The Persei is a WAY better deal than a DNA30 mod: cheaper and a higher power limit.
The cheap Chinese look-a-like boxes overstate their power output and have no warranty.

Yes they are chinese made and but they have 90 day warranty. I dont see how the Persei is cheaper? The Cloupor boxes are around $70, last I saw the cheapest price for a Persei is $169.

Can you point me to where you found that they overstate their power output?

I've tested mine on my multimeter and although the Resistance reads off by .1 (1.6 Ohm would read as 1.5 ohm) the voltage and power are correct and it can handle extended periods of 30w output. Most people are using these with 1.0 ohm-2.0 ohm coils @ 30w all day everyday.

There are a few known issues:
- 510 connector in the head is a little too large and can cause a short with atomizers who's center pin is flush with threads
- sometimes the unit requires 2-clicks to fire (1 click to turn on screen, 1 to fire)


Persei is still tank but this device, being 510 and having 30w is my daily driver since I can swap between my Kayfun and my Herc on the go. Also the on-board USB charging is nice.

Believe my guys when i say this the 8 is going to be the last vape you own.

Will have multiple lines of options.

Just wait for it and support us as much as possible.

Can we expect to purchase the 8 by summer's end?

Oh, and with a mechanical top, are all wires eliminated?

Don't worry about these chinese hoes, they are just keeping me over until the Iris and the 8. Persei is always my bottom bitch

@THC SCIENTIFIC Can I run two cells (7.4) on the 8?

The 8 will be capable of 3.7v and 7.4v

Exciting times indeed!

So, got my Persei today, and wanted to try it out with a "standard" Omicron/Persei 1.5ohm cart, but was reading the instruction set and saw that I can only run that cart with a single 18650 battery. Is this correct? Or can I use my two 18350's to run that cart? I don't want to ruin the cart of Persei, so any guidance would be appreciated.

As a side note, I did order a 18650 today, so waiting is not big deal if its a 50/50 proposition to run the 18350's.

Thanks!

You'd fry it with 2 18350's (7.4v). Wait for the 18650, and even then, go lightly on the button... 1-2 second bursts.

That's what I was afraid of....glad I asked. I will wait for the 18650. Thanks!

I think the DNA mods arnt the best for the Hercules for few reasons. 1 being

At 1.5 ohms resistance at 30 watts runs 6.7v and 4.47 amps.

But when the Herc heats up resistance changes to about 3.0ohms effectively making the battery run at 9.4v and 3.16 amps.

This is because these types of mods are made to run at the set wattage no matter what the resistance is. Effectively making the mod a ticking time bomb.


Someone please verify this. I'll have my engineers look into this but currently busy with other things.


DNA 30 vs the Iris


Iris does not boost so a set voltage of 6.7 delivers 30 watts to heat up as the resistance changes the watts change and the current drops. Effectively allowing your battery to run stress free.


In short mods are made for wire heaters aka outdated technology.

Did your Persei come with a handy-dandy voltage and ohm chart? The newer ones might not as they've moved to the KISS as the included cartridge. Here it is: https://www.planetvape.ca/images/Persei_cartridge_chart520.png

The 5.0 Ω cart will work great with your included batteries (7.4V config) and the 18650 you just bought will work with the 1.5 Ω (very short taps) and 2.4 Ω (Several second press) cartridges- *edit And also the 3.7V KISS which most Persei owners agree lasts longer than the 7.4... You can additionally use a shorty SS tube with just one of the included batteries for a mini Persei @3.7V too! Lots of options

Hmm, i've never seen my white rod read at 3 ohms(its gone from 1.5 up to about 1.8). I remember you mentioning this a while back when you first released the SR71. Basically you explained that it takes much more power initially to get the rod hot, then once its heated, it uses less power due to the higher resistance.
i dont run the dna30 above 25w with the herc, because its never needed. I would think that you agree with me since your SR74 is was limited to 28w instead of the 40w+ that the original SR71 could use - there was wisdom in that decision. The SR74 can handle anything thrown at it - shatters included.

