Apologize if this has been covered already but is there any way I can tell if my Model 3 has the increased 82 battery pack v the 79? My car has an 85xxx vin. I bought it off the lot in early January but it appears that vin range had an early December delivery date. It was available for sale at my local dealer. Looks like not all 2021s got the increase so trying to figure when the cut off was. Thanks.
