SMOKTech E-Pipe Mod
A great looking and simple mod. Uses a 510 threading connection. Works with protected or unprotected 18350 battery which is installed by unscrewing the bottom of the device.
WARNING: If using protected batteries, point the positive side of the battery away from the button. If a protected 18350 is installed with the positive side toward the switch, the nipple on the positive side of the battery may close the circuit, causing the device to fire continuously.
*Does not include batteries.
