Riva 510

[Mork]

I am wanting to buy a better system than my current 510T.

I am looking at the Riva 510 from Liberty Flights and am a bit confused with he description of the battery voltage.
I claims 3.3 to 4.2 volt (Most EGO types are listed at 3.7 volt)
It is not a VV system so the range of voltage seems odd to me.
I was under the impression that Li Io batteries delivered a fairly consistent voltage.

The reason it has me confused is I am trying ti figure out what ohm atomizer I want to use with it. I mean I plan to try out different resistances anyway but if the voltage varies too much then The resulting wattage will also fluctuate thus changing the taste and or vapor production.

Does anyone have any experience with this product or should I just go with a EGO system?

A 4.2 volt Li-ion battery is 4.2 volts full charge with nothing drawing power from it (unloaded voltage).
As it discharges the unloaded voltage will decrease until it reaches about 3.0 volts.
Follow?
Under a load (an atty attached) the full charge voltage will drop. Bigger load, bigger drop.
A full charge cell with a 3 ohm atty might be 3.8 volts fully charged and about 3.6 volts with a 1.7 ohm atty.
Follow?
As the cell voltage decreases the loaded voltage also drops. It drops faster with a heavy load.
Voltage will hang around 3.7 volts for a while but will go down to about 2.5 volts eventually..
Follow
The average voltage of the Li-ion cell over the entire discharge cycle will be close to 3.7 volts.
The average is what the cell delivers, not the 4.2 peak fully charged unloaded voltage.
That's why they are commonly referred to as 3,7 volt batteries.
Follow?
When you start vaping on an unregulated e-cig, like the Riva, the vaping voltage (loaded voltage) starts at about 3.8 but gets weaker as you vape until you are vaping at 3 volts or less. Time to recharge. The cell inside the same size Riva and eGo is the same cell. You get about the same amount of energy out of both.
Follow?

The eGo has a Pulse Width Modulated regulator that takes the cell voltage and pulses it to give you a 3.4 volt effective vape at full charge, and about the same 3.4 volt vape just before it cuts off.
Follow?
So, which is better? A vape that starts out hitting harder, gradually decrease to ego level, then a little less than eGo level,
or an eGo that hits about 'medium' and flat through the whole charge?
To complicate this, the VV eGo has a low range (weak), a medium range (just like the regular eGo) and a high range no regulation just like the Riva).
Your choice. Both have some issues with Low Resistance attys and cartos around 1.5 ohms. That's a pretty big load for the electronics in them. 1.7 ohms to 2.4 ohms is fine on them.

I think I follow quite well thank you.
I am leaning toward the EGO now due to the consistent voltage. I feel it will be easier to "dial in" my flavors by trying different atomizers to adjust wattage at the heat element.
I think I will get a EGO 900 mAh VV pass-thru battery and say 1.8, 2.0, 2.2 and 2.4 ohm atomizers
This should give me fairly consistent voltage especially when it is plugged in correct?
So 3 different voltages x 4 different resistances = 12 different heat settings correct?
And the larger capacity should make it hold a higher voltage longer before it drops to a point that it would change the taste and or vapor production right?

You pretty much got it.

Since the VVeGo is regulated, the voltage will always remain consistent. If you set it to 3.3V, it will stay at 3.3V until the battery charge dissipates completely.

The only difference you will see between the different voltages will be the life of the charge. If you use the battery at 3.3V, it will last much longer than if you were using it at 4.2V for the whole charge. More power = faster battery drain.
