The module is suitable for two or three-rushing 3.7V lithium batteries. Through a short connection settings, two strings are used by default. When the two strings are used, the battery balancing function comes with the module can be used. This is very practical. Enter the Type-C port and welded.When the Type-C port is connected to the fast charge power supply, the charging voltage is automatically adjusted to improve the efficiency. If the welding wire is input, the input voltage should be less than the battery voltage, and the module can only work in the voltage state.

Enter: Optional Type-C port or welded cable input, Type-C access QC fast charging can automatically adjust the charging voltage to improve the charging efficiency. If the welding line is input, the input power supply should be smaller than the battery voltage (battery series*battery voltage)Essence

Output: Support 2 strings and 3 strings. When the battery needs to be added with a protective board, when the default 2 series is changed and 3, a short connection is required, and then the side resistance is removed.2 Strings can use a balanced function, and the two string batteries are in the middle to the BM feet (this equilibrium speed is limited. When used, the two string of batteries should be consistent as much as possible).

Current settings: The green arrow above refers to the two -parallel current setting current setting the current of 100K (0.9A) and 180K (0.5A).Remove or replace the resistance according to your needs.The calculation formula is current = 90000/resistance.

The battery charging is set to the voltage, and the default single series is 4.2V. Generally, the battery is also the value and does not need to be changed.If you need to change, set the board VSET resistor in the control RVSET setting table.

Set the timeout timeout, default no timeout, set the ROT resistance value to set.68K-4 hours, 120k-12 hours, not posted-24 hours

NTC access: Normal use, if necessary, change the NTC resistance resistance value to 82K, NTC welding point and GND access 100K thermistor (B = 4100).

LED indicator: The normal red light is often on, the blue light is on, and the blue light is destroyed after the charging is full.
