I am having a terrible time getting my vapes to taste good. I am using a Kanger pro tank 2 mini. The coils are 2.5 ohm and the battery is an EVOD. I also have a Kanger T3S and ego battery. Here's what I'm running into: With the T3S and the ego battery I was having pretty good vapes. I changed to the EVOD battery and vapes started to taste worse. I also did not like the "drag" on the T3S, I thought it was too airy. I stopped up one of the air holes and liked the taste and the inhale better. The vape seemed to be consistent between the ego and the evod battery. After getting the 2 mini I was having a bad taste again. I tried the same fix by stopping up one of the air holes. It helped but did not fix the issue. It seems that the EVOD battery is even worse. I have returned everything to factory conditions and still have the burned taste issue. I have tried different coils, (all were 2.5 ohm coils) rotating the batteries between the two, charging the batteries to full charge, taking out one or both of the flavor wicks (destroying two coils in the process) and nothing seems to work. I have also tried different liquids varying from 100% VG to 100% PG, dry burning, priming the wick, etc. Nothing seems to work. I have been told everything from go to 1.8 ohm coils to just get a VV battery. My question is: In your opinion what is the issue and how should I go about fixing it? To my understanding a ego battery is 3.2 volts unregulated and a EVOD battery is 3.7 volts regulated. Is this correct? Between the two, would that eliminate the possibility of needing a VV battery? Thanks in advance for all your help.
