Product Details

Features:
1. Made of high quality materials, durable and practical
2. Exquisite appearance, beautiful arrangement of components
3. Boost charging efficiency is up to 94%.
4. Adjustable charging timeout protection, with equalization charging
5. The module has multiple protection, output overcurrent, overvoltage, short circuit protection, etc.
Module interface:
Type-c interface: input to connect the cell phone charger and other power supply to the board power supply
VIN: If you don't use Type-c port, you can use this interface to access the positive side of the power supply.
GND: If you don't use Type-c port, you can use this interface to access the negative pole of the power supply.
B+: connect to the positive terminal of the series battery (the protection board is usually identified as P+)
B-: connect to the negative terminal of the series battery (the protection board is usually labeled P-)
BM: This interface is only used for 2 series batteries, connecting the middle of two series batteries to do equalization, can not be used.
BM: This interface is only used for 2 series batteries, connecting to the middle of two series batteries for equalization, it can be used without attention:
Input: optional Type-c port or welding line input, Type-c access QC fast charging can automatically adjust the charging voltage, improve charging efficiency, if welding line input, the input power should be less than the battery voltage (battery series number * battery voltage)
Output: support for 2 series and 3 series, the battery needs to add a protection plate, the default 2 series, change 3 series, need to short the short point, and then remove the side of the resistor. 2 series can be used to equalize the function of the two strings of batteries in the middle of the BM foot (the equalization speed is limited, use the two strings of batteries or try to ensure that the parameters are the same)
Current Settings: The green arrow on the graph refers to the two parallel current settings current default is 100K (0.9A) and 180K (0.5A). According to their own needs to remove or replace the resistor. Calculation formula for the current = 90,000 / resistance value
Battery charging voltage setting, the default single string is 4.2V, the general battery is also this value, no need to change. If you need to change it, just set the board VSET resistor according to the RVSET setting table.
Charge timeout time setting, no timeout time by default, set the ROT resistor value to set. 68K-4 hours, 120K-12 hours, no post-24 hours.
NTC access: Normal not used, if necessary, the NTC resistor resistance value to 82K, NTC welding point and next to the GND access 100K thermistor (B = 4100)
LED indicator: red light is on during charging, blue light is on when charging is full, and blue light is flashing crossly after detecting abnormality. This time to measure the battery voltage is within the appropriate range
