How new is the site and what battery are you using?

This may well be due to the BMS balancing the battery, entering charge/discharge cycles.

That will be the bms doing that as part of its balancing. Send a snapshot of the cvl/ccl etc charts from vrm.

Min/max cell voltages.

Battery voltage, soc charts also.
