Which is better: 48V or 52V battery?

[@intowishin2755]

For all you complainers out there, the music serves a purpose! It masks the background noise which is far more annoying. The man's gestures also serve a purpose! They make it easier to communicate! Maybe you people should try making an outdoor video with no music and no gestures and see how many complaints you get in the comments

[@speedsterh]

One other advantage I see in using a higher voltage battery (52V or otherwise), is each individual cell will give less current to the motor, which means less voltage sag, which means the BMS will be ON longer before battery cutoff, which means the useful range of the battery is higher as well. When the battery ages and the internal resistance of cells starts becoming a problem, you won't be annoyed as much with higher voltage batteries.

48V is better to buy because they're more commonly available. 52V will get you more power but its not as common so you'll be paying an additional cost based on the economies of scale for the 52V.

[@billybbob18]

Agreed. I bought a bike that uses 48v 14AH and it's a common battery case style found in many different internal battery e-bikes. Paid 325 for a second 48V 14AH battery on amazon. That same case style is also found in 36v setups and still fits my bike. Gotta love standards. 52v is only a few percent higher and not worth it for a non-standard voltage.

[@ronziebell337]

I have broard electrical experience thanks to my trade, but im new to ebikes. I have been researching for afew weeks now in preparation for my own ebike build, and having read many pages on forums and websites, and having watched dozens of videos relevant to diy ebike builds, this is only the second of your videos i have seen. You seem to very intuitively select the topics you address, and then you break them down very cleanly, and present the information in a way that is pretty easy for everyone to understand but simultaneously keeping a good enough pace for people who already have electrical experience. Great videos, im off to trawl through your back catalogue, cheers!

[@pilotavery]

Hello, engineer here! A higher voltage battery does run slightly cooler, but it's negligible. This is because while it does draw the same amps, it gives you more total power, total watts, to the wheel. This means that you accelerate faster and thus don't have to pull that amperage for as long. Of course, if you're climbing up a hill at the max power continuously, then it's going to be equal, but you're just going to be going slightly faster on the 52 volt, but if you're at your top speed and the current draw has dropped below its peak, for any given required wattage to maintain your speed, the amperage will be lower on the higher voltage battery. In reality it really is just negligible, 52/48 - 1 yields the percentage difference... In other words if you are climbing up a hill at constant speed mode somewhere around 70% load or less, and very specific situations, you can see that it draws fewer amps to maintain that speed. But in real world usage the way that most people drive it makes no difference

[@barelyafloatwithsteve3975]

Thank you ‼️ I'm an Older guy with some health limitations, doing my research on ebikes. Your videos have been very helpful and informative. From watching I've determined that I want a Mid Drive, with a Minimum of 750 watts motor. Step through frame, half or full throttle, I'd like to get 24" rims if they have them, with the fat 4" tires. Preferably foldable as I intend to get a boat and bring the bike aboard. Keep up the Great Content, the information definitely helps people of my age. Stay Safe ‼️🙂

[@scmacklin1]

For me personally, the sweet spot is 36v 14Ah. I have the power I need and I can operate at speeds that are not life threatening to myself and pedestrians, while enjoying ~35 miles between charges.

[@Zeppelinlv2007]

Same here! 35miles? What kind of battery setup do you have?

[@danielseifert3309]

Interesting. I have a DYU D3 running on a set up of 10.4ah ion Lith 36v, 250w brush less motor. I've been looking at a high spec battery, but not finding very much as yet. Needs to be same pack size to fit into unit. Unless I attached second external battery and run that through the same system?

[@jimbuell547]

I just bought an Emove Cruiser E-Scooter with a 52v 30ah battery, and 600 W motor. Your youtube video has me interested in learning a lot more about this industry. Thanks.

[@dalehall7139]

Yes, I really wish I had gone with 52 volt instead of 48. At that time I new nothing of lion batteries, very little about ebikes. Now almost a year later and two builds, one a hub drive and the most recent a BBSHD, I realise that I should have not been afraid to go 52. Amazing how much a man can learn in a year, and a lot of what I have learned came from the information you have provided Micah, thanks so much and keep doing what you do!!!

