Assist MAX+ Batteries

This collection includes the FM+ 650 Battery and in 2027, the FM+ 430 Battery.

Ride time varies depending on rider skill, weight, gear setup, conditions and how the system is used. With the FM+ 650 Battery, expect approximately 31–52 minutes of e-foil runtime or 40–70 minutes of surf runtime. These figures are indicative real-world averages based on an 80 kg rider and specific test conditions, and actual runtime will vary depending on motor reliance, throttle use, touch downs, falls, water conditions and riding style.

Yes, FM+ batteries are compatible with the Fusion system with an adapter.

Note: FM+ batteries are not compatbile with existing Assist MAX systems.
