Can someone explain carto's to me on a 5V mod??

[okiedokiesmokie]

I love carto's. I haven't tried atty's because they just seem to require a bit too much more effort than my lazy ... is willing to exert. I don't see myself ever switching from carto's to atty's any time soon, but never say never, right?

Anyway, seeing as to how I'm not an engineer and failed several science and math classes in high school, I am MASSIVELY confuscious about ohms and wattage and mah's. I keep reading through about carto's on the forum but haven't managed to surmise a general rule for them yet. Can anyone explain what ohms are good for the different voltage batts? Specifically looking for what kind of cartos would best serve using a GLV2 5V mod.

As always, I appreciate ALL the information you guys have to offer, my encyclopedic friends )

Happy vaping!

Generally speaking you don't want to use any atomizer or cartomizer rated less than 2.5Ohms on a 5V mod. 5V is already considered "high voltage" and using most low resistance atomizers/cartomizers will draw too much power, give a burnt taste, and probably destroy the atomizer. The dual coil cartomizers can handle 5V because the load is split between the 2 coils, but generally you want "standard resistance" if you are using higher than normal voltage.

Please refer to this chart:

Everyone has their own "sweet spot", for me it's between 6-8 watts. Therefore, using Watt's Law P=V(squared) / R We have

Watts = voltage squared divided by ohms

So ... at 5 volts .. 8 Watts = 25 / _____ ohms
or
____ ohms = 25 volts / 8 watts = 3.125 ohms

So .. my favorite cartomizer at 5 volts is a 3.2 ohm carto.

Now, at 3.7 we calculate

3.7 squared / 8 = 13.69 / 8 = 1.75 ohm carto (in order to get the same vapor production)

Substituting a standard 2.4 ohm carto (common) we have

P = 13.69 / 2.4 = 5.7 watts (better than the factory 510 kits, but still not as much vapor)

Also, if you can identify your ideal wattage (power), look it up on this chart and you can figure out the ideal carto to use:

Uhhhhh .... what was the question

yeah i like the LR carto's on my 3.7V but it gets super hot and I get a burnt taste if I use it on the 5V. I was figuring I probably shouldn't use it on the 5V but wanted confirmation that those aren't good signs. I'm gonna buy some new cartomizers and just wanted to make sure of what I should get. I wasn't sure if standard resistance would work on the 5V, but I'm guessing that's the route I might go. I had bought these KR808D-1 JUMBOCARTOMIZERS and they seem to be working fine. Just wanted confirmation or to see if there was anything better out there. Thanks Thilium for your help (always ;o) )

Like I mentioned above, the dualcoil cartomizers DO work at higher voltage...and they work pretty well at 3.7V too--thats one of my favorite things about them. If I want a thicker/warmer vapor than I'm getting from the dualcoil at 3.7V or on a eGo battery, I can use the same cartomizer at 6V without popping it.

Gosh, I am so far behind you, would anybody here be able to direct me to how to use a multi meter, with respects to our situation?

Easy peasy .. use Volts DC range to measure battery voltage, use Ohms (resistance) range to measure atty or carto, plus these 2 numbers into the formula: power = voltage squared divided by resistance ..

Or, even better, download and print the chart that is linked to the previous post. Measure volts and ohms, and find volts on the left of the bottom chart, ohms across the top of the bottom chart. The chart will give you the watts used by the volt - ohm combo. Ideal, IMHO, is between 6-8 watts.

Does that help?

It's good to a have a voltmeter for troubleshooting--usually to check the resistance of an atomizer. Checking the voltage at the connection is a decent way to check your battery strength, but when placed "under load"--that is to say, when actually in use, the actual voltage will be a bit lower.

That is unless you get a Darwin ( The Darwin ) that constantly tests the resistance of the atomizer and adjusts the voltage to create the amount of power (in Watts) you select. The ProVari ( ProVari Variable Voltage Ecig: Best Variable Voltage E Cig Available! ) also checks the atomizer resistance, so you can change the voltage and do the math to find the wattage.

I'll try to explain how to use the multimeter.

1. set the meter to read 20 dcv
2. place the black prob in the center contact of battery
3. place the red prob on the threaded side wall of battery
4. press the battery button and you will see the voltage of the battery

My 510 batterys read about 3.9 volts


Sorry but this will not work with automatic batterys.

I agree with Thulium's advice. I only use 5 volt and variable volt PV's. The 801 atty's and cartos are really nice at that level. I use MadVapes 801 cartos ($1.49 each) as well as their larger dual coil cartos (510's) and they both do well.

Oh, you had to mention MV's black 801's ... I thought that was my little secret I love those cartos, especially at HV .. monsters!! They meter out at about 3.2 ohms, great for HV vaping. They hold 40+ drops of juice, last a darn long time as long as you give it about 8-10 drops every once in a while. I don't like the black plastic tip that comes with it (too loose), I prefer a driptip on the end. That way, you don't even need to remove the tip to refresh the juice

ohm = restistance
volt = pressure
mAh = milliampere-hour
watt = power
amps = current

The. three most basic units in electricity are voltage (V), current (I, uppercase "i") and resistance (r). Voltage is measured in volts, current is measured in amps and resistance is measured in ohms.

A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size.

Electrical power is measured in watts. In an electrical system power (P) is equal to the voltage multiplied by the current.

I love the soft rubber whistle tips. When they are too loose, I just get a straight pin, heat it over the stove burner and put a couple of extra gooves in the soft rubber where it fits into the carto. Tightens it right up.
