Assist Plus Batteries 

Standard Battery

The battery is purpose designed, built, and tested especially for the Foil Drive Assist system. Every battery has been carefully manufactured and extensively tested in house, featuring a built-in Battery Management System (BMS) to ensure safety. The BMS manages the charge rate, balance of the individual cells, low and high voltage cutoff, internal resistance and temperature monitoring.

Small Battery

The Small 4.2ah Battery is perfect for Wing Ding riders or competent Down Wind Foilers who want to reduce weight for pumping and turning and only need to use full power for very short periods to get up on foil.
