Hey guys, first post here, I saw other threads talking about this but didn't see any mention the battery getting hot. My vaping style is to drip 3 drops on my atty and pretty much chain puff those 3 till it's done. By the time I'm on like puff 4, the metal around the button area begins heating up (pretty darn hot) and by puff 5-6, the top half of the battery begins getting warm (not as hot as the metal just warm) although the bottom half of the battery stays cool. My vaping specs: black rubber ego c twist 900mah set to ~3.8v and a 2.3ohm atty. I was previously using a 3.5v steady battery and didn't ever notice the battery getting warm, what do you think, is it normal?
