Just want to say I've been trying to figure out what was wrong with a similar battery which uses the same charger and wouldnt charge above 36v, I had done everything and it wouldn't work until I found your video and did the disconnect of the negative and short it down and now it's charging so I'm very hopeful! Just want thank you very much and my wife's sister will be very happy that she can use her bike again
At least you got to the bottom of it should have given a link to where you gained the fix its just an unwritten courtesy. The balancing wouldn't hurt thanks for the content and you're a kind person helping out
My electric bike started out at 36v, then I went to 48v, then 52v now I'm going to try 60v. I just keeps getting faster each time. Awesome video as always Morten . )
I think you did indeed need to bring all cell groups up to a common level and the overall battery to at least 35v. Otherwise if you reset the BMS it would have seen the same condition that caused it to block charging before. Well done !
Thanks for the video. Even though it is not similar to mine, just realising that these batteries have a fuse somewhere cure my problem with a replacement.
Hi, same thing, a friend was given a non working 14" Murtisol Ebike. Battery is 36v 6 amp hours. I have new charger, 42v 2amp, its working fine and has been tested. It brought battery up to 16 volts and charger light turns green. Tried turning on and off a few times. One video said that can reset the BMS, it did not in this case. So I will open it up and see if resetting the BMS will work.
I think the lowest cells with 2.6-2.7V should have been balanced, so that's a good thing. But actually, yes, often after "fixing" a deeply discharged lithium-ion pack by charging the cells individually back up to 3V or above, you then need to reset the BMS by cutting its power. I've seen that with an old laptop battery I fixed (there were no replacement batteries available in 2018 for this cheap 2011 200€ laptop), and I've heard that it even works that way also on iPhone batteries. So this is quite a common thing.
Acctually biltema had this programed in bms so it stop taking charge after some years.. reset bms and good to go. (If there ist any other issues offcurse

Batteridoktorn now just shorten the RST (reset) signal on the board to ground.

Hello .... Is there no problem in charging Li-Ion Batteries with the power supply ? I am scared to do so ...., Li-Ion cells not have a special charging algorithm ? like CV/CC ? could you explain a bit , please ?
This is just a mater of charging it up enough for the charger that comes with the bike, to be able to take over. As long as you charge it slowly,, it is fine.

Thanks for your effort. Your video was entertaining. However I think you should have left a link to the person who published the TH-cam video you mentioned that actually told you exactly what to do in order to fix the battery (i.e. how to reset the BMS), otherwise, it's not clear whether your effort accomplished anything for those that need that information. You spent most of the time showing how to iteratively balance charge levels of various cells and admitted you weren't sure if that was root cause of issue.
The battery has a small CPU with "planned aging". After a number of charges the battery simply stops working to force you to buy a new one. More or less a scam. What you did was to reset the aging counter by draining the CPU from power.
21:26 "I'm going to help a friend with his shit." O.o? Costive bowel, a crowbar is needed? O.0! Well, how much would the service have asked for opening the battery case, pushing that reset-button and sending it back? Bet your bottom dollar a new battery would have been cheaper… Or, well, don't bet your bottom dollar, it might be the last one left, once you deal with companies like those.
Well get your shit together :-) I sayed Shed!! :-) My interns mom, had gotten the repair prices of 2500,- and a new prices of 4000,- I was able to find a new one for 2399,- :-/ so someone was trying to make a fast buck.
Well done, it's alive again :-D Im not impressed by that charging system, the designer needs a good slap with a battery lol. It should have blinked a light on the battery labeled recovery, while the controller pulse charge the low cell voltage. Or at least a reset button on the battery. Silly designers.

I resscued 3 or 4 Lipos in my rc area with this solution. You need a "stupid" charger to "initalize" the batteries.
Thank you!
are you left handed?
Most Geniuses is.... :-) Yes
21:26 "I'm going to help a friend with his shit." O.o? Costive bowel, a crowbar is needed? O.0!
Well, how much would the service have asked for opening the battery case, pushing that reset-button and sending it back? Bet your bottom dollar a new battery would have been cheaper… Or, well, don't bet your bottom dollar, it might be the last one left, once you deal with companies like those.
Well get your shit together :-) I sayed Shed!! :-)
My interns mom, had gotten the repair prices of 2500,- and a new prices of 4000,-
I was able to find a new one for 2399,- :-/ so someone was trying to make a fast buck.
Flott video.
Hi @bjoernandersen8287
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
Well done, it's alive again :-D
Im not impressed by that charging system, the designer needs a good slap with a battery lol.
It should have blinked a light on the battery labeled recovery, while the controller pulse charge the low cell voltage.
Or at least a reset button on the battery.
Silly designers.
I agree,, the info you get,,, sucks
Hej, vil du hjælpe mig med min batteri? Den vil ikke lader 😞 helt nye oplader men den siger ingenting. Jeg betaler for det hele (jeg sender hjem til dig) jeg håber du vil hjælpe mig med 🙏
Sorry,, I do not want to get in to this,, I have plenty of projekts I should be working on,, sorry
Kender du nogen der kan gøre det? Jeg er helt uden hjælp 😭😭😭
I think it's 5.61
If you say so :-/
we have the same batteries, they are not the same capacity. It's not a good one.
