I am fairly new to the world of RDA vaping. However, I just received my ohm meter, new batter, and new coils. I have a Big Dripper Clone RDA tank. The coils are supposed to be 1ohm each (I don't wrap my own.) I am using a Kamry K300 battery case and an efest imr 18650 20A high-drain battery. The battery works with my clearomizers so I don't think that's the problem. My ohms read at about .5-.6. Everything seems to be in order to me. However, when I fire the battery, it smokes for a short second and then nothing happens. Is it a short? Did I do my math wrong?
