Ah right, well then it looks the part, only worry with it so far is that the 510 is Brass... and not the + pin, that actual threading is brass, so would be worried about it lasting with SS atties being screwed on and off, i would not worry about lipo's too much, the Istisck and MVP's and eVic's and eGrip's all have lipos and for the most part have been safe, even your mobile phone uses a lipo...
But for battery life, a dual or tipple 18650 DNA200 will outlast the 1300mAh lipo in the VT200 mod. thats why i built my own. And building your own will cost no more than the VT200 if you have the right tools already, or access to them..
