Well, if nothing else now i can try the following excuse on my wife, " But babe, I already have these batteries and charger i should get a mod that is made for them! "
Hah, fat chance.
As long as i'm not in danger of hurting the lavatube, I'm still going to use these batteries, but i will be ordering a pair of the right batteries tonight. I too would like to have the option to explore higher voltages, especially since i have some 3.0 ohm cartos and a tank coming in the mail in the next week. I also want to run my lavatube in the most efficient setup possible.
But still, i value the quick input a lot and thanks again for all the replies.
It's hard to go wrong with AW IMR Batteries.

Also, if you haven't, try some 3.0 Boge carts on it....smooth draw, awesome throat hit, warmth and vapor depending on your setting.
