Just getting into RDA (trident v2) help needed on setup.

[big spuds]

Hi all, I have been vaping for over a year now and have tried and even had my own online shop, selling lots of different vaporisers, atomisers and accessories. I own a vamo V3 and and itaste SVD. Among lots of other tanks and usual ego style batteries. I currently favour the iclear 30 tanks on my mods, but now am looking into getting in to dripping. I understand it is not for noobies (building your own), so I have spent the last few days watching videos and searching forums for advice.
The RDA I have chosen and ordered is the trident v2. I have a few questions regarding setup. The wire I have ordered is the kanthal A1 wire 28awg 0.32 x5mm. And I intend to use cotton as my wick based on reviews/taste.
Having watched various videos I am confident at having a go at making my own coils. I have a multimeter to check my setup but I am a little unsure to what I am looking for as a safe reading. I intend to use the trident on both of my mods. The batteries I have are efest 1500mah imr18650 3.7v li-mn. What kind of reading should I be getting from the coils to achieve a safe setup. And what reading would be dangerous. I did see somewhere that a set up could also be dangerous if allowing the batteries to get to a low rate of charge.is this correct? As I previously said. I am new to this, I am trying to do it all right and safely and we all have to start somewhere. Any advice, tips or help would be very much appreciated. Thanks in advance....Marc.

Hey hey

First off, are you going to be using your Vamo/SVD, or are you looking for a mech? If you're using a regulated device, safety is much less of an issue as the device won't fire if the resistance is lower than it's threshold. Your Efest 1500 (1600?) mAh 18650s typically can fire down to at least .5 ohm builds, some even as low as .3. This is largely dependant on the amperage rating of each battery. I highly recommend a pair of 30 amp max discharge rated batteries, its overprotective for most builds but that's not a bad thing.

As for what reading you aim for in resistance, if you're just starting to use an RDA, I'd highly suggest staying away from the subohm range until you get more experience. Build some 1.5 ohm builds, as closely as you can, and eventually you'll learn the number of wraps to wire gauge to coil type, and you'll be able to hit your build aim most of the time. Keeping notes might help in this regard.

You mentioned you're looking at a Trident V2. It's an impressive RDA, and will allow you to experiment with basic coil builds all the way into more exotic builds later on if you feel inclined to do so. Just research as much as you can, and build build build. As long as you're using safer batteries and test your resistances before you fire your builds, you'll be fine. ^_^

I am fairly new to RDA's myself, but here are a few observations. Your Vamo and SVD are both regulated devices, so your batteries will be fine in those. Your only potential problem will be that your devices won't fire below a certain resistance. I own an SVD, and it will not fire below 1.2ohm, I don't know about the Vamo. That is a dual coil dripper, so you need to half the resistance of the coils, ie. (2) 2ohm coils wired in parallel will result in 1ohm resistance. Here is a good tool to use to figure all that out.

Other than that, experiment with wicking, and the distance of your coils from the deck. Both of those factors make a big difference. Have fun!

Thanks for your reply, your question mark after my stated battery, confused me and made me double check....I was right, that's what they say. I will be using my SVD as I understand it can take a lower amount compared to the vamo. Some people have said theirs have gone as low as 1.0 compared to the 1.3 innokin state. I just want to get started into dripping at the moment and will, if I take to it get a mechanical mod. Also as the trident is capable of dual coils and me using a SVD (non mechanical), would it be easier and more beneficial to only make a single coil. My thought are 6 coil wraps should create around 1.2 so if I was to do 2 coils the same amount of wraps the reading would be .6 so my SVD would not fire. Is it possible to use both coils on the SVD and if so how would I do it?

Thanks coalyard, just tried that link.
Answering my own question on 2 coils, it states if the coil diameter is 4mm, to reach a target of 1.3, I would need to do 11 wraps. Does this sound right? In all the videos I have watched, I have never seen more than 8. Would it be easier as stated to stick to one coil on the SVD?

The resistance of your coil is determined by 2 things. First is diameter of your wire. The larger your wire diameter the lower the resistance. Just remember that the lower the gauge of wire the larger the diameter. Second thing that determines resistance is the length of the wire. The longer the wire, the higher the resistance is. Technically speaking, the number of coils doesn't determine the resistance except in the fact, that the more coils you put in a given distance, the longer you make the wire.

I suppose you could do one coil, I haven't tried it yet with my Scar. If I do, I am guessing I will plug the air hole that isn't over the single coil. I am vvaping my RDA on a VTR, which can fire down to .5ohm. I am using (2) 30ga microcoils @1ohm. The 11 wraps on 4mm with 28ga sounds about right. You might want to get some 30ga. I used 10 wraps for each coil on a 16ga needle (roughly 5/64"), 2 ohms per coil, 1 ohm in parallel. Good luck!

Trident V2 is a great atomizer, it's on my to buy list, I have a decent clone of the V1, but want a genuine V2.

Anyways, the best thing about this atomizer is that you can use single and dual coils, with adjustable airflow for both configurations.

Anyone just starting in RBA's should stick with single coils, until you can get consistant coils and builds, which comes with practice and with time. To do a dual coil, both coils need to be the same resistance and the same distance from the posts, or your never get them to heat evenly, causing one to burn your cotton and the other to lag. Like stated above, practice building around 1.5 consistently for a while, play with your wattage and get a feel for what you like. I vape single coils all the time and enjoy them immensly. No need to jump into dual coils yet, practice and you'll reap the rewards of a good build and dripping on your own creation.

As said, practice building consistent single coils on your Trident, you may be completely satisfied with the results (as I am with my IGO's and Patriot, etc.). I see no need for dual coils on these devices (for MY wants/needs).

My new favorite is a single 28 gauge twisted (chuck a doubled over 28 gauge Kanthal in the drill and twist it up) coil with 8 wraps around a toothpick, for .8 ohms....with a small chunk of organic cotton, on my Nemesis. Sony VTC4 batteries. PLENTY of vapor and great flavor with all my juices. More wraps would allow more resistance for use with my VV/VW devices.

Test your coils with a good meter, then test 'em again....be safe!

Ok, so recieved my goodies today, already built with 2 coils at 5 wraps each. The reading was 1.7. gave it a go and was not amazed although the juice did taste different, better or not i couldnt decide. However the whole point of me buying this was for me to have a go at building. So straight away, ripped out the coils and set to work at building my own single coil. I did so and my reading was 1.0. gave it ago and it worked fine, fired up correctly and again juice different but not over impressed. one thing I noticed that the clouds of vapour I thought i would get were not there. ok it was a little more than normal but not by much. Am i expecting too much? or am i doing something wrong? I know its down to the content of VG in the juice but is this the only factor?
