Smart Shunt dual battery

I have conflicting technical information from Victron on the correct way to connect a DC Smart Shunt in dual battery system. I plan to use a VSR to link the batteries

Please see pics from Victron. I plan to use the aux input to monitor start battery voltage.


Which side of the DC shunt should the start battery negative terminal be connected?


I think this is correct with the starter battery connected to the smart shunt system negative.

This picture shows the starter battery negative is connected to the smart shunt battery negative.

If you are going to charge the main battery from the start battery via a VSR, use the top diagram.
