I recently switched our four 6V flooded batteries in our class A motorhome to two 12V lithium, and want to install a BMV-712 to monitor battery SOC. However, looking at the instructions, I'm having a difficult time figuring out where to place the smart shunt in our system. The instructions say to place in between the battery negative and all loads on the system. But our system has multiple chassis grounds, and only the inverter is directly connected to the battery bank -- all the other loads are connected to a different chassis ground. I'm relatively new at this, could someone give me a pointer on where the shunt should be installed? Do I place it in between the battery and the inverter like in the attached diagram? Or do I need to track down all of the chassis grounds and connect them all to the shunt? I looked through the forum posts and couldn't find an obvious match.
