Ya, I didn't think that sounded right.
I've been pretty much full time 6v for the last two weeks.
Its funny how many times I've tried it and didn't like it.
Then I got to where the 5v was doing it for me, but those batts don't last for crap.
I only have two of the AW 3v but they work fine. I have to admit for being such an AW fan I'm doing fine with the 6 Tennergy liFePo4 batts that came with my charger in a kit. And they are 750 mAh vs 500 though I feel like they only last about the same as the AW. Might be a case of AW's rating being correct and Tennergy being a little ambitious with their mAh rating.
Either way the 6v gives me more than twice the vape time over the special 5v batts. And with an IKV 3.5Ω 510 or Boge 3Ω Cartomizer its a sweet sweet vape.
6v is the one voltage where I feel a cartomizer gives just as good of flavor as an atomizer does. Add that to the ease of use and the fact the the 3Ω Boge last 12 days with my juice its making my atomizer budget smaller and my life better.
