I've not been on the forum for a while, I come back to find a rather odd comment From ?.....very strange. Anyway I've been busy recently extending to juice offering And setting up a new tasting station   |

what kind of wire are you using?

I use pliers to tighten the internal contact screw. if you unlock the switch
then push the button you should get enough sticking out to get hold of the end.
If its not done up tight then it works loose when you swap batteries.

I was just worried that people might read your comment and interpret it as safe
to do their AMP calculation based on the measured drop voltage, when its considerably safer
to use the fully charged battery voltage.
The relatively small additional resistances do as you say, add a level of headroom.
I have always thought load tests as a measure of mod performance were a pointless
activity, unless you are just going to use them to calculate the actual performance
of you mod and look at the device resistance. But the vaping reviewers never do the maths.

I think this is about where the voltage drop is occurring, internal to the battery
Is different from external in the mod.
My experience of mechs tells me by far the largest drop is caused by dirty switches.

By deducting the voltage drop, you are effectively saying that the battery didn't have to do that work.

I still say voltage drop under load has no effect on what you battery is being asked to do.
Take a 4.20 charged battery, measure the voltage drop at the coil at 0.42
That's a 10% drop.
As we know voltages are shared between resistances we now know that
10% of the voltage has been consumed elsewhere, mostly the switch.
So if we know the coil resistance is 1 ohm we can now calculate the switch resistance
To be 0.1ohms. The battery remains at 4.2 volts and is splitting it's voltage across
A combined resistance of 1.1 ohms.
I agree that voltage drop is a way you can understand what work you asking of the cell
But it the drop load voltage is dangerous to use to calculate your safe amp limit.

Thats Good Work Ripshod. Like that you are listing The Power and resistance capabilities of each battery. Am i right in saying you've accounted for some 'headroom' so that the battery is not stressing to much? I have for regulated mods. I don't think headroom for mechs is too important with the batteries listed so far - as soon as ypu fire a low ohm coil the battery's volts will immediately drop, kind of giving it's own headroom. You have a concern? Better to discuss it here  With Mech mods the measured voltage under load should not be used to calculate the amps being pulled. The battery still puts out it's full voltage, you are only seeing the volts that get used by the coil. he remaining volts have been consumed by resistances in the mod, normally the switch. The lower the coil resistance the higher the loss to the other resistances, it works as a ratio. The point is that you should measure the voltage at the battery, not under load, as that is what the battery will dispense, although you will not see all of it at a single point inthe circuit. |

This coming Friday (29th may) demonstrations have been planned throughout Europe. Here in the UK there are two, one in Swansea and the other London.
I decided to organise the London one because, when news begins to spread, that European vapers are protesting, and our government decide to look out the window, what will they think if there is no one there!
Will what they see persuade them that we care, that this is an important issue. That they should resist the whispers in their ear from Big Tobacco, pharma companies or even the madmen in tobacco control.
This is our opportunity to prove that we are real,people and we DO CARE.
Just doing nothing at this point could be disastrous.

If we say 20 a day average, at £9 a pack, that's £3613,500,000 in lost revenue per year
Just from those that have fully switched.
That might be why there is a little resistance to ecigs.

The headline figure shows 2.6 million users of ecigs in the UK now.
Many are lamenting that this number should have been higher. Yes, if the press hadn't rushed to publish misleading headlines, that might have been higher.
But look a bit closer, there are now 500,000 new users of ecigs in the last 12 months.
Not a number to be sniffed at. The really exciting number though is how many new non smokers:
400,000
That's an astronomical number of new non smokers in just 12 months.
There has never been anything close to that before. It's a number that just blows my mind, 400,000 people have successfully quit smoking since this time last year.
To put it another way: 80% of the rise in ecig users have successfully quit in the last 365 days.
