I'm using the ecig from v2cigs with their cartomizer and 4.2v batteries. The fluid I'm using is pina colada from northern vapor 24mg with 70 PG/30 VG. Even with the liquid that came with the kit there was very little vapor. Is this a problem with the battery or cartomizer? I'm assuming fluid I bought is ok since according to most reviews it produces a lot of vapor.
