Please contact me for the chip manual.

The value of Rb is the value of 4 resistors connected in parallel.
The  Balance current is determined by the value of the Rb1- Rb4 resistor. Changing the value of Rb1- Rb4 can change the  Balance current

4.2V(4V2) version : Balance current(A)= 4.2/Rb
3.6V(3V6) version : Balance current(A)= 3.6/Rb
 



A single module can be used for a maximum of 4 batteries (battery packs), using 2 or more modules in series, and can be used for 5-40 batteries (battery packs) in series.
