Aspire Subohm battery - safe at 1.6ohm?

[drjaking]

Hi,

Can anyone tell me if it is safe to use the Aspire sub ohm battery with a 1.6ohm coil in a nautilus Mini? Aspire say that the battery is only usable for coils up to 1ohm, and that it will supply too many watts, damaging the 1.6 coil. But I thought the only thing determining how much power a coil uses is the voltage and the resistance. In other words any battery at 4.2v will push the same current. Just cos the subohm battery (it's essentially a mechanical mod) CAN support 40W doesn't mean it will force a coil to draw more current. The Nautilus Mini coils are fine at 4.2V, so should be fine on the subohm battery. Or am I missing something?

Not sure if it damages the coil but a friend used my sub ohm battery to power his Nautilus Mini. It worked but he said that he wasn't get much vapor out of it

Welcome to ECF, drjaking...

You are correct, a mech will apply wattage based on net resistance and voltage, while a regulated mod - if capable - can "force" wattage above Ohm's law formula values... handy to compensate for less than optimal builds or obtain a higher heat flux value (coil radiant temperature).

I've not really looked too deeply into the specifics of the Aspire Sub-ohm battery (and so we may both be, "missing something" )... but as I understand it from a casual read, the 18650 version is essentially a battery with a wired in function switch and no specific form of regulation... and so operates following Ohm's law.
If that's the case, then it will discharge 11 watts at 4.2 volts.

Cheers

The reason it says good up to one ohm is because on a mechanical battery going above 1 is usually a weak vapor, it will work but the higher you go above 1 the weaker the vapor will be

There's 2 options for Sub-ohm batteries at Aspire, one comes with a fixed battery and the other is basically a mech mod with some basic protection. Both will give you the same experience as vaping on a mech mod, I will even go further and say the fixed battery is a 18650 with enough amp drain to vape your sub-ohm coil safely.

If you plan to use a 1.8 ohms coil, the battery will discharge quite fast but I do believe it will give you a satisfying vape.

Then why does the 2 ohm coil in these work so well??????

It all depends on what the coils are in. Aspire just naturally assumes you will be using an Aspire Atlantis tank is all.
AND, their right, anything above about 1 ohm would be an anemic vape in an Aspire tank with that battery.

Thanks for all the responses.

Aspire are misinforming then, they say it will push too many watts and damage the coil.

Odd...

Aspire state in their literature to use coils 0.3-1.0ohms. Why would they rule out all the users of 1.0-2.0ohm Aspire Products?

It makes no sense. If it can run and 0.9ohm coil, then why not a 1.1ohm coil?

I suspect some confusion between the "intended" coils and the reality of what it can do. Would it not protect itself anyway if you attached something unsuitable?

I'm sure they work fine but I'm willing to bet they don't run well for 9 hours like my .8-.9 ohm coils d,o even down to 3.4v I can keep vapin if i cant get a fresh cell. I don't believe a 2 ohm coil could fire effectively at that low power, but stranger things happen and I could be wrong, not the first time lol

Also like you said those tanks are designed with high power in mind

 

[drjaking]

I suspect the reason the Aspire people are saying you can't run a Nautilus on their Sub Ohm battery is to encourage people to buy more tanks. That or simply being ignorant.

I'd like to follow up a couple of points from your responses anyway.

First, the point about regulated mods being able to force more wattage. How do they do that? Is it just by automatically increasing the voltage til it reaches a set power? If not, what other electrical explanation is there?

Second, how would a 1.8 Ohm coil running at 4.2V give a more 'anemic' vape on a mech mod that is capable of up to 40W than it would on a battery with a lesser rating? Surely it will be exactly the same? I've now heard two reasons that one shouldn't use the Nautilus tank with the SubOhm battery, neither make any sense so far!

you should be fine
