It is SOP in RVs to charge an auxullary battery along with the primary battery. You'll need ot add a "backflow" circuit to keep from draining the aux batt into the vehicle circuit. I'd check with an RV dealer. --Bill On Sat, 22 Apr 2000 08:45:22 -0400 Barry Andersen <[EMAIL PROTECTED]> wrote: I have become increasingly less interested in hauling my mahoja sized winch battery in and out of the car. My Caravan has a 12volt outlet at the rear. I wondered what would happen if I connected the winch battery to that outlet. Would it charge the winch battery over time? Of course I am interested in not doing damage to my cars electrical system. No guesses please. Thanks Barry RCSE-List facilities provided by Model Airplane News.
