Hello, we are having an issue where our cell voltage readings are drifting when discharging. When there is no current, the voltages all read correctly. However, during discharge, we see that cell 5 and cell 1 have lower voltage readings by about 150mV at 5A. Once discharge is ended, the voltages level off again. I have checked that this is reflected in the registers.

 

These are our filter settings:
