MUSIC CHANGE IN THE BACKGROUND

[@brianmchale6668]

That's just the explanation I needed. Thanks I'll place an order. It will be plug and play for me.

[@neemyn407]

I've seen some delivery riders with a battery cradle on the top tube with a full battery in it and the battery that's running the motor is on a battery cradle on the lower frame tube. They would have a switch to change the battery in use if those 2 craddles are actually connect to the motor, or simply physically exchange battery cradles when the lower tube battery runs out of juice for the full battery that's on the top tube. For people that work longer hours or live far from where they could use only one battery, that's a way to extend range.

[@thomasjue1539]

I would like a 2nd battery that can be carried from the rear mounts with a wiring harness kit that is will allow me to simply plug it into my existing wires. That is, I won't need to do any splicing, adding connectors or doing any soldering.

[@SilentHProductionsLLC]

You mean plug-n-play? If you have a Rad, you are in luck. Bolton not good for you, than DateX2 is what you need.

[@danimayb]

@@SilentHProductionsLLC DateX is an excellent device! Super compact and takes care of everything. Comes in different flavours for your needs, The most expensive one will run 3 batteries, Of any AH or Voltage, And can charge all 3 with one charger while on the bike. The cheapest will run 2 batteries of any AH or voltage but no double charge function.

[@ChrisBFerguson]

I just upgraded my membership and sent you an email. My converted e-bike took a turn for the worse today when I was out riding in the rain. The bike is still good but the conversion kit and the battery aren't. I don't have the money for a new one right now but should in a few months. I will be getting my next one from you because I have been very impressed with what I've seen in your videos and live streams.

[@PilAdam]

06:10 is very important, thank you so much!

[@jakereal3604]

I have a 36volt Ebike and did something similar but WAY easier and cheaper. Stock battery is a 13 AH Hailong type frame mount. I added a bike rack and mounted a 36 v 20AH battery on that. I opened up my controller box and there was enough room to mount an ON OFF ON toggle switch. I found a 30amp one with insulated boot over the metal toggle. I then connected the controller ground to BOTH batteries, the controller positive to the center terminal and the pos from each battery to the other 2 terminals. This is mounted under and slightly behind my seat post. All I have to do when one battery runs out is put my hand below seat, switch to the other battery, turn back on the bike and continue riding. I don’t have to Stop, swap batteries, worry about an electronic part failing etc. only thing that can fail is the toggle switch. So I keep a Phillips screw driver in my rack bag. Should the switch fail I could simply unscrew either battery terminal and screw it onto the controller post and close it all back up to get me home. Only down side is at some point to use the total amount of power of both batteries I have to throw a switch. The system here will automatically “link” both batteries so that you can use the total amount of Amp hours without doing anything or rebooting your bike. Both ways are safe and work. I cringe when I hear people doing what I did BUT simply wiring the two batteries in parallel!!! Big no no for reasons stated by this gentleman !!

[@danimayb]

Great, But a parallel connector is still the best and easiest way. It will drain your batteries together alleviating stress on both, Which equals less voltage sag and kinder on your battery cells.. Also you can eek more capacity all together by running parallel to using your batteries separately.

[@MeMe-ng7lp]

[@jbwjr54]

Love the videos. But when instructing, the background music is too much. I know it’s for production value and it has its place, but not when you are teaching something. Is it just me, or does anyone else think the same? Just my thoughts. Thanks for the great vids!😁

[@Area13ebikes]

Thanks for the tip

I didn't really notice the background music here but if there had been music during my physics class, it would have driven me crazy. Good point...

[@kimhyunwoo8983]

I don’t know I’m someone who has ADHD that generally doesn’t impact my normal life but for long drawn out activities without something to drown out my internal brain it’s difficult to concentrate, so music, city scape noise, water droplets… etc actually help me focus better otherwise I’m thinking of too many things at once.

[@Pudnite]

I didn’t have a problem with the music at all, guess my brain is just better than yours

[@hotlineztribe9096]

Yeah, interlude/super cut music is cool but hearing your knowledge clearly is cooler!

