I am lost, whats the point of high ohm?

[tntmux]

Hello, I searched all around the internet and this forum for information about high ohm clearos, what I gethered as info shows that with high ohm we get cooler and less vape, since I prefer warmer vape and I certainly want to make huge quantity of vape I failed to see the advantage of high ohm, the only pro of high ohm is it drain bettery slower and longer clearo life...am I right?

I really dont care that much for bettery drain, I currently run with 1.8ohm clearos, with my stardard 1300mA ego bettery it holds nicely.

For the longer clearo life I have no idea if high ohm will hanging on for much longer than low ohm or just a little.

Still, people looking for all kinds of mod with VV or/and VW options, personally I ordered vamo v2 from fasttech and still waiting for delivery. But if we take low ohm clearo such as 1.5 or 1.8 ohm, with standard ego bettery we can already get up to 8-10 watt so already in sweet spot range. So mods lost all its points...

Please teach me, thanks.

I've been vaping a couple weeks on my Halo e-cigs with 2.2-2.4 ohms. Seems to be their default. All my flavors come out good with a decent burn (my nic rate is 12-18mg usually). I have vaped most types of nic from halo (except menthol) and they taste fine, with little steeping (say 15min to one day). Im testing out other brands flavors soon (like xtc, pink, mister-e cigs, etc etc).

It is like you said, higher the ohm the cooler it gets, i have some 3.0 laying around and dislike it personally, but I like 2.2-2.4 and will probably not go lower unless the flavor deems it necessary.

Higher ohm needs more volts to get a good vape and lower ohm is opposite .i use 1.3 ohm and 3.4 volts on my provari.

 

[boltcigs]

The higher ohm is usually needed for the lower mah batteries. The low resistance of 2ohm or lower can sometimes be too much stress on batteries of 300mah or less. It really depends on the battery you are going to use.

I agree on that too. Lol, many variables to coinsider.

Someone who created the Safe Vaping Power Chart wrote an article explaining how using different resistances and voltages can improve your vape and help you find your "sweet spot". It may help explain your questions.

Agreed, but all those mods out there such as vamo, zmax, zvic, lavatube, they all have good mA, at least 1300mm, some goes up to 2600mA. For me the only reason we want a vv mod is to have higher voltage to support higher ohm, but if it is like you said, these betteries dont have low mA, so no problem...am I wrong?

Thanks for the chart info!

I personally saved this pic on my computer, but it does not explain the advantage of high ohm clearos, on a standard ego bettery which varies between 3.0-4.2v, according to the table, we have also have "best vapor and cartomizer perfermance" with a 2-2.2ohm...

First off, mAh is miliAmp hours. It is a rating of expected battery duration, not of power output (voltage or wattage). 100 mAh = 1 hour battery use. A 600 mAh battery should give approximately 6 hours of use. MAh has nothing to do with how powerful a battery is, only how long it can be expected to be used effectively.

Heating coils have an ohm or resistance rating. It's a measurement like a lightbulb uses watts to determine the amount of energy it will use to make light.

Lower resistance allows more electricity to be used and more heat is created. Higher resistance restricts the amount of electricity to the coil, BUT the amp draw on the battery is less than with a low resistance coil. It's a misnomer believing low resistance is easier on a battery, and high resistance is harder. The amount of amps pulled is what determines the draining of the battery.

A higher ohm coil will allow a larger range of higher voltage to be used than a low resistance coil. You can see this from the chart. It will also provide a somewhat cooler vape. Low resistance coils may cause some flavors to taste burnt.

The chart was designed to be a general guideline. There are vapors who use LR coils at extremely high voltage (wattage). That's what they prefer. This likely will decrease the durability of the LR coils at that voltage. There is no ONE WAY that's best. Whatever works for you stay, with it.

Using a fixed or single voltage battery, you would not typically use a high resistance coil (3.0 ohm) unless you know you prefer a cooler vape. High resistance coils were designed for higher voltage use (3.5v to 5.0 volts).

