So I'm looking at getting a new mod since my Kanger mini (storm trouper edition) is acting up. I can't get the tank to screw on, and I tried a different Kanger mini tank and same thing. I'm looking at getting the IPV D3. Will be using my Kanger mini tank with it. Anyone have it, and is it a yay or a nay on it? I've had two Kanger mods that have gone bad on me, one being the KBox and the latest the Kanger Mini mod, so I'm staying away from them. I'm looking at getting new batteries to go with it. Mine are about a year old and are Efest 18650's 2500 mah. I'm looking at the LG HG2 INR18650 LiMn 3000mAh Battery - 20 Amp and the AW IMR 18650 3000 mah -20 Amp. Which of the two type of batteries would be the best. I have started building coils and they are anywhere from .79 to .94 ohms and I usually run anywhere from 22 to 28 watts depending on which coil.
