Hi all,
I never quite got my head around this one so an expert opinion is much appreciated!
Starter battery: Exide EP600 70Ah AGM
House battery: Pegasus SB12-105 100Ah AGM
VSR: Blue Sea PN 7600
Normally House & Starter batteries are only connected when driving van as you'd expect.
However, if I think I may use more than, say, 80Ah before the next drive it would be nice to draw from both batteries to prevent the voltage on the house battery dropping too low (by switching the VSR to 'always on').
I would reset the VSR before starting the engine (to avoid the starter overloading house battery wiring) & have a emergency booster battery which can start the engine if I get my sums wrong & wake up to 2 flat batteries lol
When I switch to 'always on' it would be after a drive when both battery voltages are the same.
Issues?
