Callisto currently has 4x 6V golf cart batteries from Costco, but is wired for six: two under the after quarterberth, two at the bottom of the hanging locker beside the engine, and two in a custom box in port cockpit locker. Never any problem starting our 4 cyl VW diesel (850CCA specified), even when battery voltage is low (as low as 11.8V) from fridge running at anchor after a few cloudy days. We have 150W of solar, no shore charger, and two 60A alternators on the engine, one with a manually adjustable regulator to allow for higher charging voltage, although I usually leave it on auto.
Although the wiring done by a previous owner is a bit scary, it all seems to work well. The batteries in the cabin aren't vented, which is something I might try to resolve this winter. I'm not sure if just venting to the area under the cockpit is sufficient? I have considered adding a fan to exhaust some heat from the fridge and engine area to improve fridge efficiency. -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Mon, Sep 23, 2019 at 7:28 AM David Risch via CnC-List < cnc-list@cnc-list.com> wrote: > Flooded since day 1.
