I didn't normally check battery capacity of my past M3SR+, but since I just picked up a refreshed M3LR a couple weeks ago I thought I would run the calculations to see what the battery capacity shows, and track for degradation along ownership every now and then. I've done a few charges, at 75% SOC, and all three calculations come up between 77 - 78kWh. I thought the battery was supposed to be 82kWh. Should it not be close to 82? What am I missing or not understanding?
