Generally, a 3.7v lithium battery needs a "protection board" for over-charging&discharging. The battery without a protection board can only be charged with 4.2V voltage, because the ideal full charge voltage of a lithium battery is 4.2v, once the voltage exceeds 4.2v, the battery may be damaged.
The lithium battery protection circuit board is mainly composed of protection IC (overvoltage protection) and MOS tube (overcurrent protection), and is a device used to protect the safety of lithium battery cells.
Prevent the battery from being damaged by excessive current. Important technical parameters of lithium battery protection boards include overcharge protection, over-discharge protection, over-current protection, short-circuit protection, temperature protection, internal resistance, power consumption, etc.
The battery unit is a lithium-ion soft pack battery model AEC653440, rated voltage: 4.2V, rated capacity: 900mAh (from AEC). The battery protection board is responsible for the overcharge, overdischarge, and overcurrent protection of the battery, and has the thermistor to detect the battery temperature.
Multifunctionality In addition to basic overcharge, over-discharge, over-current, and over-temperature protection, future lithium battery protection boards will also integrate more functions, such as power estimation, balanced charging, etc. These features will help improve the efficiency and management of lithium batteries.
Lithium-ion battery protection circuit boards have different circuits and parameters according to different ICs, voltages, etc. The commonly used protection ICs are 8261, DW01+, CS213, GEM5018, etc. Among them, Seiko's 8261 series have better accuracy and of course the price is more expensive. The latter are all produced in Taiwan.
