A good starter "box" type battery

And black - although most marketing info for the sub nano just shows purple and pink, there is also a black one for pre-order on kangers own site.

I just saw the black one today. Sweet looking with black buttons too. I just got my white Mini and I am loving it. I ordered the silicone case for it to keep the finish looking good. Although my other mods are TC, I wanted the subox for a handy little pocket device for out and about. Works great.
