The vivi nova has enough poor performance problems that you shouldn't even have to complicate matters with type of shell on a tank, temperature, or humidity. The thing just cannot keep up with a simple carto tank or rba. If it wasn't so cheap, I would probably hear more people complaining about the poor performance.
I agree totally with this statement. I cannot use them on my vmax at all really. I know the Vmax has some pretty powerful peaks in voltage, but if I am using a 2.8 head, and I set the vmax at 3, the juice out of the nova still tastes burnt. About the only battery I have that runs the VVN okay is my twist.
