All Radinn batteries and jetpacks are delivered with restricting factory settings and have to go through a manual onboarding to be activated, and this is done via the app. (See Onboarding your jetboard and battery) But the app has many other features too, you can upgrade your performance settings, do firmware updates, customize your jetpack speed, and analyze your rides etc.
Note that in order to download your latest rides, the battery needs to be disconnected and reconnected for the system to finalize and compile the new logs. Also note that you need to download your rides before accepting firmware updates, as that will erase all data.
