Hi all, I bought a 48V downtube battery for an ebike conversion, the battery would not fully charge only reaching around 51.2v then not holding its charge very well, I did get to replace that battery, thee aforementioned battery now will not charge no lights on the battery power indicator it just died, the battery has been kept indoors in a warm environment, yet now it won't even charge up at all, I'm baffled by this, can anything be done to bring this battery back to life?
Any help would be much appreciated. Thanks Stevie.
may have got a faulty batt from the start. if its out of warranty, (old) then it could have been stored improperly which reduces capacity. there are tips to prolonging li ion battery life which should be followed
