ohm's...mahs....volts....oh my!!

[Hibiscuits]

I'm sooo confused! I do get the mah's, but volts and ohm's are confusing me. Youtube vid tells me I can fry my battery if I am using something with too high ohm's. I don't think I have reached that point. I have the 1000mah eGo upgradee variable volt. So, I'm good for 3.3 to 4.1 I believe it is.

Is there an ohm's for dummies post around here somewhere?? LOL I'm looking at the rebuildable Stardust, but I've no clue what the difference is in the ohm choices. I use high vg juices. I have the non rebuildable 2.5-2.8 ohm short wick Stardust and it's been wonderful for weeks now. Should I just stick with the 2.8 coil head, what will the others offer me?

Here is a safe vaping chart. This is to be used as a guide, not a law. The voltage is at the top of the chart. Since you have a Twist, you'll have some play in that. Along the left side, you'll see the resistance of the carto in ohms. The area in green is what you are looking for. That is the 'desired vaping area'. Hope this helps clear up some of the confusing in your mind. I know I was TOTALLY dumbfounded by this myself when I first started vaping!

Thank you, Kay!! Exactly what I was needing. I searched and searched before I asked and I'm sure I overlooked it several times. Knew someone would be able to point me right where I needed to be

You will find this a great help in understanding all that. (a good thing to bookmark so you can find it easy)
Ohm's Law Calculator

You will find that you enjoy vaping at a particular WATTAGE level. Right now you are vaping at a little under 6 watts in the unregulated mode of your eGo battery.
Once you know what wattage you like, it's easy to figure out how to set up your PV to get there.

That is a very cool chart. I had no idea anyone made a vaping chart.

The lower the resistance (ohms), the more drain it outs on you battery because it draws more amps. Since you are using a variable volt device, you can achieve the same results using a higher resistance coil combined with turning the voltage up on your device. Doing it this way will draw less amps and thus preserve your battery life and give you a longer time in between charges. Remember, the higher the watts, the more vapor you get and the high the temp of the vapor. Heres an example:

Use this formula. Volts x volts / resistance = watts.
Watts / resistance = amps.

So lets use a 3.7v device and a 1.7ohm carto
(3.7 x 3.7) / 1.7 = 8.05 watts.
8.05 / 1.7 = 4.74 amps

Now let's use your twist. We will set it to 4.8 volts (the highest a twist will go) and use a 2.8ohm carto

(4.8 x 4.8) / 2.8 = 8.23 watts
8.23 / 2.8 = 2.94amps

See the difference? You get almost the same watts but draw a lot less amps.

The more amps you burn, the harder it is on your battery.
You also should never use a resistance lower than 2.4ohms on any battery with less than 650mah, it's just asking for trouble.

My batt isn't a twist, it's the eGo-C Upgrade variable volt (cignot). So, I can click to turn it off then hold the button down and it raises it to the next level which from what I understands tells itself what it needs to be at depending on what I am using.

Loving the calculator, Tj, thanks!! Buying a pack of cigs used to be so easy. Can't want until I don't consider myself a 'newbie' anymore and everything gets easy.

Mroutlaw, math was not my strong subject, HAHA! You do make it easy though, thanks BTW, your youtube vids are great!

Thank you.

And my bad, I misread, I thought you said you have the twist.

I am new and I hate my batteries, but I find this explanation a bit complicated... I have a 510 Joye. Are there any batteries I can buy which charge lasts a lot longer? Are there any that I don't have to worry about leaving too long on the charger?

The charger I have is the one that came with the starter's kit.

First and most important - you always have to be concerned with how long you keep a battery on the charger, and, never charge a battery unattended (overnight, while you are away)!!!!!!!!!!!!!!!

Are you using a cig-alike right now? 510 Joye isn't descriptive enough for me. There are of course EGO batteries in the Joye line that are 650 mah. There are 900 and 1100 mah batteries in the KGO and E Power's. Then there are tube mods (Lavatube, Silver Bullet, Provari, etc) with 2000+ mah. The tube mods are quite a bit bigger than the previous ones I mentioned.

