Research is key.
The RC community has been around for a long time. lots of good information out there on brands. In fact lots of the most respected brands of lipos are made out of the same Chinese factories.
That is true. BUT, we dont know which Lipos are being used in vape mods.
You are welcome to buy every vape mod with Lipo batteries, take them apart and let us know. No one is stopping you.
I guess I come from the idea of if I want to know something I ask. You want to know what lipo they are using, ask. Watch a review. Ask for internal pictures.
Finally, a new SX that I won't be buying.
Not interested in 200W.
Doesn't look like a good form factor for me either.
I do like the RX200 I picked up, but that's the sole multi-battery device I own.
Plus, after using the RX and the eVic-Mini, Yihi needs to rethink its menu system. Those two devices are easy to use with common parameters accessible without going into 3 levels of menu. Display too if they are up for making changes.

Its going to be a long wait for someone to take every DNA200 mod apart and test every Lipo battery with proper equipment.
Lets put a pin on this subject and get back to it in 2 years.
2 years is too long? Im tired, have a cold and dont have the energy to find a dissected review of SX Mini M Class.
So who reviewed and took apart bit by bit, screw by screw Yihi M Class mod?
Fwiw, there are a bunch of yihi sx330 powered mods which do 200 watts on 2 cells... Sort of. If I'm not mistaken, after about 160 watts or so the chip "pulses", giving repeated bursts of power, presumably to avoid overtaxing the cells.
Why the sx350 remained limited to 120 watts when the lesser sx330 chip received this update is beyond me.
Regardless, the supremely ergonomic form factor of the 3 cell powered reuleaux means that yihi is going to have a heck of a time unloading these new Q class mods, unless they're dirt cheap. Even then, yihi better bring their "A-game" on this one.

Looks good
Newer chip
Dual 18650
Looks like magnet back covers
Almost got the vaporflask sx350 until this came along

Maybe people should wait and see what it is.
OMG, so much discussion with no knowledge of Design/intent.
Still waiting for a true report of a Quality Battery Venting in a quality Regulated Mod design.
Every report I have seen so far has been Mechanical + Stupidity = Boom!
So far
Honestly, Yihi ignoring Safety we will see once they release Product and Details.

