I searched the forum and I apologize if I missed the same question(s) ...
I have a truck and 5th wheel RV/camper and I want to be able to charge the RV batteries using the Victron DC-DC charger(s).
The truck has two alternators (125ADC each = 250ADC total) and two batteries. Best I can tell is the batteries are wired in parallel (12VDC) and both are used as starting batteries with no isolation between them. Truck is a 2013 GMC Sierra 2500HD
1. Should I go with one or two of the 12/12-30A units? The DC-DC charger(s) will be mounted in the RV.
2. I assume I should I get the Isolated unit(s)?
3. How do I wire it/them in to the battery(s)? Do I connect both units to one battery or one unit to each battery?
Thanks for any and all help!
