Question. I have start and house banks. I want to charge my house bank from my engine when its running. Obvious answer is a VSR but this allows current in two directions which may mean the house bank on solar or 240v charger will charge the start bank.
I should mention start bank is normal lead house bank is agm.
I have been looking at DC-DC chargers. This allow current in only one direction. But i am struggling to fine one that will charge an AGM to its specifications.
Does anyone have any experience in this area?
Or maybe a solenoid that joins start to house only when ignition is on? But this would mean start current would come out of the house batteries...
A bit fat diode?
