I found out the hard way my batteries are at the end of their serviceable lives. at this point im going to start making a plan for next season to upgrade the battery setup. I don't think I will need to go the route of an inverter , since I really don't use any AC functions while at anchor. my boat has the typical 2 battery bank for port / single starter for stbd. my genny is removed so I have the space under the seat with the gen battery leads in place. can I install a 2 or 3 battery deep cycle bank to the genny starter leads and will that feed right to the 12v side of the panel due to the fact that it should have been part of the charging system? I have the stock 30a promariner with isolator.
