Those are most likely re-wrapped generic batteries. Who knows who makes them for Smoktech?
Not recommended. Seen at Amazon & EBay at cheap prices or thrown in for free in a kit when you purchase a mod from China. These are
unknown batteries of
unknown quality by an
unknown manufacturer, and not worth the risk using in your mod. Never assume because they were included with your mod that they are safe or the correct battery to use.
Personally, I don't recommend using any battery that you don't know what it is or who made it. Your batteries are the most important part of your vaping setup, don't skimp on their price for your own and other's safety.
