Hi
I have a YZPower 10A 20S charger Im using to charge a 20S battery made up from LEV40 cells. I want to cut charging at 4.1V per cell, so about 82V. I opened it up, and found 4 different pots. I found instructions somewhere on the web for which one I should adjust, but I can not get it lower than 83V. So far I have used the BMS to cut the charge at 4.12V (I think, cant remember exactly right now), and the cells settles for just under 4.1V. I works OK I guess, but the charger never gets into CV state. Is there any way to fix this issue? Can I change the potmeter to so I can get a wider adjustment range? What are the other 3 pots for?
