I hope this isn't a common question - here's the deal. Last year I finally got to fixing a lot of things on my boat, including taking the dorm fridge out I used for over 15 years and replacing it with a proper AC/DC Isotherm fridge, upgrading the sound system and also adding the ability to use a small TV. In short, I want to anchor out more this year but don't want to worry about running the batteries down. What would be the simplest/best way of adding a third battery?
