The sx350 is single battery or parallel only, or am I wrong? Pushing 3.2-4.2v to the voltages required for 150w+ might be difficult. I'm thinking that might be one reason, but I'm only guessing (and it's nowhere near an educated guess).

As for the pulsing over 150w, I really want someone to enlighten me on how that actually works and how/why it's safer.

Pretty sure it's single, or two in series. Positive, in fact, since the sxmini extension tube is most definitely a series type setup.

Ah, forgot about the SXM extension tube. I was thinking about the SX350j Valid Flask, that one has the batteries in parallel. Then again, any mod that will work with a single battery will also work with multiple batteries in parallel.

So how did Sigelei Fuchai acheved 200w on two batteries??
Does it do true 200w though? I haven't seen any tests where it's been put on a scope. Still, it's really not a question of whether 200w or more can be achieved with two batteries, it's about if it can be done safely. One could, theoretically, create a mod that does 300w on a single battery. It would do so for a (very) short while, and then the battery would fail.

Considering I'm not going to even attempt to use this over 100W I'm not concerned. I've been waiting for YiHi's answer to the DNA 200. Really anxious for more info.

I do understand concerns about newer and/or under informed vapers but shouldn't the lion's share of responsibility be the buyer's?

You are not wrong. Perhaps the new Yihi chip has something new up its sleeve that we have not seen on the market. Yihi has built a reputation and they wont throw it out of the window just because they decided to use 2 batteries.

If you look back few years, vaping 30w on single battery was insane, now we are safely vaping at 75w on single battery.

Be patient and let Yihi reveal its new chip.
I do remember the days using my then high tech eVic Supreme which is a 30W device getting real hot, almost too hot to touch, when using a Sony vt4 or vt5's when pushing close to 30W on subohm tanks. That was about 19 months ago which is light years in how things have progressed in the mod technoloty.

Sure, but a customer is in his/her right to expect a device to be safe in its intended use. Plus it's not like the common consumer would even think of batteries being potentially dangerous, I know I didn't when I started vaping. And, considering that most of the popular youtube reviewers are very ignorant on batteries, can a normal consumer really be expected to be more knowledgeable. Most vapers don't frequent forums such as the ecf.

I guess I don't understand people who would make this type of purchase without doing any research. When my wife suggested I switch to vaping to get off of cigs, I did a lot of reading before I bought an eGo and clearo. And then when I decided to upgrade, I read even more. I know a lot of people won't do that but it's hard for me to fault the mod manufacturers if buyers don't do their own due diligence. Do I wish YiHi would've limited the output to 130W or thereabouts? Sure.

I'm still waiting for more concrete info from YiHi about how the chip functions.

I did some research before I bought my first Ego kit, but back then that was pretty much all there was available for a beginner. Egos with basic ce4 clearos where pretty safe, in that you couldn't really push them too hard. Nowadays 100w+ mods are cheaper than my first Egos, and a many beginners will end up with one of those (better than starting with a mech). It was several months in before I bought my first replaceable mod, the Innokin SVD. That was only a 15w mod and while I did what I considered a lot of research and I still ended up with batteries that weren't optimal for the device. There's a lot of info out there and it can be difficult to find the correct one when starting out. Every day I have to school people on how amp draw actually works on a regulated device (and always someone fights against that information, like in this thread), and about actual amp ratings and bad rewrapps (again, someone always feels the need to contest that). As I said, if even supposed experts such as Rip Trippers and PBusardo don't have their facts straight, how can a newbie be expected to know. They'll trust reviewers. To this date I haven't seen a single top reviewer point out that two-battery 200w mods are dangerous.

And yes, manufacturers have a responsibility to create devices that are safe when used within their specs. In any other business a manufacturer will be behind liable when their device causes a dangerous situation, or when a potentially dangerous design flaw is found. Vape gear manufacturers should be held to those same standards. And, again, when a manufacturer such as Yihi demonstrates that they don't comprehend how amp draw on a vw mod works by talking about resistance limits and non-existent 35 amp batteries, how is a regular consumer supposed to know, or even find the facts when he/she gets bad information from a supposedly reliable source.

This is not about Yihi only, and while it's off topic I think it's a very important issue to discuss. This is educating vapers.

200w, two batteries, is about 35 amps (90% device efficiency and 3.2v cutoff).

200w(*1.1) / 6.4v (two batteries) = 34.375 amps

Sure, that doesn't exceed the cdr by much, but designing a device to exceed the safe parameters of the best batteries out there isn't responsible.

It has a high temp restricter plate though.

Even a 200hp car in the wrong hands is irresponsible. Yet we have 800hp street legal cars.

The fault false on the driver for being reckless and irresponsible with 800hp, not the car maker.

30hp or 30w, no one put a gun to your head to buy it or use it at full potential. But, it is your responsibility to be safe not to crash or burn your face off.

Even a scarecrow knew he wanted a brain. You have a brain, so use it to your advantage.
LOL

Since all the debate is based on battery safety and newbie/under informed users,

As long as they fit in the mod then go for it! lol Kidding! But if you should decide to do it please upload a good photo of your face so we can compare before and after photos. ha ha

It wouldn't be safe, but maybe a touch more safe than someone using those same batteries you mentioned in a two 18650 200 watt mod (more current draw from 2 vs 3 per battery at the same power setting). As a matter of fact it would be even scarier if they rated it at 300 watts since it seems like you can now magically get 100 watts per 18650 :nah:.
