Maybe Tesla's new "Megapack" fits into the puzzle as well?

We just published an article on the Tesla Pickup Truck and in that article estimated the pickup's battery size at 200 kWh's and its motors at 600 HP (447 kw), for a paltry C rate of only 2.2; much lower than Tesla's sedans.

The Tesla SEMI truck also has a low C rate. Our analysis of the semi truck had four Model 3 motors for a total of 1080 HP (805 kw) and 900-kWh battery, putting the C rate for the SEMI truck at only around 1. Both the pickup truck AND the semi truck have low C rate (power) batteries.

Here's a figure that shows the effect of format size and electrode thickness on cost (ref):
