The Foil Drive Slim Endurance Battery is the larger SLIM battery with 241Wh capacity. The Endurance Battery is great for those who are wanting to lengthen their runtime with the Assist Slim, however, due to the lower voltage this battery does not provide the same level of thrust and overall ride experience as the Slim Performance Battery.

The Slim Endurance Battery is the only Gen2 battery that runs on a 28V system. This means you must use the 28V Standard Charger 4A with this battery. DO NOT ATTEMPT TO CHARGE THIS BATTERY WITH A 40V Charger!

YOU MUST READ this Critical Battery Configuration information about the usage of the 28v Slim Endurance battery.

As with all Gen2 Foil Drive batteries, the Slim Endurance Battery is certified IP68 rated for increased protection and peace of mind against water and dust.

The single power plug contains larger connectors that provide power to the Foil Drive unit and smaller connectors for charging the battery. The included dust cap provides extra protection during storage & transport.

Only compatible with Foil Drive Assist Slim.
