I just got a eGo-VV and usually have it set for somewhere inbetween 3.3-4.5V. I don't know if it's the ejuice I'm using or something else but it seems like it burns my throat if I go any higher. Anyone have any suggestions?
the term "voltage" can be little bit misleading. if im using a LR cartomizer, they run (and taste) the best at about 3.7-4.2 volts (depepending on what juice im using). typically fruity flavors taste best just over 4v with a LR cartomizer.
now...if i use a vivi nova or a clearomizer, the same 3.7-4.2 volts can be used on a 2.4ohm clearo. if i had a cartomizer that was 2.4ohm, i would use at least 4.5volts.
5 volts with a 3ohm carto gives VERY close to the same vape as 3.7volts with a 2.0ohm caromizer.
if its burning your throat, you either have a wicking issue (are you using a clearomizer, carto or a tank?) or the voltage is too high. dial it down until it tastes right, then leave it be.
i hope i didnt confuse you more.
