I cut a piece of marine

. Cut a couple notches on each side to run a tie-down strap through. Put a small "leg" support on the liner (port) side of the board.
Then I glassed it to the hull
and liner. Put a strap through the notches and that holds the battery down. Drill a hole into the bottom of the chart table for the wiring.
The 3rd battery is a 12v group 24 that is my "backup" battery. The two under the chart table are 2 GC6's (Golf Cart) batteries in series. The GC batteries are wired to "1" on the battery switch, the other battery is "2". Standard procedure for me is to leave the switch on "1" all the time. For everything - starting, house loads, etc... Only if the main battery gets killed do I switch the other one in. (Never had to so far)
I've got a fridge and an autopilot
- with a 160W solar
panel the boat pretty much never runs out of power - as long as it's not too cloudy.
