1.8 vs. 0.8

[danibanani]

Hello,

I have bought ten 1.8 atomizers (because it was the original that can with the Genitank Mega) but then I went into their B&M store where they recommended a 0.8. I bought five 0.8's. I was so overwhelmed by all the information they taught me, for the life of me I can't remember why they told me to go with the 0.8. However, I DO remember them telling to use up all my 1.8's before moving down to the 0.8 because I wouldn't want to go back.

What is this and what is the rationale? I'm so sorry for all of these questions, I hope there isn't a limit on how many threads one can make in a week.

Thank you,
Dani

LOL, nope, no limit at all! Dani, what battery do you have?

3- 18560's

oh boy.......

Whats the amp limit of the batteries? (Brand too) If I understand the Genitank right it holds two coils. So two 0.8 coils will give you an overall resistance of 0.4.

The .8/1.8 refers to the resistance, measured in ohms, of the coil.

The readers digest version is lower ohms= warmer/more vapor at the expense of shortened battery life.

Depending on your juice you may get better flavor or different flavors emerging. It's all about experimenting with different juices and finding what juices play well at different resistance readings.

Make sure you have batteries that can support low ohm builds.

You can really get into the science of ohms/resistance/etc but hopefully this helps. I'm not sure as I haven't had enough coffee yet

OK. With mechanical mods that you put the 18650s into you'll be getting more power (watts) from the 0.8 ohm heads than the 1.8 ohm ones. Here's a Ohm's law online calculator. Plug in 4.2 volts (your battery when it's fresh off the charger) and 1.8 ohms and hit enter. You get 2.3 amps battery draw and 9.8 watts. The watts is how much heat you're pumping into the atty. More power makes more vapor and flavor, but your wicking and air flow needs to be able to keep up or you'll get burnt hits.

Plug in 4.2V and 0.8 ohms and you get 5.25 amps battery draw and 22 watts.

If you have a regulated mod instead of a mechanical mod let us know that and what it is because that changes things in that the mod needs to be able to handle the lower resistance or you're going to have grief.

Most 18650s can handle 5.25A but as you get into subohms you need to make sure your battery can do it.

Dani I know you have mentioned eGo batteries elsewhere. You can't use those 0.8 ohm coils on eGo type batteries. The batteries simply can't handle a resistance that low.

I don't know the Genitank, but if it takes one 0.8 ohm dual coil head the total resistance will be 0.8. If it takes two 0.8 ohm heads, the final resistance will be 0.4.

Dani said 18650s Rick. No idea what they are in though.

Youre right. It only takes one coil. I got it confused with this one.

My apologies. Carry on.

I have seen Dani post that she has a Silver Bullet. It comes with a protected 18650 battery. That is the standard battery AltSmoke sells with their Bullet. She also mentioned she picked up an ego twist.

Thanks Susan . The standard Silver Bullet battery is an Efest 3100 mAh. From what I can tell that's a 10A continuous discharge battery, so just fine for 0.8 ohms.

The Twist only does 2.5A so should not be used with a 0.8 ohm setup. It's not dangerous if the Twist is OK, it will just shut down. 1.8 ohm dual coil is also pushing this battery.

Yes! This.

My battery for my manufactured (I bought it right from Altsmoke, I didn't build it) Silver Bullet is the Efest 18650 3100mAh 3.7v Recharageable Battery.

I hope these 0.8's work. I bought five

Thank you for all of your help!

Seems like everyone has to try sub ohm. Some will figure out how to do it and like it, others will not. My personal opinion is that someone is going to get hurt by using these coils on a wrong battery. BAD MOVE by KangerTech!

The real difference is that 0.8 ohm coils will be pulling more amperage (5.25a), which is above the safe limit of a Lithium Cobalt battery.
But the issue she will notice is that the 0.8 ohm heads will require more air flow and better wicking. Otherwise the vape is going to be to hot.
It's a big jump from 9.8 watts to 22 watts. IMO these heads belong on a regulated PV so that there is the option of turning the power DOWN.

TJ,
I am so, so sorry, but I don't really understand some of the verbiage of your post. Is the silver bullet a regulated PV (I don't know what that is)? is my 18650 battery running at 9.8 watts and then by using these 0.8's will jump it to 22 watts and make it unsafe?

Thank you for any clarification and I'm so sorry that you have to dumb it down for me.

Isn't the Silver Bullet a mech?

Easy way to say it: don't use the 0.8 ohm coils on the ego (Twist).

Better yet, No one should be buying or using sub ohm coils and or mechanical devices with no protection, without first learning the basics including ohms law. That ill responsible on the sellers part IMO. Its important to know what your devices can handle and what type (size) batteries to use.

Your Silver Bullet is unregulated; a fully mechanical (no circuitry) mod. Regulated PVs have some kind of chip that gives you the option to adjust the voltage (and therefore wattage) that's delivered to your battery. With a mech, you have one option: pop in the battery and push the button. But with a regulated device, you can adjust the voltage/wattage to adjust the vape.

You're right that the new coils will supply double the wattage (heat). Since it's staying within the amp limits of your battery, no harm there; the new coils are no less safe safe than your old ones.

What TJ is saying is that, since you can't adjust the settings at all, you may find that the new coils produce vapor that's warmer than you like, or uses juice more quickly to the point that you start to get dry/burnt hits. 20 watts between two coils really isn't too bad, but I've never used that atomizer.

So the only danger is that you may not like the new coils as much as the old. They'll certainly be different, but hopefully for the better

The summary is this:

1. .8 ohm coils will not work on your EGO battery

2. .8 ohm coils will work on your silver bullet

3. You should probably be sticking to 1.8
