Troy is wrong there (shocking right?), mostly because he is using in vehicle usable capacity instead of the actual cell capacity if I'm not mistaken, you don't measure energy density like that
Gen 1 4680s were 86.5 Wh and 355 Wh/kg, resulting in 243.6 Wh/kg
Now for Gen 2 it gets trickier because we have none of the numbers, just that it's energy density is 10% better, so 268 Wh/kg, but we don't know how they weight changed, everything indicates that the jelly roll is longer, so the cell might actually be heavier
We can try to figure out from Cybertruck. 1320 cells according to my own estimates, maximum drained we saw is 124 kWh, add a 4 kWh buffer and the pack is 128 kWh, or 96,7 Wh per cell, which seem fair, for 268 Wh/kg, means the cell got fatter by a few grams at 362g
Were are splitting hairs at this level of trying to figure out
So it's barely more energy dense (if your numbers are correct) than a Panasonic 2170?
