Thank you very much!
Q1 mosfet is used for charging... I will measure battery voltage, and with PWM turn on Q1 depending on battery voltage. For example if battery voltage is 11V, Q1 will be on 80% duty cylcle (12V) and charging current will be around 1A
I forgot about that Vgs voltage, and i tested on breadbord only for the first cell.
So, now it is ok? I switch every 2N7002 N-CH mosfet with 15V through NPN transistors. So Vgs voltages are 15V for Q4, cca 11V for Q5 and cca 7V for Q3. That should work now?![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
