**Original Title: MG-1S Plant Protection Drone Battery Plug Maintenance**
The MG-1S is equipped with XT100-L and XT90-L yellow male and female connectors. The metal parts are made of brass and coated with a gold plating for better conductivity and durability. The outer casing is constructed from high-temperature resistant nylon, ensuring strong mechanical strength and excellent heat resistance. The metal components and the housing are integrated, allowing the plug to handle high current loads effectively.
Although the plug design is robust, some users may still have questions about its use. Today, we’ll walk you through some common concerns and provide practical solutions to keep your MG-1S running smoothly.

**"Lubrication Improves Plugging Smoothness"**
To prevent loosening, the plug is designed to be tightly sealed. This can sometimes make it harder to insert or remove, especially after repeated use. To make the process smoother, you can apply a small amount of lubricant to the plastic housing of the plug. However, it's important to choose the right type of lubricant.
Apply the lubricant to the areas shown in the diagram below:
The lubricant should be non-conductive, chemically stable, and able to withstand both high and low temperatures. While professional-grade lubricants like Dow Corning DC4 are available, they can be quite expensive. A more budget-friendly option is to use solder paste or wax, which provides good lubrication without damaging the connector.

**"Plug High Temperature Alarm Maintenance"**
If your MG-1S starts showing a high temperature alarm on the battery plug, there are two main reasons to consider.
First, frequent plugging and unplugging can cause the banana-shaped metal contacts to wear down over time. As the contact area reduces, resistance increases, leading to overheating. In such cases, you can gently adjust the metal part using a flathead screwdriver to restore the contact surface. Be careful not to apply too much pressure, as this could make the plug difficult to use in the future.
Second, improper insertion or removal might cause sparks, which can lead to oxidation on the metal parts. Oxidation increases electrical resistance, causing the plug to heat up during operation. If you notice blackened or oxidized areas, it’s best to take the unit to an authorized DJI Agricultural service center for a replacement.

**Proper Insertion and Removal Technique**
To avoid damage and ensure safe operation, always hold the plug itself when inserting or removing it. Find the correct point of force and push or pull quickly and smoothly. Avoid twisting or forcing the plug, as this can cause internal damage.
Make sure the plug is fully inserted to ensure proper contact between the internal metal parts. When removing, pull it straight out in one smooth motion. Avoid leaving it partially connected, as this can cause electrical issues or even short circuits.
