Coil and Voltage advice

[Davecobweb]

Hi,
I've been vaping for 1 year now and have recently purchased a Vision Spinner 2 to try out and see if it's any better than a 'standard' battery.
With the battery im using a KangerTech Unitank with 2.2ohm coils which I purchased from Amazon.
All is good up to 3.8v, but when I turn it up to 4.3v I get a horrible taste in the mouth so have to turn it back down.
I understand it could be the juice I'm using (Pear Fresh from LT ecigs 12mg) but I have a feeling it has something to do with the coil.

so my question is, should I be using a lower rated coil?
I am more interested in flavour rather than smoke!

Thanks
Dave.

Hang in there Dave.

4.3v is a little too much for a Kanger... let me revisit the thread later

Welcome.

No, it's not the juice.... I've used LT liquids at crazy-looney-tunes power.

Thanks for the response djsvapour.
Sounds like I might have to use my 3 unitanks for my standard battery and maybe treat myself to something else for the spinner?

You should be able to use voltages between 3.8 and 4.3. That's a pretty wide range to only be able to choose from. I'd start at 3.8 and incrementally turn it up. You'll probably find your sweet spot around 4.0 or 4.1

I loved my Vision Spinner II and used it with an Aspire CE5-S with 2.1 ohm BDCs. I could vape it at 4.8 and tasted fine. I'm guessing it is the coil you are using...too low of an ohm rating for the higher voltage. Or it could just be your taste. Everyone has a sweet spot.

The point of VV and VW is to let you adjust the vape to your taste, regardless of the coil value (within the limits of the device, of course.) different flavors will taste best at different power settings. There's no "rule" on what you set other than if it's good tasting to you.

Air flow on the Unitank isn't real big, so that will limit the max power you can apply. Unfortunately, the air flow control bases won't work on them.

But if you're getting a good vape at a lower voltage setting, I don't see a need to change coil value. Staying in the 2.2 - 2.4 range will give you greater adjustment potential than going to a 1.8.

I've heard that fruit flavor juices usually taste better at lower voltages where tobacco flavors can use higher voltages.

Kangers don't like high volts/watts. They'll burn the juice that way. I have 14 of them. Aspires do that pretty well, as do the RBA/RTAs

I thought the point of an adjustable battery was so you could adjust it to find that sweet spot whilst vaping and so bring out the flavour of the juice. If I'm keeping the setting around the same as a standard battery then is there any point in having an adjustable one?

A standard battery's voltage declines from the first puff, whereas an adjustable will or should keep it stable. But yes, the notion is to find the best setting for you, it's not about the numbers.

Indeed, and you do that by varying the power to the coil for each flavor and mix. Pre-made coils may or may not be the value advertised / labeled, so with a fixed voltage the power will change depending on the resistance. And if a flavor wants a different power, you need to calculate the coil value you need...

Or, just control the voltage, either with VV, and you tweak as needed, or VW and let the elex do the work controlling voltage.

Quite true, but most of the ego types have circuits that will boost the voltage, keeping them relatively stable until somewhere around 3.2 - some better at it than others, probably.

4.3v should be okay with a 2.2 ohm coil (the power would be 8.4 watts, which is at the top end but should be okay). But here's the thing - sometimes these coils don't come out exactly as per the spec. Have you measured its resistance?

With only a 10% error (ie. in reality it's a 2.0 ohm coil) the power delivered at 4.3v would be 9.25watts. That's now in burning territory for a kanger coil. My advice would be to vape this coil around 3.8v.

Another alternative, and what I do with kanger coils, is re-build them with a cotton wick. I think cotton wicks better, and so gives better taste delivery. And if the cotton gets burnt, I just slip it out and re-wick with new cotton. The dual coil heads I re-build with a single (oval) coil to allow easy wick replacement. I have done dual coil re-builds with silica wick, but find the performance of single coil, cotton-wicked to be better. I have not yet tried a dual coil cotton re-build... as it would be hard to replace the wicks (because of the smaller coil diameter, and the spacer wick between the coils) but I might give it a go one of these days.

Thanks for for the info Doc.
Im not into rebuilding coils, I'm more of a plug n play man. And as for measuring resistance, I wouldn't know where to start!

As I purchased x10 2.2ohm coils before I purchased the vv battery, I'll use these with the Unitank on the standard battery.
Ive come to the conclusion (right or wrong) that I need to purchase something that has a variable air flow and can handle all settings on the Vision Spinner 2.
Any suggestions from anyone?

Hi Dave, your Unitank is using Kanger single -coil atties, which means that your 2.2Ω coil at 4.3 volts generates 8.4 watts--which is just outside the Kanger recommended range of 5-7.5 watts (per single coil). I suggest you don't go above 3.9volts with that coil.

Should you be using a lower rated coil: No, there's nothing wrong with the coil.
Your coil works best at around a certain voltage like any other coil.

If you use a lower ohm (single) coil of the same wire gauge (and you won't know what wire guage you're getting when you buy a coil head), it will work at a lower voltage.
If you use a "lower ohm" dual coil consisting of the same coil you have now (2.2 ohm) but there's two of them which works out to a 1.1 ohm dual coil, it will work at the same 3.8 volts, but perform twice as well if you have the battery power feed those two coils.

If you use a lower gauge coil (thicker wire) of the same 2.2 ohms, it's going to be able to handle alot more volts than the thinner wire coil.

Yes, the point of an adjustable battery is so you could adjust to find the sweet spot.

The sweet spot will vary with the coil, and the juice; it can also vary over time as you vape on the same coil head and the wicking wicks faster over time (also called leaking); if you have adjustable airflow, that will also affect things.

The vv battery also regulates the voltage, holding it constant; there are some 'standard' batteries which do not do that; they drop off in voltage while you are using them; then there are also some 'standard' batteries which are actually regulated to usually either 3.7 volts, or there are some older ones regulated at 3.3 volts.

You might want to look at the Kanger PT2 and a "replacement" air flow control base. that way, you can use the coils you already have with it. While there are many others that come with air flow control, once you move to dual coils, you'll have to lay in a supply of coils for them.(There are a few others that will also take the single bottom coils for your Unitank. The Davide Glassomizer is one, even though current models come with dual coils, it's an easy change - but likely need the replacement air flow base as well. Haven't looked at the new ones in some time, and it seems the offerings change daily!)
