Hi Guys. I was just wondering what is the safest batteries to use for sub ohm coils. I have a bunch of AW IMRs (1600 and 2000 mah) and a couple of AW Protected batteries (The big black flat top ones). The only mechanical mod I have right now is a Silver Bullet. Are the AWs the safest ones to use? Also, is the Silver bullet OK, or should I get another mechanical? I've been checking out the Empire clones and thinking about getting one of those as well. Thanks!