The sr74 is limited to the voltage set that is being pushed out.

Your still using 1 battery to push a constant 25 watts no matter what the resistance is. When the resistance drops less current will be used to keep the rod hot, translating into less watts. Just saying it's not the best application for the Herc.

Also what are you using to measure the resistance when hot?

its a sh*t multimeter about 20$ and a 'omnitester', so i cant say its detailed. I see what you mean - persei just outputs battery voltage. I usually start it at 22.5w to get it going, but then i find myself clicking down the power to get the taste i want, so i end up around 20.5w sometimes lower depending on the concentrate.

Its really for when the herc is on the go. At home, the herc gets exclusive use on the Core.

Ive never owned a persei product but Ive always heard good thing. If you guys release a reliable portable herb vape Im down!

When I had a working Iris (god I miss my Iris!! ) I checked my 7.4v SR-71 heating rod resistance many times immediately after use (using the built-in Iris function) and never saw a reading above 1.9 ohms. This is a rod that reads 1.5 ohms at room temperature. (Also at room temperature the Iris measurements always agreed with my DMM.)

I have no doubt that a bare 1.5 ohm heating rod could get to higher temps and higher resistance when powered but inside the Herc the heating rod is bathed in oil all the time. Just as a pot of boiling water stays at 212° until the water boils away I believe the heating rod will stay close to the boiling point of the oil (400°?) unless the rod loses its oil bath. All the extra energy goes into making those massive vapor clouds we all love so much rather than raising the temp. Just as with the pot of boiling water turning up the heat just makes the water boil faster but does not raise the temperature. If the rod in the Herc ever becomes dry the temp will soar and you will scorch the oil that is close to the rod, hence the carbon build-up on used heating rods. This is what makes priming the Herc a bit touchy. You want to melt your concentrate into the oil coil but since the heating rod is bare initially you have to be extra careful not to burn the oil. This is why I go very slowly when priming or, if I get impatient, I just use my heat gun to speed up the process.

I like that the heating rod increases in resistance as it gets hotter. This is an important safety feature as it prevents the possibility of thermal runaway. I agree with you that a constant wattage supply is not the best match for the Herc.

Hedo

The white rod will survive thermal runaway on these DNA and DNA-like devices, only because the device voltage caps out at 8.3V. A black rod when dry burning is a recipe for disaster.

You can thank good o'l physics for that "feature."

Speaking of which, I blew my center spring, and will need to order another

What you're having to do is a function of using the "battery" you've chosen. I think what G means is it's constant varying wattage means the voltage it applies is increasing in relationship to the increasing resistance of the ceramic. This is causing you to want to turn down the setting on your battery as the rod gets too hot. What I'm curious about, not knowing a ton about e-cigs, is if in you set it to variable voltage and just leave it at 4v or 3.7V will that solve the problem?

If you were using the Persei you would be using straight battery voltage so it wouldn't be increasing in overall wattage. It would also be nicer to the battery. The circuitry of a vw/vv battery, is taking a 3.7v battery and stepping it up. the increased drain on the battery to create the higher voltage causes more strain on the battery, too.

On a separate note, I recall seeing some pictures of a nylon scraper/carving set that looked very handy for scraping out KISS carts posted earlier in this thread, but searches have yielded no results. Anyone recall what I'm talking about?

False alarm, my center spring is fine, I had pulled a @redijedi808 A quick isobath and I'm rocking and rolling again.

@SamuraiSam NoGoo Vape Scrape The Persei does not provide straight battery voltage, it has a buck-boost converter. When battery voltage is between 4.2V and 3.7V, it will step the voltage down to 3.7V. When battery voltage is between 3.7V and 3.2V, steps ups the voltage to 3.7V. Either way, the Persei drives the Hercules with 3.7V. You are right, in that there is no problem as long as the device drives the Hercules with a constant voltage. The problem with these Evolv devices (DNA12/DNA20/DNA30) and their look-alikes is that they do not give the user the option of selecting voltage. They only let the user select power, which leaves the device to decide what voltage to use.
