Please confirm my battery knowledge

[Greg095]

I am currently running a Nemesis Clone with, Patriot rda and have built a .5ohm dual coil set up, using twisted 32awg Kanthal. I have a MNKE IMR-18650 that I am using in my mod. Based on my calculations using ohms law calculators and from various charts and threads on this wonderful site, I am still above the limits of my battery..... Am I correct in that statement? I am the type of guy that can do my homework, but still need the teacher to grade my test before I am comfortable. Also, is there a better battery that I could be using for my set up?

Assuming your battery's voltage under load is 3.7V, your setup will demand 7.4A. A quick search of your battery pulled up a 20A max continuous current for me. If that is what your battery is rated at, you're safe. You can essentially go down to 0.2 ohms before you reach the limit of your battery, but I don't recommend doing this. Always keep a little bit of wiggle room in case something happens and your battery needs to pulse out a higher current than you calculated.

TL;DR, you should be fine.

If you want a battery that is "basically" build and forget, get a Sony VTC3/4/5 battery. With a 30A continuous discharge rating, you'd have to try and blow these things up.

You gotta use 4.2 v to start at. That is a fully charged battery's voltage.
with a .5 ohm build, that is 8.4 amps. Still OK but quite a difference.
