DESCRIPTION

The FM+ 650 Battery sits at the intersection of runtime, weight and cost, and is the go-to option for Gen2.5 Fusion and MAX+ units. With 648Wh of capacity, Foil Drive’s 43V architecture delivers powerful, consistent thrust and endurance for extended surf sessions, upwind/downwind runs, wake riding, pumping, flatwater starts and light eFoiling. It works across Fusion and MAX+ setups: add the FM+ Battery Adaptor for Fusion, while MAX+ riders get the highest-capacity battery and Fusion riders gain a lighter, more maneuverable option.