Finally the mod I've been waiting for since owning the M class. I could care less about the 200w. I never really vape over 100w. I wanted the extra battery. God knows I would use my SX a lot more if I didn't have to carry around 2 spare batteries. Now lets see how much they want for this bad boy.
My mistake, but it still begs the question of why the supposedly inferior sx330 does 200 when their flagship doesn't. Unless I missed that point along the way.
What's the sx350 limited to in Ti, Nickel, and ss temp control modes anyway, joule-wise? Been a while since I looked.
What a disappointment! From all the other Chinese mod makers I would expect this BS! But I thought Yihi was better than this! 200 watts with 2 18650's Don't work! I'm sure they know That! Evolv sure does, you can only get 133 watts from a dual 18650 DNA mod.
Hehe, youre going to add another 2 pages of battery safety to the already ongoing debate with that comment
For the record im on your side of the fence, and ill add this to get us (re)started
From the previous page, from apparently Yihi:
Just because you can test it, doesnt mean it should be done......much like trying to lick your own privates
Anyhoo that statement highlights a few things, which we probably already know (and should heed more):
1) Its a narrow resistance band you have to build to to hit 200w on 2 18650's. given that band is so small doesnt that already set off the alarm bells?
2) You need a battery with specs that so far seems rare (and genuine) from reading Moochs posts, to even get there. Again, alarm bells to me.
Given the hoops you have to jump through would you rather:
a) Market it, knowing as you do the problems with getting genuine and properly rated batteries, as 200w pie in the sky mod
b) Go against the trend of "more watts" and instead sell it as a 133w mod with an emphasis on safety, with specs that cover the actual majority of vapers.
I vote b) because selling some newbie a 200w mod, who doesnt read battery safety threads, and just thinking about them building a low ohm coil so they can hit the mythical 200w mark frankly scares me. Ive already seen one newbie recently join here after he bought a 200w mod and posted asking why his coil had disintegrated. I asked him if he had read the manual - No. In fact he had goosed a nickel coil with 120w in vw mode and wondered a) why it tasted bad and b) where the coil went. Too many people want to go right from a hairless preteen to a full pubic bush by buying a 200w mod as their first mod it seems.
People are now starting to get the impression that 200w is normal, its being treated as an entry point by some who must just think more watts is better (personally i blame the increase in tv screen sizes, and well some males really apply the ruler to everything) and dont avow themselves of the knowledge to know there are caveats, and a big one is battery safety.
Vaping needs to be as safe as it can be, mod makers rolling out 2 battery 200w badged devices isnt honouring their side of the safety puzzle. Its hard to reach a potential hazard if the ability isnt there in the first place. Sooner or later (hopefully never) some kid is going build a low ohm coil (of course likely not knowing anything about ohms law), put some cheap rewraps into one of the 2 battery 200w take a chancers and come away with a story to tell. Then he'll probably read the manual or read a thread, until that happens its really up to the device makers to assume primary responsibility or exercise a duty of care, rather than posting battery requirements which they know are hard at best to reach, for many factors not least being fake rewraps.
As for lipos, my first mod was lipo powered, and theres a few things i would personally say about them
1) When they run low, its like dropping off a cliff, theres no gradual downward slope. Of course i was never a great monitor of battery levels so id always get caught out when i was away from home. Nothing like showing up at the vape shop with 0 battery and no way of quickly resurrecting it or swapping it out. I think a lot of lipo users will be looking for extra packs, or staying close to a power point
.2) Theres no way in hell i would ever leave one on charge and leave the house, or go to sleep with the charger on. While they have been used in the RC world for a fair while, what theyre normally used for doesnt place the same stresses on the cells as what theyre now being used for in vaping, unless im mistaken. And given that you can go on youtube and type in rc model fire and get plenty of hits, like tempting fate with 2 battery 200w mods, id still be cautious with a lipo powered 200w device.
My comments about 200w mods are my own and i would happily own one using sane watts (the range that the bulk of vapers use) for better battery time (before i got the SX Mini M second hand i was seriously considering a DNA200 mod, i couldnt pass up the reliability of the SX though), but unfortunately that seems at odds with why a lot of people do or are considering buying them, and why newbies are showing up with them.
I came into this thread hoping for some real information my bad. Wait till they release and then have these debates, not saying it's the case but maybe yihi has found a way to get true 200 from two 18650's somebody has to be first with everything. As for evolv vs yihi I really can't be bothered with it and I suspect neither can most it's a fanboys pointless obsession and never ever contributes anything positive so both camps both make appropriate threads and have at it in those.
It's Math! how can they change that? Most vapours use 20 amp 2500 mAH batteries, they just can't produce 200 watts. It's very simple.
I have a few Yihi chip mods of my own, I know they make good chips no doubt about it.
This having to market a 200 watt mod, is just BS!
Not only do you need to consider the cutoff voltage, but beyond the cutoff voltage. Attempting to draw 33A from an 18650 would result in a HUGE voltage drop. As we know from other YiHi chips, the battery cutoff voltage may be 3.3V, but if you have 3.31V left, it will fire, and there will be voltage sag.
Lets say, based on their facebook comments, the cutoff voltage is 6.4V, and you only get a 1V sag when firing just above the cutoff voltage. You're now pulling 39A from the battery!
They've proven they don't know what they're talking about because they keep quoting coil resistance, which is totally irrelevant in a regulated mod when discussing battery current draw.
This is just plain irresponsible.
There is no 35A 18650 on the market.
They keep mentioning resistance, which is irrelevant.
Their current calculations are for the atomizer, not the battery.
They really have no idea what they're doing!
Only have 2 renderings (not pictures) of a proposed device to look at. Kinda early to get too worked up but will put this on my list to research when it actually drops. From the rendering it looks like the shell covers are plastic but we really would be guessing....
