PB Dragon is running a sale on 1300mah Vision Variable Voltage Spinners. These are Ego twists made by Vision that are 200mah more then the largest ego twist. The voltage level is printed on the side of the PV rather then on the actual knob itself, which makes reading much easier. These are not knockoffs of the ego twist. They are visions own version of a variable voltage ego style battery. If anything they are an improvement.
These normally sell for $25.00 - $27.00
