I believe you need the RPM RBA, but keep in mind that I don't believe it comes with a 510 adapter. That means you cant mount it on a ohm reader or mod to build it and you cannot work out hot spots. All you can do is install the coil, wick it, put it in your pod and and hope for the best lol.
However I hear the Mechlyfe clone and maybe other brand clones of the RPM RBA does come with a 510 adapter, but don't quote me on that.
