I like the Joye 302 attys. Haven't tried it on their battery though. The attys are nice though. I would assume it is good. Is this an auto or manual battery? I wouldn't do auto battery on anything. IMO
I agree, I use these attys on my 5v pass
through and they are true work horses imo. I just had my first one die @ about 3 months use. I vaped about 4 or so hours a day on the pass
through.
They seem to be tough, good vapor production, and great flavor. The only negative I have is they don't give quite as good th as a 510 for me. I don't have any experience with them at 3.7v though.
