Actually, there was no more tightness with the battery once I got the dent out. The battery slides in and out of the tube freely. The dent was on the threads on the top part of the tube, where it connects to the lower half of the tube, luckily those threads are external so it was easy to get the dent out and file the threads smooth. I just didn't like having to do that. I was and still am in a situation where money was tight, so I appreciated being given the mod but it definitely got dropped hard at some point. The battery charger I was given was also busted up. I tested it for shorts and it checked out so I used it, but only once and I did not leave it unattended and I pulled the battery as soon as the green light came on. I had already ordered an xtar travel charger so I was fortunate to only have to use that busted up charger once. It was one of those generic Chinese chargers with no protection circuit. Even if it hadn't been busted up I wouldn't have kept using it. I have too much going on in my life to be sitting around waiting for batteries to charge to make sure I take them out as soon as they are done charging. The xtar travel charger is excellent and I can charge batteries over night if I want to but lately I have been rotating batteries so when I take one out, I put it on the charger and vape with the other battery the rest of the night. I usually take the battery that's been charging off before I go to bed, but then I just throw the other one on when I wake up. Pretty soon I shouldn't need to rotate batteries. I do it with a mech for obvious reasons, but I'm getting a regulated device soon in fact it will probably be going out to me today. I also bought an LG HE2 to go with it, 20A 2500mah so the way I vape it should last me all day and if not its a pass through so I should be OK.
