Have gotten by with the cord through the hatch, but wanted something a bit better......
I have wanted to add a AC outlet to my front battery box, but wanted something small to conserve space. So I repurposed a gang box from Home Depot. 15 amp blue sea breaker, power indicator, reverse polarity indicator, and single plug. Will connect my Victron 15 amp blue smart battery charger (Bluetooth enabled) to the single plug. Will also run a circuit to my rear mounted air conditioner.
