Just want to say that our Model Y's heat pump design has made a big difference in efficiency for cold weather vs. the battery system behavior in our 2016 Model X. It will be interesting to see how the R1T handles extreme temperature environments and I'll be taking it to both extremes. F-150 Lightning does not have a heat pump system either. Very difficult with those pouch cell arrangements to even consider a lot of focused thermal control, which is why both Tesla and Rivian have said they will not use pouch cells. Too hard to control thermals and expansion. Pouches are easier to manufacture and can get a little better density when you stack a bunch of them into a box.
