Hi Gary. I'm currently using a .21 coil, which draws 17 - 20amps (3.6-4.2v), and is powered by an INR21700T that I got from fogstar.co.uk (highly recommend). It's a 3000mah 35a cell that lasts 1 to 2 bottles before I change it.
While your cell has more mah, and on paper is above the max discharge for your coil, I feel it's a little too close to the max 24a of that cell. It's probably still safe, but I usually like a bigger margin.
I think foggy has even better 21700's, but I don't need any more atm, plus my budget is a bit tight too
