By short circuit setting, the default is two strings. When two strings are used, the module can use its own battery equalization function, which is very practical. The type-c port and welding wire can be used for input. When the type-c port is connected to the fast charging power supply, the charging voltage is automatically adjusted to improve efficiency. If the input voltage is less than the battery voltage when the welding wire is input, the module can only work in the boost state.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"font-family:\" open sans roboto arial helvetica sans-serif simsun align=\"start\"\u003e\u003cspan style=\"font-size:20px;font-family:\" times new roman serif\u003e◆ Input: Type-c port or solder wire input can be selected. Type-c connected to QC fast charge can automatically adjust the charging voltage and improve the charging efficiency.

The battery needs to be equipped with a protection board. The default is 2 strings. When changing to 3 strings, short circuit the short contact, and then remove the side resistance. The equalization function can be used when two strings of batteries are connected. The BM pin is connected between two strings of batteries (the equalization speed is limited, and the parameters of two strings of batteries should be consistent as far as possible when using).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"font-family:\" open sans roboto arial helvetica sans-serif simsun align=\"start\"\u003e\u003cspan style=\"font-size:20px;font-family:\" times new roman serif\u003e◆ Current setting: The green arrow in the figure above indicates that the default setting current of two parallel current is 100K (0.9A) and 180K (0.5A).
