20 km/h limit still exist also when i put ext battery.
Any help here?
I just had the same problem. You need to
change the ESC serial number. Unfortunatly it's not so easy to find the right information.
This worked for me (converted Ninebot ES2/ES4 stuck at 22 km/h, after the serial change the max speed was 28 km/h):
1. On a Windows PC with bluetooth install
Ninebot-Flasher by majsi from the Microsoft Apps Store
2. Connect to the Ninebot ES2/ES4 and enter the serial number
N2GTX2222C0077
3. With the cursor in the field press
Ctrl-Alt-A
4. Press the
Write ESC Sn button
After the serial change the max speed was 28 km/h.
