An engineering reference that happens to be beautiful.

Why this exists

Tesla doesn't publish a list of which battery is in which car. Owners piece it together from forum threads, registration papers, regulatory filings and teardown videos. The knowledge is out there, but scattered, sometimes contradictory, and hard to verify.

The Atlas brings it together in one structured, navigable place. Each pack has a technical profile. Each vehicle variant links to the packs documented for it. Every number carries its source and an honest evidence level.

What makes it different

• Evidence on every value. Manufacturer-confirmed, documented, community-reported or estimated, shown everywhere a value appears.
• Disagreement stays visible. When sources conflict, every value is shown. We never silently pick one.
• Unknown means unknown. Gaps are labelled, not filled with plausible guesses.
• Honest identification. The finder lists every plausible pack and explains why it can't narrow further.

Credit where it's due

Much of what is known about Model 3 and Model Y pack codes comes from the community, above all the Akkuwiki maintained by members of the TFF Forum (Tesla Fahrer & Freunde). The Atlas uses it as a research reference and cites it wherever it informs a value. Its tables are not reproduced, and our records are structured independently. We are grateful to the owners, teardown engineers and journalists whose work makes a reference like this possible.
