Second 12v pack completed the capacity test. The pack pulled 284AH.
Part way through the test I found a cell off by .2 volts. I stopped the load, disconnected the BMS, pulled the bus bars off the misbehaving cell, cleaned the terminals, checked the voltage, found it to be back in line with the others, reassembled the pack, and resumed the test. That cell was the cell that ultimately tripped the low voltage disconnect, but not by very far. My presumption is that the high resistance connection drained it a little faster initially. when I recharge this pack it will be interesting to observe the JBD BMS’ balancing functionality.
