How might I set up the Victron BMV702 relay to control a battery isolator device (a Battleborn lithium battery isolation manager)? I want to be able to disconnect charging amps from the alternator when the house Battleborn lithium bank reaches a certain voltage during a long drive. I have Victron solar charger and 600 roof watts to finish charging the 300 amp hour bank with more control than the alternator. This is in a Mercedes Sprinter mobile home.
