Solar battery charger
My boat is stored on a lift in my back yard. I use it about once per month. The boat has two 12V marine batteries and a parallel switch. If I install a solar charger, will it maintain the charge on both batteries without me having to move the leads or change switch settings? Got the same question about an electric trickle charger. Will a 12V trickle charger handle two 12V batteries wired in parallel?
