Yeah.Dr. Scott Walker does excellent work analyzing the Optimus bot actuators and electricals, but he's made an incorrect assumption that Optimus bot will use 2170 battery cells, saying it will have over 200 of them. This is contrary to what Tesla showed us in its 'see-thru' diagram of Optimus, which clearly had 4 rows of 7 cells each (nominally a 14S-2P battery: (see details mid-right here)
Slide says 2.3kWh. 2170 cells are 17.3Wh, so it would require roughly 133 of them or 14s10p ish.
28 cells would mean each cell in the slide was 82 Wh which lines up with 4680s at 86Wh each.
18650s would be in the 200 range...
