I have so many questions! I got the 4pack ultrafire 16340 batts with the T1 charger thing from battery junction and was wondering, how long do your batteries last? My little chuck always has a burnt taste unless I drip directly on the atty and puff without a cart. I usually use blank carts that I fill with eliquid, but liquid burns off quickly and the throat hit is really harsh, no in a good way as I am usually looking for a throat hit(I use 18mg in the am and then 11mg the rest of the day) I cant tell what the issue is as the vapor seems to get weak within an hour of using(despite multiple top offs) and the crackle of the atty fades quickly. Is it the batteries? The charger? The atty? Or do I need hv juice(ordered a few samples) Anyone run into this? I have heard great things about chucks and little chucks but so far things arent going so well so I must be going wrong somewhere. Thanks in advance all
