I have 2x 160Ah Sunlux Lithium batteries. My problem is that the BM-712 always shows 100% before it is fully charged compared to reality and the Sunlux app. What can be the problem? see my attached pictures.

Your bmv is set up differently to the sunlux. The real question is the sunlus also accurate? Does it use a shunt to measure?
What i would suggest is that you set your charged voltage much higher, since it is a lithium battery. What is the bulk/absorption target for the battery? The charged voltage should be quite a bit above float level but not too close to the bulk voltage
@UrbanR you could adjust the BMV setting "Charged Voltage" to 0.2 volt below your chargers bulk / absorp voltage.
