Why are they replacing the 18650's?

I know there are 3 types that can be used in different mods, but 2 are used primarily unless your mod comes with an adapter.

Are these safer? Better dimensions to allow for smaller / slimmer device designs? Capacity seems similar.

Now this is crazy!

I had no idea that the Teslas used 18560 batteries. I know the car has a battery "sheet" that runs the length and width of the car to equally distribute the weight to all 4 corners of the car- which helps in how the car handles and corners.

I knew that the sheet was made of smaller interchangeable cells, so they can be swapped out effeciently from a removal and replacement standpoint, and cost effective solution so 1 giant cell wouldn't have to be replaced all at once.
I always just assumed that they were flat cell batteries, like you see in cell phones.
Turns out they are a special proprietary 18650 Tesla invented with Panasonic, and Panasonic supplies them with.

From what I can tell they run cool at higher loads, last longer than the 18650's, and can be charged under a higher amperage without degrading the battery. It's only a slight improvement but if the market picks it up then that's where vaping will eventually go.

Here's an archived article about 20700's from P Busardo's Taste Your Juice page written by John Muchow: http://www.tasteyourjuice.com/wordpress/archives/14693

EightVape.com is having a clearance sale:

I'm tempted to grab this for $10:

So, having settled in with my Joyetech Primo, I am happy with my selection.
I seriously still can't make up from down in accessing the menu and settings. Full disclosure, I haven't spent more than 10 minutes really trying, and haven't read the user manual. That said, I have never experienced playing with new tech or a device that I had to read the instruction manual to get the lay of the land of the UI & menu settings. They are just that obscure on the primo due to the limited buttons.
It's just not an intuitive interface.

That said, I have ultimately happy because it's primary job is to vape, and using the Cubis rank for mouth to lung vaping is a great and consistent hit. Plus, the frequency that I have needed to swap out for a new coil is much improved. Not exactly sure why?
It still chews through the battery quite a bit faster than my Sigelei, but the spring loaded door and battery tube makes for a faster swap out than the tension contacts and magnetically secured door on the Sigelei.

Huh. What range of Wattage are you vaping in predominantly?

10.5 - 13 watts. 90% it's at 11-11.9.

I have been doing 12 Watts since I got my 1.8 Ohm coils in, before I was doing around 15 on 1.5 Ohm coils. At 12 Watts two 18650's last ridiculously long on my Fuchai. I got through a five day work week without changing batteries. I am tempted to find a cheapo single battery mod because of it.

The next question I have, is how does the change in battery affect the mods' ability to determine battery life? Are mods currently reading charge, or simply calculating usage vs life expectancy? Call me paranoid, but a 18650 discharging is the equivalent of firing a .50 cal round. I don't know what to expect from a new battery at all.

Label me weary.

EDIT: Are they sized differently? They looked to be the same size as 18650s in the pic. If they are formatted to the correct chip then disregard this statement. If they can be plugged in to any current mod (it would be a brave notion to hope to reinvent mods to format a new battery design. It would be like offering a tank that fits who threading rather than 510), then I remove my above statement.

They are apparently slightly larger. The argument I read is that the size increase is really small, but the gain in duration is a pretty good chunk.

Who knows? I would prefer slimmer I think.

I want to get my hands on some of the proprietary Tesla 18650s!

That battery is still around 83% capacity after 3000 cycles!

Damn! I guess we will have to start breaking down batteries on a $/cycle to determine value. With the Tesla name attached, I'm sure it is a pretty penny.

I'm truly not trying to sound facetious, but if it costs less to buy and replace then so be it. That battery life sure is impressive though. Thanks for the info. If you see anything else, please share.

I pulled the pics out of your quote to avoid filling the page but, yeah, that's the stuff I was seeing in reports after I started looking around. I'm a little annoyed at the thought of my hardware going obsolete but I don't know how long this will take to trickle down to vape mods. We might start seeing mods come out with a slightly larger battery sled built in by next year I think. I would imagine that they'll have small adapter pieces built in so you can use both types. I used to see mods regularly that were built to take multiple batteries. Mostly tube mods with additional pieces. I think going 18650/20700 would be easier than that. There is a mod available now that I think I posted about in this thread that takes 18650's and 26650's. The Vaporesso Nebula. It comes with a short rubber sleeve for the 18650. I would think that you could do the same thing with this as long as the spring loaded contacts were long enough.

Also a lot of the chargers would work with both. I use the Efest LUC V4. It's compatible. It is similar to this one shown with an 18650 and a 20700 charging:
