Cartomiser ohm help

[grillman65]

OK, I need some clarification on volt and ohm pairing. I thought I read somewhere that you want to stay at 10 watts or below using ohms law, for best results. So, if you are using 3.7V, this squared is 13.69V and have a 2.5ohm cartomizer, you would be pulling 5.48 watts. So, this would be fine to use. But looking to buy the SD key e-cig, they say on their cartomizer page, "

BLANK 510 2.0 OHM LOW RESISTANCE CARTOMIZERS"(NOT FOR USE ON batteries UNDER 400 mAh ieO NOT USE WITH STANDARD 510 batteries).
​

Why? I thought there was a simple rule for all this stuff.

 

[daveymist]

Cause you don't want to go over the drain limit of said batteries. Most batteries have a c limit ie. Drain limit/current limit.

 

[grillman65]

But lower resistance means lower watts, which I would think means less drain. So, what is a simple rule for choosing the right ohm cartomizer. If using a 3.7V battery, use what ohm cartomizer(range). If using a 5V battery, use what ohm cartomizer(range). Lets keep this simple. Oh, and where do dual coil fall.

I've been trying to figure this out all week! So glad I'm not the only one confused by this!

Lower res. means higher watts. 3.0ohm on a 3.7v battery=4.5 watts
2.0ohm on a 3.7v battery=6.8 watts

lower mah batteries just drain too quickly and heat up faster with lower res. Some even have fried their higher mah batteries on 1.7ohm. This typically takes massive chain vaping and not paying attention to the fact the battery is getting warm. That's the simplest way to put it. Pay attention. If the battery seems warm, stop and let it cool.

OK, I know about Ohm's law, I guess I was thinking about this backwards. So, higher ohm means cooler battery. So what's the advantage of lower ohm cartomizers or attys.

The more power a battery sends to the coil the more juice that can be vaporized.
power = watts
Lower ohms = more watts = more hit, vapor and flavor.
More volts = more watts = more hit, vapor and flavor.

Using more watts will also drain your battery faster.

With the same voltage you will get a lot more hit and smoke with a 2.0 ohm cartomizer than with a 3.0 ohm cartomizer. To say a battery gives good smoke and hit doesn't really mean anything. It is the combination of battery votlage and cartomizer ohms that matters.

If you are going to use 2.0 ohm or lower you need a large battery for safety, battery life and just the ability to deliver enough current to a low ohm cartomizer.

 

[grillman65]

This make sense, so for someone like me who does not like throat hit, I need to stick with higher ohm cartomizers, among other things too.

If you are someone who Doesn’t want TH, you might find that 10 watts is a tad high for you watt wise.

 

[grillman65]

I will just need to take some notes and see where I'm at with wattage. Thanks for all the input.

Sorry for hijacking the thread but I also have a question on ohms and batteries.

I have a Lavatube and an eGo 1100 5 click, and eGo 18650 3.7v mod tube what cartomizer is safe standard ohm to use on all 3 that won't cause hot juice or batteries?

Good Call.

That or consider moving to a VVPV for your next purchase. The cool thing about a VVPV is you can find the Exactly watts that works best for a given Carto/Atty and e-Liquid combination.

I have both VVPV's (Mini-Lavatube & Provari) and Fixed Voltage PV's (eGo's). What I did was to find the ohms that works best for my Fixed Voltage eGo's. For a CE2 and the e-Liquids I use that was 2.6~2.8 ohms.

That way I can get about the same hit on a Fixed Voltage device as I do on a VVPV.

BTW - You can't compare ohms between Attys and CE2s and Filler Type Cartos. A 2.8ohm CE2 doesn't hit the same way a 2.8ohm Atty does or a 2.8ohm Filler Carto.

One more question, what is the advantage of dual coil cartomizers.

Dunno...

I don't like Filler Type Cartos. I tried a Dual Coil Carto and didn't think it was anything to write home about.

But YMMV.

 

[grillman65]

I do have one, infinity pro, love it.

 

[Charlz]

Seems most of the folks that like dual coils have VV or high voltage mods. Some with 3.7 and 3.4 voltage like them as well but seem to have stuck with them since they came with a kit or switched from atty tanks to them. I can say I get better results from single coils -and horizontals especially- but would never tell someone not to try for themselves.

Any carto that works on the smallest battery will work on the others. I'm not sure how low you can go but I would guess at least 1.8 ohms or anything higher..

One of the problems with low ohm cartos is to keep them wicking fast enough for the vapor that is being produced. By using two coils in a parallel configuration you lower the ohms by half. Now you can send twice as much power to the coils and still have the carto wick instead of burning.

And they eat juice insanely fast, at least in my experience.
