Okay so I was messing around I thought I had the wrong pair of batteries because I had one in my dripbox that I thought went in my alien well when I went to change the batteries and close the battery door the atomizer started to smoke without closing the battery door and I did not have my hand on the fire button. But I put the right battery back in and it worked fine . So should I get new batteries or no I have lg 18650 3.7 and 3000 mah running at 50 and all my mods have them in them which all are around 50-60 watt is max I have them on
