If the 4680 and structural battery pack info is correct on web link youi provided, the open structural battery packs on display at Cyber Rodeo last week were for MY-LRs since these had 828 of the 4680 cells. Since it appears these provide just about the same KWH of capacity as the current battery pack in the MY-LRs or MY-Ps, then I doubt any other EPA certification is needed beyond what was already issued for the 2022 MYs.
As I understand it the original "full" design for the 4680 structural pack had 960 cells. What we're seeing in real life is a smaller pack with 828 cells - that lines up almost perfectly with this initial pack running about 70 KHW vs the existing MYLR size of 82 KWH
It looks like the twitter guy is just making up a 690 cell pack - it's the first I've ever heard of it
