A strange issue. Built two 100A 4S LFP batteries. Each had a separate and different BMS. Both worked well on a bench for months without any discharge after a proper charge within the levels for each module and battery.
Few months later, after being disconnected from the chargers checked each module again and one was showing a strange 270V (now dropped to 241V)! The other three were just fine at 3.2-3.3V.
Happened with each 4S battery. One module in each, each had a different BMS, different charger and the batteries were not connected
Can anyone here explain this? Can it be repaired?
