Sup guys. Not sure if thos is the right posting dpot but i thought it suited best. I just ordered a kanger five6, its a 5 battery 222w mod(i know, ridiculous and unneccesarry lol). Anyways im running it on tfv 12 and i needed the long baterry life. Im looking at the best 18650 to get and i wast thinking a pink samsung thats 3000 mah and 15amps. Im wondering if the amps used in a hit are divided up uppon the batteries, meaning the 5 batteries would mean a full charge could use 75amps safely(not that it would ever put tthat much out) or if reguardless the number of batteries it maxes out at 15 amps? Thanks a ton guys! Hope that mafe sense.

What is the coil resistance you running in the TFV12? Are the batteries running in series or parallel?

On a regulated mod neither of these things are important when calculating amp draw from the batteries.

The Samsung 30Q has a 20 amp CDR, and provides a great balance of power and mAh.
Have a read of this article to see how to calculate amp draw on a regulated mod.

@Izan, I was going to post the same thing but you got to it before I did.

@Tonee N, I agree with your post. Liion wholesale is the only place I order from. @Eliphillips420, they have the cheapest prices for authentic cells. I advise you to order from them. They also have fast shipping.

As @sonicbomb said, with a regulated mod you don't have to worry about this because the chip on the mod will take care of the calculations but that's no reason not to learn ohms law. I would highly suggest you learn ohms law. It's not that hard and can save you if you get into mech mods and building your own coils. I'm attaching a paper I wrote down ohms law that is easy to understand. I also agree with Somicbomb about the Samsung 30Q's. I use mostly mechs but when I do use my regulated mods I will use Samsung 30Q's because of the mAh rating. With the pic I use option 1, I will get the wattage and then use the calculation (amps, 3rd one down) to find the amps I would need from the battery and then use the correct battery for the amps needed. This is used when making your own coils and using unregulated devices but like I mentioned earlier, it's good to know.

Ohms law is not of use when calculating the amp draw on regulated mods, watts law is.

All that really matter is the watts.
A 222w mod with 5 batteries means you want batteries that can put out 45 watts each.

5 15 amp batteries should be enough.

I believe it's a "must know" law before hand though regardless.[emoji106]

1. There's no such thing as "Watts Law" in electrical engineers use of terms. It's simply called the power equation. Watts is the unit of measure for power in electrical terminology, like amps is the unit for current, and Volts are the units for voltage (EMF, electromotive force). P(power)=I * V = V(squared)/R = I(squared) * R.
2. Resistance always matters for safe vaping. Do you really want to rely on Chinese mods for your safety? I always ensure that my coil resistance is within the manufacturers specifications in the manual AND that my resistance is high enough so if a short to "on" occurs the maximum continuous current of my battery won't be exceeded. Regulated mod or not. Resistance, coil wire diameter, and voltage to the coil are all important parameters in determining the heat flux of the coil. Resistance matters.

1. No matter what it's called, amp draw should be calculated correctly.
2. Sure, but in that case the maximum volts the device can fire at should also be taken into account. A regulated mod won't simply act like a mech mod if the safeties fail.

Thats a smart thing to do and I do that as well. I never build below 0,5. I know most regulated devices will fire a 0,1 but whats the point in building so low? So if by a freak accident the mod will fire its max Voltage (9 Volts for most), I am still in safe territory.
I dont get what resistance has to do with heat flux, though; other then, yeah, you calculate your Watts via resistance and Volts...
