is going to come with 3x flooded batteries
Exide ER 350 80AH with 2x being house bank and the remaining being the starter. I’d like to add one more to the house bank, however, I can’t find this battery
in the US. I’d like to be able to take the third starting battery
and make it a house battery and replace with some flooded battery in its place for the starter. What considerations do I need to do this? Would I need a DC to DC charger
? Yandina battery switch? I have attached the wiring
diagram per the owners manual where you can see that everything at factory is wired straight to the switches.
