DUOTONE eBattery 7A (1Pcs)

The air travel-friendly Foil Assist batteries come in a convenient format and feature an average battery runtime of 25 to 40 minutes.

Besides the battery set, we also offer single batteries for replacement.

Please note that you need to plug in two batteries to make the Foil Assist work. 

Our high-voltage lithium polymer batteries (LiPo) have been specifically designed for the Duotone Foil Assist system. Please note that you need to connect two batteries to activate the Foil Assist.

To make your foiling experience with the Foil Assist truly limitless, our batteries comply with air travel regulations and have a capacity of 159.6 Wh – just under the 160 Wh limit for air transport*. This means you can take your Foil Assist anywhere and explore completely new spots.

The battery runtime depends on various factors, including your foiling skills, weight, conditions, board size, speed level, and the efficiency of your foil. Typically, the runtime ranges from 25 to 40 minutes. We recommend investing in a second set of batteries so you can fully enjoy your time on the water without significant interruptions.

The batteries can be easily activated with a simple power button. Next to it, you will find four indicator lights that show the charge status of the battery – from empty to the optimal storage level (two or three lights) to fully charged.
