I currently have two battery banks consisting of 2 6V T105's wired in series per bank. They're located above the starboard lazorette in the cockpit which I believe is the original battery location designed by CSY. I also have a separate starting battery located in the engine room. When I look at boats being advertised for sale, I see they have 6 to 8 T105's for their housebanks. Where do they have them located? I would like to increase my battery capacity and would enjoy hearing what other's have done.
