4.8 Ohm Resistance wire..... Am I crazy?

[finnman1]

I, like most, tend to prefer lengthy battery discharge rates to short ones. I also like to vape at around 7.5 Watts.

In order to get the lowest theoretical current on my vamo, I would be using it at the highest voltage setting; which is 6 Volts. I exclusively use one 18350 battery. I do not own nor plan to own any other battery configuration.

In order to use my Vamo at 6 Volts and vape at 7.5 Watts, I would be using a 4.8Ohm resistance coil. I believe the 18350 to not have any issue with low amperage, although I lack any technical data. I assume everyone would like to minimize battery drain, and therefore vape at the highest voltage possible. Why is this not practiced? Is there a super difference in taste with the thinner wire? What am I missing here?

The larger wire seems like a tax to me. What gives? Battery limitations?

becuase theory and practice dont always match up.
most people dont care that they only get 8-10 hours off a battery with a 2 ohm coil. with 4-5 batteries sitting charged i dont really need to make one last 35 hours. at 1.8 ohms i press the button and wham tasty vapor now.

The device also draws more amps to increase voltage. If you were to use a 6v battery your theory would work but since your battery is only 4.2v max the device draws more current from the battery in an effort to reach the 6v setting.

I've been thinking about this myself a bit lately and you would have to measure current from the battery to find if your device is more efficient at one voltage. I think it would be best to use about 3.7v to get your 7.5w but I have no data to back up my theory either.

Very good response Buzzsaw.

This may help, just plug in 2 of the values.

yea i have given this a lot of thought too because at higher ohms and voltage there is supposed to be less amperage so in theory the battery is supposed to last longer, yet no one seems to be accounting for the loss from having to use the booster circuit to get the higher voltage out of a 3.7v battery. 6V just doesnt magically appear from 3.7 v for free

I prefer flavor over battery discharge rate... and I like to vape when vape is yummi... not when I reach some kind of wattage/voltage mark... doubtful statement you got there...

Hello DiNet! Since were correcting each other... doubt·ful /ˈdoutfəl/ - Feeling uncertain about something.

First of all, Champ, I'm not uncertain about my statement, it was made with years of proper social conditioning. I charge you to first understand correct vocabulary usage prior to stirring up the pot, and secondly, I stated "Most people" prefer the longer battery life. In no way was this directed towards you, DiNet. Lmao -- Might wanna focus less on being cool, and more on the basics.

With the boosted mods, wattage will give you a better idea of battery life. Try a 2.0 and a 4.5 ohm atty at 7.5 watts and see what happens. The advantage of having a lower resistance atty is you have room to increase wattage if you choose to. Your 4.8 ohm atty will be maxed out by the device's 6v limit.

Hum, may I chime in on this one.

Oddly enough the guage of the wire actually is what dictates your battery draw. Stick with me on this one....
28 guage wire....48 ohm per inch...if I wrap a 1.5 ohm coil then this would seem to be a good thing...however upon firing my atomizer I notice that the duty cycle or load on the system will drop my battery from 3.9v to 3.21v. So I'm essentally vaping at 3.2v of power driving the coil.
32 Guage wire....1.21 ohm per inch..same wrap 1.5 ohm coil....when I fire the coil the duty cycle on the battery only drops the voltage to 3.5v to run the coil system...quicker critical tempeature reached due to less amperage requirement.
I've found this out from running a mechanical mod, it allows me to see real time loads on the system without a chip regulating the battery power to the device. The higher the guage of wire the higher the amperage requirement to run the system, and typically amperage is what will run out before voltage will. Also most batteries carry a residual charge or static charge at stand still so the real voltage of the battery can't really be determined er go why most chargers read the amps and only monitor the voltage rather then the other way around (also why your alternator on your car is measured in amps not in volts).

Just a thought
