Coming back to this thread late, but I did find the information "from the horse's mouth" so to speak. Andrew Wan (AW) states the AW 18490 IMR 1100 mAh battery has a 15 C rating. That works out to 16.5 amps continuous discharge rate.

IMR16340 / IMR14500 / IMR18350 / IMR18490 / IMR18650 / IMR26500 *Part 2*

IMO this ^^^ is accurate. I've not tried mine that high and probably won't, but I've also not tried my VTC4's at 30A and I'm convinced they are good that high.

I've just come across this thread myself. I'm debating on using the 18490 in my Stingray with a .83 ohm genesis coil. Safe? I know that AW IMR 18650's will handle .8 ohms, but I'm interested in what the 18490's can handle ohms wise. I'm not intending to go any lower than that with the 18490, because I'm staying as safe as I can.

Now according to the app on my phone, which I trust, this comes out to be 5.06 amps at 21.253 watts. Seem feasible no?

This calculation is with 4.2 volts at .83 ohms

I have 2 AW 18490s and have used them with my AGA-T at 0.4 ohms. That's around 10A and 40 watts. IMO you're going to be just fine

I know right I'm in my 30's but I still talk like I'm a little high school kid. Some people just never grow up I guess, I'm still the guy sitting at home watching Spongebob Squarepants wile my friends are watching Game of Thrones, lol.

Kinda funny like how some batteries company names have the word "fire" in them.

Where did you get these 20 amp 18500's?

I pick them up from a local vape shop around my house. I tried looking up more info on them but I can't seem to find anywhere where it says they have a 20 amp limit. They sure do put out the power though. Here's a picture of them.

When it comes to 18500 size batteries, I rock the red Sanyo 20A's. There the bomb, 20amp continuos drain. Will blow away a AW 18500.

Who's saying that these are 20 amp batteries? Ask that sales person to document that these are a high drain battery and document the amp rating. I seriously doubt that they can.

These appear to be protected Sanyo 18500 UR18500FK ICR Li-Ion batteries. 18500 Sanyo 1700mAh Li-ion Battery 3.7V

I would not use these in any mod, and certainly would not attempt sub-ohm vaping with them.

Continuous discharge rate for these batteries will be less than 3.5 amps. (These have a 2C rating.) http://www.illumn.com/18500-sanyo-ur18500fk-1700mah.html

This is scarey if your vape shop is selling ICR Li-Ion batteries as high-amp, high-drain batteries.

Wow. Ive certainly noticed in my area atleast theres alot of ignorance in many areas of vaping knowledge at the local vape shops. Our biggest shops owner doesnt even vape. Some businessmen have started shops without knowing the slightest about vaping.
