I was surfin' around looking for some new cells and ran across this info. I thought I'd share. Interesting results.

Wow, that's a great article. Excellent information there. One thing to note, the Japanese name brand batts like Panasonic and Samsung are the best ones. They're often packaged with protection circuitry and branded shrink wrap then sold retail by smaller companies like AW so the good ones are not actually coming from a whole bunch of different makers.
Really good info D...I'm pretty new to this whole vaping/modding thing and I have to say a lot of things about this hobby are subjective i.e juice type, atomizing vehicle and voltage at which to do it at however one thing we all have in common is the need for the best power-plant to achieve our own personal vaping nirvana...my head spins over the number of choices out there when it comes to batts (I personally use Trustfires and that's just cause my local guy sells em cheap and I get them in days, not weeks)...now that I have a supply of them and have the luxury of time, it may be time for a re-think
Did I read that chart right for the AW? Looks like the 2600 has a more steady discharge than the AW 2900, stays in the 3.6-3.7 range longer?
The 2900mAh Panasonic battery (supersceded by the 3100mAh battery) uses a proprietary chemistry that actually has a slightly higher internal resistance than the standard LiCo chemistry of the older 2600mAh cell. It holds a little more charge, but also drops a little more voltage internally. The effect increases as charge is depleted. That's why you see more variation in voltage under load. For most applications, like laptops and such, the steeper curve is not an issue since it has zero effect on run time. For an unregulated e-cig, it could be a consideration since lower voltage output means less power output. To put it simply, longer run time, but more battery fade.
Did ya take a good look at the Tenegy2600 (a Chinese cell). Compare that one to the AW2600.
In the RC world Tenergy is well known to re-label other companies products as their own.
So they are sorts like the ultrafire
my post was regarding duration according to the charts.

Thanks for that bit of knowledge, There aren't any vape shops yet where I live but there are a ton of hobby shops for RC planes and cars. I called a few and they had great battery prices.
be weary though, Tenergy has been a sub par company, from my experience, what they cant re-label they attempt to reproduce.
just a heads up.
Obviously AW IMR is leader on complex properties - very stable voltage, excellent load ability, compact. We can use these batteries even without a stabilizer.
Everybody re-labels. You think Redilast, AW, SolarForce, Senbon, Xtar etc make their own cells, or even use the same manufacturer across their entire line?
So you have used the Tenergy2600 Li-Ions?
They have consistently performed well over the years in every test I've seen. Their mAh rating is also right on the money, and their sample to sample variance has been shown to be almost nil.
I didn't realize that 18650s were big with RC.
I thought the RC guys just use the LiPo flat cells. I don't see how they could use any round cell. The drain the motors pull on the batteries can be upwards of 50 Amps, unless they're using round cells for the RF stuff like the handset.
