Firefly Foil Assist Battery Pack

The Firefly Foil Assist Battery Pack is a spare or replacement battery pack for the Firefly rider-mounted foil assist system.

Each pack gives you approximately 583Wh of energy, providing the power and capacity needed for repeated starts, long runs and extended foil assist sessions. Runtime will vary depending on rider weight, foil setup, conditions, throttle use and riding style, but typical use is approximately 40-120 minutes.

A spare battery pack is the simplest way to extend your session. Charge one, ride one, or take additional packs with you for longer days on the water.

The battery is designed to be worn securely at the hip inside the Firefly system, keeping the main power source off the board and helping preserve the clean, natural feel of your foil setup.
