Hello I've been cigarette free for a month now. I want to upgrade to a vv battery but I'm getting confused reading everything. My current set up is an ego upgrade battery with a protank 2 mini. My main problem is Im hitting it too often or too hard and I getting a burnt taste it goes away but I hope theres something else I can do. I've checked the voltage on mine and my wifes ego upgrade battery and on both the voltage is 3.7 not matter which mode it is in. Im using 2.5 ohm coils, maybe go lower? Any suggestions would be great.
