Product details
The unit is applicable to two or three direct 3.7V lithium batteries. By short circuit setting, default is strings. When strings are used, the module can use its own battery equalization function, which is very practical. Type-C port and soldering wire can be used for input. When the type-c port is connected to the power supply for fast charging, the charging voltage is automatically adjusted to improve efficiency. If the input voltage is lower than the battery voltage when the welding wire is inserted, the module can only work in boost state.
