Hello, i bought a smok alien starter kit from vapenw.com and well it was great the mod was awesome and so was the tank, then about 2 weeks ago my buddy for some reason accidentally put the batteries on backwards, and put to charge. the vape fried i bought another smok alien, this time from vistavapors.com and well right off the back i noticed that the screen was not as bright as my old one, i also noticed that the charging port on the mod was smooshed in just a lil bit. There wasnt a problem until i put my juice in ( blue raspberry cotton candy). After letting it sit for a while i tried to take a hit at around 40W, and noticed that right away there was a pop from the coil, and juice spit into my mouth. I didnt think much until i hit it about 8 more times, and realized it did the same thing all the time. I have about 90 puffs on it now and theres only been a couple of good hits. Can anybody please explain why this is happening? I have 18650 3000 MAH batteries installed.
