3s are not getting it that we know of. Maybe in the future.wonder how close it is to the lithium batts ohmmu sells.
https://www.ohmmu.com/product-page/12v-lithium-battery-for-tesla-model-3
Why go [lithium]/Ohmmu?
1. Increase reliability
2. Longer lasting (more life)
3. Decrease weight
4. Increase capacity
5. Increase power (no voltage sag, better 12v performance, especially for subwoofers/amplifiers)
6. Less waste (less batteries being used and less material in each battery)
7. Increase efficiency (Ohmmu 12v charges and discharges at a higher efficiency than Lead Acid/OEM)
I’m going to bet these things cost Tesla closer to $50 than to $439...
It has to do with the required high voltage to run the traction. You can't trivially change 400V DC to 12V DC. And you don't want to use 400V for the seat motors.I thought the goal was to eliminate the 12-volt battery and use the main battery. It seems very strange to have a 12-volt battery in an EV regardless of that battery's chemistry.
Thanks for the info. Any idea why would Elon have previously talked about eliminating the 12 V battery? Maybe Elon, being Elon?It has to do with the required high voltage to run the traction. You can't trivially change 400V DC to 12V DC. And you don't want to use 400V for the seat motors.

Daughter's 2019 Kia Niro hybrid has no standalone 12v battery. The main hydrid Li Ion battery has one section set aside for providing 12 volts. It is covered by the 8 year hydrid battery warranty, since it isn't a separate replaceable part. Nice not to have weight or space used by standard battery. Plus for her it will be a 'lifetime battery' on that car.
Further research reveals that while your post is very informative there is a bit more to the story, and the Kia's HV is absurdly small. This isn't quite an apples-to-apples comparison. From the interwebs:
Unfortunate. On my airplane, it used 24 volts and they could get by with thinner wires and associated weight reduction.Tesla/Elon want to go with a 48V system to reduce wire sizes, but there are probably not enough options for auto accessories using 48V at this time. There will probably always be a secondary battery to power the car while the high voltage battery is disconnected. Strange but necessary.

18650. New chemistry but same size as always. Plaid+ will have the latest and greatest 4680Speaking of battery which cells would Model S / X long range be using ? 1860 ? or 2170 ? Also even I guess the plaid variant ? Any idea?
I hope 2170 since at-least that be up to current gen that way.
