Description
Description
The Waydoo FoilBoost 400Wh Battery is a genuine replacement or additional battery for the Waydoo FoilBoost Assist Kit. Keeping a second charged pack ready gives you more flexibility for longer days, repeat sessions and locations where recharging between rides is not practical.
Important: the displayed £529 price is for one complete 400Wh battery pack.
This is the battery only. A FoilBoost motor, charger, charging station, remote and mounting hardware are not included.
Why add a spare FoilBoost battery?
- More usable time on the water: keep another battery charged for a second session rather than waiting for your original pack to recharge.
- Useful for full days and trips: a practical upgrade for downwind sessions, light-wind winging, SUP foiling and locations without convenient mains power.
- Less pressure on session planning: rotate charged batteries between rides while allowing the used pack to cool and dry properly before charging.
- Genuine Waydoo compatibility: designed specifically to work with the Waydoo FoilBoost system.
Who is it for?
This battery is for riders who already own a Waydoo FoilBoost and want additional capacity, or who need to replace an existing FoilBoost battery. It is particularly worthwhile when you regularly foil away from home, ride more than once in a day or share the system with another rider.
If you are still choosing your first electric assist setup, browse our complete foil assist systems or read our Foil Drive, Duotone and Waydoo foil assist comparison before purchasing individual components.

Compatibility advice
This battery is designed specifically for the Waydoo FoilBoost Assist Kit. It is not a replacement battery for a Waydoo Flyer ONE, Flyer ONE Plus, Flyer EVO eFoil or Subnado sea scooter.
For other replacement power products, visit our foil-assist and eFoil battery collection. You can also browse eFoil and foil-assist spares and accessories for compatible parts needed to maintain your wider setup.
Battery care and charging
Use only the correct Waydoo FoilBoost charging equipment and follow the instructions supplied with your system. After riding, switch the system off before disconnecting the battery and allow the pack to cool before charging.
- Do not charge a wet, damaged, swollen or unusually hot battery.
- After salt-water use, clean the exterior as directed by Waydoo and dry the battery and connections thoroughly.
- Charge on a dry, stable and non-flammable surface.
- Remain nearby while the battery is charging.
- Store in a cool, dry place away from direct sunlight, heat and flammable materials.
- Follow Waydoo’s recommended charge level and maintenance routine during longer periods of storage.
Buying advice from The SUP Company
One spare battery is the sensible upgrade for most private FoilBoost owners.
Runtime will vary according to rider weight, foil choice, water state, power setting and how frequently the motor is used. A second pack does not change the performance of the motor; it simply gives you another fully charged power source for your next ride.
Still deciding whether FoilBoost is the right platform? Explore our full Waydoo range, read our detailed guide to what the Waydoo FoilBoost offers real-world foilers, or contact The SUP Company for practical compatibility advice.
Frequently asked questions
Is the £529 price for one battery or two?
The £529 displayed price is for one complete 400Wh Waydoo FoilBoost battery pack.
Does the battery include a charger?
No. This listing is for the battery only. Use the correct Waydoo FoilBoost charger and charging station supplied with, or purchased for, your FoilBoost system.
Will this battery fit a Waydoo Flyer eFoil?
No. This battery is specifically for the Waydoo FoilBoost foil-assist system and is not interchangeable with Waydoo Flyer ONE, Flyer ONE Plus or Flyer EVO eFoil batteries.
Will an extra battery make my FoilBoost more powerful?
No. It provides additional available energy for another session but does not increase the motor’s thrust or top power output.
Should I choose one spare battery or the 2-pack?
One spare is normally enough for personal use and gives you a straightforward second-session option. The 2-pack is more suitable for shared equipment, frequent full-day use or riding locations where mains charging is difficult.
Can I take this battery on a passenger flight?
A 400Wh lithium-ion battery is above the capacity normally permitted as passenger cabin or checked baggage. Do not book travel on the assumption that it can fly with you; contact the airline and a suitable dangerous-goods freight specialist before arranging transport.
Where can I get help with compatibility?
