New technical question.

[Davantrac]

I've got my firsts mech mods on order and a kick for safety till I get going but need some help with understanding voltage.
i know that a full battery will run 4.2v slowly dropping to about 3.5v before needing charging, that's the safety boundary I've been told. So to get my liquid to taste as I like it means building a coil to suit, I'm getting my head round that part slowly.
Now, with a vv/vw mod and the same battery how can I turn the voltage up to 6v to get the sweet spot? That's the bit that I just can't get my head around.

 

[jpcwon]

The VV/VW mod uses "buck/boost" circuitry to increse the voltage beyond the 4.2 nominal voltage of a freshly charged battery.....

[crxess]

No, the question would be - Is 6v the sweet spot?

Your entire build, from Mod/Battery choice to Atomizer type, coil build, available air flow, wicking and even your choice in E-liquid blends will ALL have an effect.
You have a lot of homework to do before your new toys arrive.

VV/VW devices Boost available power to reach their available peaks. If you ever had experience wit ha capacitor you would have a bit more understanding of Power increases, but it is a way of taking available power, collecting and distributing what is requested.

Your Kick will give you a chance to work with coils over 1.2 ohms but will need to be removed once you go below.

That's what I needed to know to vv use capacitors to boost the v. I never thought of that, similar to a 12v vehicle coil. I know I've got some learning to do and know it a lot of trial and error depending on my set up find the sweet spot. I just couldn't get my head round that voltage part. I've read up on ohms law and understand that the lower the resistance you build, the higher power you get from the same voltage. Can anyone give me good starting coil resistance for a mech mod with fully charged battery when I normally vape at 9w on a 2.2ohm factory built coil to get my sweet spot. I've been using iclear 30 coils but have a kayfun clone on order for my trials.

Anything at or below 1 ohm really shines on a mechanical device. But that doesn't mean you can't run higher resistance coils on it if you want. In that case though, you'd be better off with a Kick.

When you begin to vape coils at 1 ohm and below, you REALLY have to start paying attention to the kind of battery you're using and the amp limit of the battery..... If you exceed the amp limit of your battery, bad things can happen as there's no protection on a mech......

Try building a coil around 1.2ish ohms and see how that treats you (that's 14.7 Watts on a freshly charged battery). Then you can adjust from there. I am currently vaping a 1.3 Ohm single coil in my GP Heron and it's performing beautifully on my mechanical......

 

[Davantrac]

So approx 6 wraps of kanthal 30 on 2mm drill should give me about 1.4ohms and that should be about 12 watts. Am I getting this about right?

1:
Which kick did you get;

2:
Note, the kick goes on the top on the battery between the positive end of the battery and the atomizer head.
I do believe there are kicks that do not have reverse polarity protection. (Crazy)

3:
Try 2 ohms. With the kick.


With the kick you don't need to be too exact with the ohms; instead you just make the coil and adjust the kick.

This is the kick I've ordered ..... https://www.fasttech.com/products/1670801
I've also got an aerotank with 1.8ohm coils ordered to get safely started.

 

[VapingTurtle]

Try a 1.8Ω coil in your new Kayfun. Your battery will pretty quickly drop to 4v, and that will be about your 9 watts.

This is very helpful: Steam Engine | free vaping calculators

I've got Steam nicely bookmarked, wish there was an app for it.

What kind of phone do you have? I have an app on my Droid called "Vaper's Toolbox" which has some neat stuff in it, like coil-building calculators, ohms law calculators, etc.....pretty cool little app!

Ah! Same kick that I ordered too.

and unlike the evolv original kick, the sigelei kick seems to have reverse polarity protection:
Sigelei Kick

Use with IMR Batteries only




Features:

- Adjustable from 5W-10W

- 3.1V Battery Cut-off

- Low Resistance down to 1.0 ohms

- Short Circuit Protection

- Reverse Polarity Protection

And what mod did you order;

bottom fired mods have the risk that if the battery covering gets torn, your mod is always on

 

[Davantrac]

I've got brass 4nine coming from 1 supplier and also this Astro https://www.fasttech.com/products/1467000 and I always keep a close eye on my batteries, inspect them before every charge for physical changes.

I'll put that on my phone as a spare cheers. Shame it won't go on ipad.

Loose the kick and build your Kayfun at 1.0 ohms.
I'd also loose the air flow screw.

I've built a ton of kayfuns and 1.0 ohms on an unregulated mech is pure heaven.

Drippers shine below .8 ohms.

Everyone always goes for a kick at first. I did too.
After a week mine hit the parts drawer and lives there.

Mechs shine without kicks.
If vv/VW is the goal, you'll be a lot happier with a regulated device

 

[Davantrac]

I am going to lose the kick, that is my goal. It will make buying cheaper in the long run. My theory is that mech mods have nothing inside to go wrong that can't be fixed.
Out of curiosity does a battery in mech mod last as long as it would in vv/vw when vaped the same? Basically I can get about 6-8 hours max out of my batteries on a vv/vw should I expect the same on a mech mod without kick?

Your vv/vw will shut off when your battery gets too low - around 3.3 volts.

Your mech will not shut off by itself;
so unless you keep checking or if the kick is there or you notice the drop in voltage from the vape itself, you could end up with a dead battery that can't be recharged.

 

[Davantrac]

Yes I understand about over discharging etc just wondering if the batteries last about the same time span.

Yes, it will discharge pretty much the same I guess; on a mech without a kick as the battery drops, the power you draw from the battery will also be dropping so I suppose in that sense it might last longer

When I got my chiyou and kick I used it alot, and it sure felt like the battery was lasting longer than I expected.

But that would be partly due to kick having a lower voltage cutoff than my vamo.

KICK + 4Nine = Bad MoJo
BE VERY CAREFUL!!!

You picked one of the touchiest, though excellent performing, Mods to get your feet wet with.
4Nine will only take a:
18350+kick in 18500 mode
18500+kick in 18650 mode
In both cases you still have to worry about Battery Fit.

Top is Hybrid=no adjustments
Switch is Floating Magnet/battery design=space limited

To much space=poor to no switch function
To little Space= Auto firing
