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
