Also, one thing to keep in mind is that unless I am mistaken the Riva does not actually run at 3.7 volts.
I believe that although it is a 3.7 volt battery it only runs at about 3.2 volts under load.
When I moved up from a 3.2 volt battery to a true 3.7 volt battery I noticed a big difference.
But I don't like 5 volts and definitely don't like 6 volts, too hot for me.
But then I like to take big, long drags.

Just a reminder to everyone that if you're using a button then you already have a control device. At the moment, I'm using a 5V PT with a 2.8 ohm E2 that I've removed the plugs from. I can only hit the button for about one second on a four second draw or else the vape is to hot to suit me. If I change over to my ego battery, I just hold the button about three seconds on a four second draw. Same results, just a difference in the length of time I'm holding the button.
I'd also like to mention that the 5V PT is a good way to check out higher voltage vaping for anyone who doesn't mind dealing with the cord. I have a convinent plug in for it about anywhere in the house, and a adapter for the auto. Saves my batts a ton. The nice thing about the E2 is that I can vape three or four drops at a time around the house, or load it up with twenty or more drops for driving and out and about. Just my $.02.
Later, JD
