Confused About Low Resistance vs Regular Resistance with Varitabe Voltage Batteries

[YanaGirl]

I'm getting so confused about what voltage setting should be used on LR clearomizers. I have several regular Ego batteries plus I have the Ego Twist, Ego Upgrade and recently the Ego-V battery. The question is should I be using my varitable voltage batteries with regular clearomizers and atomizers and only using my regular batteries for the low resistance type clearomizers and atomizers? I've already burnt out one atomizer using my twist as it gets really hot and a couple LR clearomizers as well.

I also have some eGo 6ml KANGER Horizontal Coil Cartomizers. These are 1.8 ohm so should I only be using a regular ego battery with them? I've had a few burn out really fast using my VV batteries.

I love all my VV's but it is really confusing. Thanks for any help you can give me

Power (watts) = voltage squared over resistance. Watts = heat.

You'll probably not want to go any higher than 4 volts for the 1.8 ohm cartos. This'll give you 8.88888(a lot of eights) watts, which is quite a bit, power-wise. I've heard as a rule of thumb that 7-9 watts is the Goldilocks zone, as far as vaping goes, though your mileage may vary. I try to vape at around 7-8 watts, myself. Anything more usually gives me burnt, dry hits.

Assuming a regular eGo battery pumps out about 3.4 volts, then a 1.8 ohm carto would give you 6.4222(a lot of twos) watts.

VV definitely works better with standard resistance, i.e. you get more leeway finding your sweet spot.

Hope this helps.

What he said. I keep forgetting to turn down my voltage on LR devices and find it really nasty past about 3.8-4v.

Low resistance is fine on variable voltage, you just have to remember to keep the voltage a bit lower. The lower the ohms/resistance, the lower voltage you'll want as a general rule. I think most people like LR for standard batteries, because they can only do low voltage and SR for VV because of the greater range.

Thats why I use a kick in my SB - don't have to worry/forget what atomizer/cartomizer/clearomizer I'm using. I set my kick to 8 watts and forget

On a fixed voltage device, you have to use whatever gives you a good vape. Whether its LR, SR, or something in the middle.

You should use SR on VV devices. The wire used on the coils is thicker on SR atty's and cartos, making them more durable. So with SR, your stuff should last longer, and you can turn them up to where you like them.

Of course, like the others have said, you can use LR, just need to use a lower voltage. You will probably pop more coils this way though.

If you have excel or some other spread sheet program, this page has a nice reference chart for watts

Turn it all the way down when you change to a low resistance coil. Crank it a little at a time until you just begin to feel slight warmth. At that point, you are in the sweet spot. With low resistance on a Twist, don't trust the voltage printed around the dial. As you go lower in resistance and higher in voltage it will begin at some point to setback the voltage to prevent over current.

You can buy an inline digital volt meter with 510 threads for around $15 and it will read voltage correctly on your Twist.

As a general rule "lower resistance = lower power needed"... I found this chart online it might help.

Here is something that i go by, which is pretty much the same as what RollandOfGilead but less confusing (for me) this is the chart of the cart/clearo ohms and what is best to vape them at

View attachment 129285

The Triangle system:

One Triangle: This will cause the cart/atomizer/clearo to heat up faster meaning you get more vapor (and throat hit), but you are sacrificing all this for a short life of the cart

Two Triangle's: This is a perfect balance of Cart life and Vapor (with slightly less throat hit)

Three Triangles: Will heat the cart up slower, thus giving you less flavor, less vapor and less throat hit. BUT you get longer life of the cart

Where it says Don't do it: : you could blow the cart, or destroy your battery and do run a safety risk

Thank you for your help. The chart should help me understand a lot better. I have one more question. I don't even know what ohms the SR atomizers are for my Ego-t tank system. Are most SR atomizers and cartos around 2.2 - 2.3 or are they higher?

Oh and about the watts, I don't get that at all. Sorry, I have been only vaping for about 4 or so months, so my level of understanding is pretty low.

 

[collectuer]

All i know for sure is that 4.8 volts on my ego-twist burnt the crap out of my crysrtal LR 1.8-2.0. Iguess I won't do that again and to make matters worse it was the last of my favorite e-juice

 

[chagrin]

I believe the Ego-t atomizers are around 2.2 - 2.3 ohms, but that's a bit low for SR. Everyone has a different answer, but usually SR is around 2.5 or higher. I think Boge cartomizers are 2.0 for LR and 3.0 for SR and I try to keep things around 2 ohms for LR and 3 ohms for SR so it's easier to keep track of.

You are very welcome on the chart, like i said it is something i use as a guide only. When it comes to the difference between SR and LR i have a personal rule of thumb: If i get the slightest hint of a burnt taste I back down to a lower voltage till the that slight burnt taste goes away.

Can i ask what Cart's you are using on the twist? As when i had mine briefly i found a few carts that did have a maximum setting which i will list below. Now even though the twist marks a change of voltage in increments of .2 (3.2, 3.4, 3.6) you can actually get increments of .1 on the ego twist (3.3, 3.4, 3.5) the least confusing way i can describe this as, is to line the marker between the voltages (say between 4.4V and 4.6V, this will force the ego to give you 4.5V)

Fire Bird (or Phoenix): 3.9V no higher
Boge LR: 4.2V
Stardust LR: 4.4V
tanks: (depending on juice) 4.4V / 4.9V
V510: 3.8V

Gosh was I told wrong???? I have a 3.7v KGO (which supposedly comes off the charger at 4V) and am using 1.7 ST carto and 1.5 DC ST cartos. The 1.7 hits me hard - real warm, string TH and FL. 1.5 - nothing to write home abt. Am I ok to use the 1.7? what abt dual coul - should I get higher ohms? Thanks.

 

[RickMc]

1.7 ohm carto should be fine on the KGO. It's about the lowest resistance single coil you can actually use on them with their 2.5 amp limit. The KGO should come off the charger at right around 4.1-4.2 volts and will initially be delivering around 10 watts of heat...it will fairly quickly settle down to 3.7 volts and be putting out about 8-8.5 watts.

 

[RickMc]

Forgot to mention: The reason you aren't getting as much bang with the 1.5 ohm dual coils is that it's really 2 coils, each at 3.0 ohms resistance. Your KGO is delivering (in the long run) 3.7 volts to each coil, which is producing about 4.6 watts of heat. So you're heating two coils with 4.6 watts of power, which is not the same as heating one with double that.

In order to get the same vape from your 1.5ohm dual coil head, you'd need to feed it a lot more voltage. How much voltage it would take to produce the equivalent (or better) vape is beyond my knowedge or experience, but it would likely be 5v+.

Thanks Rick - that make sense - one more ? - since the 1.7 single is hitting a little too much - should I get a 2.0 single (do they even make those). Think I have seen 2.2ohms.....thanks.

 

[RickMc]

They do, and yes...give one a try. FWIW, that's what I use on the KGO: a Boge 2.0 ohm carto.

YanaGirl (or anyone else) if you need more help on SR and LR, i found this video.......even i am sitting here going "oh....NOW i get it all"....Steel Jan comes through again
