When charging the rechargeable lithium polymer battery, be sure to use a dedicated lithium battery charger. In particular, pay attention to the parameters of the battery used. It must be consistent. When the lithium battery is used in combination, be sure to add a PCB protection board to the battery pack. It is possible to avoid the electric core package, leakage, and even fire and explosion, and prolong the service life of the battery as long as possible, but it does not charge and increase the number of cycles of the battery.

At present, lithium charging is mainly a voltage limiting current limiting method. The initial constant current (CC) charging has the strongest battery receiving capacity. As the charging process continues, the polarization is strengthened, the temperature rise is intensified, and the voltage rises. When the charging reaches about 70. At ~80%, the voltage reaches the maximum charge limit voltage and is transferred to the constant voltage (CV) charge phase. In the constant voltage phase, there is a turbulent charging, which takes about 30% of the time to charge 10% of the electricity, the current intensity decreases, and the temperature rise does not increase.
