Bay Pelican has a 12 battery (six volt Golf Cart) house bank that runs everything. Sole exception a small (Group 24) 12 volt battery under the helm which serves the SSB and the backup VHF. The underhelm battery is isolated from the house bank and has a separate charger. It is also five feet above the water line in the event of flooding.

In ten years with this setup I have never needed the Group 24 battery to start the generator but it will do so. During that time I have started main engines and generators on three other boats with that battery.

Charging of the large house bank is done with two large (100+amp) chargers when on the generator. I use a remote battery switch to divide the bank into two banks so each charger charges six batteries.
