High there after problems with my aerotank v2 running on a itaste clk1280
I was using a 1.8ohm dual kangertech coil

At 3.8 volt it wasnt popping or crackling the coil and basically very much doubt it was firing the coil right up if that makes sense. Inconsistent vapour from one hit to the next. Flavour of vape diminishing after a few vapes may as well be flavourless

At 4.5 volt it sounded like the coil was firing up right. But the liquid taste a fraction burnt

So was in a no win situation. And yes i changed coils 5 times from different batches.

I am now running a 1ohm dual kangertech coil on 3.8 volts.. the coil is firing up lovely creating good vapour and good flavour no matter how long i vape for and how many times i lug.

It works fine even at 4.5 volts no slightly burnt liquid consistent vapour

I guess what im trying to say is what is the problem with 1.8 coil
And is it safe to low ohm high voltage vape?

Battery spec are as follows
Max out current 3.5a
Max out wattage 15w
Clearomizer resistance 1.2 ohm min 2.50 ohm reccomended
Short circuit protection 0.6+/-0.2 ohm

I just bought the nautilius mini tank as well today and that has the same at 3.8 volt its like sucking a golfball through a house pipe till i turn the voltage up to 4.5 but then it is slighly burning the liquid not to much just destroys flavour slightly it is running on the stock 1.8ohm bvc coil

So in essence my battery fully charged will not fire 1.8 ohms at 3.8 volts to a nice satisfactory vape. When i increase voltage it midly burns the liquid

Is low ohm high voltage ok what is the worst that can happen or do my needs require better performance equipment? Saying that i have had better vapes off 15 pound starter kits until i put i a lower ratio coil

Your CLK's 3.5A limit is why your 1ohm coil fires fine when it's set at 3.8V or 4.5V, regardless of what you set it for it's going to fire it at 3.5V 12.25W at 3.5A, it can't do anything else as it's at it's limit. What that doesn't explain is why your 1.8ohm coils can't handle 4.5V as that would only be 11.25W, maybe a dodgy batch of coils but again, that doesn't explain why the Nautilus 1.8ohm coil can't handle it either, they should be fine at that. Have your tried it somewhere in between 3.8V and 4.5V? 4.3V would give you 10.27W, should be a reasonable vape, and 4V should give you 8.89W, getting pretty low but still not too bad if the air is set up to suit. Your 3.8V would only be giving you just over 8W but still if you tighten the air down to suit you should still get a reasonable vape and some flavour to go with it. Not saying it's right just if it's the only way you can get a vape without burning you juice it's better than nothing while you work out what going wrong. Be careful going to low resistance on your CLK too, your already 0.2ohm below the lowest recommended, it could be that your CLK has a problem and firing low resistance coils won't be doing it any favours. If you think your CLK is fine and you like the aerotank have a look into the naturevape coils, a very worthy upgrade.

OK So I think you are getting too far ahead of yourself here, confusing yourself with numbers you don't completely understand.

3.8v into a 1.8 ohm coil gives a wattage of 8.02, which is fairly low. 4.5v into a 1.8 ohm coil is 11.25w. You wouldnt get much noise at all from 8w most likely a gentle hissing. 11.25 would make more noise and might give you the odd pop.

The taste and vapour problem is less likely to be about voltage and more about your juice and vaping style. The higher resistance coils are much easier to flood and far less tolerant of poor wicking than the lower resistances due to the speed with which they heat and cool.

What you have failed to realise is that at 1ohm you are puhing your battery beyond it's limits - 3.8v into a 1 ohm coil theoretically gives 14.44 watts but it's exceeding the batteries amp limit as it will be running at 3.8a. This is a bad thing, over taking the battery like that can result in it venting - basically it will explode.

Since you are running what is basically a regulated mod the device may well be limiting it's output so you could actually only be getting 12.25w regardless of the setting, certainly taking it to 3.9v would exceed the 15w limit.

I think your problem is likely to be juice or wicking related, you havent told us what juice you are using? what's it's PG/VG ratio?

The other thing is that depending on how you have the Aerotank set if you're using a thin juice you may be drawing too much air or you may be drawing too hard on the tank and flooding the coil, reduce the airflow to near the minimum level and take slow gentle draws - "Lugging" on it will just flood it and you'll end up with poor vapour and gurgling or leaking from the airholes. As for the slightly burnt taste thats either due to firing too long while not drawing or you've got the problem at the other end of the scale that if you are using a really thick juice it simply may not be wicking into the coil fast enough. Again this can be caused by too much airflow - you do need some suction on the tank to create the negative pressure that draws juice from the tank to the coil via the wick...

Thankyou for taking the time out to read through my problems
And offer feedback... do with the spec of the battery in essence i should have it on 4.3 volts and above to produce a good amount of power to the coil

My ratio of liquid goes from pg70/30 to vg 60/40
Mainly pg high liquids only the occasional gourmet i buy is a higher vg

Anyway i have my 1.0 ohm coil in and one person says its fine the other says my battery will blow... erm im worried now

I do have a 1.2 ohm coil will it be safe to run that coil on all voltages?

Also will the 1ohm really explode my battery?

Please help

 

[lucas1981]

It would be handy to know the figures for 1.2 ohm and a 1.5 ohm coil..

How do you work all this out? As i have vv of 3.5 , 3.8, 4.0, 4.3, 4.5, 4.8 , 5.0

So if my max wattage is 15 watts and 3.5 a then what coil would i need to see a nice vape at 3.8 - 4.0 volts

Is it dangerous running 1ohm coil at 3.5 volts?

There are amp draw calculators on the Internet or apps for phones which may be useful for you. You put in the resistance of the coil and either the wattage or voltage you are using and it calculates the amp draw on the battery. In your case you would put in the resistance of coil and your selected voltage and it would tell you the amp draw and the wattage being supplied. Just make sure you are below the 3.5a limit.
