IIRC the 4680 is going to be used in their Texas factory this year.
Panasonic will be supplying Tesla elsewhere.
Tesla is also looking for batteries from LG and Samsung.
Basically they want to double or triple their car production rate in the next couple years.
Yeah. Tesla is making their own special 4680 cells, while Panasonic is making them for anybody who asks and pays nicely 
Basically, Tesla will get all the cells they can get, especially with Giga Texas, Berlin, and a 2nd Giga China probably coming online.
7 watt. You cut plywood with it in a cnc machine? Usually lasers like that have a fan attached on a module
Yeah, and 7W would be so abominably dangerous to handle that I’m not even sure if it could pass regulations.
It would be illegal as a flashlight type pointing device, but no regulation if it’s used like it was intended, like a CNC laser etch and cutting tool. Efficient High Power Diode Lasers | J Tech Photonics
5-10% energy density increase from moving to the new form factor(just Panasonic cells, Tesla cells are different, and have a lot more added to it to give a 50% increase in energy density which make them superior).
Looks good enough to have 4 of them side by side in a flashlight.
A 50% increase in energy “density”? Where did you see that? If true, this new cell can power the MS18 longer than the current battery pack.
That must have come from photo shop somewhere. I thought these batteries were not going to have end plates.
Giving a look inside the new tesla battery pack with these big a*s cells.
Tesla apparently celebrated the manufacture of their millionth 4680 in January, and at least one chinese manufacturer is supposed to be in mass production this year, but I can’t find anything newer than Mar 2021 on that.
Still can’t find any for sale, and I haven’t seen any flashlights to put them in yet, either.
Can anyone mock up a size comparison picture with an 18650?
Imagine the battery compartment of a Q8 reamed out about 1mm. But longer :smiling_imp:
What is that in k1 heads?
π / e
4×18650 would be about 44mm×65mm.
3×21700 would be about 46mm×70mm.
So a sody-pop can light meant for 21700s would be a wider barrel and a bit lest to bore out.
I think James has a strong point. It's fun to conjecture about flashlight applications but the reality is Tesla is scrambling to produce enough for their in house applications. They are hugely delayed in ramping up 4680 packs across their model lines, especially the ever so delayed Semi and Cybertruck. I think outside of the Tesla factory availability will be nil, which renders flashlight applications a moot point. It's fun to dream, though....
Tesla should make a flashlight that plugs into their car like the umbrella in a rolls Royce
....a 1S2P 2x 4680 battery tube for the BLF GT 94X is my dare to dream....
