The battery rating is the maximum, you always want to stay UNDER the maximum for safety - if you exceed the maximum, your battery could run away and explode.
As I posted above (and you found out) building to .5-ohms will give you around 8.4 amps and 44% headroom, or margin of safety - meaning that you are using only 56% of the battery's current capability, and well under the maximum current for that battery. As a bonus you will get longer battery life out of the .5-ohm coil as well.
I think it's best that we try and give him the information because he's clearly intent on vaping his mech
I don't want him to go away without at least some advice.
It would be best to test battery voltage every now & then while you vape for the first few times so you get a feeling for when it drops below a certain voltage.
Recharging around 3.2v - 3.5v is a good idea, most folks find the vape changes a good bit when the battery voltage drops below 3.5ish v.

Do you know a specific charger that you recommend and something i can check out the battery volt? Like a
battery digital multimeter and if i wanna use my .28 coil i have to get a battery that can handle 20amp?
There are lots of good chargers out there but something like this one will do the job....

Yes regarding a .28 ohm coil I would suggest 20 amp battery minimum. 4.2/0.28 = 15 amps.
I would just buy the highest rated 18650 you can....see the link to Mooch's lists I sent you above. @Eskie gave you some good suggestions earlier.
thanks for ur advise but just letting you know one thing about me if i love something i learn it till the end i don’t say .... it its hard and leave sorry im not that type of guy
You could get a voltage tester to randomly check your battery voltage while you vape. Attaches to the mod's 510 connector to measure realtime battery voltage. Batteries should never be routinely drained lower than 3.4 volts. Drained below 2.5 volts will likely destroy the battery.

Ohh sh** I didn’t notice that im using the dual coils it changes everything no? How does that work now?
When using dual coils, the total resistance is halved what a single coil would be. For example, two 1.0 ohm coils will have a total resistance of just 0.5 ohm. So yes, it changes everything.
So always measure your finished atomizer on an ohm meter before test firing.

I like efest luc chargers, you can use any multimeter to test battery voltage.
How are you measuring resistance?
Resistance must be accurately measured & the build must be checked for shorts before using on a mech.
When using dual coils the resistance is halved.
2 - 1.0 coils = .5.
2 - .5 coils = .25
No matter what, resistance must be accurately measured & checked for shorts, coils must be adjusted so they glow from inside out evenly before use.

Are you using anything to validate the resistance of your build? You cannot just take a coil that is advertised as 0.3 ohms as an example and assume it is actually 0.3 ohms. Coil manufactures rarely spec their coils with the exact resistance – they usually round off the number to make it more attractive. AND….in some case they are grossly wrong.
I was given premade coils from a store once, it was a gesture of appreciation. Coils were rated as 0.25 ohms. Once installed they came out to 0.17 ohms and confirmed across many different resistance meters. That is a vast difference and with a mechanical device, can mean a lot.
There is also checking for a hard short. You may not catch every trimming from your coil once you cut the leads. This is critical on any device but with a mechanical it could mean the difference between keeping your face and not keeping your face.
If im using a dual coils with 0.78 it means I’ll be getting 10 amper with both coil and 44 watts? And then its safe to use it with a a15 battery
So I’ll be fine just using 0.78 and getting about 10 amper with 44 watts on my a15 battery?
Can you share the specification of your coil? Type of metal, what gauge wire are you using, how many wraps and what is the inner diameter of the coil. Example: Kanthal 24 gauge with 5 wraps and a 3mm inner diameter.
If you are using a Clapton type coil, I have my doubts that 2 in parallel come out to 0.78 ohms. If you are using a Clapton coil, please share the link where you purchase them.

Yes. But be sure to measure the coils on an ohm reader prior to firing on a mechanical.
Leave nothing to chance when using a mechanical mod. The only safety features you have are what's between your ears. Don't just rely on formula's or a calculator, or what a coil is "supposed" to be. MEASURE IT.
If you don't know what you are doing or understand what you are doing, you shouldn't be using a mech. These are not toys. You're using a potential pipe bomb if you are ignorant or careless. First vape related death

If you are using dual coils which when set up and tested on an ohm meter come out to 0.78 then you are drawing 5 amps total and you're fine.
If a single coil is 0.78 then in a dual coil set up they will read 0.39 so 4.2/0.39 = 10 amps so you're also fine.
@Pierre Marios I'm ducking out now but back tomorrow. The guys still around here will help you. Remember stay safe
You've been asked a few times & have yet to answer.
* What are you using to measure resistance? *
If you do not have an accurate way to measure resistance, stop fiddling with the mechanical until you do.
Seems you're confused & unsure of what you're doing, best to leave the mech alone until you understand what your are doing & why.