[@ronkoop1933]

This really clear's up all my questions about the difference between the two voltages and the advantage of one over the other

[@geebonzo]

You are well informed and you are an educator, but I worry this industry is 90% marketing. I think people noticed some of these 3AH + cells had to be run to very low voltages to get the amp hours out of the cells. So you ended up with low voltages at the bottom and the 52v was an offset. The difference between 20 amps at around 60 volts, and then down around 40 volts is HUGE. They could use DC-DC converters to maintain the voltage. I think this is a design flaw, or over-reaching on the tech. I have a $250 LiFePo from China, two years old, rated at 36v. It stays above 36v for 75% of the capacity. It stays above 36V drawing 750 watts. It seems to me it is a real battery. Those last two mph of speed are the ones that draw the most amps, at the top of the drag curve. Most factory bikes treat the owner like an imbecile. The idea is to never educate the rider to any aspect of electric power. DIY people tend to chase things that are very hard to design, at least if you want some long term performance. Micah, you are just going to have to hammer away at the basics. People have a long way to go on this stuff. The tech is transformational, but the folks think it is a passive experience. There is a tremendous opportunity, in lithium and solar, for RV's and tiny houses, but it's hard to find the tinkerers.

[@andycapo9you]

George Sears Li-po's can ble flatter in terms of energy releasing, but they still heavy as fuck... 25ah 48v lipo is almost 10kg (3.2v 5ah 142g A Cell!). With Li-ion you can do the same package with a higher voltage and a weight of 5kg only. I have both and li-po can be a good option for a power wall but not foa a normal to light weight bike. I have a trike with the 25ah li-po/crystalyte rear hub and no one can lift the bastard from the ground... For some reason the whole car and bike industry is using Li-on

[@brannenthompson9662]

I have a question for you George when you say your battery is 36v over 75% of your capacity do you mean while drawing around 750w as I have a 36v 15ah bottle battery and even after about 4ah it dips below 36v when drawing about 750 ish watts and today after around 9ah it was showing 31.99 at 750 ish when not drawing any energy it returns to about 35v is my battery buggered its 2 months old and I follow all the charging guidelines 42v etc the battery didn't cut out below 32v either. I 've been using a watt meter for this info you seem to know what you're talking about it seems so would love to hear your advice and any tips. Many many thanks, Brannen.

[@geebonzo]

No, it's probably not any kind of problem. A standard Lithium cell, more than one chemistry, has a pretty steep discharge curve. Early on it is at 4.2 V per cell and then, at the end, it is 3.0 volts per cell. So with a 36v battery, 10 cells, the voltage starts over 40 and drops to 30. The LiFePo4 has a flat discharge curve (so do hobby type batteries, the LiPo). So with a big power draw, the voltage will show maybe 34 volts, and then it goes back to 38 volts with no power. The more you draw the more the voltage will sag. Toward the end of the battery it pays to nurse it along with a few hundred watts, at most. What is worrisome is when you draw 750 watts and the voltage just plunges, which normally will shut down the motor. You want to know how many AH you can draw to get there. It's good to know what the battery is doing and know what is normal. My older cells, like the 2000 mAh, hold voltage better than the newer high capacity, 3000 mAh cells. These little meters are your friends, in the sense that you can judge the capacity over time, and you can rate you battery usage so you don't run out, on the fly. A little information, and a $20 meter, goes a long way. Here's a discharge curve graphic (figure 2). It seems about right for standard lithium, not LiFePo. www.richtek.com/battery-management/en/designing-liion.html

[@brannenthompson9662]

Thank you so so much for getting back thats helped put my mind at rest but I still dont understand why my battery didn't cut out at 31.85v as the BM has an under voltage protection and is it safe to run the motor at full load or should I try to keep it above 32v by feathering the throttle also how do I know my battery has given all it's capacity as it's 15ah and I don't seem to be getting any where near this as at 9ah its dipping below 32v at around 750w load. It just shows there are great people out there willing to share their knmowledge. Thanks

[@brannenthompson9662]

[@devanshgupta2702]

All this stuff is much more cooler then it look like... I'm working on batteries from last 3 years and everytime your video will increment me a little bit. Thankyou for this..... Love your work bro

[@trench47]

Another advantage of 52v over 48v is the depletion voltage of 2.5v per cell gives 35v over 32.5v respectively which means you don't feel as much of a sag in the bikes performance near the end of the charge.

