Mesh\Wrap help?

[Dr33m]

I'm sure it is here somewhere and if someone could direct me I would appreciate it. I am looking for a guide or advice on mesh/wire type and wrap counts for rebuildables. Also, "twisted" coils? Why? Is there a benefit to it?

Thanks in advance!

Here's a link to the rba sub-forum - Rebuildable Atomizer Systems

There's a few threads going there on mesh/wire type. Hope that helps.

Tons of YouTube videos also that are very helpful. If you are new to rbas or genesis style attys do your homework on twisted coil. You def want an ohm meter to read your coils. By twisting coil it halfs the resistance and can be dangerous if using a mechanical mod. Running to low ohms can be bad for batteries. Good luck and vape safe!

Hi, SIX3SIX, i'm zero at electrics, can you explain it?
I'm always thought that lower res is better for the battery as it drains slower and needs not so often to charge.
But i've heard something abot watts and stuff like that, so is it really better to make more res on coils to sve the batteries?

Hi, quick question - with most rebuildables, I see guys making their coils at 1.3-1.5 ohms on VV devices. Is that range more desirable than say a 2.5 or 3 ohm coil?

Google ohms law.

High resistance is like water through a garden hose.
Low resistance is like water through a fire hose.
Think of a battery as a water vessel.
A battery has a set capacity. If you empty a water vessel with a garden hose it will take longer with a garden hose vs a fire hose.

Yeah, that i can understand, but i use higher resistance i should also raise voltage.
If I make a coil with 1.5 ohms I'll use 3.5 volts.
If I make a coil with 2.5 ohms I'll use 4.5 volts.
In which case it'll be better for battery?

A lot depends on your battery. If you are using AW IMR batteries they should be fine. They are made for use in high drain devices. Different batteries have different discharge ratings ( c rating ).
What mod are you using if you don't mind me asking?

Your battery has an amp draw limit for constant and burst rates. For example if a battery has a capacity of 1100mah ( 1.1 amp hours) and has a c rating of 10c ( 1.1A X 10= 10.1A ) Most manufactures will supply a c rating stating the maximum safe continuous discharge current rate. Others will state their maximum safe burst current rate. Most often the burst current is equivalent to 2x the continuous current rating. Most mods don't pull more than a 5 amp draw max. Mechanical mods being the exception.

The following links are a couple popular IMR battery size specs.

Thanks for the info, TechJ.
I have a ProVari with AW IMR 18650 3.7V 1600mAh. When I used it with Bulli Smoker atomizer with res 1.7 it lasted for me for 1 day, when with res 2.3 it lasted significantly lesser time.

Nice. I have a provari mini with the extension. When I was using 1.8 ohm vivi novas I was getting a day out of an 18490. Since I've switched to a Zen Z-Atty-Pro which I setup with 1.5-2.5ohm coils I get about 5-6 solid hours now. The main reason for this is I vape at much higher wattages than I could with the vivi novas. I'm often pushing the 2.5 amp limit. The equals a much higher power consumption.

VxV/R=W

Sorry, TechJ for a long absence, I was in hospital with my child.
So, what's the second V in formula?
First V is that i set on ProVari (f.e. 4.0) then multiply by second V (which?) divide for Res. (f.e. 2 ohm) and get watts. What it gives me if I know watts? Should i know amps?
Generally, what's tastes better, if there any difference, low ohms and low volts, or high ohms and high volts?

 

[TechJ]

Voltage squared or ( volts x volts /divided by resistance = watts

Generally running low resistance and voltages is similar to running high resistance and high volts.
The difference comes down to amperage. It takes more amps to make watts with low resistance / voltage than using high resistance/ volts.

If you google watt calculator you can find an online app that you can input your volts and resistance and it will give you your watts and amps. Play with it a bit you will see what I'm talking about.

I hope all is well with the kid. I'm a parent too. Nothing scarier than a sick or hurt kid.
