Did you seriously just compare rates by percentage across different batteries of probably different capacities? Anything to save face for Tesla I guess.
You have 100 of battery X and you go to 1000 of battery X you can charge 10X more watt hours but the same %.
They don't, which is why Tesla announced their plans to build new "Megachargers" https://www.teslarati.com/tesla-semi-megacharger-charging-po...
