Does this have a safety to stop itself from draining the battery on a failure? Also, the master controller is programmable correct? I would like data logging if possible as well as balancing/charging/discharging functions. When I get off work I'll compare the two boards but this seems like it is more of what I wanted. =)


To me a BMS should control the on board charger or be strongly integrated into it, talk with the motor controller/inverter and alert the user to any 'off' conditions.
It should output pack voltage/amperage, and should alert if any single battery is higher or lower then the others and try to keep it in sync. If one battery is consistently being a PITA the system logs should show it so we can get rid of the one misbehaving battery.
