Installation Instructions
The Yungeln Electric Scooter Controller is designed for straightforward installation and disassembly. Please follow these steps carefully:
- Preparation: Ensure your Segway Ninebot Max G30 scooter is completely powered off and the battery is disconnected before beginning any work.
- Access the Old Controller: Carefully locate and remove the existing scooter controller from its housing.
- Wiring Connection: The new controller's wiring is generally color-coded to match the motor wire butt joints. Connect the wires as follows:
- Connect the red and black wires to the XT60 power supply.
- Connect the green wire to the motor power.
- Connect the blue wire to the motor power.
- Connect the yellow wire to the motor power.
- Secure the Controller: Carefully place the new controller into its designated position. Ensure that the protective plastic film on the blue thermal adhesive at the bottom of the controller is removed before securing it.
- Final Check: Double-check all wiring connections to ensure they are secure and correctly matched. Reassemble the scooter's housing.
Important Note: Some users have reported that the wires leading to the XT60 power connector can be loose. To prevent them from detaching, hold the back of the wires firmly when plugging the connector into the battery.
Firmware Information: The controller may come with firmware version 1.2.7. If you experience a high-pitched noise from the rear wheel after installation, updating the controller's firmware to version 1.8.11 or newer is recommended. Custom firmware flashing is possible using tools like Scooter Hacking Utility, though it may require multiple attempts for successful completion.

Maintenance
To ensure the longevity and optimal performance of your Yungeln Electric Scooter Controller, adhere to the following maintenance guidelines:
- Periodically inspect all wiring connections for any signs of wear, corrosion, or looseness. Re-secure any loose connections.
- Keep the controller area clean and free from accumulated dust, dirt, and debris, which can impede heat dissipation.
- While the circuit board has a waterproof coating, avoid exposing the controller to excessive moisture or direct water spray to prevent potential damage.
- If the scooter is to be stored for an extended period, ensure it is kept in a dry, temperature-controlled environment to protect electronic components.
Troubleshooting
- Scooter Not Powering On:
Check all power connections, especially the XT60 connector, to ensure they are fully seated and secure. Verify that the scooter's battery is adequately charged. - Unusual Noises (e.g., high-pitched sound from rear wheel):
This symptom might indicate that the controller is running an older firmware version. Consider updating the controller's firmware to 1.8.11 or newer, as this has been reported to resolve such issues. - Inconsistent Performance (e.g., erratic speed, poor acceleration):
Re-check all wiring connections for proper contact. Ensure the controller is correctly seated within its housing and that there are no obstructions affecting its heat dissipation. - Error Codes Displayed:
If your scooter's display shows specific error codes, consult your Segway Ninebot Max G30 scooter's original user manual for detailed interpretations and recommended solutions. - Difficulty with Firmware Flash:
If attempts to flash custom firmware are unsuccessful, try multiple times. Ensure you are using the correct flashing tools and following the procedure precisely.
