ohms

[Coastal Cowboy]

Thanks as I have had some juices taste on the burnt side. It's a standard battery and no way to adjust the voltage. I guess I may get into that more as I continue on without smoking a cigarette. Now to find a juice I really enjoy so far the best has been dark roast coffee.

Mmm. I love coffee flavors. Which dark roast do you have?

To the point of the OP, Ocelot is right. Your battery comes off of the charger (maybe) firing 4.2v, but it will come down into a 4.0 range fairly quickly, stay there for a few hours, then drop. An eGo battery with no voltage adjustment works great right off of the charger. It's downhill from there.

Variable voltage batteries allow you to increase the output from your battery, but be warned that it can limit both times between the charges and the overall life of your battery.

Spinners and Twists are great. Some of the Five Click VV's can work well too.

We call the "4.2 voltage" e-cigs (that follow battery voltage) 3.7 volt unregulated e-cigs. Which is mostly correct in these cases.

So...........you'd select ohms for the "nominal voltage" of around 3.7/3.6 volts (note how I used a range there so I don't get in trouble again).

Grrrrrr manufacturers that say their un-regulated un-boosted e-cigs are 4.2 volts. Booo! But marketing...whatyagonnado?

Anyway, the 2.5 ish ohms are fine, if not a bit cool. 3.7 x 3.7 / 2.5 = 5.476 watts
2.0 ohms even better. 3.7 x 3.7/ 2.0 = 6.845 watts
1.8 ohms OK too!

Note the solid line. Also note that the high drain we put on these batteries more-or-less shifts the whole curve down a bit. Also varies a bit by battery chemistry so this is a generalization.

It wasn't on purpose

i tend to ignore the whole being in the red zone with my 1.5ohm carts lol fruit flavors just taste so much better to me when im melting my coils

This is a great thread... I learned a bunch. Thanks all for the good info here.

 

[glowplug]

I have been on a sharp learning curve since I started using bcc and trying to figure out what heads to buy. This has been an awesome thread and I thank everyone. I understand more from these three pages than I have from pages and pages of research in the past two months. Maybe it is "when the student is ready, the teacher will appear", I don't know, but I think I've got it! Thanks again to everyone!

Ocelot, I love your ocelot kit pictures and captions. Please don't stop!

BTW, what is a Caterpillar Wrangler? Is it the big yellow machines or the little fuzzy critters or something else altogether?

I believe I am still confused. I have lived in the state of Confusion for quite some time so it is my comfort zone.

I'm not familiar with MyStart, but I looked around a bit and it seems they make copies of other devices. I would guess that the battery is unregulated. A regulated battery is more expensive to make and most knockoffs don't bother. Some do, but not all. It's a guess, but without knowing the quality of MyStart... well, I tend to not give clone makers the benefit of the doubt. There's really no reason to believe it's not a decent battery, though, but if I'm going to guess if it's regulated or unregulated, I'm going to guess unregulated.

I guess I should explain regulated and unregulated batteries. Basically, a regulated battery will give off the same voltage when it's fresh off the charger to the time it runs out of power. Once it can't put out the volts it's supposed to, it "dies." An unregulated battery will give off more volts when fully charged, but will slowly drop off the volts it's giving out as the power drains until it can no longer function and will have to be recharged.

I have seen 4.2 volts as the "actual" upper end voltage for other batteries rated for 3.7 volts. This also leads me to believe your battery is unregulated and probably a 3.7 volt battery.

This isn't really a problem. You just need to be a bit careful to not burn up your coils when it's fresh off the charger. You're getting close to that happening with the 1.8Ω coils but are probably fine if you haven't had issues yet. Still, it's something to keep in mind. Make sure not to hold the button too long for a while once it's off the charger. How long is tough to say as it will depend on how much you use it, but at least a couple hours if your a heavy vaper and longer if you're not.

If you get the 2.5Ω coils you won't have to worry about that... so I guess to make it simpler, just get the 2.5Ω coils and vape away!

Hope that answers all your questions.

