Hi I want to know what the largest battery capacity ever put on a electric bicycle is. I want to hear from other on what they have found and seen. No trailers with extra batteries, no switching in new batteries & i dont use any charging with solar panels. Basically the most battery capacity on a ebike off a single battery charge.
I am building a electric mid drive yuba bike and plan to have over 7kw of battery to make the longest range ebike possible. I have purchased a 103.6v 68ah nominal Panasonic cells battery specificly made for yuba bike in mind, which is lightweight at 56 pounds. And I plan to tune for max efficiency. I am not just claiming 333 miles and more at average speeds, but i plan to prove it guineas world record style hopefully. What do you know?
Range chart provided based on wh/mile, with battery % pulled from pack, speeds to be assigned later.
 
Deathbike is 102V nominal, 56Ah ~5.7kWh.

Luke it so amazing to catch you seeing my post. I think im going to faint. You are like a super star to me for ebike revolution. I will catch you later with a couple questions. Thanks for poping in. Wow that's some serious battery. Is it 5.7kwh you are restricting your self to? Should be higher than that at that voltage and amp hour. Also later hope my bike can push 65 mph with set up briefly for an occasion. Opps messed up on math, thanks understood at 5.7 kWh, Sorry changed the title at last minute of this post to longest range on ebike battery.
 
Im changing title back toThe most battery capacity ebike you know of? Sounds better for my purposes.
So please let me know if thier is a higher battery capacity out thier on a ebike, than 5.7 kwh.
My yuba ebike battery is 7kwh= 7,044wh.

Kw has little to do with what the voltage and Ah is, on it's own (depends on C-rate of battery).

Kwh, however, is directly derived from voltage and Ah, and is what pack capacity is measured in. (either using nominal voltage, which is more realistic, or peak voltage, which is not really useful except for marketing lies).
 
Yes, it's a lot of weight for any bike. My most recent creation can carry quite a bit of battery by filling it's panniers, but it's main battery trays are designed to hold 2KWH of 18650 cells, which is not such an unreasonable load out.

Right now I have a 48v 20 ah and a 48v 13 ah that go in the trays, the bags by the seat. ( 26ah actual, the 20 ah pack is shit) And I just got some new RC packs for another 20. So If I load it all on, I have a realistic 100 miles of range riding about 20 mph.Finished cargo mixte..jpg

This is a lot of battery, even if only slightly over 2kwh. I need 70 mile range to get from town to town out west, and my ass is screaming for mercy after 5-6 hours of riding. So far, my personal best day was 80 miles, and I find a 50-60 mile ride a nice day out.

So what I'm wondering is, what do you need that kind of range for? Are you going to ride fast enough to use it all in one day? That's going to be a very uncomfortable ride if so. What for? For me, it's all about the ride, much over 30 mph on a bicycle tire is just damn uncomfortable. I've run through plenty of tires, and understand how much more often you blow out when you ride 30 mph through the road debris.

I'd get it better why you need such a big battery if you were building a motorcycle, something like the death bike, or the Docs drag race bike.

FWIW, given the size of battery boxes you will be carrying, I seriously doubt you will really see 19 wh per mile. But I would find hitting 25 wh/mi very plausible. That's what I was getting with a lot of drag on my big franken bike, at 15 mph. The bike in the pic above gets about 21 wh/mi at 20 mph.

I'm not sure what speeds you are thinking of for your record run, but you aren't going to cruise 25 mph and get 19 wh/mi. So it's going to be a long day if you plan on 300+ miles. 15 hours in the saddle at 20 mph, not counting breaks.
 
If you're looking to break a record and the 18650 cells you'll be using are 4.35V capable, I wouldn't charge them to 4.2V...

The reason I need so much battery is 1.) To set the world guineas record at bicycling speeds of 15mph is at least average bicycle speed, 2.) For my everday job, plus I like to travel, and don't have to worry about charging as much, 3.) Also I will have more range after battery degrades many years later, 4.) Show others the best in the electric vehicle revolution & battery tech & help ditch some ICE's. Also I like to show off a little. Here is a pic of my old ride before getting hit by a truck, the driver was not looking and broke the old bike and injuried me in the process. My guineas attempt will be while switching riders back and forth for the range record due to fatigue.

By the way if someone has more than my 7kwh of battery on a ebike, I want to know as much details. Or just share your most battery capacity put on a ebike, I find it facinating. My battery is being made all thanks to Shawn McCarthy and green axle llc, & batteryblocs.com. my pursuit for 200 mile range ebike turned out to be more closer to 300+ miles range when I was buying my battery.
 
