The FÄBOARD battery was designed specifically to fit the small, lightweight skateboard. The technology behind the battery design is unique for a powerful electric skateboard in such a small and light body. The goal was to create a battery that would fit the 99Wh requirement for travel with lithium batteries but could also drive a powerful electric skateboard. In the end, we designed a 10C discharging battery (Samsung/LG depending on the supply) which has twice as much power as the 5C discharging batteries found in other electric skateboards. This design has made it possible to use a smaller battery to drive the monster 1800W motor. Visit Link: https://www.ridefaboard.com/products/dualbelt
