Running High Voltage/High Resistance vs Low Voltage/Low Resistance?

[rc10mike]

Ohms law pretty much says there is no free lunch, you dont get free power from nothing.

Running 1.5 ohms at 3.7v is about 10 watts, but running 5v at 2.5 ohms is also about 10 watts.

What are the benefits of this?

Your atty lasts longer if it's a higher ohm- that would be the benefit for me. The LR attys just seem to die early (at least for me)...so I can't wait to get into higher voltage vaping! Of course, this is my theory- please correct me if I'm wrong.

Some like the warmer vape and it does (for me) increase the TH a little. For me I notice in my menthol it is very crisp at LR and more mellow at SR/HR.

The same wattage does not necessarily mean the same quality of vape. There are other factors to consider in this, the surface area of the coil being one of the more significant ones. I've come to like higher resistance (2.5-3 ohms) at slightly higher voltages (usually about 4.5-5 volts under load) more than I do 3.7 volts with LR. In the end, I'm actually vaping less watts, but getting a more satisfactory vape (for my tastes, YMMV). I find the flavor to be better, though a little less on the throat hit, though this does vary depending on the juice I'm using

As for attys lasting longer, that could be true. My SR attys do tend to live longer than my LR ones, but I haven't actively tracked this info so that's just a guess ;-)

also 3.7v with 1.5ohms is 2.46667 amps
5v with 2.5ohms is 2amps this scenario is less demanding on your batteries

interesting posts here!

an additional question:

5v is ok for me, but 6v is a bit of a risk because of the stacked batts???

 

[TennDave]

Stacked batteries is being questioned all over the ECF and w/ exploding tube mods especially.
This is not going to be an issue w/ the Reo VV. If the proper IMR AW or Panasonic battery is used.
1. There is circuitry that protects on all levels- reversed polarity, heat sensing and even shorted atty/carto
2. The Reo has a large vent hole (squonk hole) in the case that a battery just starts to go (very unlikely with IMR).
3. The Reo has a collapsing spring in the case of shorting/over-heating.

The main thing here is NOT TO USE Unprotected batteries (or those that are considered even safer chemistry like the IMR AW). We are finding out that most likely the guy who had the last catastrophe w/ a mod was using regular Lithium (not Lithium-ion or Lithium-manganese) batteries (which are non-rechargeable) when he forgot to take his charger on a trip (bought at Radio Shack). Others w/ similar incidents have also used non-rechargeable batteries that they tried to charge.

The circuitry needed to boost the voltage to 5v will cause total amp draw to be over 2 amps. The boost circuitry needs extra amperage to make the voltage higher.

+1 Tried the 3.7 batts and LR attys/cartos in the beginning and was never totally satisfied so I switch to HV vapin and never looked back Vapin bliss for me

thanks TennDave

but VV reo doesn't boost up the voltage like a provari it steps it down it

The circuitry needed to boost the voltage to 5v will cause total amp draw to be over 2 amps. The boost circuitry needs extra amperage to make the voltage higher.

 

[rc10mike]

Im mainly talking about single cell units like the Provari and using the Kick with the Reo.

So the VV Reo is only made to use 2 cells?

 

[Killjoy1]

Yes, the VV Reo uses the same buck circuit that's in all the Notcigs mods, so it can only be used in a 2 battery setup. Buck circuits are more efficient than boost since they don't strain the batteries as much, as well as being capable of higher safe discharge rates
