i hate this idea. whats the point of having a seperate battery? u want more consistant voltage and more amperage? run 2 batterys in parallel and call it good. if not ur just drGging abound 70lbs for what?? " if u need it??" an alternator loves 2 batterys. its not harder on it.. its eaiser. less draw=less to recharge.
