Don't rush to use the lithium-ion battery of your newly purchased drone. Carefully read the battery's specifications and strictly follow the operating instructions.
1. Charging current
Excessive charging current beyond the recommended current can affect charging and discharging performance, mechanical performance, and safety performance.
2. Discharge current
The discharge current must not exceed the battery's specified maximum discharge current. Excessive discharge current will cause a sharp reduction in capacity and lead to overheating and expansion of the battery, which will also significantly reduce the battery's lifespan.
3. Charging temperature
The charging temperature of a drone's lithium-ion battery should be kept between 0℃ and 45℃. Because excessively high ambient temperature during charging can cause the battery temperature to rise, charging should be stopped immediately if an abnormal surface temperature of the battery is detected.
4. Discharge temperature
The lithium-ion battery for drones must be discharged within the operating temperature range specified in the datasheet. When the battery surface temperature exceeds 60°C, the drone should be temporarily shut down until it cools to room temperature.
5. Charging voltage
Charging voltage that is too high, exceeding the recommended voltage, may cause the battery cell to overcharge. Do not underestimate the consequences of overcharging the battery cell; in severe cases, it may even cause an explosion.
6. Over-discharge
Over-discharge can cause catastrophic damage to batteries, so the voltage of a single lithium-ion battery cell should ideally not fall below 3.7V.
7. Storage
Lithium-ion batteries should be stored in a cool, dark place. For long-term storage, it is recommended to fully charge the batteries before storage to maintain their activity and prevent bulging during storage. The ideal storage temperature is 10-25℃, and there should be no corrosive gases at low temperatures.
5. Short circuit
When a drone's lithium-ion battery develops a broken wire after a period of use and needs resoldering, the best approach is to individually seal each battery in a resealable bag and place it in an explosion-proof box. This prevents short circuits caused by bumps and collisions during transport, which could result in the positive and negative terminals of a battery simultaneously coming into contact with other conductive materials. Short circuits in lithium-ion batteries often occur during wire resoldering maintenance and transportation.
