So I put in an order Wednesday and I got it today..Wow!!! Supper fast!!! But when I tried to use the battery I can't seem to drag hard enough to get the light to turn on. If I do a supper drag I can get a split second of vapor. When I looked at the battery I noticed the hole in the center is huge, and it has the same slit the carto's have. (not sure how to explain what I am talking about but it is like a path going threw the raised part were the hole is). My vapor king does not have this "path". Is the battery missing a piece like a screw or is this just how they are? As it is it's completely useless. Any help would be great..
