i had this problem when i first used an 18490 aw imr high drain battery 3.7V 1100mah, it won't fire the atomizer and the battery will heat up. i have to remove the battery. I'm using a twisted coil rebuildable atomizer at 0.7 ohms. oh and i'm using an avenger mod e cig. a mech. idk how to fix this. is it because my ohms is to low?
