Batteries do not have ohms
V4L batteries run at a full 3.7v and that is the highest voltage available in slim ecigs
Slim ecigs can ONLY use standard resistance (ohms) attachments. The V4L cartos are actually at the low end of standard. That is as hot as you should go on a slim battery - the WOW carts.
If you want 5v, if you want low resistance attachments, or anything like that then you need to buy something other than a slim ecig. On top of that, I doubt that the flavor at 5v will be significantly different from using LR on a fat battery model or mod (anything with 450mah+ batteries). People who use mods and high voltage stuff say there is only a slight difference between using LR on a fat battery model or mod for heat, and using high voltage and their necessary higher ohms to make the same heat. But it will be hotter than a slim ecig.
And you are kidding? She says it runs best on a particular mod? GLV is a particular mod - a particular company's big non-cylindrical ecig.
