Foil Drive MAX Sport 396 Battery – High Power 40V Battery
The Foil Drive MAX Sport 396 is a High Power 40V battery that strikes a unique balance between capacity and weight. With 396 Wh in a compact, lightweight package, it keeps your MAX setup lighter and more responsive underfoot, for more natural turns, easier take-offs and a livelier ride when pumping between sections or connecting waves.
Why choose the MAX Sport 396
- Lighter, more responsive: less mass and swing weight at the front of the unit make the board easier to turn, pump, redirect and unweight.
- More runtime, same compact feel: 20% more capacity than the original MAX Sport battery, for roughly 20% longer sessions without the weight penalty of the largest packs.
- High Power technology: advanced high-power cells deliver lively, efficient and performance-focused assistance.
- Versatile: ideal for surf, winging, parawinging and downwinding, and a great middle ground between the Sport and the Power / High Power batteries.
Who it is for
Made for MAX riders who want a lighter, more responsive setup with meaningful capacity. Perfect if you already ride the Sport battery and want more runtime (or a replacement, since batteries are consumables), or if you ride the larger Power / High Power packs and want to drop weight without giving up much session time. Best suited to assist-focused riding rather than efoiling.
