Do the Firefly's have a sealed battery like the Riva's?
Yep. Pretty much all batteries are sealed these days, unless they are automatic. Though, I think we did get a batch a while ago of Riva 901s that weren't sealed.
So now I am confused. Which batts are unregulated?
Smok Tech Riva, Ego, and EM Riva. Joye batteries are all regulated. So is the firefly. Mini batt's will be regulated too. The Joyes are standard 3.4/5, and the LF 510's are 3.6v.
If there unregulated, does that mean you don't have to do a 8 hr. charge before you use them? I perfer a higher wattage.
No. When we say regulated, we are talking about the voltage. A typical 3.7v li-ion cell will fully charge to 4.2v, and deplete around 3.3v. For e-cigs, this means as you use the battery, the voltage, and overall wattage will slowly decrease, until you need to recharge it. Joye/Firefly batteries are regulated, and should produce a consistent 3.4-3.5v, throughout the charge. I prefer unregulated, because I like the extra heat.
Since li-ion batteries do not have a memory effect, long initial charges are unnecessary.
Having both the E-go and the Riva batteries, I have to say, I prefer the Riva batteries, hands down. Better vape with cartomizer or tank, both both pale in comparison to the ease and great results of the cartomizer tank. Talk about a wonderful device - if you like the greatness of a cartomizer, but hate refilling all the time or carrying spare cartomizers, the tank is the way to go.
I second that. I got some new Single Coil cartos for the DCT tanks. these are yummy! They are listed as SCT cartomizers.

Regulated or not, the Rivas perform extremely well. Just for kicks, I went out and got a multimeter to do some very unscientific testing. Here's what I got:
Riva 510 - 4.18V fresh off the charger, 3.431V at end of charge.
Riva 901 - 4.07V fresh, 3.585 at end of charge.
You can see here, that they are NOT regulated. A
regulated battery, would produce a
regular voltage. It wouldn't swing so much. something like this:
3.5v fresh off the charger, 3.4v at the end of charge.
regulating it like that at the low end, allows for maximum capacity. if it were regulated say around 3.8v, it would noticeably reduce use time in between charges.
