I am building this basic system but with the 600 amp CAN bus current sensor instead of the current shunt and I will add a sleep switch.
Pingeye3 provided me with a CAD wiring diagram for the first pack I did. We have since changed from using two disconnect relays to using just the single Gigavac 240 contactor and moved a wire to allow the system to be reset easier. The BMS HV relay and LV relay connections are wired in series using the Gigavac to isolate the battery pack in the event of either high or low voltage condition. I will post the wiring diagram after I have made the corrections. More on this later...
