It's NON, the 510 connection pin is probably not making good contact. Either adjust the veritas (don't have one, don't know if you can) or take a very small flat-head skill screw driver and gently pry up the pin in the center of the 510.
That is the biggest PITA with MVPs, that 510.Hopefully, they have fixed that with the MVP3. I have a Dovpo DT50, very much like an MVP, huge internal battery, but it goes up to 50 watts and the 510 is a dream to adjust, just a Phillips head.
