I can't seem to get the battery heater to come on in the morning. Temperature is around freezing, car is charged for at least an hour immediately before I depart and cabin heated for 15 - 30 minutes, but still I have almost zero Regen on setting off and don't get full regen for 30 minutes driving (so i figure the battery must have been cold enough for battery heater to be worth turning on). Range Mode is definitely off.
