Hi Ti,
Just want to find out what the balancing current path is, in my opinion, should be something like:
There should be no current run through RCB1. And I guess the resistor RCB1 and Cin will provide a low pass filter for the balancing chip, however I can measure 0.5V voltage drop across the 260ohm resistor RCB1, don't know what the reason is.
Any comments will be appreciated.
Thanks!
