Hello everyone,

Below is my circuit for passive balancing Li ion battery pack, I have used differentials opamps to monitor individual cell volatge everything works fine
but my cell voltages fluctuate a lot like around 3.5-3.4V when I turn on my mosfets. Please suggest me if I should add any capacitors or diodes to the circuit to avoid errors and what is its purpose

BAL8,BAL7, BAL6...are my inputs to turn on or off mosfets using Microcontroller and I have used 24ohms resistors as load for discharge
