Hey Im new here and am still trying to get a handle on the whole vapping thing. Iv been vaping a v2 battery for about 9 months and have tried a lot of different cartomizers and a couple tank systems but have had pretty bad luck so I switched back to analogs for a while. I was wondering if there is a better battery out there and cartomizers that work well. I was thi king about trying out a 510 system any suggestions?
