Cerbo shows the wrong battery level?

Hi all :)

Yesterday I did a load test with my Multiplus 3000 and a 1800W kettle. During the off-season, I set the MPPT to charge the battery around 50% SOC. Before the test, my batteries have been drained to 80% and after the test to 61% (according to the Cerbo GX). Suddenly, shortly after the test, the battery level jumped up to 100%. What happened there?

Setup:

- 2x 200Ah 12.8V Victron Smart Batteries (parallel)

- SmartShunt 500A

- Ve.Bus BMS

- CerboGX

- Multiplus 3000

- 100/50 MPPT Victron Smart Solar

Try a few complete cycles of charging and discharging to see if that improves the calibration.
