MAX Sport High Power 396 Battery

A unique balance of weight, runtime, and performance.

Looking for the ideal combination of battery capacity, reduced weight, and a more responsive ride feel? The MAX Sport High Power 396 Battery delivers exactly that through its compact size and advanced high-power battery technology.

By reducing overall system weight and swing weight at the front of your setup, the MAX Sport 396 creates a more natural feel through turns, easier take-offs, and a more lively ride when pumping, connecting waves, or accelerating onto foil.

Whether you're surfing, pumping, downwinding, winging, or parawinging, the lighter and more compact design improves maneuverability, responsiveness, and overall board control.
