The Baphomet stacked mod is designed to be used with either 2x18650 or 2x 20650 (with included 18650 adapter) utising the unique silver plated switch contacts that helps to prevent arcing. 26mm in diameter which the included Unholy V2 RDA sits perfect on. Very limited run with only 500 of each material made. The Baphomet mod is not just a beasty cloud chasing device but also a work of art. 

Please note this is a series mechanical mod, a great understanding of ohms law and battery safety is needed, if you do not have a great understanding of either of those please do not purchase this product.