My Start more then likely is a knockoff battery. I knew nothing at all about e cigs until a little over 3 weeks ago when I went to ECig Charleston and purchased their starter kit, The girl did ask me if I smoked a lot and I told her almost two packs a day so she suggested the 1300 mah battery. I will say this the battery last well over a day and I do a lot of vaping. I did some reading on the EVOD tank and it had good reviews but nothing said about ohms except it comes in 1,8 and 2.5.

My local store does sell a battery called the Revolver which you can set the volts, but being new I had no idea as to why I woild want to change the volts. Now I'm finally getting it and this forum is very helpful. Right now I have 5 1.8 ohm coils left as I purchased a package of them. I just might order the 2.5's and give it try and see if there is a difference in taste.

Is there less vapor and TH on the 2.5 ohm coils?

Thank you all

Actually, Mr. Ohm's law is I=V/R.
When we include power, it incorporates James Watt's contribution.

Technically, yes. Will you really notice a difference? It's one of those YMMV things.

If your fresh battery is firing at 4.2 volts, you're in the danger zone for coil burnout if you over vape with it. At 2.5Ω you're clear with that particular battery. Hence why I would use them over the 1.8Ω coils.

If you do decide to go with a variable voltage, you'll probably actually want to go with a higher resistance than 2.5Ω. It really depends on how high the voltage can be set on the battery you will get, but if it's an eGo type like your other one, then it's probably a 3.3-4.8 voltage battery. I can't say for sure, though, without seeing the specs of the battery your supplier is carrying. If it is an eGo type VV, you'll want 3.0Ω coils for it. That will let you use the full range of the available voltage settings without worry.

This is all assuming that you're talking about a VV battery and not a device! If it needs a separate battery to function it's a device and some of them (often called "mods") can operate at much, much higher voltage. Mods are a whole different ballgame and you'll have a lot of reading in the mod forum to make sure you are using it safely. If it's just the battery, though, it likely tops out at 4.8 volts and some 3.0Ω coils should keep you safe and vaping happy!

Hopefully, I've explained that well enough for you to understand without scaring you too much.

With my EVOD tank I can only use 1.8 or 2.5 ohm replacement coils. I just now ordered some 2.5 ohm coils and sure will give them a try. I'm still a bit confused with the VV batteries. Is there a specific reason to change the voltage? IE why use 4.2 rather then 3.8? I'm guessing it may have something to do with the ohms or taste of the juice. I'm learning... So use to saying a pack of Marlboro lights.

You can get several different resistance ratings for Evod coil heads.

Kanger eVod/Protank Coil Replacement **5 pack - 2.2 ohms

The 2.2 version is pretty much the sweet spot for me on unregulated batteries like the stock eGo.

Now, for mini eGo 650 batteries I prefer 1.8's and for my variable voltage sticks, I can go days at 2.5. It's all about preference and combinations of equipment.

I dont know why but every time i say or read "ohms" i think of this.....

Heat.

If you go back to my first post, I explain how the electricity through the coil causes friction which results in heating the coil. This is what vaporizes the juice. A higher voltage will create more friction and thus, more heat. If the ohm rating for a coil is too low for the amount of electricity going through it, it will get too hot and, like a light bulb, burn out or pop.

This can be a safety issue and why you always want to make sure to not push too much current through a coil by setting the voltage too high and why you want a high enough resistance coil. A higher ohm coil will simply not allow the electricity through, and in that way, will produce less friction/heat. Basically, the higher resistance coil will simply not allow you to push too much current through it.

How hot you are heating the juices will affect taste. It's just like with food. A particular food will taste different when it is hot than when it is cold. Variable Voltage allows you to dial in the temperature of the juice so that you can adjust the taste to your preference.

For instance, you might find that a particular juice has a cocoa taste to it that gets really bitter at higher temperatures, but mellows out into a really nice creamy chocolate at lower temperatures. On the other hand, you might find a juice that has a vanilla flavour that simply disappears at lower temperatures and to really taste it, you have to dial up the volts.

It all comes down to getting the best taste out of your juice and your personal preferences.

Thank you for the link. I was sure there were only the 1.8 and 2.5
