Hello. I’ve had the same problem. My original battery failed and two replacements have also failed. The cell voltage seems fine but the “pack” voltage where the BMS board connects to the rest is 2.2 V.

It might read 2.2 V because the BMS FET has turned off. When trying to charge the pack voltage fluctuates between 10~11 V.

One replacement failed because the bus wire that connects the cells rubbed against the sharp aluminum edge of the case and shorted.
