Re: How do I know how much I need?
Now I better understand. I, perhaps, was very fortunate, 'cuz our boat has a built-in battery box, but it only designed for two batteries, hardly a good start for a reasonable battery bank(s)!, but that was the "thinking" of the boat builder at the time (mid-80s). My PO, though, added a flat platform in another storage area on the boat, so I have almost 400 ah with three Grp 31s, plus a separate smaller reserve bank. Other than having to wire a larger output alternator direct to the house bank (avoiding the switch), not much, actually nothing, needed to be changed.
You're certainly right about the kinds of "issues" facing a lot of skippers.
Thanks for your clarification.
