Center console with twin Yamaha 150s, two start batteries and a house battery. Looking to replace my old flooded acid house battery with an AGM, but concerned that the charging system might need updating. My alternators put out max 35A each. Both of my start batteries are wired to Blue Seas ACRs and then to my house battery. The ACRs won't regulate charging, just act as an on/off switch according to Blue Seas rep. I've attached a diagram of my system. The only update to the diagram is a cable running between the negative terminal of the house battery to the negative of one of the start batteries. I appreciate any help.
