Based on my perusal of information about the V2 Cig (especially
this page of their V2 Blog), the V2 is a Kr8 compatible, which means that Bloog Maxx Fusion
batteries may very well work with a V2 charger. [I have to hedge on that a bit, because there are differences between the Bloog and V2
batteries, e.g., the Bloog is a regulated 3.6V, whereas the V2 is purported to be 4.2V (which I take to mean
true 3.7V, which starts at 4.2V fully charged and gradually drops down from there).]
I think quite highly of the Bloog Maxx Fusion and gave it a
glowing review back in February. However, I want to make you aware of a virtually identical brand, which is less expensive: the
Smokeless Image VOLT. I have owned and used - with great enjoyment - both brands interchangeably. Both brands are less expensive than that overpriced, mass-marketed V2.
Somewhat off-topic (since it has nothing to do with compatibility with your current V2 charger), my number one favorite e-cig now is another Kr8-compatible (but different style) model: CigEasy's
Elite 808, which I recently
reviewed. Its 380 mAh battery is higher mAh than any of the above - and
any other skinny e-cig batt - and its 2ml-capacity cartomizers are both higher capacity and IMO even better performing (e.g., vapor and TH) than those excellent Maxx Fusion and VOLT models. You can use V2, Maxx Fusion, and VOLT cartomizers on Elite
batteries, although I usually stick with the Elite cartos. However, Elite batteries need to be charged in the Elite charger.
