The bike and battery has been great and regular, with no issues until now. Top up charging every now and then as has been under used for a year, always good power on demand.
This time the charge light stays green on a low battery and does not charge. Charger is fine.
Batteries 50 x 3.7 2600 show all at 3.69v except for one line of 4 that are 3.55v. is this a case of 4 dead batteries? Should I replace them and the bms, or go shopping for a new pack?
Cheers. I love my phat tyre ebike!!!!!
