During peak farming seasons, frequent battery plugging and unplugging will cause connector wear and oxidation. High summer temperatures increase the risk of overheating. Regularly inspect, clean, and maintain battery connectors to prevent flight damages. Please replace connectors immediately if you notice any signs of melting, ensure stable flight and safety.

Professional cleaning and maintenance steps ：

1. First, prepare the necessary tools : 75% or 95% alcohol, wooden sticks, tweezers, cotton swabs, lint-free cloth.

2. Pour alcohol into a cup. Dip a cotton swab and clean each copper plate on the battery plug until the black stains are removed.

3. After using the cotton swab, further clean with lint-free cloth. Soak the cloth in alcohol, then use a flat wooden stick to insert the cloth into the gaps between the copper plates, as shown in the pictures.

4. After completing the above steps, check and ensure each copper plate and gap is thoroughly cleaned.

(Note: make sure plug is dry completely before reconnecting the battery.)

5. To maintain the battery's plug : soak a cleaning cloth in alcohol. Use the wooden stick to insert the cloth into the gaps and clean each one, Repeat this process until it's clean.As shown in the picture.

6. Check whether the copper plates on both sides of the socket (as picture ①) has deformation.If the copper plates are deformed, use tweezers to repair them (as picture ②).

The battery connector is a small part but it is key to ensuring the drone's power supply. Regular cleaning and maintenance can extend its life and ensure flight safety. As a drone pilot, learning about maintenance can keep your drone in the best condition. Let's care for each flight and enjoy a safe, pleasant flying task.
