Foil Drive MAX Sport 396 Battery – More Runtime, Less Mass
The MAX Sport 396 Battery sits between the lightweight Sport Battery and the larger Power options: 20 % more capacity than the original Sport Battery – yet lighter and more compact than the High Power Battery. High Power cell technology delivers greater energy density in a smaller enclosure, reducing swing weight at the nose and making the whole setup noticeably more responsive underfoot.
Less mass at the front of the system means more natural turns, easier takeoff, better pumpability, and sharper control when redirecting or unweighting. For surf, wing, parawing, and downwinding the MAX Sport 396 is one of the most effective upgrades for an existing MAX kit.
Runtime Estimates
| Usage Type | Runtime |
|---|---|
| Assist – Heavy Motor Usage | 25–40 minutes |
| Assist – Light Motor Usage | 30–55 minutes |
| eFoiling | Not recommended (insufficient runtime) |
Runtime varies depending on rider weight, ability, motor reliance, board and foil selection, conditions, riding style, battery age, and temperature.

Who Is the MAX Sport 396 Battery For?
The natural upgrade for MAX riders already running the Sport Battery who want more time on the water without losing the compact, lightweight character of their setup. It also makes sense as a replacement for an ageing Sport Battery (batteries are consumables), or as a step down for riders switching from the larger High Power Battery who want to shed weight without a significant drop in session length.
