What should be paid attention to when recharging a lithium battery

Lithium battery charging precautions:

★ The ambient temperature range during charging is 0~+45°C;

★ The charging current shall not exceed the specification code current, generally not exceeding 2C;

★ A battery that has bulging, deformation, leakage, or a voltage lower than 2.8V cannot be charged; the temperature of the battery before charging at room temperature must not exceed 40 ° C;

★ The upper limit voltage of charging shall not exceed 4.22V, and the surface temperature of the battery body shall not be higher than 45 °C after charging at room temperature;

★ It is recommended to use a charger that is produced by a regular manufacturer and has a reliable quality. The battery pack recommends a charger with a balanced function.

Lithium battery discharge precautions:

★ The temperature range during discharge is -20~+60°C

★ The discharge current must not exceed the specification mark current

★ A battery that has bulging, deformation, leakage, or voltage difference ≥30mV cannot be discharged.

★ The lower limit voltage of the discharge shall not be lower than 3.0V (single-cell battery). After the large current discharge, the voltage difference of each cell of the battery pack shall not exceed 150mv, and the surface temperature shall not exceed 80°C.

Other precautions for lithium batteries:

★ Non-professionals should not dissect the battery core, otherwise it may cause an internal short circuit.

Inducing gas, fire and other problems;

★ A polymer lithium battery does not theoretically have a flowing electrolyte, but if it leaks into the skin, eyes or other parts of the body, it should be immediately

★ Rinse the electrolyte with clean water and seek medical attention immediately.

★ Under no circumstances should the battery be burned or put into the fire, otherwise it will cause the battery to burn. This is very dangerous and should be absolutely prohibited.

★ Do not soak the battery in liquids, such as fresh water, sea water, beverages (juice coffee, etc.).

Similar to the drone after charging, it will not damage the battery. The problem is that the drone battery is used for maintenance. The flying hands need to have some understanding of the battery to better maintain the drone battery and prevent safety hazards. Extend the life of the drone battery.
