Can you maintain more than one battery at a time?
I know this question may have been asked, but more specifically, I would like to know how the charger would handle multiple batteries connected in parallel. If I have a couple boat batteries and a couple off-road car batteries that I want to maintain over the winter season, could I just connect them in parallel and use this trickle charger? I would still maintain the 12 volts, but the total ampacity of the connected batteries would be larger.