[@someonespotatohmm9513]

voltage will sag more as you lose 1.3v *14cells instead of a drop of 1.3*13 cells. your end voltage is 2.5 higher though.

[@anthonypacis7104]

This is why your batteries don’t last long...... a 3.7v battery will charge to 4.2v. If you only use your battery till it’s about 3.7v per cell, it will last so much longer. Lithium batteries are very tough.. the best way to shorten their longevity is by running it till the voltage is below 3.5, though most people will run them until each cell has 2.5v... running your batteries that low is the reason that most have to replace their batteries within a year and the reason that their batteries doesn’t perform the same after a few weeks of ownership.

[@mick2d2]

My first e-MTB was with a BBS02 48V 20A with a 13s5p battery. I was happy with this set up, but felt that on some occasions I wanted more power and range. When I switched to the BBSHD (48V 32A) last summer I went for a 14s9p battery and it's made a huge difference. It's pretty flat where I live and I use 100-275W of power most the time, boosting on hills, against headwinds or rough, muddy or sandy terrain. Mostly I do around 40-60km a run, on occasion up to 100km. I find that with this battery, I'm always in the "good" part of the battery charge, i.e. above 48V. Also if I do hammer the battery, it seems to bounce back a lot better than the other one. Obviously the strain is now shared over 126 cells instead of 65 on the other battery. With the drop in prices, it only cost me 100€ more too!

[@joshrajcany1019]

[@chrissinclair8705]

After just installing a 52v battery I can say it is definately worth it. It was only 20 bucks more over a 48v from Aliexpress. Best 20 bucks I've ever spent. There is almost no appreciable voltage sag compared to the 48v until you get pretty low. At 48v nominal compared to a 48v battery you are down to 23 percent on a 52v so the vast majority of the battery power is above 48v. Climbs hills faster, faster acceleration, faster speed, can keep a faster speed for longer due to the higher nominal voltage and I can say to my friend "52 volts bitch!!" Also came with a really nice 3amp charger with a fan instead of the grim 2amp shit chargers you normally get with the bike.

Considering that one can charge these batteries to a slightly lower voltage to extend their life, would it be appropriate to get a 52v battery but charger it with a charger meant for 48v batteries?

[@shanereinholdt1526]

Grant ... i am going to weigh in on this and give you a bit of good advice with charging/ discharging these lithium batteries. Firstly do the math with what you doing ... or proposing on doing in respect to the total charging value. 52v battery pack is going to have 14 18650 cells in direct series (well actually the best and longest live zone is to pair 3 18650 in parallel series and theneach group in series. Total 42 cells Sorry anyways the math: 48v / 14 = 3.43v While the nominal voltage is very commonly shown and calculated as 3.65 volts (3.65*14) =51.1volts 4.2volts is peak 58.8volts FYI - Grant the best idea is actually to stop using the battery where your charging stops. And charge it full again to 58.8volts and actaully about halfway discharging is going to increase its longevity and performance. By only charging it to 48volts is actually quite terrible for these types of batteries, and your wrecking it Also fgully discharging ---> full charging is not great either. In both case these practices should be avoided!!! FYI

shadowdance4666 Hey I’m deciding between these two exact bikes. Any recommendations from you or anyone that has some experience with these would be greatly appropriated. Thanks

[@shadowdance4666]

cdriz1 Well, I bought the RadRover. The extra battery is $550 when I bought it. My advice is keep it dry. Mine weirds out when wet. Like shuts down. Can’t speak of juiced. My real thoughts on hindsight are at least for me. Get a bike with a mid drive motor. Don’t get a bike with 4” tires. Around 3” or under is fine. 750 watt motor minimum. Not a 750 watt peak like Rad. I live amongst hills. 48 volt is ok. 52 volt is best. 16 Wh or higher for power or distance. Hydraulic brakes a must. Regenerative braking if you can get it. Adjustable regen is cherry. I would like a full suspension. Spend at least 3K but not over $4,750. That’s the point of diminishing returns. I know more now and wish I saved more but, I was impatient. I had fun and learned though. The RadRover isn’t that great off road. Extremely heavy and I’m not a small guy 190. It’s clumsy if you’re going the cheaper route the RadCity might be a good choice. It has regenerative braking. Mild regen. 1 miles recouped after 20. Or 5% from my research. Adjusting the brakes suck enough on manual brakes. That’s all I got. Good luck 🍀. I mean break a leg

