All Radinn batteries and jetpacks are delivered with factory settings and have to go through a manual onboarding in order to be activated. You must download the Radinn app to complete this onboarding (see article Onboarding your jetboard and battery).
In addition to onboarding your jetboard, the app has many other features including unlocking new performance settings, updating your firmware, customizing your jetpack speed, and analyzing your rides.
Note that, in order to download your latest rides, the battery needs to be toggled (disconnected and reconnected) for the system to finalize and compile new logs. Also note that you need to download rides before accepting firmware updates, as an update will erase all data.
