With the caveat that BMS best practices and particularly the algorithms used for state estimation and future state forecasting are VERY active areas of development (e.g. the BMS is not perfect), I basically agree with this.

There are no special "Porsche batteries". The batteries in the Macan follow the same laws of physics as the rest of the universe.
Batteries love hotter temperatures with respect to performance. Their internal resistance drops as temperature increases (higher efficiencies) and they can charge faster without concern for internal failures (lithium plating). So your car will charge like a champ until the cooling system can't...
That turns higher levels of recuperation on/off. With it on, when you are off throttle there will be a slight drag from the motor regen, similar in feel to compression braking on an ICE car.
