Eaglewtchr Posted February 4, 2016 Share Posted February 4, 2016 I have been using a RDA for the last year or so. I have noticed that Sub Ohm tanks have come a long way. Is it necessary to use them on a regulated device or can I use them on my unregulated device? I have been looking at the Herekles and the Arctic v8. I'm leaning more towards the Arctic v8. My unregulated device is the SMY Kung Fu v4 parallel/series switch box. It uses dual 18650's or dual 26650's. I think I'm getting burned out on having to carry my e-liquid everywhere. If I have to have a regulated device I have been looking at either the Reuloux rx200 or the Ohm Wrecker g2. Link to comment Share on other sites More sharing options...
iQuit Posted February 4, 2016 Share Posted February 4, 2016 With unregulated box mod, I think you're fine. The main issue with subohm tanks are with hybrid mech tube mods. That is when the battery positive terminal is jammed up against the subohm tank floating center pin every time you fire it, and if/when atomizer floating pin gets flushed with the atomizer 510 threading, then you get instant dead short. Oh, and I think you will still be carrying juice everywhere with a subohm tank. Those suckers are thirsty, but you won't be filling it everytime as an RDA.

Eaglewtchr Posted February 4, 2016 Author Share Posted February 4, 2016 I think its the re-dripping every 15-20 minutes I'm getting tired of. I figure with a tank I could at least get couple hours before a refill. I just wanted to make sure it was safe. I have noticed that the coils are rated for different wattages. Since I have a unregulated does that matter? Link to comment Share on other sites More sharing options...
iQuit Posted February 4, 2016 Share Posted February 4, 2016 I hear you. I switched to RTAs/subohm tanks for that very reason. Coil wattage are guidelines. With Kanger Subtanks, even though some of their coils say can run up to 30W, I can't run it that high. I usually stay within 18-23W on stock coil. I am not familiar with arctic and herakles coils, and their recommended wattage range. But, if you choose a conservative resistance coil, run it in parralel rather than series, and most importantly know the limitations of your batteries, you will be fine. I am sure that our resident battery experts (jasonculp and earthling) will chime in, and give you more precise and detailed info. For example, I would not run a TFV4 0.15 ohm quad coil in 7.4V series configuration. I find more control with a purely variable voltage mod like Hexohm series.

Eaglewtchr Posted February 4, 2016 Author Share Posted February 4, 2016 So basically standard ohms law is still in effect. I run a dual 22g 6 wrap 3mm coil at. 19 ohms on my RDA. That should be about 94 Watts. So if I use say a .2 coil in a tank unregulated should be about 90 Watts. The Arctic .2 coils are rated at I think 80-100 Watts.

Earthling789 Posted February 4, 2016 Share Posted February 4, 2016 (edited) In an unregulated MOD, Ohm's Law is the only way it works, lol... Coil resistance and battery voltage determine the Wattage (output) and Amp-draw. A 0.2 Ohm coil fired at 4.1V (fully charged single battery or two batteries in parallel-mode) will draw 20.5A (minimum) and output 84W. This is safe as long as your battery (or batteries) are good batteries and rated 20A, like the Samsung 25R, Sony VTC4, or LG HE2/HG2. Now, in series, two batteries are capable of double Voltage (8.2V), so at that power level, the Amp draw will be 41A and 336W of output at the coil Your batteries won't handle that load, and @ 336W, neither will your lungs In a Mech MOD, there's now way to "dial it down" either... It's either full on, or full off, and the Wattage is solely determined by the coil's resistance and the Voltage provided by the battery/batteries! A regulated box MOD will make your vape more consistent and controllable, than dealing with the constant Voltage drop of a draining battery in a Mech MOD. I don't own either of the two regulated MODs you mentioned, but I've heard many positive things about the Wismec rx200. @jasonculp will be along shortly to give you more info on larger box-mods like the rx200. Let me add in this as well... Wattage ratings stamped on the factory coils mean very little... I frequently use a coil stamped 30-60W (for example) at a "comfortable" vaping range around 16-18W... to me, cranking it up to even 20W gives me a burnt taste, so you MUST also consider what your juice can handle... As I like to say... just because your car's speedometer registers 150mph, doesn't mean you HAVE to pull out of your driveway at 150mph!!

