It would be beautiful if FM made a swappable battery. Several fellow riders have taken their boards apart and the battery just slides into the channel. Woulda been great if it could have been designed so it could be removed / replaced without taking the entire unit apart.
@sfctac Custom pairing password should allow you to re-pair to another device once set. Also, Bluetooth LE uses minimal battery, the little tracker chips you can put on a keyring last a year on a watch battery
