There are tons of new vapers on the forum. Battery Mooch's latest video is compulsory viewing. Mooch is a really mild mannered chap. This is the first time in years that I have seen him really fuming. Whatever you do don't be tempted to buy the WARNING : Imren Gold 15A/30A 3500mAh 18650 If you are new to vaping watch to the end. During the last third he explains the "safe" ratings for 18659 batteries. I would also recommend that you go back and watch his other videos, particularly on battery safety. Never buy batteries which are dodgy. Good batteries are really cheap if you take into account how long they last.
