I recently been trying to quit smoking long story short my father in law (good dude) gave me a vape tank and a screw on battery. im new so excuse my newbie terminology anyway the tank is a kangertech mini pro tank 3 and the scew on battery doesn't have a name on it just a logo and a dial at the bottom that goes from 3.3v to 4.8. Just trying to understand what exactly it is i have here. Thanks
