Foil Drive MAX Sport High Power 396 Battery

Looking for a unique balance of capacity and weight, and a more responsive feel from your MAX setup? The MAX Sport High Power 396 Battery delivers 396Wh of capacity in a compact, lightweight package — 20% more runtime than the original Sport Battery — with less swing weight for a more natural, lively ride.

The smaller size keeps the system lighter and more responsive underfoot, resulting in more natural turns, easier take-offs, and a more lively ride when pumping between sections or connecting waves. With less mass and swing weight in the front of the unit, the board feels easier to turn, pump, redirect, and unweight.

For pumping, surfing, downwinding, wing, and parawinging, this makes a noticeable difference.

Ideal For

• Surf sessions where board feel and responsiveness matter
• Lighter riders who don't need the largest MAX battery capacity option
• Winging and parawinging where a lighter, more compact system is easier to manage
• Downwinding where pumpability, low drag, and board control are essential
• Anyone who prefers a more compact Foil Drive setup with more capacity than both the original Sport and MAX Travel Battery

Runtime

• Efoiling: Not recommended (short runtime)
• Assist — Heavy Motor Usage: 25–40 minute session*
• Assist — Light Motor Usage: 30–55 minute session*

*Runtime is variable and depends on rider weight, ability, motor usage, board and foil selection, conditions, riding style, battery age, and temperature.
