Thank you. Very useful and informative.

Outstanding information! Everyone with a 2021 or later model needs to watch this video.

I didn’t know my ‘23 MY had the little CATL battery, I’m not even sure battery is correct name for one. It’s only used when the car is asleep. How long does the CATL battery last?

Also a must watch for anyone thinking about switching to a OHMMU battery in pre 2021 model teslas.

Our 2023 M3 will not ever see one

At 1:02 in the video: "So there is no way you can retrofit this to an older car." Is that what you mean? (I didn't watch to the end to see if he changed his mind.)

Sorry, not backwards compatible.
