If you are unsure about any step, it is highly recommended to seek professional assistance.

4. Operation

The mainboard controller operates as the central processing unit for your electric scooter. Once correctly installed, its operation is integrated into the scooter's normal functions. There are no direct user controls on the mainboard itself.

• Power Management: Regulates power distribution from the battery to the motor and other electronic components.
• Motor Control: Interprets user input (throttle, brakes) and controls the scooter's motor speed and direction.
• Sensor Integration: Processes data from various sensors (e.g., speed, battery level) to ensure smooth and safe operation.
• Communication: Facilitates communication between the scooter's display, battery management system, and other smart features.

Ensure your scooter's battery is adequately charged and all other components are in good working order for optimal performance of the mainboard controller.

5. Maintenance

Proper maintenance of your scooter, including its electronic components, can extend its lifespan and ensure reliable performance.

5.1 General Care

• Keep Dry: Avoid exposing the scooter to water or excessive moisture, as this can damage the internal electronics, including the mainboard.
• Cleanliness: Periodically clean the exterior of your scooter. If the mainboard needs cleaning (only if accessible and safe to do so), use a dry, soft brush or compressed air to remove dust. Do not use liquid cleaners directly on electronic components.
• Avoid Physical Impact: Protect your scooter from drops or strong impacts, which can cause internal damage to the mainboard and other components.
• Temperature Control: Store and operate the scooter within recommended temperature ranges to prevent overheating or cold damage to electronics.

5.2 Inspection

During routine scooter maintenance, visually inspect accessible wiring and connectors for any signs of wear, corrosion, or loose connections. Address any issues promptly.

6. Troubleshooting

If your scooter experiences issues after mainboard replacement, consider the following troubleshooting steps:

6.1 Common Issues and Solutions

• Scooter Not Powering On:
