Have you ever come across dangerous ebike batteries with faulty bms's or extra functions that causes the error?
and did you solve it?
Like if the problem was with the cells, the bms or extra functional items like a usb unit, light unit or battery level indicator unit being the culprit of the problem?
I came across it recently and doing what I can to find out the reason WHY it occurred. When I solve it I will post an update and updates as I go forward in my investigation.
The prime suspects as of now is the bms but there is also a draining unit caring for the indicator and a rear light that drains via positive battery and a connection to the bms p- (power minus) which gives out about 8 volts when bms is switched off.
Suspects are as follow:
BMS. Replaced awaiting confirmation.
Light unit on at standby. To be tested next.
Indicator unit draining when off. Not yet tested.
The problem will only occur possibly when the battery is at the low point of 0% SOC and as such will only fail until that event occurs which it will finally but at different times on different batteries. (Why it occurs is that the drain starts at leven when the cells differ alot in voltage and drains fast even if the level of drain or ghost drain is low it will kill cells and cell groups quickly which it can't at higher level of % SOC. )
