I think I just answered my own question. The MVP 2 has 510 threading... which is compatible with tanks that have 510 threading. The T3s has eGo threading. I'm not entirely what the different is, but there is a difference between the two. I'm pretty sure this is why the vent holes are being covered up by the threads of the MVP 2 and not from my other battery.
So I have a new question. What clearamizers are there that I can get at a decent price (10 to 20 bucks) that use 510 threading?
