dc-dc charger

Hello, friends. Need advice.

I have an motorhome with "Victron Energy Orion-Tr Smart 12/12V 30A DC-DC Isolated Charger" to charge my house batteries. But sometimes i will need to feed the starting battery a few amps from the house battery (listening to radio with engine off, using other accessories).

Is there a way for my isolated charger to short input and output? If not, would it be ok to short it manually though the switch?

No this cannot be done. The Orion does not support it, strictly one way operation.

Shorting with a switch will cause high current from the high to low battery.

Ideally put in a second isolated Orion, switched. But you may need to tweak the settings, to get it to kick in.
