Incidentally:
Google indexes the forum frequently. You can search it like this:
site:
Vapor4Life - E-Cigarette Forum my search terms here
Remembering Google's magic formatting, like + (must include) - (must not include) "[specific phrasing between quotes]", and then the advanced searching stuff, which I leave you to discover on your own...

The forum search doesn't go back all that far, I frequently rely upon Google Site Search.
I am used to that back when yahoo searches were "+chick +robot +donkey" for "robot chick donkey" or you would get any/or.
I just keep mentioning it, and hoping the search will be less limiting here if I mention it more, yet actually "worth using".
The + and - works good on eBay, and pricewatch now too.
FYI: I use regular cartos constantly on the 6v mod. I just let off of the "trigger" for a second every 2 or so while not stopping the mouth inhale, so to speak.
I didn't know about the Tenergy 3.0v when I got my chuck and had 2x 3.7v batts and popped my first carto I popped on the dang-thing (it was working fine at 3.7v WTF was I thinking)?!?!?
Anyone know of a SINGLE 3.7v that fits the Prodigy V2 solid?
(I am not a battery monkey, but becoming one.)
My 18650s for my CHUCK SURELY WILL NOT FIT. hehee
