> Japan's finest batteries

Aren’t all Teslas made in the US supplied with American made batteries? In partnership with Panasonic, for the Model 3, but still a Tesla factory in Nevada. And I think 4680s are all Tesla made, correct?

No, they are all 100% made by Panasonic, with Panasonic technology, in buildings that Panasonic master-leases from Tesla. The only thing Tesla has contributed is the shell and the sign outside. Panasonic developed the 4680 form factor at Tesla's request, by the way that program has been a major failure.

Gigafactory Nevada is jointly operated by Tesla and Panasonic [1]. That's in America. (No clue on the master lease bit. Would be curious for your source.)

		Fun, somewhat related, fact. For a long time (not sure about now), the high-voltage connectors in Tesla were made by (but not labeled) Yazaki. Made in Japan. But the QC tests to Yazaki's deisred level didn't exist yet, and Tesla did their own tests. And Tesla was maximizing it's "Made in the US" stance, which either goes by weight or components. So Yazaki was secretly making unlabeled high-voltage connectors in Japan, selling them to Tesla, who could then test them themselves and claim falsely the source of production.
