If the voltage is too low, it can seriously affect not only the vapour but the flavour too. I find that anything less than 3.7v is not even to get LR's going.. Standard eGo batteries, for example, only output 3.2v "under load".. and for me, that is just not enough to get a good flavour.
So in order to increase the vapor and flavor, i need higher voltage battery and LR artty? That means i have to change my PV. Are there any PV to recommend that produce lots of vapor and taste?
