The elephant in the room, that no one said a thing about is: While all the banter about the mAh's and such has gone on, no one is going to vape at 400 watts.

No one is going to need or use 700 Horse Power in their tiny Car, Yet A lot of people want/buy them!

A mod like this with a 4S 1600 Lipo will work great for some one who use's Big Fancy Coils & wants their battery to Last all Day!
My 4S 1300mAH DNA 250c gives batter battery life that a dual 21700 using the same atty :) Biggest issue with this type of mod is USB charging takes along time :(
