Pairing or Connecting Controller to Foil DriveUpdated a month ago

Pairing or Connecting the Wireless Controller to your Foil Drive System

This is how to re-pair lost wireless link or connection between controller and motor, similar to connecting a Bluetooth device. If you have turned on your controller and connected your battery and your motor is not responding, you may need to re-pair your controller to your Foil Drive.

IMPORTANT: If you have received a replacement V2 controller after the 19th of December 2023 and using an Assist or an Assist PLUS unit, you will need to change battery serial number to enable correct telemetry between your unit and your controller.

To do this, scroll to the menu option "Battery Serial Number" and select the option by holding the power button in for 3 seconds. Once selected, single press the power button until the number reads 6 for Assist, 8 for Assist PLUS, or 11 (For Assist MAX and Assist Slim). Once the number reads correctly, simply single press the cruise button (button 3). 

Follow the steps below to carry this out first, before re-pairing your controller to your unit.
