Question about Riva SE....
From what I understand, it comes of the charger at 4.2, but it's listed as a "true" 3.7 device. Does that mean fresh off the charger it's 3.7 underload (even though 4.2 unloaded)? And what does the voltage taper down to 'loaded' before shutting off?

You are correct. Comes off the charger at 4.2 works at 3.7 under load. Steady taper down to 3.2 before shut-off(I believe). It's been posted elsewhere that all newer rivas are now 3.7 under load but I can't verify this as I've moved on to other systems since my Riva days.
All Riva kits (510 and 901) are 3.7V, from start to finish. They are all PWM controlled so that the voltage remains 3.7 at all times. Once the charge of the battery can no longer maintain 3.7V, the unit shuts off.
First hit - 3.7V
Lat hit - 3.7V
So which is it? These last two posts completely contradict each other
Joye ego's are PWM controlled and are 3.4 ish steadily. Interesting if this is PWM controlled at 3.7.
Well, there you have it. Not quite so contradictory. I think spaceballs is saying that the rivas are 3.7 under load just as I was. The fact that they are PWM is news to me. I thought the rivas were unregulated and the voltage was allowed to float but I could be wrong. I do know that my carto fires hotter on a freshly charged riva battery than it does on a battery that is about to start flashing.
That sounds like an unregulated battery to me as well. The contradictory part was tapering vs regulated, but if you noticed it fires less fiercely near the end, well there it is. I was hoping it was 3.7 under load the entire battery span. I guess we can't have it all
Is it noticeably less near the end, and is the lessness quick, meaning once you start to notice it backing off, it's dead very shortly after that? Or does it taper very gradually? Sorry for all the questions, I was about to get a couple.

That is the first time I've heard the Rivas are PWM controlled and shut off under 3.7 volts. I wouldn't think a 650 battery would hold a charge very long if that was true. I haven't bought or researched the Riva battery recently so I don't know about any design changes. Maybe someone has some new data they could share with us.
All of my info is coming from Liberty Flights. I have asked the same question about both the 510 and 901 models, and both times, the answer was "Yes, it is a true 3.7V device."
In my personal experience using both of these units, I have found this to be true. I never get a burned hit when it's fresh off the charger, and apart from the last hit that actually shuts the unit off, I can't tell a difference as it approaches the end of the charge cycle.
In the past, there were Riva models that were unregulated, and then the Riva SE came out, which was regulated. Then, at some point last year, all Rivas were regulated.
*EDIT* I need to get a MM or voltage reader to check this out now.
Y'all are like a steering wheel coming out of my pants....driving me nuts!!

Obviously there is some perception involved concerning the voltage from fresh to cutoff. Unless you have a meter capable of measuring the voltage while the device is under load. Not many people do. My experience with the Riva was that it provided a good hit especially with the Boge lr. 2.0s and the 1.7 resurectors. Hits were great until right near the end. I got real good at saying, "I better change batteries" and shortly there would come the flashing button. Soon I carried two fresh ones of different flavors and always put then on the charger and replaced them with two more each day after about 8 hours of use. Then the (possibly percieved) voltage dropoff became a mute point.
I've since moved on to KGO 1100s and use the same rotation process that worked with the Rivas.
I'll defer to Spaceballs as I've never actually talked to a company rep concerning the voltage of the riva 650 over the range of it's charge. I was only repeating what I've read on ECF from dozens of threads on the subject and what I personally experienced over the last year.

I have not. I took a look at a site that has them for sale and the cartomizer threw me for a loop. it says theyre permanent. o_0

Thanks for the user experiences
Either way, it sounds like the Riva is overall more powerful than the ego, and stays charged and hits good for 90% of it's battery life, which is what I want.

After looking at it a little closer it appears to be similar to the Riva-T which I have. They are both similar to a Ce2 in design except they have a metal jacket with a window over the tank. The Riva-T jacket is semi permanent with a screw on cap whereas the Ego-c has a removable jacket and the cap is a push on instead of threaded. I like the Riva-T and it produces very good flavor.
If the Riva is PWM regulated I think you would have to use a scope with it to check the voltage. I don't think the inline volt meters will not work on a pwm device. There was a thread and a video I saw last year concerning testing them.

I am clueless at this point. I know what the vendor is telling me, and I know what I am perceiving personally, both of which say that the Riva batts that I have are regulated. I have the same experience as you as far as the end of the charge cycle. The last 2 hits before I get a flashing light are muted, but that's it. I can really sense it then, and I can tell that the battery is about 5 seconds from dying. Other than that, there is no variation that I can perceive of the voltage.
Apparently, the Riva started unregulated, then the Riva SE came out, which was regulated. Shortly after that, all the Riva models were regulated. BTW These are all Eastmall Rivas. With the switch over to Smoktech Rivas, I have no idea. Too bad, as I was recommending Rivas left and right, but I can't now, as I don't want people getting mad at me for passing on misinformation.
I will do a search for it, and see what I need. Thanks.
Now where's Morandir? LOL
OK Rivas are NOT regulated. Proof - http://www.e-cigarette-forum.com/forum/liberty-flights/268205-only-riva.html#post5456219
I think where all the confusion comes from is from the statement " True 3.7 volt battery" lots of people think that means it stays at 3.7 volts but I think what it means it is 3.7 underload with a full charge and not like the ego that starts out at 3.4 and stays at that voltage thoughout the vape. By the way most of what vendors call egos do not have the pwm regulation. I know the joye ego is pwm but I don't know about any others.
That's exactly what I thought when I saw "true 3.7V." That really irks me.
I guess all of these 3.7V kits start off around 4.2 and die around 3.6, then.
I think most of them go down to about 3.3 or 3.4 before they shut down.That's exactly what I thought when I saw "true 3.7V." That really irks me.

Wow! So the 3.3V-4.2V is accurate!?
I am picking up a MM tomorrow to check for myself. With my V2 and Elite, I could really perceive the drop off in voltage over the charge, but not on these Rivas (901 and 510).
I may have to pick up a VV Riva or eGo just so I can get a consistent voltage. Really just waiting to see what the Riva Indulgence V4 has to offer once it's released.
Thanks for walking me through this, Txtumbleweed.
