Considering the location it wasn't a quality unit, and if it was it was guaranteed to be stolen and likely charged improperlyEastwood said:Yeah crazy! I would like to know the details like what type of cells, did he bypass the bms etc.
It could’ve been just another cheap E bike from China with a ticking time bomb for a battery.

Because of cheap BMS, what should be done about that? Is there a way to "verify" a good BMS (or battery)? Should we just outlaw all the NMC batteries and only allow LFP batteries?

Say you had a 14s battery with a shorted cell group at 0V and dud BMS that didn’t stop charging- the other cells would maybe see 4.5V but surely that wouldn’t be enough to cause a fire
