Battery Replacement
Although it is recommended to use Ninebot battery it is totally possible to use other comparable batteries. The only major difference between Ninebot battery and other after market batteries is special Ninebot software that is pre-installed at the Ninebot batteries. This software communicates with Ninebot app and allows you to see charge level on the app. Other comparable batteries will work fine except giving you reading on the app. You still will be able to see the charge level on the front display.
Taking into account high price of the Ninebot branded battery it is up to you to decide if information on the App is so critical to you.