The higher mah, the longer you can go between charges. The higher mah batteries will be longer than the lower mah ones. Example of size difference: SmokTek 1100mAh eGo battery - with 5 click On/Off

If you have a link to the kit you bought, we'll be better able to give suggestions.

Get you a Mod that takes rechargeable batteries. lavatube, joker, Provari ect... But you should always keep your chargers with in eyesight. Its very doubtful anything would happen but if it did you could end up burning your house down or something. The Joker is about the size of a 1000mah ego uses 2 16340 batteries and is 10 tomes the quality.

Hmm... That's odd. I bought it at vapor pro. The order confirmation said "JOYE 510 XL Black E Cigarette PRO KIT". However, the current description of the kit on the site (JOYE 510 XL Black E Cigarette PRO KIT) says it comes with four batteries. Mine came with two. I suspect they changed the product since I bought it. But what I have is basically that kit with 2 batts instead of 4.

Thank you for suggesting the stronger batteries. I will look into those with more mah that you mentioned. Will they work with the chargers I got in the Joye kit?

As for batteries being left unattended, I didn't mean traveling and leaving them behind. I just want to know if I have to remove them as soon as the light goes green, or if I can always leave it overnight. With the blu, you had to unscrew right away, or it would drain the battery charge.

This thread explains it all:

http://www.e-cigarette-forum.com/fo...ined-detail-single-dual-coil-atty-cartos.html

and this thread goes into it quite a bit as well:

http://www.e-cigarette-forum.com/fo...scussion/287578-single-coil-vs-dual-coil.html


Short answer:

Volts x volts / resistance = total watts to the coil or coils. Dual coils, divide that by two.

Amps = Watts / voltage required to develop those watts.

Higher resistance coils prolong battery life, so use the highest resistance single coil possible that you can power with enough volts to achieve the desired wattage. For me, that's around 6 watts or so, +/- 1.5 watts depending on juice, mood, and planetary alignment.

I encourage people not to use dual coils without a specific reason for doing so, since they require twice the battery power of a single coil to produce a given coil temperature. I don't consider "two must be better than one" to be a particularly compelling reason.

I also highly recommend variable voltage over fixed voltage, except, again, if a user has a specific reason for using constant voltage. One of my reasons to occasionally use constant voltage is that the Joyetech 18650 mod is just absurdly bad-... looking, like a Mark 48 torpedo, and has a cool, rubbery button with a great "clicky" feel. I don't use it much.

It can be Confusing…


Just remember that as the Ohms go Down, the Carto/Atty Runs Hotter. So a 2.4 ohm Carto/Atty will run Hotter than a 2.8 ohm Carto/Atty.

Running Hotter can give you more Flavor and Vapor. To a Point. But running too Hot and the Hit will taste burnt.

You might try the next Lower Ohm in the Stardust and see what it is like with your VG e-Liquid. You might like it. Or it may be too Hot and taste Burnt.

One last thing.

You can't compare the Hit with Ohms for Different types of Cartos / Atty. Meaning 2.8 ohms for a Stardust maybe perfect where as 2.8 Ohms on a Filler Type Carto may be Too High.

Excellent, excellent point. All the more reason for me not being able to understand very well why someone would recommend a fixed-voltage device over a variable voltage one. I wish that people would stop recommending kGo's, e-Powers, or any other fixed voltage device to anyone just starting out. I own them, but I don't use them or recommend them.

It's hard to make Any Reommnedation to people one way or another. Everyone has Different needs and Everyone is on a Different Budget.

For me, a VVPV is perfect. I can dial it Up or Down to find the Sweet Spot for any Given e-Liquid.

I did the Normal Progression.

Ultra Mini.
Mini Pen Style
Pen Style
Long Pen Style
eGo/Riva
Box Mod
Box Mod VV
Provari
Mini Lava Tube

I think the hardest thing when I started was Breaking the Size Barrier. I wanted things that were Analog sized.

Most people get to a VVPV sooner or Later. So I don't get too concerned when people recomend an eGo/Riva to someone using a Pen Style PV. Because an eGo/Riva is a Great PV and many people making the Recommendation arn't using a VVPV yet.

Maybe small steps is easier to take than someone saying your should buy a $225 Provari.
