Why riders choose it
- The Fusion 860 Battery delivers long-range power, efficiency, and intelligent management, providing 40 percent added thrust with 2x the runtime of a MAX Power battery and 5x that of the SLIM Performance battery.
- Built on a higher 43-volt architecture with 860 watt hours of capacity, it unlocks hour-plus to multi-hour sessions in a compact, hydrodynamic form. The integrated one-piece molded design combines the battery and nose cone as a unified sealed unit, improving water flow, strength, and durability, all while balancing weight directly over the foil's center of lift.
- Internal thermal management keeps temperature stable and maintains consistent power through the full discharge curve, ensuring smooth thrust delivery from start to finish. A dedicated Bluetooth module provides accurate battery data to the Foil Drive App and the V3 Controller, giving clear percentage and status readouts for confident decision-making for longer runs and open-water voyages.
- Charging and care are even simpler than ever before. The 1.45-hour fast charger includes a storage mode for long-term battery health, while the Battery Caddy can discharge to storage levels or function as a portable power bank with USB-A and USB-C ports to charge controllers, phones, laptops, or other devices.
- This high-capacity battery is built for long sessions, reliable power delivery, and high system utility.
- Proper care is essential for battery longevity. Please see your Battery and Charger user manuals for added.
