The FM+ 650 Battery sits at the intersection of runtime, weight, and cost and is your “go-to” battery option for both Gen2.5 Fusion and MAX+ units.

With 648Wh of capacity, Foil Drive’s 43V architecture unlocks powerful, consistent thrust and endurance for extended surf sessions and upwind/downwind runs to wake riding, pumping, flatwater starts and light eFoiling.

Engineered to work across both the Fusion and the MAX + units, gives riders the flexibility to move one battery between two very different setups.

For MAX+ riders, this is your highest capacity battery, offering plenty of runtime for a full surf session. Fusion riders simply add the FM+ Battery Adaptor for lighter, more maneuverable alternative.
