Hi,
I have a LiFePO battery from BMS battery that is about a year old and has had 50-100 charges. Recently the range has dramatically reduced but I am not sure why.
The battery has a BMS - all cells are balanced equally when charged and when discharged. The bike works fine when the battery is fully charged. The issue is that the battery cuts out when going uphill after about 5 miles or so. The battery used to be able to do much more than this before (not sure of the range, but easily managed 20 miles). It seems likely that the problem is with the electrics or electronics. It would be useful to know how to determine if there is an issue with the BMS, the charger or the motor controller.
I am at a bit of a loss and wondering whether I should start replacing parts.
I don't believe the cells are dud because the battery gets to over 42v (36v battery) and all cells are balanced.
I would be grateful for any useful suggestions.
Regards,
Justin
