I filled up 5 random e2's v3 and 3 random v3.5. These are new UNMODDED e2's(after a dry burn which i always do regardless).(even if it has no primer i still dry burn it).
I then proceeded to use one at a time on the tek mod(nhaler.com, drew is the freaking man), Depending on which i used at the moment i would need to adjust the voltage and i could replicate the bad taste by going way to high.
but my point is on each an every one i was able to tune the voltage on each one and get it to work perfectly and wick properly by getting the sweet spot.
most of the 510xl's worked at the same volt and one needed a higher voltage, the 808's also varied, some worked perfectly at the same volt that the 510's did, while others needed to be bumped up more to find its sweet spot.
Im pretty positive the e2's have a sweet spot that removes bad tastes and wicking issues.
i dont know the exact voltage since im going by a guide drew gave me so I dont wanna just guess but im willing to check if someone shows me how.
I truly have never been happier vaping. They all work incredibly well at the proper volt, and the vape is just right, not to hot, not cool, just right and huge vapor each and every time.
I'll have to make a video for the tekkmod and e2. I know its pricey and a bit big but im a battery ..... so i love it and i cant reccomend it enough, variable devices are the way to go period.