Eaglewtchr Posted February 4, 2016 Author Share Posted February 4, 2016 Ok. I understand ohms law since I have been building my RDA for the last 2 years. My SMY Kung Fu v4 box will fire down to .1 in parallel and .2 in series and has a 25amp mosfet. So as long I run .2 or above I'm safe. Just wanted to make sure that since I can't start out with a low wattage and break-in the coil like I have read about doing with a Regulated device if I run the chance of burning up the coil on first use.

That's similar to what I vape on some weekends (.2-.25 at around 80-90W), especially when I have some great tasting bakery flavors. However, I run reg mods. The only drawback I see is when you have a bad coil, and your mod does not have the ability to adjust the wattage accordingly. For me, one very nasty dry hit was enough for me to put my unreg device on stand-by. I still use it with RDAs, or even subohm tanks but with moderate resistance. Realeaux RX200 is a good choice if you are thinking of getting a reg mod. Ohm wrecker I am not familiar with but have read that it does TC with Kanthal.

Essentially, yes... 0.2 Ohms or higher will fall within the 20-21Amp range (and lower). Breaking in coils is not a necessity, but it sure does make them last longer and taste better! Also, starting out lower in Wattage lowers the risk of burning up (destroying) "partially wet" coil/cotton, although it doesn't eliminate the chance... I've toasted brand new coils at only 12W before I think once you try a regulated MOD for a few hours, you'll put your Mech's on the shelf and let them collect dust (I did, lol) Link to comment Share on other sites More sharing options...
Eaglewtchr Posted February 4, 2016 Author Share Posted February 4, 2016 Well, I do still have my MVP 20watt. But, It wont fire below 1 ohm. I used it with my KFL+ at 1.2 ohms. But, I haven't used either one since I started dripping. It did however get me off analogs. So, I do have a little knowledge on the regulated side. I just miss not having to drip 50 times a day. Just fill and go. Taxes are coming soon so maybe I can talk my wife into letting me get a new setup. I really like the Horizontech Arctic V8 there's like 8 different coil heads for it including a Snake, hive, and tiger coils along with SS and Ti and a Clapton coil heads. Quite a variety to choose from. And the RX200 from my understanding will do True 200 Watt without PWM over 150watt like most dual 18650 200watt mods.

iQuit Posted February 4, 2016 Share Posted February 4, 2016 Whoa... stop tempting me with the Arctic V8. Just kidding. They do look very appealing with it's wide range of coils. V-day is coming up. Wine and dine her... Link to comment Share on other sites More sharing options...
Eaglewtchr Posted February 5, 2016 Author Share Posted February 5, 2016 Umm, another thing I have noticed is that on a unregulated device ohms law is in effect. But, on a regulated device ohms law doesn't really apply. Unregulated at. 19 ohms 4.2 volts is about 93 Watts. Now regulated same .19 ohm coil you would run with less wattage. Or am I wrong?

iQuit Posted February 5, 2016 Share Posted February 5, 2016 Normally I do not like to recommend things that are entirely different from someone is looking for, especially when they already know what they want. But have you seen Aromamizer RDTA? It is literally an RDA with a tank. It is super easy to build even with thick coil gauges; it wicks great, no dry hits, and surprisingly does not leak despite of not having a proper AFC. I actually leave mine off. My only gripe is it does top-fill. Despite that, it is my number 1 overall atomizer. This may be good alternative without getting an entirely new setup before you are ready. @jasonculp: I enjoy your detailed explanations. It usually takes me several posts to make my point across whereas yours can be done in only couple. Link to comment Share on other sites More sharing options...
