    DC2DC charger/GC2 batteries.

    Thinking about adding a DC charger from my truck to my TT GC2 batteries. The charging spec for the GC2 bulk charge is ~10% of C/20 Ah. Capacity of each of my batteries is 230Ah. As there are two batteries in series do I need a charger capable of providing 23 amps or 46 amps?

    Series batteries have the same current so 23A. Your battery combo is 12V 230AH.
