Mech Mods - Where Am I Going Wrong??

[bkkkpewsey]

Checking the voltage on a mech mod using a multimeter at the 510 connector will only tell you the battery voltage NOT the volt drop.
You need to use a tankometer or check the voltage at the atties terminals under load

It will tell you the voltage drop within the mod (contacts/tube/switch) when you subtract the reading from that across the battery itself and while an in-line voltmeter would be ideal, not everyone has one which is why I suggested a multimeter.

fred, yes, vamo in RMS... but using the same tanks etc the mech doesn't come close hence my concerns......

@yinyang, protank @ 2.1ohms, only use 3.4-ish volts on the vamo hence expecting the mech to vape similar, but it just doesn't

If you lower your resistance to between 1 and 1.5 ohms your mech will perform much better.  My experience of mechs is that anything above around 1.6 is better in a vv/vw mod

I am afraid you signature is correct as in this case you are wrong.
A bit of understanding of Ohm's Law wouldn't go amiss e.g. V(drop)= IxR
As a multimeter draws virtually no current (I) - then there will be virtually no volt drop.
As I said before to measure voltage drop in any mech mod, it must be under load.

no need to be like that people are trying to help somone no need for the attitude at all

Thank you for that explanation bkkkpewsey - I am always ready to be educated.

I wouldn't use a UDT-L mod...

Breaks too easily

Could I as a daft question ?....
With my old A level physics being just a fading memory of my ancient past I was trying to make sense of the above convo ....
Now surely the difference between the voltage of the battery and the voltage at the 510! Connector is the voltage drop... I don't understand why putting the battery under load will measure anything other than the difference between the battery and the load ... What we're trying to ascertain is how much our super shiny battery holders lose in transmitting power to our coils ... Isn't it ?..... Or am I totally wrong and need to go back to school .. ?
