I am wiring the HV Relay/LV Relay circuits in series to a Gigavac 240 contactor on the B+ lead. This will disconnect the pack in the event of either a High or Low Voltage condition. Sergio and others have designed some really cool relay laddersthat have some advantages and there's some great threads on the topic. I'm more of a Keep It Simple S.... kinda guy, less parts - less to fail.
I'll be mounting the Gigavac to the tub wall so I can only run the lead B- to the terminal board and coil up the HV/LV Relay wire to the Gigavac until I put the pack into the cart.
Anyways there's of ways to accomplish this!
