I have recently purchased some Panasonic NCR 18650B 3400mah unprotected batteries for my Vamo v3, and WOW!!! They last almost three days of moderate vaping, or two days of semi heavy vaping. They kill my Ulta Fire 3000ish mah batteries. I usually vape in the 8.5-9.0 watt rang, and they are doing me right!
I guess this is more of a review than a blog. But its my blog, so I'll do what I want
I'm definitely picking up the four pack of Panasonic batts from Amazon! As soon as I have some extra money 
I'm sure most of you will know this... but these batteries are unprotected, so don't use them in a mech mod. They (Amazon) sell these in a protected version also. So make sure you know what you need before you spend your hard earned vape money on somthing that may explode in your face.
Vape on, vape often, and no more cancer sticks
