Frequently Asked Questions
Here you'll find answers to frequently asked questions about controller replacement.
The E-Scooter won't E-Scooter after I replaced the battery—what should I do?
First, check all the connections. Often, a connector isn't fully plugged in, or the battery cable hasn't been reconnected.
Do I need to adjust any settings after replacing the controller?

What should you do if a plug connection is difficult to disconnect?
Always pull the plugs straight out without using force. If necessary, wiggle them gently back and forth to loosen them.
