Veritas Mech Build - question

[whosrandy]

Hello,

I recently got the Magma and Veritas clones from FT and loving them. Absolute steals - both extremely well made. Anyways, I am really liking my Magma at around .65 ohms on a Mech and tossed a .7-.8 ohm build on my Veritas. The Veritas vape was far too cool and weak. So, I popped it on my IPv2 and enjoy it at the following settings:

25-30 watts, 4.9v, 0.7 ohms according to my IPv2. How can I build this on a mech to achieve similar results? Thanks!

So, according to the calculator, that's 6 amps output. Does that mean with a 3.7v output (on mech), a .6 ohm resistance will result in similar power? 6.17 Amps but only 22.82 watts. Is this the same? Or do I need the wattage to be the same?

A mechanical mods power, wattage, and the temperature of the vapor relies on 3 things:

1. Battery voltage, most if not all batteries used in mechanicals charge up to 4.2v and usually run down to 3.5v and then recharged.

2. Surface area of the coil, more surface area=larger vaporization area and more heat

3. Resistance of the coil, lower ohms = more vapor but requires more power.

Also, what batteries do you use in your mechanical?

 

[whosrandy]

Okay. 4.2v - cool. Thought it was 3.7v for some reason. Efest Purple IMR 18650 2500mah are my batteries. Also, VTC4's.

I understand the basics of creating vapor. I just want to know how to do the math to have a similar power output as my settings above.

Use any of the available online Ohm's Law calculators to do the math. I use this one:

Watts - volts - amps - ohms conversion calculator

Enter your voltage and resistance to determine how much power you are making and how much current is being drawn from the battery.

With a freshly charged battery and a .7ohm build in your Veritas, you'll be making about 25W as shown below. This does not account for voltage drop.

For the sake of argument, let's assume .5V of voltage drop. You are now pushing about 19.5W.

I'd try a .4-.5 build and see how that works for you. With the batteries you are using those resistances will be no problem. Even a .25ohm build on a full charge (and assuming no voltage drop) is only going to pull ~17A out of the battery.

I personally build a single horizontal 0.5-0.6 ohm coil on my Veritas.

It works great and produces great flavour.

The clouds are decent at best but the Veritas is not really made for vapour.

i run a 24 or 26ga single vert. parallel 5 wrap on 3/32 i dubbed "third leg parallel" (each neg. gets a leg) its beast

Ohms Law calc

3.7 v @ 0.6 ohm = 6.17 amps @ 22.82 watts

I'd say for somewhere close to 30w go for the 0.4-0.5 area. Depending on the mech and voltage drop that should put you right in the ballpark.

 

[whosrandy]

Thanks for the help guys.

 

[whosrandy]

So am I trying to achieve the same amp or watt output or both?

The wattage output is going to give you the vapor, flavor, and throat hit and is how we generally measure coils (and many other resistor based circuits in life). To get the same vape quality, match the watts. The amps are telling us how much current is closing and realistically how much stress is being put on the batteries. That stress is what heats up the battery and can cause a vent. I hope that helps at least a little bit. There is so much more information out there, but I don't know what you want to know about what.

 

[whosrandy]

You guys were spot on with the .4-.5 recommendation. Currently rocking a .4 ohm 26g twisted horizontal build.

This was my first twisted coil; what do you think? Only been 3 months since I started.

Looking good. The only thing I'd suggest to try is angling the coil a little (~45 degrees) to shorten the top leg a tad, but only if you want to lol.

Aye. I was all in at the length shown above. It started to melt the insulator so I had to push it out a bit. Will do next time.
