I want to charge 6S 27Ah LIPO battery pack.
The charge current is 15A. Input voltage is 12V and output voltage is 25.2V.
I am using the same compensation values for ITH and VC with DC2134A eval board.
The thing is, when the battery voltage is low there is no problem i can charge the battery with 15A.
But when the voltage reaches 25.1V charge current became un stable and ripples occuring at the charge current.
So i change the compensation values the circuit works at 25.1 battery voltage but at this compensation values can not work at 22V battery voltage.
I attached the schematics. Hope you can help me.
