I had a C&C25 with NO charging
at all (solar panel was stolen...thank you very much marina security!). Pull start outboard
(no charge circuit). All the same stuff you mention...led lights, autohelm
, plus we had a portable DVD
Originally had 2 type 24 batteries. One died. Got rid of it. I would charge the one battery
overnight at the dock
. It was then good for a solid week of cruising using all our lights, authelm (all day), etc. After a week (seven days), it would be down to 12.0 - 12.1 volts.
With your excellent solar
panel, you could likely have a single
type 24 battery
. If you are on a really tight budget
, or have no space, it would likely be fine. Two would be better. The type 24, deep cycle, lead acid battery is about the cheapest you'll find.
As others have said, separate battery for engine
