[Rumor] new 40700 cell size

A youtube video claimed that it was started by tesmanian.com, but I can’t find anything on there. The exact wording was ’ increase cell diameter to 1.57” ’.

EDIT: found it - Tesla Next-Gen Battery With Maxwell Tech & Patents

On the cooling side, the new cells are supposed to have significantly lower internal resistance due to a new electrode manufacturing process, and so would need less cooling.

There is no talk about abandoning the partnership with Panasonic. If tesla wants to scale up production of the current model 3, new model Y, soon to come semi truck and cyber truck as well as the stationary storage division per plan they need to increase their battery supply by orders of magnitude. Since that kind of supply doesn’t exist, they are attempting to start their own production in addition to what they can source from Panasonic, Samsung SDI, LG chem and CATL.

makes sense, fewer cells, simpler wiring, simpler bms, lower cost. increased reliability,

Oboy. Back to the long, heavy flashlight.
I bet M@g sues over the form factor.

Well, at least it explains Teslas recent insane stock movement where it went from overpriced at $300 a share to EXTREMELY overpriced at $900 a share (currently $741 a share still valuing the company significantly more than Ford and GM). Beyond electric cars, capable scaled up storage batteries could and likely would be used by everyone in the world to store wind and solar power in an attempt to move away from carbon sources.


.

mag will not fit 40mm cell, D tube id is a bit less than 35mm,. boring out is also not an option, due to o ring seats,

Unless we are all moving to 4D Maglites and BLF GT as EDC, this will not survive in our EDC life

I did. :innocent:




our edc’s are safe, 18650\350 are still around

Great, another reason to buy more lights. :person_facepalming:

40700 cell has 3.6x the volume of a 21700 so could have approximately 3.6x4.8Ah=17.3Ah.

If they exist, these cells will not be going to the consumer market. It’s possible, but not guaranteed that other manufacturers will copy the form factor.
So don’t worry for now :wink:

An SP36 with a 40700?! YES PLEASE!!

Which is more than 4*18650 and close to 4*21700.

If this cells shows up, the current pop can lights will quickly become obsolete.

And now we wait until Elon Musk googles to discover this thread, and he’ll be like hey 40700… why not? And this is how we get what we want! :smiley:

Wow I wish this is true. Im imagining the idea of someone manufacturing a light with four of these in series. You can run 10k+ lumens for practically unlimited runtime!

Even the idea of a ROT66, D18, BLF LT1 with USB-C charge and powerbank would be real sweet

My thoughts exactly! :+1: :smiley:

Imagine unscrewing your flashlight and taking an 40700 out of it.
Most of your friends would think you're playing a joke on them :P

Think in the price of those 40700…

50$ each???

then find a cheap charger that can charge 2 or 4 of those simultaniously with like 15A each

Think in the explosion and fire that could occur if something goes wrong with just one of them XD
