Previous Error Code: Ninebot Max Error Code 22 - Next Error Code: Ninebot Max Error Code 24

Cause

This error is caused when the battery has the default number, similar to Error 35.

The serial cannot be 3GA0016A1A0001, 3GB0016B1B0001, 4GA0016A1A0001, or 5GA0016A1A0001.

Fix

Change the BMS serial number using an app like Ninebot Flasher or Ninebot IAP.

Even changing the serial number by one character should be enough.