[@travissierra8519]

So my suggestion for that adapter in a nylon Cordova weatherproof bag with velcro straps to go around to see it downtube. Or you could put it basically anywhere else . Basically if you have two batteries on the E bike, you could have one as a reserve kind of like they used to put a reserve gasoline tank on automobiles in the olden days.

[@alkraus8818]

Bought two of these and they are arriving today...ON TIME; thanks! Say what you will do, and do what you say - A+ for customer service. QUESTION - Right now we are just changing from A to B battery by unplugging A and plugging in B; works fine. We are going to test your DBPC this on a 200 Miles three day bike ride this weekend on our Juiced RipCurrent S Fat Bikes. Rumors on another DBPC (purchased from another company in March and never arrived - slow/no boat from China issues - F for Customer Service) states better efficiency. We have two nearly identical batteries (Juiced 52v 19.4 AH "A" and Joyisi 52v 20 AH "B" on rack and we normally get 50 miles of range off each battery @ non-ludicrous speed (sub-20MPH Level 1 Assist). Should we expect 50+50=100 range or do you think with the dual battery draw working each battery at 50% we will achieve better efficiency and get "more" range? Also, the aftermarket Joyisi Battery has a front plastic housing that is empty under the cover where I planned to install the DBPC inside. It will look cleaner (I have OCD), but do I need to worry about reduced airflow over the DBPC heatsink housing??? Option 2 is always bolt under the rack for added airflow. Suggestions???

[@eng758]

I have a zoos 1100 bike do u have a battery for it? What do I need to add a 2nd battery and do you have any suggestions?

[@FirstLast-ml7yf]

Is there an ideal diode or Schottkey diode in there to ensure pack isolation? Otherwise dubious..I run two packs in parallel via a "2 for 1" diode (Schottkey) and I never worry about differing pack voltages..I charge both at the same time with 2 chargers, when they are connected via the diode, no matter what charge state they are at relative to each other. Downside is a small overall voltage drop, and impossible to use regen with this setup. I have 23,000 miles on my trike with this setup and great for peace of mind.

Most of these type of device can use batteries with different voltages, 52 and 48 for example. It will use the 52 until it drops to 48, then both are used. Is your info correct regarding this?

[@nicholasmorrill4711]

My first battery an inbuilt one to the frame started to play up so I bought another & have been running the two connected together.When the inbuilt one drops below about 39.5 volts it cuts out so I turn on the new one that has a switch.......so far with no explosions.The odd thing is that it then seems to add charge to the inbuilt one bringing it back into the circuit.

Had to ask so when charging can you? I have a Aventon level wanted to get a triangle battery connect everything up correctly, with that said say I get everything in can I just plug in my battery while in bike and it will charge the other battery?

Also interested in learning how this can be applied to aventon bikes.

[@tracksuitcollector]

How would I go about charging when using this parallel connector? If I pick one battery to charge will it also charge the 2nd battery now if I don't remove the parallel connector? Or should I charge both batteries at the same time with their own separate chargers?

Great video. Thank you!! Gotta move first but sometime this fall, I want to add a second battery to my eBike (Polarna M4). It has a 14ah stock battery 750 watt peak 1000 watts, motor? I question that bc the highest wattage draw I've seen is 932 watts. Anyway, I get 30-36 miles on a single charge but the last 4 - 5 miles, the stock battery just doesn''t have the same "kick", in fact it's downright weak. I was going to get a bigger main battery - like 16- 18ah, but think I'd still have the same issue, just a few miles further down the road. A second battery makes the best sense. I like your new wiring set up. I'd just zip tie it to a conveniant, hopefully semi hidden area of the frame or rear rack (where I will mount the second battery). OIf you come up with a mounting strategy. Maybe one of those adjustable rubber bandings that bike lights use? That would be or could be, attached to the alum housing?

[@Altema22]

Cool device, just wish it handled more current. I run dual Tesla batteries in parallel (39.2ah total), but you have to be careful to match the voltages. Sometimes I just leave them connected and use one charger, and the second battery gets charged with the first one. For those that are concerned, the Tesla batteries have a common connector for charge and discharge, so it doesn't make a difference to the BMS which lines the power comes in. Charging takes longer this way, but I don't have to keep using the power meter!
