Hello guys., i'm using samsung ICR18650 22f on my regulated mod, rx2/3 to be specific., i'm using it for almost 1month at 30w-35w in .24ohms., as far in my expirience the battery is not even get hot., but really i'm not sure with the battery so i would like to ask if what possibly can happen in the battery if it fail???i know the amp of that is too low for that settings..
I'm using samsung ICR18650 22f on regulated mod..

I just try the battery cOz the battery is just sitting only for a long time and no use...but when i use the battery i always check the condition like the temp., and i'm using that for almost a month without having a problem., and sir it really last long..
I did a brief search via Google of "samsung ICR18650 22f" and this came back:
If this is correct then your battery is rated for a 4.4 Amp discharge. I don't know if that's constant or burst discharge. It doesn't really matter though. On a 0.24 Ohm coil, 35 Watts = 12.08 Amps and 30 Watts = 11.18 Amps. So, I don't know, maybe you will be the next person we see on the news who gets killed or seriously injured in a vape related incident because you didn't use the correct equipment?
Maximum current of that cell is 4.4A, you are drawing around 10Amp.
You are going to get problems if you do not stop.
Like venting or explosion.

Vaping Battery Safety - Part 1

Never exceed the amps of your battery. This is a fundamental rule of battery safety. Take the discharge rate (the amps) of your battery, then divide your voltage level by coil resistance (ohms) and make sure you never exceed your battery’s amp rating. We go into this in more detail in the section about Ohm’s Law below as this is a vital step in vaping safely with non-internal batteries.

Ohms Law
Awareness of Ohm’s Law is arguably the most important part of safely using a mechanical mod. Ohm’s Law looks at the relationship between power, voltage, current, and resistance. It’s based around the amp of the battery – this amp rating is the current of the battery, in other words the ability of the battery to release the energy stored within it. If the battery is pushed beyond its limit, the battery can vent, which means dangerous chemicals leak from the battery, with a risk of it exploding.
Firstly, check the resistance of your coil and work out the amps the coil will pull from the battery. You can do this by using this equation: Amps = Voltage / Resistance. Don’t be put off, it’s quite simple. Use a multimeter to find out the voltage of your battery, and the resistance of your coil (be sure to work within a ±0.2 ohm range). You can use an online tool such as steam engine to help with this. The result should never exceed the amp rating of your battery. If it does, you’ll have to use a coil with a higher resistance.

You have two of the same battery? You're not using it at the same time with another kind of battery in the second slot, are you? (Does the 2/3 work with only one battery?) That opens up a whole 'nother set of problems, if you do that...
One more time, say it with me now kids: "resistance does not affect the current draw on a wattage-regulated mod." Amps drawn = watts setting / battery charge state (use the low-voltage cutoff point for safety calculations, call it 3.0v under load if you don't know the actual cutoff of your device.) Then add 10% to actually power the device itself, and you have a rough estimate of the max amps you will be drawing at a particular wattage. With 2 or 3 or 4 battery devices, the load will be shared evenly between all cells. The calculations are different if they are wired in series vs parallel (you multiply in one place, or else divide somewhere else) but the answer comes out the same either way. 30 watts, on 2 batteries, at 3.0 volts cutoff, is:
Amps = 30 / (3.0 * 2) = 5A each cell (+10% = 5.5A) in series
-OR-
Amps = (30 / 3.0) / 2 = 5A each cell (+10% = 5.5A) in parallel
...you'll still want to replace it with a proper IMR battery, though, ICR's are not what you want to be using. Check out @Mooch's blog for his latest battery charts, tests, and suggestions.
Welcome and glad you joined. I have provided a little more information which might help choosing/evaluating batteries.

I'm using this battery on Istick pico , vaping at 17W 1.7 Ohm discharge is at 3.0A I think I'm safe
You thought wrong, the ICR18650 22f is the wrong chemistry for vaping use.
When something goes wrong they vent by expelling hot gasses, rapid cell expansion & fire / flame.
Resistance does not factor into battery amp drain when using a regulated power device.
At 17w you're demanding 5a - 6a from the cell, the one you're using has a 4.4a CDR, exceeding any cells CDR is unwise.
Hmm......tested on my predator mod (have A drow counter). It says 03.2A discharge.
03.2A discharge at 17w & 1.7 coil
Maybe mod is not counting correct ?
Anyway thanks for info I think I'll stop using that battery .
Mods usually show you the output Amps not the Amps drawn from the battery. You're drawing 17W +10% = 18.7W from the battery, now you can calculate with the battery voltage. The most important point is the low voltage cutoff, let's say it's 3.2V, then you're drawing up to 18.7W/3.2V = 5.84A.
Those cells are the wrong type for vaping, we want to stay over a certain voltage (mod low cutoff) for as long as possible and need batteries with a very low internal resistance. Low discharge cells typically have a relatively high internal resistance and you won't be able to take advantage of their capacity. A high drain cell (15A+) will most likely outperform the 22f by a long shot (especially looking at the stated capacity of the 22f).

The amps displayed on the screen is a useless & meaningless output amp (from 'chip' to delivery device), it has nothing to do with input - the actual draw/drain from the battery(s). (from battery(s) to chip)
Resistance plays no part in calculating battery amp draw when using a regulated power device.
