You have the capability of vaping in the range of 3.2V to 4.8V on these batteries, something unheard of in a battery this size! It truly doesn't get much better than this. The price on these batteries is significantly lower than similar devices on the market and you don't have to have fancy chargers and batteries to make them work! You charge them up like your standard EGO series batteries and vape away.
You control these via the small dial on the end of the battery. There are small marks on the battery and dial that indicate what voltage point you are set to. These batteries also have the original on-off feature via 5-click setting that allows you to turn the battery off when it's not going to be used for a while.
