So basically the amp = battery life? If I run under .5 the battery would barely last?
I'm actually going to write that name down. I'll buy two batteries of either or, and probably go for vtc5 when the company is up and running.
What kind of gauge kanthal are you running? I'm thinking 28-26 gauge being the most common? Use a rig to make your coils, or do you just grab a wrench equaling like 2-4mm in diameter?
No, the amps are the amount of power being pulled out of a battery at one time. Batteries are rated for the amount of amps they can output safely. The AW have a 10 amp rating. The amount of amps your build would pull can be calculated by dividing your voltage by the resistance. A=V/R
So, a 0.6 ohm coil, firing at 4.2v(fresh battery) would pull 7 amps, 4.2/0.6=7
If you try to draw more power than what your battery can safely output, it could vent, get hot, start spewing gasses, catch fire... none of which you want to happen inside a metal tube in your hand, close to your face.
Battery life can roughly be estimated by mah, Commonly 18650's are 1600-2500mah, but there are other considerations there too.
The wire gauge you'll want to use will be determined by what kind of coils you want to build and what your target resistance is, or you can choose your build based on what wire you have.
My personal favorite build is a 1/16" micro coil, using 28g Kanthal, 9 wraps for ~0.9ohms. That's wrapped around a 1/16" drill bit, tight touching coils, wicked with cotton.
