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.
