Am I Stupid, Or Will This Battery Pack Handle 576 Amps?

[forks]

First the link to where it's sold and more detailed info and a look at the battery.
Turnigy nano-tech Ultimate 6400mah 1S2P 90C Hardcase Lipo Pack

Ok, now the math that I'm Probably Doing Wrong.
C-rating (which just stands for Capacity) is supposed to be the maximum safe continuous discharge rate of a pack.
As I understand it, to convert C-rating to maximum amperage, you convert the mAh to Amps per hour, then multiply that by the C-rating.
So, it should be:
6400mAh = 6.4Ah
6.4 x 90 = 576 Amps ... No?
Not that anyone sane (not that I am particularly such) would want to vape at what... 2131.2 Watts?
But the ability to handle such discharge rate in such a small form factor (3.6" x 1.8" x 0.7" for my fellow 'murricans) seems very ideal to throw in a box mod of some sort.

It is a battery pack with multiple cells inside. It is also down-volted, this is why you get this crazy Amp limit. If you want to use high drain battery packs, opting for a high voltage one is better.

Thanks, I've been thinking about building a box around something like an sx350 chip with a LiPo pack and a little usb charger board. This one just seemed so insane when I was looking at the specs, though I don't think it fits my use case at all.

you're doing the math right. but idk if it'll work for e-cigs. someone else can tell you that.

Your numbers are good forks and 576A is correct. Keep in mind though, at 90C your battery would be completely discharged in 60 minutes/90C=0.67 minutes which is 40 seconds, or ten 4 second puffs. It would also be way too hot to hold in your hand.

I also doubt a 90C LiPo cell actually has 3200 mAh. Sounds way high to me, but I've been out of the LiPo market for a few years.

A .32 ohm coil would only be 105,455 watts

eta: Just a hair too much for the DNA 105K

But you could run a 2.2 ohm clearo for 177 minutes or some 2126 5 second puffs, as per steam engine....

Yes, but what a waste of a 90C battery

Seems several folks have been building SX350 box mods with this exact battery. They claim no sag at all until the battery is dead and get 4-5 day's on a charge. I haven't used it myself as I can charge mine frequently. Here's the thread you may have to dig through a bit to find it.

Nano techs are often considered good batteries with decent output and discharge curves. Their crutch seems to be they have a reputation for 20% or more of their packs dying an early death. Some folks have reported less than 20 cycles on some of their packs with others going well over 300 cycles.

However...

You can generally expect to get most if not all or more of the rated capacity out of any lipo pack. It is a 1S 2P pack after all. It's 2 3200 mah cells in parallel.

Here's the kicker. NEVER expect to get more than half the continuous rating in BURST amps. Burst amps meaning MILLISECONDS.

If your calculations are correct I'd expect to get maybe 120 to 180 amps safely out of that pack for vaping purposes. I wouldn't attempt 180 personally... unless it was tested and monitored on a bench first.

Just to be clear, at these discharge rates, cells of this type need active cooling (fans or venting from a moving RC vehicle)...

Kanthal will melt at 120 Amps. Unless you use something like 14AWG.

lol can u imagine. no thank you.
