Description:
The module is suitable for two or three strings of 3.7V lithium batteries, set by short connection, the default 2 strings, when two strings are used, the module available with the battery equalization function, which is very practical, the input available type-c port and solder wire, type-c port connected to fast charging source, automatically adjust the charging voltage, improve efficiency, if the solder wire input, the input voltage should be less than the battery voltage, the module can only work in Boost state.
◆Input: optional type-c port or welded wire input, type-c access QC fast charging can automatically adjust the charging voltage to improve charging efficiency, if welded wire input, the input power should be less than the battery voltage (battery series connection number * battery voltage).
◆ Output: support 2 and 3 strings, the battery needs to add a protection plate, the default 2 strings, change 3 strings, you need to short the short contact point, and then remove the resistance next to. 2 strings when you can use the equalization function, the middle of the two strings of batteries to the BM foot (this equalization speed is limited, when using two strings of batteries or try to ensure that the parameters are the same).
◆ Current setting: The green arrow in the above figure refers to the two parallel current setting current default is 100K (0.9A) and 180K (0.5A). You can remove or replace the resistor according to your needs. The calculation formula is current = 90000 / resistance value.
◆The battery charging voltage as of 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, set the board VSET resistor against the RVSET setting table.
◆Charging timeout time setting, default no timeout time, set ROT resistor value to set. 68K-4 hours, 120K-12 hours, not posted-24 hours.
◆NTC access: not used normally, if needed, the NTC resistor resistance value to 82K, NTC soldering point and next to GND access 100K thermistor (B = 4100).
Note: normal use without too many settings module, just select a good 2 string or 3 string charging as needed. Unless you use special, more familiar with the application.
