I have a housebank, which is charged by a Smart Solar MMPT 100/50 and connected and supervised by a BMV-712 via shunt. In addition I have a starter battery which is not connected at all to this house system. However I would like to monitor the starter battery also via the auxiliary input of the BMV-712.

Issue is now that the starter battery is about 5m away from the housebank and a cable connection for high loads would be quite complicated. From the BMV-712 manual I did see that normally I would have to connect the minus of the starter battery also to the shunt via a very thick load cable and an additional thin plus cable to the B2 port of the shunt.
Is there an easier way to connect and monitor the the starter battery via BMV-712?
