looks like there an option for the leisure battery to have a LIN bus shunt as well . .
though its still Relay switched to alternator.

Battery monitoring includes auxiliary battery power management. The monitoring of the
auxiliary battery is done using the J934 battery monitoring computer 2 (on the negative terminal of the
auxiliary battery) and special vehicle control unit J608.
Battery monitoring data enables vehicle reactions, such as increased
alternator voltage or idle speed. The charging relay is open when the auxiliary battery
is fully charged during the journey. The load relay remains open for the next trip.
An optional charging button can be connected to the special vehicle control unit J608. That
enables the secondary battery to be fully charged independent of vehicle functions. A pressure
pressing the recharge button allows you to request the maximum voltage of the alternator and an increase in the
idle speed. The load relay remains permanently closed. This function is automatically disabled at
the end of the journey. The load relay opens. The load relay remains open for the next trip.
The special vehicle control unit J608 can generate warnings and cut-outs if certain states of
are not reached or if a power limit depending on the state of charge is reached.
In addition, the J608 special vehicle control unit can display a load indicator in 10 segments
and the remaining autonomy of the additional batteries until switching off in hours and minutes.
