Hi everyone. I am summoning the cruisers forum wisdom on what to do with my batteries for this winter. The boat is an ericson
32-2. Starting bank is interstate run of the mill starting battery
(I assume it is closed agm
as I can't open it for topping with distilled water). The house has two sets, both flooded lead. One is a Trojan 105 and the other is interstate two 6 volt golf cart batteries connected in series.
I have two solar panels
. 60 watts mono each, with genasun mppt
regulators. The plan was to connect one of the panels
to the starting bank. Then I would connect the other to the house bank (the two golf carts which act as one 12v battery
, plus the Trojan 12v) in parallel so they act as one bank. The other solar
panel would charge this bank. Does that sound ok, or am I doing some big faux pas?
And if everything looks ok electrically, the big question- should I worry that the cold winter will freeze these batteries? It's truly a pain in the butt to take them off the boat so I would rather leave them over the winter layup
in this setup, but if it is better to take them inside I will. Last winter was harsh in nj with temps reaching -10. This boat is new to me hence I am curious what others think. Many thanks for your thoughts.
