Heyooooo! I think I see a problem!
What ohm does that coil read out to?
Additionally (almost regardless of the ohms of the coil), that battery is probably not the right battery for your application. That's a low-amp UltraFire (lol, name might be too ironic soon) battery. It's meant for flashlights, NOT for
vaping. You need a high-drain, high-amperage battery, such a Sony VTC4 or a LG HE2/HE4 or a Samsung 25R.
You could be putting yourself in SERIOUS DANGER by trying to use that battery.
