    Sorry I don't have the link. Buy I remember from the presentation Musk saying 400 kwh/kg in 3 years time which was the threshold for aviation. Which would be like having a P100D battery pack for 551lbs in terms of the cells alone.

    I feel Elon had to sand bag for the Osborn effect on time frame and to start under promising and over delivering. But unless Cybertruck and the semi are going to be delayed these cells have to be in the market by around this time next year just in time in terms of dry battery coating process and the anticipated number of revisions of the process going from rev 4 to 7 at a revision per quarter.
