Try this link
may help
they have "Battery presets" Data Bank...
choose the battery
input the Ohm and
check the "Amp Limit" Box..
will show headroom % +/-

for 1 second bursts, you really can take authentic VTC series cells to around 60A ;-) I don't though, they're too expensive to abuse that much, and if you don't know how to actively diagnose their health by discharge rate and capacity over time, you probably shouldn't either.

The lowest I've comfortably vaped mine is .1oHm.

You have to keep the voltage sag/drop under load in mind here guys.

You don't get 100W very easily on a mech out of 1 cell in reality, and you must VERY CAREFULLY tread the line of a short circuit when you exceed 30A output form them.

In my aluminum nemesis, I get about 90W @ .15oHm, and in my copper smpl, I get 102W @ .15oHm for reference btw.

If you do it, it is at your own risk, and you should be able to actively and accurately test the voltage under load (and hopefully the amperage too), as well as be accurate to .01oHm with your resistance measurements (not easy to do and can take up to 3 devices / oHm meters to be 100% sure)

Should be noted that VTC5s actually have a lower continuous discharge of around 20A, unlike the VTC4s which are true 30A cells (albeit they just skirt under the barrier there).

VTC3 also has a true 30A unlike the VTC5

I have burned one on a 0.2 ohm coil...

and after , i question me and i find that :

It is advisable to not use a resistance under 0.3 ohms

You guys that say this, and similar, obviously got the fakes / clones...

There are a LOT out there.

My authentic VTC5 cells are still working good as new even after regular use @ as low as .1oHm.

Woah, mama!

I've seen various figures for sony batteries. The problem is that nobody has published the rest time or pauses between bursts. My guess is that it is dependant on internal temperature and also to give the chemistry time to stabilise again.

When you are pulsing above max continuous discharge be aware that you are dramatically shortening their life span. If you have to do it then best to do it on new batteries rather than old.

When I was younger I used to go skinny dipping. Now, all I can do is chunky dunking.
