i know people go high voltage but has anyone done low voltage ? 3v or lower ?

what kind of coil will work best at low voltage say 2.5 to 3 volts ? a .5ohm micro seems like it will work even a simple .6ohm 3wrap could work right ? anyone try this ?

the reason i ask is i have an abundant suply of cr123 batterys and want to use them up lol.

does a single cr123 have the power to drive a decent coil and give a good vape ?

I'm willing to bet you're asking for face melting trying to run a .5ohm coil on a CR123.

Those CR123's would not handle sub ohms. With that said I find that the gauge of kanthal needed to achieve .5 ohms requires more power than 3 volts or less. With 26 or 28 gauge kanthal it would take to long to heat up with such low voltage

your thinking is kind of flawed. although the voltage is lower in your example, there are other factors that are more important when going lower in resistance. a .5Ω at 3 volts pushes quite a lot of power, about 18watts. also what you need to know is the amps, your example is pushing 6 amps which is also quite a bit. compare these numbers to what a normal vv device can run, most every vv device out there will only push 15 watts and about 3 -5 amps. so just because the voltage is low doesn't really matter. when running the numbers from your example you need a quality hi- drain battery not cr 123's ( although I have heard of people doing it)
