Got my hands on a Prodigy V3 and this thing is SWEET!!! It takes the AW 17670 3.7 volts 1600mah. The battery should last all day and all night. I love this thing. Dripping is awesome. It's got a drip well so you don't waste any juice too. The atomizer sucks up the juice from the well and you don't waste a drop. This feature is really nice. And the bottom mounted locking switch is awesome as well. It can work at 3.7 or 6 volts. You just have to get the 6 volt kit. If you're looking at these, you can't go wrong with this mod.
