    RDA Need help finding a specific Kennedy RDA clone

    I'm pretty sure FastTech has that version... nope, I was wrong. o_O But... if you buy two clone RDAs you can probably "Franken-atty" what you want. Combine a V1 Kennedy (two bottom holes) and a V2 Kennedy with the second, down draft cap... $23 to find out. Might want to be more specific than I...

    Build recommendation

    I've tried lots of complicated coil "styles", and some "stupid low" net resistances... but I keep going back to basic dual parallels from 0.2Ω ~ 0.45Ω at 40 ~ 90 watts. Quick - easy - works. Side by side dual parallels (two wires per post pair X two sets) is a quick and easy way to get, what...

    Build recommendation

    Ya' know... I'm going to refine what I said above... a bit. I use nothing but mechs, so I look at the wattage available for a given resistance, at 4.2 (or less) volts. From that, I have to come up with a build that gives me the most surface area... while staying within my heat flux range. I may...

    Build recommendation

    Coil surface area is the functional surface that you can expose a wick to... and all you really need is an adequate heat, in a reasonable amount of time. Theoretically, you can never have enough surface area... but then again, if that surface area is at the expense of other important factors...

    Build recommendation

    With 0.56Ω net resistance (I get closer to 0.60Ω at 12 wraps)... you have: 250.44 mm² per coil of functional surface area. Quite good. At 150 watts, you have a heat flux of 296 mW/mm². Warm, but certainly not overly so. Heat capacity (each coil) 105.74 mJ/K. A bit on the slow side, but common...

    Herakles .6 ohm wattage

    Around 30 watts would be the Ohm's law value at 4.2V. I suspect the coil head may be miss-marked - 50 watts would be more appropriate for resistance under 0.4Ω - again at 4.2V.

    Question for Mooch!

    I don't know 'J'... as we've discussed recently, and beautifully implemented by you... "THE ULTIMATE BATTERY CHART" is the go-to reference for them "Group 1" inquiries, and other than the Orbitronic, it's already alphabetical. In other words, take a break - would ya'. ;)

    Question for Mooch!

    The blue 25R2 Samsungs are in his blog/test list... 7th test down. Tests are chronological rather than by brand.

    Click on anyone's avatar and a profile pop-up provides pertinent details... like post count, or with this system "messages", which in your case is, at present, 46.

    advice with my new setup

    With that thick a wire - too thick for an 0.5Ω net resistance, dual parallel build - you'll need at least 90 watts to obtain a 200 mW/mm² heat flux (coil radiant temperature)... which is a fairly modest value. The alternative is thinner wire... the same build, but with 26 gauge, would require...

    Are my batteries junk?

    Never trust used batteries... and, hit the books to learn more about Ohm's law, battery safety and build modeling. See second sigline below. You can run your build data through Steam Engine to determine what you're calling ramp-up time... or, time to temperature. If you look at the "results"...

    Standard vs. "MicroCoil"

    When heated, Kanthal wire (iron-chromium-aluminum) builds up an aluminum oxide insulative coating on it's outside surface that protects the individual coils from shorting, one to another. This is called alumina (Al2O3). This is most clearly noticed when you test fire a new compressed coil...

    Need a refresher on Battery safety in series/parallel reg. Box mods.

    Dual series doubles voltage. Dual parallel doubles the potential wattage / amperage... at the output. Wattage (for the purposes of calculating SE heat flux values) will be the result of desired net resistance and voltage... in the case of a dual parallel, will still be 4.2V. The OL derived...

    Need some help converting to non regulated

    If you remember that with a mech, Ohm's law provides your wattage value... and only a few things will change that value. If you toss out the 4.2V constant (I personally use 3.9/4.0v as constants), then really, all you have is net resistance as a controlling variable. No net actually, because...

    Need some help converting to non regulated

    Remember that you're dealing with Ohm's law... The calculated wattage doesn't care about your wire gauge or coils in parallel count... just the net resistance and battery voltage. Heat flux does care about the wire gauge (AKA wire surface area & mass), coils in parallel count and net...

    Aspire 40A 18650?

    Nope. Look up Mooch's full test data in batteries/chargers.
