so you cant run the sr74x higher then 7.5v? wouldnt around 8v be much more stronger?

If the rod comes in between 1.9 ohms and lower resistance (this means higher the number) then you can go up to 8.3v-8.4v

do you mean these? Which ones would be 1.9ohms and lower?


  • SR71 White Rod = 7.4V, 40 watts
  • SR71 Black Rod = 3.7V, 16 watts
  • SR74 White Rod = 7.4V, 23 watts
  • SR74 Black Rod = 3.7V, 16 watts

can i use the sr71 and sr74 rods on the hercules sr74x? which one do you think is better the sr71 white rod or the sr74 white rod.

No, the SR-71 rod only works on the -71. It will not work with the spring loaded post of the -74. The 71 rod is lower resistance and produces higher wattage so you must use different techniques than the 74.

so which one do you think is better? the sr71 or the sr74x. the sr71 one is available at ebay for 80$ but only one month warranty. the sr74x is 100. also a few post above how are you able to run your sr74x white rod at such a high voltage when thcscientific said itll only work for 1.9ohms or lower resistance works at 7.5v+.



SR-71 white rod is 1.5-1.7Ω - I don't go above 7.4 lol
SR-74 white rod is 2.2-2.4Ω - I might occasionally crank it up to 8.4

Every time batteries come off a charger they are at 4.2V. In series voltages add so that's 8.4V. Same as running 8.4V on the Core. Ohm's Law states E = I x R. Where E is Electromotive force measured in Volts. I is current measured in Amperes. R is Resistance measured in Ω or ohms.

Two ways here to get more power, voltage goes up and amperage goes down with the same voltage applied. Or decrease the resistance. Now we get our formula for power from James Watts. Watts law is: P = I x E where P is Power (measured in Watts) so you can see that both increasing Voltage or increasing Amperage or decreasing Resistance will create more Wattage.

Voltage is like the pressure in the water plumbing. Resistance would be a kink in that hose. The greater the resistance, or the higher the measurement in ohms, the more force (voltage) it takes to move electrons past that point of resistance. Or if you leave the voltage the same; the total flow (amperage) is going to be less. It's that Resistance to electron flow (Ω) that creates heat, and is the basis for electronic heater circuits. This is why a 7.4V Ti KISS cart at about 2.1+/- a few or -74 rod at about 2.3 ohms has a higher resistance than the 1.0 ohm 3.7v ti kiss cart or .8 ohm black ceramic heating rod. Lower resistance for lower voltage.

PS curious about why you cant run the 1.5 ohm 71 rod at 8.4V? Well actually on batteries you can. But the core has a 5 amp limit. Plug 1.5 ohms into those formulas and see what kind of amp draw you see @ 8.4V.

Very well said @SamuraiSam. I run the SR71 at 8.4v with fully charged batteries. It's a real powerhouse with fresh batteries. That being said, I have to be real careful not to hold the button too long or else I burn my load.

All this talk about rocking 8.4v... holy moly you guys are crazy. I like my 71 @ 6.6V or it just burns everything in very short order. I thought "fully charged" doesn't really mean much on the persei because it regulates the power to 7.4v? I almost feel like the Persei is a Pulse Width Modulation device because I hear my persei buzzing when I press the button sometimes... so that means it should be delivering a constant voltage to the device am I correct?

I was thinking about buying a kiss mini and a ss kit for my Persei so I can run one 18350(3.7v).So it will be super short and stealthy when out and about just wondering if the battery will be enough to get mabey like ten hits or so? Has anyone tried this and how did it work and how long was the persei all assembled? Or would I be better off buying a new vape?

If its like a kiss cart normally you should get at least a day out of an 18350... unless you use literally ALL day.

its there......but out of stock!!!!

Edit: Maybe just like G has hammer rods hes gifting out, maybe he has a spare 18350 tube laying around.....!

Oh damn. I wonder how long they are going to be out of stock I would take any color lol. I'll have to look around and see if any other sites have them. Would this do the same thing http://www.w9tech.com/the-core-18350-insert/ ? Looks mabey a little longer and I would much rather get both for $20 so I could stop having to adjust the battery all the time. But if they won't have the others in stock for along time might have to make due.

Not the same at all. That works with the core only
