Nemesis mod

[guitargodd6]

I am new to mech mods and just purchased a Nemesis mod with a Nimbus rda. I watch a video on how to setup the Nemesis so I think I might have it setup right (had to make adjustments as it would not fire up because of the connections).
Have not tried building my own mod just yet. But I am not getting much vapor at all out of what was already setup in the nimbus. I get more vapor out of my VV batteries. Is there something wrong or should I just go ahead and try building my own coils?

What kind of set up came with the Nimbus? Did someone make you a custom coil or were there some pre-wrapped ones of unknown resistance in the package? Also toss your batteries on something to measure the voltage and ensure they're properly charged up past 3.7v. Some pics of the coil and nemesis setup could help as well

Hello and welcome to the forum. Glad to have you here!

If you are new to mech mods and rebuildables I highly recommend you spend some time with Baditude (one of our resident battery experts) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

Baditudes Blogs. The blogs regarding mods and rebuildables are listed below:

The coils were prewrapped and unknown resistance and don't have an ohm reader at the moment. But the battery I have is a Samsung 18650 with a Trustfire charger and it says it's charged.

Depending on your VV device it should tell you the ohm load of your coil as well. HOWEVER that being said, for the love of *insert favourite deity* don't build coils without a proper ohm reader or at the very least a good multimeter. Also, I would suggest you never use a coil you don't 100% know the resistance of, in any mechanical mod, that's asking for some potentially severe issues.

If your combo was the same one I got (Nemesis/Nimbus off ebay with a skull driptip) you might find the business ends to be lacking and not proper clones at all. I'm going to buy replacement parts because how much I am unsatisfied with them. That said I like the Nemesis setup though I'm not sold on the coils that came in the Nimbus. I think mine read at 1.8 ohm. Does your top look right? I mean like other Nemesis seen in vids?

I'm using a RBA with a ~1 ohm coil on it with cotton wick and it puts out as much as my Nautilus on my MVP. I really think it's the pre-built coil. Hope I'm a little helpful. Cheers!

 

[Neolithium]

Safety stuff aside, I noticed I NEEDED to set my Nemi clone up a certain way or it wouldn't fire properly. I'd put the RTA or RDA on my top cap with the pin screwed quite a bit out, once the atty was on, I would screw the center pin back in until it made contact with the atty. Fired my battery in (18650) and screwed the button on (It's center pin was loose and high, so that was screwed back down all the way by myself as well. The Nemi fires very well now (Not counting the spring that I'm waiting on my magnets for, of course).

Still, do please spend some time with battery safety as well as coil information and ohms law before playing with mechanicals. I initially thought it wasn't too serious but there's enough YouTube vids with catastrophic failures that made me spend a few hours reading, and it was well worth it IMO. Now I can comfortably use my mech without having any nagging doubts in the back of my head that my coil will blow part of my face off.

I would goto your local BM shop and ask them to build you a coil/coils for your nimbus. Let them know your new to the mech/rda set up. If they are a good shop they should build you a safe build to start out with. Pay attention to what they are doing cause you will see it's not that hard to do. I suggest you get an ohm reader and a spare battery. I use purple efest 30 or 20 amp but everybody has mixed views about batteries so go with what the shop got. Pick up a couple yards of 30g or 28g wire so you can experiment and build some of your own coils. Grab some wicking material too. I use cotton bacon or organic cotton for my rda's it seems to give off the best flavor and essentially that's what your looking for. If you don't have a B/M shop close use the ecf forums. These people are here to help anyway they can. I have been reading threads for the last couple days straight. Good luck and vape on!

