I would ditch the 1,2 switch in favor of the acr system. In my opinion it’s a far better setup. You can then run one house(deep cycle) and one start battery and the system will regulate the charge itself. The switch is just on/off. Starting on a deep cycle will wear it out prematurely as will deeply discharging a starting battery running electronics and riggers all day not how they were designed to be used.
just my opinion maybe worthwhile when it’s time for new batteries?
