Even though I initially had reservations about a battery with just 3 voltage settings, when it arrived I was really impressed holding this, as it really is such a handy size for its' capability and decent 1300mAh capacity.
But the Aerotank Mow is still ideal and the same diameter as the Vision Spinner 2 of course!