With an efficient boost circuit powering a ~3 ohm device at ~5v, most people will get more time between charge cycles on their batteries. This is mainly due to the fact that lower resistance coils require a higher amperage draw to get to the wattage output, even if they do require less voltage. For example:

2 ohms @ 4v = 8 watts (drawing 2 amps)
3.2 ohms @ 5.1v = 8.12812 watts (drawing 1.59375 amps)

The higher the amperage draw, the more work the battery has to do to deliver the power, therefore shortening the life of the charge cycle. Again, this really depends on the efficiency of the boost circuit in the PV, as a poorly designed boost can easily negate the advantages.

Stacking batteries in a mod is in disfavor. It's common to see LR or SLR stuff with a single battery.

In the "old" days, people stacked batteries and used High Ohm stuff with High voltage (7.4 volt) systems.

HighER ohm stuff (like about 3.1 ohms) is common for 5 volt vaping. Some devices used fixed voltage regulators with stacked (usually protected) batteries

The main thing is to not exceed the max amps of ONE battery for the whole circuit. Amps don't add from a max-allowed standpoint. No matter how many batteries you put in series...the max of the lowest one is the max of the circuit. Furthermore, they have to be balanced and all in good shape. So you don't want to mix old and new batteries nor have a major voltage imbalance between the two and try to draw max amps. Also, you should have at least a couple of "levels" of protection...aka a regulator and good vents. May also use either safe chemistry batteries (IMR ish) or use protected batteries (unlikely that BOTH protection circuits will fail at the same time if they fail at all).

Woahh! Hold the phone. The capacity of a battery is VERY important when drawing a large amount of amps! ESPECIALLY when running a low resistance! The lower the resistance, the higher the amp draw is. Simple rules of electricity. Too high of an amp draw can damage a small 300mah or less battery. I dare ya to try a 1.4 ohm cartomizer on a 280mah battery and tell me how many puffs it takes to destroy the battery.

 

[AttyPops]

OK bolt. He was talking terminology, not the details of battery construction and internal resistance (and "C" rating). So you're both correct from different vantage points.

Note that the max-amps for a battery at a given mAh capacity can vary due to battery chemistry....hence high-drain IMR batteries and NiMH mods, for example.

P.S. He knows all that too.

It's good that you point it out though. Communicating is tough.

I use 2 2000 mah rechargable AA duracell batteries in a vuzix eye wear device (slightly off topic) and i'd like to add that they last about 1 and a half hours. 2000 mah batteries may well last 20 hours in an apv, but in no way does the mah determine how long a battery will last until it needs charging because it depends what the battery is being used in. An apv user may draw on their device 6-7 times a minute so won't really drain much power compared to a device that needs power all the time. So unless "mah" is an exclusive reference to apv batteries, which it isn't, then mah doesn't determine how long the battery will last before needing to be charged.

"Milliamps Hour (mAh) is important because it's the easiest way to distinguish the strength or capacity of a battery. The higher the mAh, the longer the battery will last. Batteries with different mAh ratings are interchangeable. If your battery is rechargeable then the mAh rating is how long the battery will last per charge.

Milliamps Hour is 1/1000th of a Amp Hour, so a 1000mAh = 1.0Ah

Think of a cars gas tank. Voltage is how much gas is being used, and mAh is the size of the gas tank. The bigger the gas tank (mAh) rating the longer the device will run. If your battery is rechargeable, then think of the gas tank as refillable (rechargeable)."

Your own milage may vary.

Baditude's pseudo-defence here again (boy...bad...you're going to owe me a lot of beer....)

The 1 hour per 100 mAh is a very rough vaping estimate. For vaping. Intermittent use of the button. On average. On an average mod. Averagly

I can honestly say I've never got an hour of vaping per 100mAh. Might get there with a 3.0v battery and 4.0ohm carto...

I understood the gas tank explanation.

So the "hours" you are talking about aren't 60 minute hours, Which are the hours i understood you meant, but a different kind of hours altogether.
