What batteries are available for the Assist Slim system?

The collection includes three Slim battery options: the Performance Battery, the Endurance Battery, and the Travel Battery. A charger bundle with the Endurance Battery is also available.

What is the difference between the Slim Performance, Endurance, and Travel batteries?

• Performance Battery: Balanced power and runtime for everyday riding.

• Endurance Battery: Longest ride time for extended sessions and distance riding.

• Travel Battery: A compact, lower-capacity option designed for portability and convenient transport.

How long does each Slim battery last on the water?

Runtime depends on conditions, rider weight, foil setup, throttle use, and the battery you choose. The Endurance battery offers the longest runtime, followed by Performance, and then Travel for shorter sessions or lightweight setups.