Hi Micah, I am a fan of your videos. I have a question related to this video. I have a 36v battery. Would I see the same benefits described here if I use a 40v battery (11s) instead of a 36v (10s)? Provided that my controller should draw only 36v, would I also experiment a larger capacity/range (everything else equal), given the higher Wh figure? Thank you in advance for your time

[@brannenthompson9662]

Good question I would have thought the speed controller would go nuts thinking its overvolting, sorry I'm still learning, I was going to buy a new controller one of the 36v 48v ones, that have a self-learning wire that tells the controller if you have a 36 or 48v volt battery or just the phase of the motor not 100% sure I need to do more reasearch, thenat a later stage when the warranty runs out to add a 16v battery to my 36v battery to get 52v does the controller shut down? So can anyone help us both?

[@ronl6882]

Great video explaining pros and cons of the two batteries. Can you do one on the different motors - models and size? Thanks

[@fookschool]

When people say you pull less current, they mean at the same speed, not at the higher speed possible. For example, if you cruise at 20mph on a 48v using 480watts, that is 10amps pulled. 20mph on a 52v is still going to take 480 watts which equates to 9.23 amps. 9.23amps @ 52v

Asinine male rivalry

[@karlasch5475]

I think his criticisms is justified, but it could have been expressed in a more polite way! As long as you maintain your speed, or better, your energy usage, more voltage equals to less ampere, which in turn results in less heat ( because current/amperage causes to heat, not voltage. Voltage just causes more current to flow as long as you don't slow down)

[@monstercolorfunco4391]

If you can buy a profesionally built bike, a 72V battery is better for mountains and off road with high amps. it's kinder to the individual batteries, longer battery life, and it's less hot on the motor and the plugs. The official recommended limit for safe DC voltage that doesnt go through skin is 60v, so it's best if home builders stay under that. some garage guys even fry their wedding rings with 12v, so it's best to stay safe.

[@melvinbelcher7606]

Will need a battery book soon. Thanks

[@Hadeshands]

Please do a video on motor watt difference. Ex, is a 500watt motor better than 300watt?

[@treebeard3579]

You don't need a video. Its basic physics. Watts are a measure of electrical power, or 'work'. More work = more power from the electric motor. Naturally, more is better if you can afford it.

[@Metal-Possum]

Given the efficiency of an electric motor, more power is generally a better idea (besides the common weight increase). If you use a 500w motor at 300w, it should be no worse for battery use than a 300w motor, but has the extra headroom if you need to pull more current, etc.

Hey, what do you think of a home made spot welder?, recycled 18650 from tools and laptop batteries?, I have been watching your videos (I know you like to make only the top quality ebikes) but could you do a super low budget ebike build, just for the ones in the crowd that have little to nothing. thank you for everything you have thought me and others.

Thanks for explaining the difference in these two batteries! Now if someone asks me why, or what the difference is, I can tell them with full confidence!

[@leardrum1137]

Thankfully, within 2 years or so lithium ion batteries will finally start becoming a thing of the past. So, what’ll we do when that time comes and we’re given the phenomenal ability to ride for 100-200 miles on a single charge, and then fully recharge in only 5-10 minutes.... I’ll be singing Joy to the World as loud as I can, and RIDING MY ASS OFF!!!

[@marksdaman9408]

Tango Sierra I sure hope you are correct about that! Sounds great to me.👍

[@Jafmanz]

The same guy that Invented the Lithium-Ion battery has invented something better. Still early stages do not expect anything to hit the market for at least 4-5 more years. also China and Korea are both close to something..... or closer... I cannot account for the performance gains. On the other side of things In Britain super capacitors are a real prospect that may well blow everything else out of the water because it simply makes batteries in their current form redundant... imagine it taking a few moments to charge a bike fully and being able to do hundreds of miles at speed, pulling a trailer. and this is not fiction...

