Oh, and for the float charger is great mind set, don't forget if you set the float for 13.6 or so, and don't do anything "fancy" my memory is telling me you only get about 80% of capacity. Seems like some of the power one charger wall warts do a 14.6 volt end point constant current then pop over to a float. 'Grif' N7IVS
