Bq34Z100 changing SOC values

$

Hello,

I'm using the BQ34Z100 with a 4S1P Battery Pack (2,6Ah / 8-13,2V / 1-30A).

There were no problems with the calibration cycle and the golden image file.
But afterwards at the tests I noticed some strange behavior.

Often the state-of-charge changed its value over night from circa 15% to circa 7% (and backwards) without any load.
Also the state-of-charge wasn’t stable. So it varied highly in the range between 5% and 25%.
Is this a normal behavior of this sensor? Maybe the flash settings are not correct. (see attached config file)

Thanks for help.
