inferno is not much different from ego, its basically the same. I have 4 of them for my back up in case my 2 of my vv box mods die and I do not have time to fix it. If I were you I'd try different brand cartos. I do not have info on them cuz I drip but I do know there is loads of info on cartos here somewhere. As long is it has a 510 connection, it will work. Also, if the batt don't work, you should be able to replace it free. I had mine replaced. They got a 1 year warranty on batt.
