Alright guys i fish LaDue a lot and have a 55lb thrust powerdrive minkotta trolling motor (it has the foot control)...my question is that anfter trolling across the lake and back my battery is almost dead? its a minkotta deep cycle battery. its new and holds a charge just drains quickly...is there anyway to link two battery's together? or do they make something to keep a battery charged on a boat? Its just a two seater bass boat and im just trying to find the best way to get out on the lake and not have to worry about my battery dying...any help would be great guys.
