Just doing a little reading on the provape 1 at 3.7 volt. Right now I use the smokeless image volt batteries, the smaller and the xl which are 3.6. Would I just be buying the same thing I have or what? New to this vaping so just trying to learn more about it. I know the provape is 510 but it has all these safety feature so there has to be more to this than a smokeless image battery right?
