    mounting third battery need ideas

    I have a 02 21xl magnum and I am going from a 80lb 24v motorguide to a 36v 101 fortex and looking into the battery compartment in the back seems kinda cramped to get another battery back there does anyone have a 21ss extreme or magnum any hull that has the same lay out. With a 36v trolling motor they could post up some pictures of how you have all 4 batteries in the back. Debating on moving my oil tank to the center where my battery charger sits now and putting the 4th battery where the oil tank sits now. Also off hand does anyone know if I will have to change the power wires that are run through the hull havnt had the time to go out and check to see what size they are yet does have a 50amp inline breaker through.

    You shouldn't need new cable since you are raising voltage you will drop amperage.
