I have a setup with two 12V batteries. They are normally paralleled, but each has its own breaker and battery fuse. They are LiFePO4 with internal BMS.
What I am looking to do is monitor the terminal voltage of both, and generate an alert if there's a significant difference. That could happen if there is significant current flow and either battery's breaker has tripped, fuse has blown, or BMS has disconnected it.
It seems the midpoint voltage monitoring of things like the BMV-712 is almost what I want, except that it expects the midpoint voltage to be 6V for a 12V system. It doesn't appear that there's any way to configure it to expect two 12V voltages instead of 6 and 12.
Is there any product in the Victron ecosystem that does what I'm looking for?
