2S 3S Type-C USB BMS 15W 8.4V 12.6V 1.5A Lithium Battery Charging Boost Module With Balanced Support Fast Charge With Indicator

The module is suitable for two or three strings of 3.7V lithium batteries. By shorting the setting, the default is 2 strings. When two strings are used, the battery balance function that comes with the module can be used. This is very practical. The input can be type-c port and soldering When the type-c port is connected to the fast charging source, the charging voltage is automatically adjusted to improve efficiency. If the input voltage is lower than the battery voltage when the welding wire is input, the module can only work in the boost state
