The battery on my e-bike quit working and would keep shutting down the BMS of the battery causing the bike to have no power.
In this video I show how 2 of my e-bikes quit working and I show some of the symptoms of a bad E-bike battery.

We have Lectric ebikes from 2020 a version one and a version 2. Each of them has close to maybe 5,000 mi on them and we've been using the original battery and then some extra batteries that we've got. It has taken me some time to realize how important it is to charge these things deliberately, taking time to measure how close they are to fully charged and as soon as they're fully charged unplugging them. And then when it comes to winter making sure that they're down to 50% or so for storage. I didn't become careful about batteries until our very first battery got super hot one evening and after cooling it down with some ice bags realized I really needed to take more time and care charging each battery. Your bag experiment would be helpful to learn from. But I trust that you will be cautious if you do try it and do it in a safe way. Thanks for all your videos especially the ones on Lectric ebikes, they've been great to watch and made me a better bike mechanic.

My Vivi did the exact same thing except when I take it off after shutting off it does not produce no power at all until I plug it into the charger

bad cell.take battery out of case, test each cell.if you find bad cell ,replace it. this should be done by a professional or competent person due to volatility of battery.the awakwardness created by this problem is getting the repair done with reasonable cost, if not under warrenty its almost cost effective to buy a new battery which is absurd.around here nobody wants to work on ebike batteries due to firehazzard aspect.

Three things come to mind, one or more bad cells or overdischarge perfection is kicking on and third is a bad bms.

I'm having the same problem with my Effbike and have just exhaled at having my problem diagnosed. Battery is 4 years old with 3,600km on it, compared to other commentators, I seem to have done pretty well. I'll order a new one in the morning.

KBO offers two year warranty, if I remember correctly. After a year and half Breeze very reliable, no battery issues.

What is the purpose of storing them at 50%+/- vs. a full charge? Thanks.

@JeremiahMcintosh 6 ай бұрын

Lithium batteries do not like being stored at 100% and are more dangerous when sitting like that. They are typically the happiest when stored at their nominal state of charge because there will be less degradation over time.

@terrynelson2385 6 ай бұрын

I think you let the battery charge longer than normal, or did you? I wonder if letting it charge around 12 hours or so would help.

@marshal7102 Ай бұрын

The charger should stop automatically when the battery is full, I have the same problem with one of my sooters.

I had a similar (but different) problem on my Pedego bike. In PAS 5 the bike recently has started cutting off the pedal assist but the controls, display and everything stay on, thank goodness! To resolve I have to switch down to PAS 4 and then it clicks back on. This has happened three times. All three times I was going uphill and definitely not riding at over 20mph so it was definitely NOT a speed limiter overriding and turning off the pedal assist. I had it looked at in the Pedego shop but the guy could not replicate the problem. Haven't had the opportunity to ride since I got it back, so I don't know when / if this will happen again. I have about 600 miles on my bike (bought new) and have owned it for less than a year. If it's the battery I definitely want to know because they will need to send me a new one!

@JeremiahMcintosh 6 ай бұрын

Hmm thank you for explaining your problem. Yeah that is weird and not sure if it would be your battery or not since it’s not shutting all the way down. Keep us updated if you figure out what it is.

@DrBerdi 6 ай бұрын

I'm no expert but that sounds more like a thermal or power draw protection kicking in cutting off the motor to save it. Bad controller??

@huss2854 Ай бұрын

If your bike is in the de-restricted mode, this will make the motor work twice as much, try putting it back into restricted mode .... Reset all the settings in the display.... Hopefully you should be ok

@ltaylorpgh4219 28 күн бұрын

Did you figure this out

@stevehotblood Ай бұрын

When I get on my bike it shuts off right after I throttle it even with pedal assist so it may be the battery

Had same issue with Heybike Mars the battery it shipped with. Battery was just over 1 year old by a few days . After videos and bouncing emails back and forth with China they sold me one at 1/2 price. I use it on the wife's bike she weighs less and it can go around 17 to 20 miles before it kicks out. I have good spares. I blame myself it was depleted a couple times when we were caught out late in the winter and the temp dropped 20 degrees on the way back. Had to peddle back the last few miles in the snow. Freeport to Butler trail for Pittsburgh locals.

@JeremiahMcintosh 6 ай бұрын

Thanks for sharing. Maybe Ill check out that trail in the spring.

Me also exprienced the same issues. I took out the 4 batteries and tested them. All 3 reading 12.++ volt which is fully charged but the 4th only reads 6.++ volts. Eventhough the motor specs says 48v 12amp and the total power of the batteries exceeds 50v but when i got on the bike it only accelerates intermittently...... whereas when its on the stand it works perfectly. I strongly believes that the problem lies on the dead battery which is not charging. The charger insted shut off when i tried to charge it.......

I was gifted and FU care a bike from a friend. He didn't have any instruction manual or anything. And He didn't really know how to Set up the display screen and all. I was playing around with it and just trying to figure stuff out without a manual and and f. Y. I.ing it on Utube...of course after I pushed buttons on said display " Coughing and clearing my throat before I continue""SQUIRREL" too late! Apparently somehow I setup a 4 digit password???I have no clue what I did .being how I got the bike 2nd hand ✋️ Fucare ebike pretty much just hung up on me and blocked me now im stuck with a locked ebike and stretched beyond belief! Never even thought of ebikes before and now I am hooked! OR Should I say was hooked 😢well if there's anything anyone knows. It would be greatly appreciated! Thank you in advance and have a blessed Day!