That's a whole lot of batteries. Wow. The large pack I built comes in at only 3.5 kWh . 252 tesla cells. It all fits in the triangle though which was the big challenge. Longest ride so far was 98.5 miles with 25% battery remaining. I don't ride super far very often. Probably average around fifty miles or so between charging it back up. You have an enormous pack there. Hope you have a comfy seat. [SMILING FACE WITH OPEN MOUTH]

Yeah that's the same capacity my battery guy had on his yuba, so I have double crazy range. In fact he said one day his 3.5kwh could go about 200 miles at his slow pace. I could even go 400 miles if all conditions are right and very slow. Here is a sample pic of battery case, I will have two on each side clamped down. I will have I believe 560 cells. Most compact lithium battery brand with Panasonic 2c rated cells, so about 136 amps power max constant.

As for long rides, I am going with cloud 9 cruiser seat, and my cargo box I made will have a comfy boat seat back rest. Also I feel bad that many battery builds are soldiered all together, mine is just put together with battery blocs, just like Lego's. & fast and easy to replace a bad cell.
 
Very nice. That's cool you can replace batteries easily. Going to be quite a ride.

Range records on an Ebike mean nothing !
You could go over 500 miles on less than 1kWhr !
..it all depends on how much you care to pedal.
I'm not getting into any range debates, that why I like to focus on battery capacity instead, & range as a side note. But to be technical, my guineas world record attempt should be at (15mph cruise controll) with as much peddling assistance as possible, which defines a electric bicycle better. Of coarse peddle effort will dwendel after so many hours of riding durring attempt. Thought to mention that & seems fair. I just don't know exactly what watt hours per mile will be achieved on average.
 
My apologies Streak, I just gut reacted yesterday. We do get a lot of guys here, who might have done a 30 mile ride once or twice, who suddenly decide "I'm going on a tour, and I'm going to ride 200 miles a day."

This is tougher than most realize. Take Troy Rank (Grinds), His tour was exceptional, hitting very high miles per day. Very young, and very tough to do what he did. The rest of us mere mortals limit out about where the pro race riders limit out, 5-6 hours a day in the saddle. There is just no way we can Equal Troys daily mileage.

Now I get it, you don't plan to carry all that battery every day, It's for a specific record beating ride. That's much different from packing that much daily. But I can sure see carrying 2kwh all the time. That's not near so much weight. You mentioned lego blocks. I'm assuming you don't mean blocks of 40 p or something. I'd go with 10 p chunks for the ability to carry a smaller battery most of the time.

I'm standing with an expectation of 25 wh/mi. I just think you will have enough drag from battery boxes that big, and enough weight, to be in that ballpark. It will depend some on weather, a day with no wind at all could result in better than 25, as could a route with nearly no hills at all. Where I am, a 300 mile ride would take you over at least a few mountains.
 
40Ah of 12s on mine. I could fit another 20Ah or more if I had to. I've done 60 miles on a charge at 25mph average with it, and still had fair amount of "gas" in the tank yet. 120ish lbs.

Still haven 't finished it completely. Honestly I ride it too often to give it time off. 13,000 miles or so on it now. In less than 2 years. 2 years in April I had it road worthy.

In fact yes I plan to leave all 7kw of battery on for looks & to show others what a ebike with a bunch of range does look like. But you have to break it down & the cost for people who want less than 50miles on a ebike & not willing to pay
that much battery. Yes inside thier are blocs made for of up to 10p. I just don't hot rod enough to worry so much about weight. I got bunch of wheels to destroy if needed, mags are good in a since but 10mm axles bend so easy. Hate my towns bad streets & pot holes.

The largest battery I ever made for an ebike was 48V 160AH. It was amazing. We got 238 miles on a single charge.
Darn that's a bunch of battery capacity, I got see a pic of that lester please, including every one else, did it purposely go all on the bike frame?

I love the style of that ride. I to use maxxis hookworm tires inflated to 70 to 72psi for even less rolling resistance to help increase milage. One thing that I didn't establish was find a business that could make a custom fairing to mount on the basket sound like a neat idea for less wind resistance and a high top speed test run.
 
Yeah if I wanted to spend extra I could also add a high powered cycles battery pack in the center triangle, then it be to much battery and absolutely need a good front shock, etc. Not goin to wast my time. Any body else have more than 5kwh battery ebikes? I love details, like c rate and amp making a certain power. I was limited to 2c cells because I didn't want to spend any more on battery, I could of went with 5c or even 10c rate power!, but I think I got a great deal. Some cool bikes here.
 
Well, to each his own. But I'd never want to carry 300 mile range, when your typical ride might be 50. I can definitely see carrying 3kwh all the time though.
 
This summer i will have 13S/40Ah lipo-pack on my velomobile. It is pretty much as much wiring as i can take. Charging is a hassle.
My velo cruises around 150km with it. Consumption on a cruise is around 14wh/km, which is roughly 20wh per mile. Steady 30-35 km/h average.
Big pack kicks more ass. Voltage does not drop much when on WOT. With 10Ah pack voltage drops quite a bit.
