This is not the first mod that I have made. I've mad e few 3.7V boxes and a 5v tube mod. This one though is my first VV mod. I'm using the Madvapes VV chip and indicator. It's powered by two 14500 trustfires. Its all in a radio shack 4x2x1 box. I have to say, for something you can put together for about 22bucks this thing is great. I think on my next one I'm gonna use the evercool chip tho.
