Here is a great deal on a 1100mah ego style (not joytech) battery. Everyone should have a few of these as a backup or for your main PV.
HARD COPY: 1100mAh eGo Twist Batteries! Huge long lasting power! It is also great because sometimes you cannot tell how great a juice really is until you hit some higher volts! Voltage goes from 3.2V — 4.8V by simply twisting the end cap. 3 Preset volts are marked for convenience: 3.2V, 4.0V, and 4.8V. Use the presets for quick vaping or set anywhere in between in
increments of 0.1V to customize it for your specific juice or atomizer! WHERE: https://www.gloryvapes.com/
