It's no more dangerous than vaping at 30w, if you have the correct spec battery to match the resistance of the atty there is no extra danger in terms of possible battery failure.

what spec battery is safe to vape at 200w with?

A 0.2ohm build at 200w only draws 31.62amps and 6.32 volts so a couple of 40amp 18650's would do the job.

ahhh a dual battery mod wasnt questioning you was just curiours

Not my personal taste either but there is a practical reason for higher wattage devices too for people who like to dual coil,triple coil or quad coil, the more coils you add or the thicker gauge wire you use the lower your ohms are going to be and the more power you're going to have to dump into them to bring them up to temperature.

Sooooooo what is the benefit of triple coils quad coils etc.?

I get bags of vapour and flavour with a single coil.......do the multi-coils double, triple or quadruple the vapour/flavour?

You have more wire covering more wick so yes essentially a larger volume of vapour being produced.
I seriously doubt there is anyone out there who vapes regularly at such high settings but there is no denying things like cloud comps etc exist so they do have a market.
Possibly other people who like to occasionally go all out at home too and on those occasions require the higher power.

Huh!
Puny Far East 200watt regulated devices.
I making 200watt UK Mech Mod.

[whiteshep]

In a simple term cloud chaser's for vape competitions even though at over 100 watts it is not enjoyable at all it's this so called "cool" part of vaping that a lot of young un's are into, spose there are worse things for them to do at least till we get a definitive answer on the whole how high temps affect wire, wick and liquid. 30 watts is as high as I go on my lemos anything over that and though vapour increases flavour degrades and I like flavour more then obscuring myself in vapour.

I think that this thread covers most of your questions:

Sorry to be the bearer of bad news here.There are NO 40 Amp continuous batteries, the 40Amp is the pulse rating.

Even with 30Amp batteries you still need 3 to vape safely at 200Watts regulated - a 30Amp is only safe to 75Watts in a regulated mod.

There should never be a single battery regulated mod rated over 75Watts. Similarly there should never be a dually rated at over 150Watts. Except the Chinese don't understand battery safety and are beginning to bend the rules.

The steam engine's Ohm's Law calculator is set to do the calculation for mechs with the default Volts setting. You need to reduce the Volts to 2.5V for regulated mods.

Yeah i know the steam calculator is for mechs i posted that to show that even without regulation 200w can be achieved from 18650 batteries and only pull 31amps.
If the batteries are wired in series it won't be pulling 31amps from both batteries the load is spread isn't that right?
All the huge power regulated mods like 260w jobs i've seen typically take 3 or 4 batteries in series or a Lipo cell, boards also output more current than the batteries input too don't they?
So the device could be delivering 40amps to the atty but it's not drawing 40amps from the battery/batteries.

[Ripshod]

The load is spread with batteries in parallel. Batteries in series doubles the volts but the atty current will go through both batteries (in a mech).

The OP is talking about regulated mods i would have gathered or they wouldn't have a max watts advertised.
It's not to say safety doesn't apply my opening point was there's no danger with high watt devices above and beyond lower spec regulated boxes, the same battery safety measures apply across the board.

I was only interjecting with the following two points:

1: There are NO true 40 Amp batteries.
2: As the OP is talking about a regulated mod and 40 Amp batteries are not available, a minimum of 3 30Amp 18650's would be a better (truer/safer) suggestion.

I'm not picking faults here Get Off My Cloud, just want the thread readers to have the safest information.

I hear you mate, i just assumed that the output of the board in a regulated device would be higher than what it needs to draw from battery, that's the point of a DC/DC converter isn't it to increase the input current?
So although a 0.2ohm build at 200w requires 31a output it shouldn't be drawing 31a from the battery in a regulated device should it?

That aside just wanted your opinion on these they are marketed at 40 amp and they classify continuous as anything over 60 seconds and i don't know anyone who takes a 60 second toke on anything.
Is this marketing BS on their part?

I can totally see the point in vaping at high power for TH and Nic hit, sure.

What I don't get is the flavour thing.... surely you can have too much flavour?

Most of the stuff I vape (I'm guessing) has been formulated (% flavour) to taste good on a regular atomisers.

Would I make tea with 6 times as many bags or orange squash with 3/4 orange squash 1/4 water?

I have a few liquids that are too strong at 20 watts... my current ADV is too strong at even 15w....

[Deleted]

Also the reason folk that are vaping at over 100w are moving more towards Li-Poly batteries ( I have used them for a good 5 yrs in R/C )

The problem then becomes that each cell in a Li-Po pack has to be balanced, and you then get into the realm of dedicated Balance chargers etc.

[Ripshod]

Get Off My Cloud, I think it's a bit of marketing {something} on their part.

The Vamped 18650 40 amp battery is 2300 mAh and packs a powerful punch pulse of 40 amps. A pulse rate is no longer than 60 seconds.

They already admit there that it's the 'pulse' rating, but they don't state what the pulse time is, other than it's 'no longer than 60 seconds'. Also stating the 40Amps is a pulse rating, we can assume these batteries are rated at just 20Amps continuous.

If there really was a 40Amp capable battery that was safe to use for longer than a few seconds I'm sure it'll be coming from a large Japanese battery manufacturer, not a vape store.

The other issue apart from the pulse time is the recovery time, the resting time between vapes - it'll need increasing as the pulse time increases.
