Configuration gestionnaire batterie XPERT PRO

voici la réponse du fabricant xpert pro tbs electronics

This question is difficult to answer, because the accuracy of the Expert Pro also depends on the entered capacity in the setup. When the entered capacity is less than the actual capacity, this can have an impact on the SoC accuracy.

As far as I can see, there shouldn’t be anything wrong with the Expert Pro readout. The capacity readouts of the Ancel looks like it is linked mainly to the open circuit voltage of the battery. As you know, the Expert Pro does true compensated Coulomb counting.

So again, very difficult to answer this question exactly.
