Dont really like their overall product though.

Where did you find that it can handle 120A ?

I think it's dreadfully complicated to pass current through a bms. I'd rather just have it balance the pack, and disable the throttle or ignition wire on the controller during an LVC condition.

I measured the current consumption, t's not so bad for this basic design.
- BMS without screen: 8mA
- BMS with screen: 9.1mA
- BMS with screen and relay: 10.4mA
