Im completely new to vaping, and i purchased the Tesla Invader V1 mod. I had trouble getting the batteries to go in, and ended up snapping off the metal spring plate for one of them. I attempted to tape it back on, but not sure if that fixes it at all or if that battery slot is now broken. I have the aspire nautilus tank on it, i put in two 18650 batteries. The aspire nautilus seams tight trying to suck in the vapor. Ive tried friends and its much much easier to inhale. And when i exhale, the amount of vapor is not great at all. From the videos I've seen on youtube i should be able to produce a great deal more. But I'm not, just small amounts of vapor. Is this because of the battery issue or am I doing something wrong?
