Sub ohm battery chart vtc5?

Ohms law is all you need to know. Sony VCT5's are rated at 30A continuous and 4.2V. Ohms law V=IR can be rearranged to solve for Current (I) I=V/R so for your friends at 0.05 they would need a battery at I=4.2V/0.05=84Amps so they are lucky they haven't blown their faces off. Please don't be as stupid.
Just use ohms law as mentioned above. Anyway here's a quote from baditude.
Saw it happen at a local shop, dumb kids were messing around with "only a .09" build and had it explode on them...
And they were laughing afterwards?

I'm not talking continuous though. My build currently is .18 and I'm using a VTC5 battery. The battery is only used for pulse in sub ohm vaping. I'm pretty sure I saw a pulse limit before.
AFAIK its a 60a pulse, but theres a reason we dont drive our cars everywhere at 120mph even though many will go that fast.
I have seen this referred to as a "pulse amp safety chart":
That is NOT what this is. This chart is a guide for how long you may have until catastrophic failure, and is intended for creating safety cutoffs (e.g. fuse protection) for VTC batteries. This chart specifies that VTC batteries are to be cut off *over 30A* and absolutely does not provide a rating for use at these amperages.

I hope he doesn't have a sticky switch. I really don't understand why some people like to press their luck like that. If I was really into risk, I'd take up BASE jumping. It seems like it would be more fun than sub-deciohm vaping

Notice that it says <Xsec. I wonder how less than.
It likely varies with conditions local to the battery, I would assume these numbers assume some specific test conditions (including the cycle count on the battery).
Per MIT the standard for pulse is 30 seconds. VTC's are safe to draw 60 amps for 30 seconds or less.
VTC's don't "explode," they vent. There are some crazy things going on in the cloud chasing competition scene. I wouldn't do it, but other people doing it doesn't keep me up at night. I would have no problem running .2 builds regularly with VTC's though.

According to Ohm's Law Calculator:
Your .18 Ohm build @ 4.2V = 98 watts and 23.3333 amps
You should be safe with your .18 ohm build, but pushing the limit of your battery isn't recommended. Be careful...

I wouldn't put a 3 month old VTC5 that's being used daily under 150 amp load for even 0.1 seconds.
These charts are silly battery degradation and cell quality vary way too much for any respectable manufacturer to make a chart of this sort.
No one should follow those specs, don't EVER put a 30amp battery under anything over 20-23 amps for any amount of time, always make sure you've way below the rating.

I know. That was my point. You're pushing a limit that's fluid and not well defined.
Hence why I said 'please don't be as stupid.' Yes, but just because the VCT5 has a pulse limit of 60A doesn't mean you should aim for that with your builds. It will backfire and you will get hurt sooner rather than later.
It also depends on how much the battery has been used. Batteries does get degenerated over time. So i assume those 30s could quickly turn into 5 sec pulls etc.
Well it's quite moronic to even go into this territory.
To dependent on "luck" kind of. It might work for 2 weeks but the next week, the battery will vent on you.
They're not made for such high drains over time.
What happens when a battery expands in a mod, blocks the path to the vent holes and then vents? I've seen pictures of mods that were blown to pieces.
If you want to exaggerate the safety issues with pushing battery's well within their limits, more power to you.
