I have a V5 with both an AeroTank and several Protanks and it works very well. Depending on where you ordered your Vamo from you may have a slight gap between the beauty ring and the bottom of the tank, which is good for Protanks but not so much for the AeroTank. I can't speak for the new Mega but the Aspire Nautilus is a better fit and a better tank all around fwiw. With the 1.5 ohm dual coils you'll be good vaping around 8-8.5 watts or 4 volts. Start low and move up until you get the desired flavor/vapor/temperature with no burning.
