I'm currently looking into a mod but I started to get a little confused. Right now I'm using a ego 650mah battery with a LR306 atty. What is the difference if I went with a 3.7volt mod (ex. Puresmokers, provari, etc)? Won't it be the same as my ego battery, since the ego runs @ a 3.7volt too? I know with a variable volt mod i would be able to adjust the volts if I'm using a LR/HR attys to my liking. But I guess my question really is there a difference between my ego and a 3.7v mod? And if so what would be the benefits of going with the mod?
