Drone batteries are a key component that affects flight time and performance, so proper use and charging methods are very important to extend battery life and ensure safety. Here are some precautions on drone battery use and charging:

1. DJI Drone Wholesale Battery Use Precautions
Avoid over-discharge:
Most drone batteries are lithium batteries (LiPo), which are very sensitive to over-discharge. Try to avoid completely draining the battery. It is generally recommended to start charging when the battery power drops to **20%-30%**. Complete discharge may cause damage to the battery and reduce its service life.
Avoid overheating:
The battery will heat up during flight, and overheating will affect battery performance and may even cause safety issues. Avoid flying in high temperature environments, especially in hot weather, and try to avoid long-term exposure to sunlight. If the battery becomes overheated, the flight should be suspended and the battery should be cooled before continuing to use it.
Proper storage:
DJI Drone Sale batteries should be stored in a dry, cool place away from direct sunlight and high temperature environments. If the battery is not used for a long time, it is recommended to keep the battery power between **40%-60%** and avoid fully charged or completely discharged storage.
Regular inspection:
Check the appearance of the battery regularly to ensure that there are no cracks, swelling or damage. If the battery is damaged or swollen, stop using it immediately and dispose of it appropriately.
Avoid humid environment:
The battery should be kept away from water or humid environment. Moisture may cause the battery to short circuit or damage. Try to avoid exposing the battery to water during storage.

2. Notes on battery charging
Use the original charger:
Use the charger provided by the manufacturer for charging, because the original charger can ensure compatibility with the battery and avoid damage caused by voltage mismatch.
Environmental conditions during charging:
The charging environment should be kept dry and the temperature should be moderate. Avoid charging in extremely cold or hot environments. The ideal charging temperature range is 10°C-30°C (50°F-86°F).
Avoid overcharging:
Try to avoid charging the battery to more than 100%, especially when it is not necessary to fly for a long time. Although modern chargers have overcharge protection mechanisms, keeping them fully charged for a long time may be harmful to the battery.
Do not leave during charging:
It is best to keep monitoring the battery and charging equipment during charging to avoid abnormalities during the charging process of the drone battery (such as overheating, smoking, etc.). If the battery is not used for a long time, it can be stored in a battery storage bag (charging bag) to increase safety.
Avoid excessive fast charging:
Although fast charging can save time, using the fast charging function too frequently may cause battery loss to increase. If it is not an emergency, it is recommended to charge at a normal charging speed to reduce the pressure on the battery.

3. Precautions after charging
Let the battery rest:
After charging, try to give the battery some time to recover, especially if it is charged to 100% for a long time. Do not start flying immediately, especially if the battery overheats.
Do not rely too much on the charger to be continuously connected:
After the battery is charged, try not to connect the battery to the charger for a long time to avoid burdening the battery with continuous power supply. Try to unplug the charger and use the battery.

4. Battery life cycle management
Battery life:
Lithium batteries generally have 300-500 charge and discharge cycles. Each charge and discharge consumes a portion of the battery life. Over time, the battery's flight time and performance will gradually decrease.
Signs of shortened battery life:
If you find that the flight time is significantly reduced after the battery is fully charged, or the battery is abnormally hot or swollen during charging, it means that the battery health may have declined and needs to be replaced.
Replace the battery in time:
If the battery has been charged and discharged for about 500 times, or its capacity has dropped significantly, it is recommended to consider replacing the battery to ensure the safety and flight time of the drone.

5. Notes on battery storage
When the battery is not used for a long time:
If you plan not to use the drone for a long time, it is recommended to keep the battery power at about 40%-60% and place it in a cool and dry place. Avoid storage in an environment with too high or too low temperatures.
Special storage bag:
Use a LiPo battery storage bag for storage to prevent the battery from shorting or catching fire. LiPo batteries are dangerous to a certain extent. If problems occur during charging, the storage bag can reduce the risk.

Summary:
Proper use and maintenance of drone batteries are essential to ensure flight safety, extend battery life and improve performance. The main precautions include avoiding over-discharge and overheating, using the original charger, avoiding overcharging, regularly checking the battery condition, and storing the battery properly. By following these charging and usage guidelines, you can maximize the life of the battery and ensure the stability and safety of the drone when flying.
