Battery discharge warning hasnt actually returned, so hopefully it was an 1 off. On the brightside everything seems to be working as it should for now.
As you can see, the voltage drops to a concerning level. while the car is accelerating or cruise control on, this is why i am worried.

Probably all good. Again the battery is charged (assuming below 80% isch, or else not) when the system judge the occasion right, coasting, down etc. Check the posted documents, its all there.
If you measure after fully charged with external charger, you'll see the voltage go down on low 12v as again the system is designed to keep it between 70-80% charged.