[@cartmanrlsusall]

Celtic_Ape. Farfetched but not fictional and lithium batteries were developed from lead acid battery producers.,graphene capacitors are showing potential like you are describing but there are still none on the market,

[@Jafmanz]

Not as far fetched as you might think. My job is to test energy density and lifetime/runtimes I work for a drone company. things are happening. slow and steady.

Mine uses electrical pulses fired into chunks of living muscle that directly manipulate the pedals and the controller is just some gray matter housed in a bone sphere, all internally routed cables. It’s a mEbike

Very helpful. I am building a hybrid bike front ebike wheel (48 volt 1500 watt, with a gas motor driving both back wheel (trike) through a limited slip differential. I recently ordered a 52 volt 30 ah 1500 watt battery,(could not find a 48 volt 1500 watt battery) looks like in retrospect I did just fine, as I was worried about harming my wheel, not so now. Thank you for putting me at ease about my decisions.

[@yycbiker]

Why not have the gas motor run a generator to Charge batteries then you could have unlimited range by filling the gas tank? People have tried using solar cells to recharge battery.

[@Boxbeat666]

52v will fry your controller quicker. too near the 60v max output at full charge.

[@Funcentric]

Current is based more on the motor than either the controller or battery. It's the motor that draws the amps. If it draws more than the controller can handle, that's not good news. Generally when people up size a battery or overvolt, they're going to get more excited and use it more aggressively and are actually more likely to draw more amps out of the motor than previously.

[@shaggy9227]

Clear information and well presented. Right now trying to decide if converting my mountain bike to electric or gas. Car die and live in Hawaii, so rains a lot, but its stupid not to commute to work by bike. Just need the extra power so don't show up to work sweating. Super hot and humid year round. Mahalo

[@lucca783]

So much to take in but I have a little vintage 2 Stroke that I want to convert glad I found you

[@robertsyputa6855]

There are many good comments but I thought providing some guidelines might be helpful. First some caveats: 1) Not all batteries that are listed as xxAH at 24/36/48/52/60V are the same. Batteries vary in the amount and purity of the lithium (Li-ion, Lipo) and internal connections. This determines how much power the battery can store, for how long (low discharge), and the rate the battery cells and total battery can charge and discharge. Cheap batteries tend to cheat on some or all of these factors. It costs more to use more of the lithium, silver or other precious metals. And it requires a working environment that keeps the materials uncontaminated, 2) If you want to get high power out of a battery pack by using high current limits, that can impact the life of the battery. A battery pack that uses high-current (High C rated) battery cells and is properly built will, as a rule, last longer than a battery that uses cells with lower current ratings. 3) Setting high current limits on the eBike display can exceed the limits on some batteries or the motor controller. That may result in a performance increase but also in the need to replace the battery or controller. 4) Increasing the voltage at the same current limits results in a higher power level (P = V x I). Several posts have asked if increasing the voltage from xxV on a XXXW motor is OK. That depends on the maximum voltage and power ratings of your motor, controller, and wiring. The wiring is not usually a concern but as the power is increased, borderline connections or gauge of wires can become a problem. My thinking about upping a 48V ebike to 52V is that this is more of a benefit in providing a more even power budget as was shown in the video. That changes the objective from trying to get more high-end power out of the bike to wanting to get a good level of power over a longer ride distance and up and down more hills. A 750-1,000W motor can get most fat arses up hills. I like eBikes as a way to cover more ground and make biking more of an adventure. There is plenty of power to help up steep trails.. to the point that I have to walk/carry the bike due to not being able to get traction. Fellow weenies, I am 68 and do not want more power than 1,000W. But I want that power to last longer before voltage drop degrades performance. And I want the kit to last for longer trips and for longer life before needing to replace stuff.

[@franciscomanzo8747]

That's a really good information because sometimes we think that more Volts will hurt our engine of 48 V. I hope to win your book😊

[@JFSVideos]

I actually followed all of that, well done. I was going to add you get a bit more range (at the same speed), but you slipped that in right at the last moment.
