200W with 2x18650? Again?
Does it have some difference from ipv3 Li?
I Think, 2x18650 can't give 200w.

If it's a parallel configuration it will be no problem for any cell such as a Samsung 25R or better (in discharge rating).

If it's a series configuration and the resistance limit isn't too low, it should be fine also for those same cells.

I highly doubt you can use it @ a full 200W in TC mode.

We vape pulsed output, not continuous, especially in chipped mods.

Woah, mama!

You'd prefer an oversized three cell or LiPo Evolv mod?

Whilst I personally don't advise it, a single battery tube mod can hit 200W safely with the right cells and short enough pulses.

Honestly, it sketches me out when people vape above their battery's continuous discharge current. My buddy vapes at .08 on a mech with old vtc5s. Vtc5 is a 20a battery and while it can handle 60a bursts pretty well, I don't see the point. I never build below like .14 on my vtc4s.

Plus, I always thought pulse was millisecond pulses not seconds?

I'm vaping a 120W build in my haze dripper on a copper SMPL with a vtc5.

Are you scared yet?

A standard pulse is 30 seconds on, and a rest period after.

Burst output is less than 1 second. BTW a Samsung 25r is burst rated to 100A.

120w is perfectly safe on a mech. 200w is pushing it, but can be done, sure. Most batteries have, what 100c safe cuttoff before damage occurs? Whats the point in destroying your battery just to pull 200w?

Have fun bursting a 25r to 100A @ .04 420W destroying your battery and having your vapour hotter than the sun. Your battery recovery time would be a couple minutes and it'd probably be dead in a few hits, not to mention take significant cell damage and vastly reduce the life of the battery.

It's only safe if you know exactly what you're doing and have the gear to match, for 1 (120W on a mech with 1 cell)

200w on 2 cells technically should be safer.

When did I ever say it was OK to vape at the burst limit of a cell?
It wouldn't work right. Puffs would have to be WAY too short and the rest time needed between bursts is too long to make it worth it. Not to mention you'd likely never get enough voltage to the coil to vape after vdrop comes into play.

Different ratings are for different uses.

Pulse ratings do not exist. Fabricated. Show me any true battery manufacturers that list a pulse rating (not a re rap)

That's a pretty big statement, especially if you look at a Samsung 25R datasheet and see the 100A max instantaneous discharge rating... (.5 seconds, and some of them even mention the 6 second rest period after too)
