Windstar has two parallel group 31 batteries as the house bank, and a single start battery with a 20a multi bank smart charger. For winter I top up the electrolyte , and leave the shore power cable connected to the well-covered boat, coiled and hanging from the prop shaft. Charger turned on. Every month or so I emerge from hibernation and connect the boat overnight to an outlet in the yard via a cheater cable to top up the batteries. Seems to work fine. Can anyone see any issue with this approach?
