Bảng Mạch Bảo Vệ Pin Lithium 4s 12.8v 32650 Chất Lượng Cao

Overcharge voltage range: 3.75±0.05V Overdischarge voltage range: 2.35v±0.05V Quiescent current: less than 30uA Charging voltage: 14.4V-15V Short circuit protection: can be protected, delayed self-recovery. Note: In order to make the equalization effect better and consistent balance, try to use 15V switching source to charge (self Stop current is less than 30mA). Because the equalization current of the equalization IC is about 65mA, and most of the 14.8V iron-lithium chargers on the market will stop automatically when the charging current is lower than 100mA. If there is no equalization, no charge will come in, causing the voltage of each battery to be unbalanced. . Regarding the voltage drop between the battery voltage and the output terminal voltage, this type of protection board works as negative protection. Some of them will have a voltage drop of 0.1-0.3V when they are combined, and the voltage drop will be reduced after several cycles of charging and discharging. ,it `s just normal. The charger should not use 14V power supply as much as possible. A full charge of 4 strings of iron phosphate batteries is 14.4V. 14V power supply will cause insufficient charging, and the protection board will not protect it. It will always be charged. The battery life is affected, thank you for your understanding.