I'm not a fan of the hate on efest batteries right now, HOWEVER I don't go for elegant sub ohm builds, at MOST mine will be around 0.8, which is more than safe for a 10amp battery, which their "35 Amp" can handle, even though they're MAX 20amp continuous draw. I also have a multimeter I take to work with me so when my batteries hit 3.7 I immediately stop using them and move to a freshly charged one that is in a PROPER case (Don't carry spares in a pocket loose), my 18650's last me a day at work though, only at home can I really chain vape.

guitargodd- I'd also suggest you make it clear to any B&M that you want to stay above 1ohm for the time being to get comfortable with things, I can easily get great flavour on 1.0 - 1.3 ohm and not care about lowering it in the least, it also saves me battery life.

I guess I'll try building new coils. Can someone tell me the steps?
I know measure the battery voltage which mine is 4.2 now.
And then measure the coil ohms which the prewrapped ones I have in it now comes to 2.8.
And then I subtract 4.2 and 2.8??
I get 1.4 but what does 1.4 represent??
Forgive me lol I get easily confused when math is involved.

If your coils are 2.8 ohm, that is way too high for your mod.

ohms law: volts = current x resistance.
also watts = volts x current

so you are pulling 1.5 amps current for a total of 6.3 watts. That pathetically low. You need to build some coils at least below 1 ohm, preferably around .5 to start. And make sure your samsung is a 25R or similar 20A+ continuous battery.

 

[guitargodd6]

What are the steps to making sure I have the right setup?
I have Samsung INR18650-25R and a website I found says it can handle down to 0.22Ohms

Yes, 25R will work great for that. As I mentioned before, if you measured your coils at 2.8, that is too high. You need to drop that resistance a lot.

Do you get more vapor out of your VV batteries with the same nimbus? If so then at what voltage?
By vv batteries, to you mean twist/spinner types?

When you have a mech, you need to build your coil to work with standard battery voltage (3.7 volts); unless you get a dropin kick module for your mech.

 

[guitargodd6]

So is all I need to know max Ohms of my battery (0.22Ohms)
And the Ohms of my RDA?
And if it's above 0.22 it's good?

 

[guitargodd6]

Yea i have a itaste MVP2.0 that puts out way more vapor than this Nemesis. And I usually keep it at 4.2Volts or 8.5Watts.

Steps:
0: GET A MULTIMETER so you can check volts and ohms.
1: buy some kanthal; I suggest a roll of 30 gauge.
Better yet you might try a few feet each of 32, 30, and 28 gauge.
2: wrap a simple coil: 2mm diameter, about 7 wraps; that should give you somewhere between 1 and 2 ohms depending on what gauge wire you used.
3: install coil and dryburn it by pulsing the power.
4: wick the coil.
5: juice up the wick.


Your 2.8 ohm coil is probably 34 gauge; or maybe there's 2 coils in there and one isn't connected properly.

 

[Neolithium]

I would not recommend starting off at 0.22, that's ridiculously low for someone new to dealing with mechanical mods. 0.75 - 1.4 is well within the safe zone and should have no issues still getting you good vapor. Get some experience in that range first, and then go from there. And once again, get some quality gear to check your resistance. For mechanicals there's several things you should absolutely not skimp on:

Quality Batteries (Which you already have)
Quality meter to check resistance as well as your battery voltage remaining, so you don't run them down too low.

 

[DaveSignal]

Well I wouldn't recommend .22 for a first build either, but I also wouldn't recommend 30g or higher resistance wire for an RDA build. 28g or even 26g are easier to work with, cover much more surface area, and are great for beginner-level builds. Other than that, edyle already listed the steps to building a coil, but there are plenty of videos and tutorials available on youtube.

6 wraps of 26g around 5/64 will get you around .6 ohm for a single coil. 26g is about exactly .1 ohm for each wrap around 5/64. This will pull somewhere below 30 watts from your mod at full battery charge. If you decide to add dual coils (both identical at 6 wraps), you are still at .3, within the safe range for your battery... and you double your watts to just below 60. Its an RDA. And a mech mod. This what these things are made for.

Please slow your roll a bit. get your ohm meter and re read Susan's post. don't build anything until you understand ohms law.
safety first is a life style.
