• Acceleration: The controller regulates motor speed based on throttle input, providing responsive acceleration.
• Braking: It manages regenerative braking (if applicable) and cuts power to the motor when brakes are applied.
• Power Management: Optimizes power consumption from the battery to the motor for extended range and performance.
• System Integration: Communicates with the scooter's display, lights, and other electronic accessories.

6. Maintenance

Proper maintenance of your controller ensures its longevity and the reliable operation of your electric scooter.

• Keep Dry: Always protect the controller from water and moisture. Water ingress can cause severe damage to electronic components.
• Cleanliness: Periodically inspect the controller and its housing for dirt, dust, or debris. Clean with a dry, soft cloth. Avoid using harsh chemicals or solvents.
• Inspect Connections: Regularly check all wire connections to ensure they are secure and free from corrosion or damage. Loose connections can lead to intermittent performance or component failure.
• Avoid Physical Damage: Protect the controller from impacts or drops. Ensure its mounting is secure to prevent movement during scooter operation.
• Temperature: Operate and store the scooter within recommended temperature ranges to prevent overheating or cold damage to the electronics.

7. Troubleshooting

If you encounter issues with your electric scooter after controller installation, consider the following common troubleshooting steps:

• Scooter Not Powering On:
