In the process of external discharge of the protection plate, the two electronic switches in 8205A are not completely equivalent to two mechanical switches, but equivalent to two resistors with very small resistance, which is called the internal resistance of the conduction of 8205A.

Threatening the single cell protection, protect board design is relatively simple, high technical, such as the need to pay attention to the voltage of power battery protection board design platform.

Kurui is a professional China phone battery protection board manufacturer and China phone battery protection board supplier. Our factory which manufactures phone battery protection board.

The company has a powerful research and development team, has the industry's most advanced automatic production equipment and quality control system, so that each battery protection board quality more stable.

Overcharge, overput, which should be changed according to the material of the battery, this seems simple, but to the details, there is experience and knowledge.

Lithium battery protection plate is a series of lithium battery charge and discharge protection; Function: effectively improve the charging effect under the series charging mode, and detect the state of overvoltage, undervoltage, overcurrent, short circuit and overtemperature of each single battery......
