Single 18350 question. Seeking pro advice.

[finnman1]

Hi all!

I have a V2 one state away in the mail and should be receiving it either today or tomorrow. With it, I will be using Efest IMR 18350 batteries single stacked in the "Mini" configuration, exclusively. I will be juicing with Vivi Novas containing 2.8 Ohm coils. This will be my first E-Cig!

I do not pretend to be electronically inclined to say the least. I did not get A's in Science class as I was usually paying attention to chasing tail instead. I humbly come before you in asking advice on recommended settings using the above 'setup' with one 18350 as I do not plan to put it in lightsabre mode.

From what I understand, there are two ways to adjust the mod. Via Wattage, and via voltage. In addition to this, there are two settings. One is "RMS"? and the other is "Standard"? Okay, I do not wish to blow up my device, or my face, or the batteries by playing around too much, but I'd like to be able to 'play around' with the power when trying out new flavors.

Would those familiar with the device be willing to provide a good 'operating range' for the 2.8 Ohm coil and single 18350? I'd like to know if I should switch to RMS mode. What setting ranges to stick to and avoid, if so. I presume it would be best to run it in Wattage mode as it will be calculating the voltage for me automatically, yes? I plan to learn more about this device, however, I respectfully ask for advice on general ranges to keep it in; including wattage for the 2.8 Ohm coil.

I thank you for your time in advance,

Chris

The two modes are NO1-AVG and NO2 - RMS. Rms is the more accurate of the two so just hold the + button for 10 seconds till you see no2 and your set. Then there is a voltage or wattage mode. You can use either one to find your desired vape.. If the vivi can keep up with wicking at a high power level you shouldn't burn it out. I personally never go over 9w and usually vape between 6-8 depending on the juice. If you watch a review of the vamo on YouTube pbusardo has a good one he explains all the functions in detail.

Enjoy your new toy any more questions just ask

I'd go ahead and put it into power mode as it is easier and you are less likely to burn out your atomizer/cartomizer/clearomizer (ViVi Nova in your case) if you change resistances (different heads in the Nova).
To set the power, start out low at around 5 watts, try it, kick it up a bit to 5.5, take another couple of hits, and keep going. If it starts to taste too harsh or too warm, back it down until you get to the best power (flavor, warmth, and vapor to your liking) for your Nova and the juice your vaping. Also, if it starts to taste burnt as your raising the power, you're burning the juice and you need to back it down. Don't forget that you will need to tip the Nova fairly often to keep the tops of the wicks wet and it's best to vape them at near horizontal to also aid in wicking.

You will probably find that you will end up hovering in the same wattage range with most juices but there may be some odd ones that just need more heat or, on the other end, taste really bad with more heat.

As for the device, it is designed with a current limiter in it so you won't hurt it by going too high on the power, but you can burn your Nova (fortunately, the heads are replaceable in such a case). The greatest advantage to the larger batteries is that they last longer. An 18650 is 3.7 volts nominal just like an 18350 but has 2 or more times the storage capacity so it will last twice as long or longer. All other things being the same, a larger battery will also have a greater current capacity as a rule but, if you stay below 9 watts, that probably won't come into play.

You stated that you were going to use 18350's stacked. "Stacked" indicates that you would be placing 2 batteries into the mod and the Vamo only takes a single battery; one 18350 in "mini" mode or one 18650 in standard mode. I'm not a fan of stacking batteries anyway as increases the chance of having a battery failure but, in the Vamo, you should never do it. It is the Vamo VV you're getting, right?

Gongrats on your first e-cig!

That is incorrect. Using a pair of 18350 batteries (stacked) will allow the Vamo to run at it's best.

Actually, I stated that I will be using it with one 18350

Thanks for the Phil B link. I had watched it, but he goes into detail about stacked 350s and single 650. I don't believe he provides data for the 350.

DizGrizz, when you stated 'put it in power mode' 'because it's easy', are you referring to mode 01? Is the other mode kind of like "Automatic mode?"

I found this chart but if RMS will be of some advantage, i'd like to learn about it and get my money's worth. Why I say this, is because Phil B's vid looks like the wattage is .5W increments. Looking at the chart, being able to only move by .5 watts at a time, I would miss some potential settings. Wondering if RMR needs to be used.

Yes, I meant to place it in the variable power mode (press and hold "+"and"-" at the same time for 3 seconds). You are correct that you will not have quit as much adjustability using the VW mode but I doubt that you will really miss it. It's up to you, try them both and see what you think works best for ya. If you use it in VV mode, definitely use the RMS option as the AVG/Mean option gives you a number that really means very little while the RMS numbers are a much truer representation of the equivalent DC voltage at the atty.

OK, I retract the "cannot use stacked 18350 batteries" comment; my info was incorrect. However, I'm still just not a fan of stacking batts.

boo. no one helped me.

 

[finnman1]

Is there different settings in RMS mode? Thats the way I took it originally and why I had asked if there was a specific "range" i should stay within. It's interesting that they give you Watts in .5 increments, rather than .1 like the volts.


Frosting, I would look for reviews on your brand of battery and go from there. You can always buy a diff brand and compare the two. People state the elfast 18350 have no issues, with discharge rates, nor fitment inside the unit.

... Just got my VAMO today. The grey 18350 it came with, i charged. I checked the battery on the built in multimeter. It was about 4.1/4.2. Using one, in short mode has only lasted about 2 hours. The battery is now at 3.4 volts. Much advice say take it out now, or around 3.4. I've been vaping heavy, really enjoying playing with the VAMO. Is this normal?? With 900 MAH I thought even with heavy use one 18350 should last at least 4 hours before going to 3.4 volts.

Take it out when it stops working.

As far as 900mAh it's questionable if that number is accurate. Panasonic for their Li-Ions drags them down to 2.5V to determine their mAh rating. You also have to consider how these boosters actually work. For one thing the booster is not 100% efficient, so right there you are losing 10-15%. Second boosting a 3.7V battery to a higher voltage requires more amps than a simple Ohm's Law calculation at the atty would infer and to maintain/regulate the output as the battery's voltage drops the amp load increases.

I'd go ahead and put it into power mode as it is easier and you are less likely to burn out your atomizer/cartomizer/clearomizer (ViVi Nova in your case) if you change resistances (different heads in the Nova).
To set the power, start out low at around 5 watts, try it, kick it up a bit to 5.5, take another couple of hits, and keep going.

I'd start lower than that. I recommend starting at 4 watts, which is a cool vape, and just click up from there. On my Vamo, and the Zmax also, I vape anywhere between 4.5 watts to 8 watts.
If you are using a vivi nova then use the 2.4 and 2.8 ohm heads. A Vamo has plenty of punch so you don't need low ohms.
You can use 2x 18350 - but it isn't necessary to get a good vape. I use one 18350 a lot and its fine.

The Vamo will cut off when your battery is at 3.2 volts anyway, which is not over-discharged.
