I'm vaping with a protank 2 and a 1000 mAh kangertech 3.7v passthrough evod. I bought some 50/50 juice from a shop until my online order comes in an there isn't a lot of flavor but there's enough to get some flavor. I like a nice TH and I'm just not getting it with this stuff. I've gone back to my vv battery and running it at 4.8v but I feel like the flavor is lost at that voltage . Do you think it's just a bad batch?
