So what do we have here? It seems this popular cheap device takes 3 x AA batteries. Now my take is - This mod combines the 1.5 volt batteries bringing the voltage to 4.5v allowing you to vape off it. For the price I think its a neat little item. AA batteries are cheap, and you can also use the rechargeable.
This is new ground for vaping - my experience with AA battery safety and vaping is almost non-existent.
Please be careful using a mod like this.
