Mech mod + New Battery = Burnt Juice.

[CShaver]

Anyone else have this problem with Mechs? For roughly the first 30-60 minutes after putting in a freshly charged battery, I get super burnt hits unless I prime it enough to cause flooding.

For context, I'm using a Nemesis HCigar Clone, Kayfun Lite clone, and Sony VTC4 batteries. My juice is Hawk Sauce from Mt Baker.

The wick is getting enough juice, I've already made sure of that. I just can't seem to get a good tasting pull unless I either flood the coil or endure about an hour of nasty burnt taste.

What atty is this?...what is Ohm reading/resistance?...

Kayfun Lite clone, with a 0.6/0.7 coil.


After the "break-in" period with the battery, I get perfect hits for the rest of the battery charge.

"Break in" Period for the first 30-60 minutes,your battery is losing power, based on Ohm's law, you're pushing close to 30 watts on fresh charged battery..let's say it drops 4.0 volts..., around 26 watts..essentially.

Why don't you try higher resistance..from what I read..most people like their Kayfuns between 1.2 to 1.6 ohms...which is close to 11 watts with fully charged 4.2 volt battery...give it try, it won't hurt

 

[suspectK]

I use 0.7ohms in all my kayfuns..same build every time.. How is your airflow?

If it's Kayfun Lite , not the plus lite ....Certain Kayfun lite clones/authentic had air flow issues.......original poster can try drilling, but usually I don't suggest that and go with higher resistance...first...

Yeah I figured calling it a "break-in" period would sound better than saying voltage drop lol but I knew the concept

In all honesty, I've tried a 1.5, 1.2, 1.1, 1, 0.9 and 0.7 and the best vape I've gotten personally is where I am right now which it .6/.7 (two ohm readers, two different readings, so I must be right on the edge of the rounding lmao). Other than the burnt taste in the beginning. It's only happening on my VTC4s though which is why I was asking. My other batteries don't do it, but then again they're 10amp and not 30amp so that could be the reason, I assume.

My Airflow is as good ad stock ariflow could be I guess. I didn't want to fiddle with the Air Flow screw thing so I went with the Lite instead of the Lite Plus.

10 amp battery vs 30 amp...with you resistance...you're only pushing 7 amps...hmm...maybe it's not wicking fast enough for that much heat...too bad you can't see through the chamber...

 

[suspectK]

Ok.. I didn't read, derp

Raise your resistance..or find a drill press. You're getting less voltage drop from the vtc4's...so you can either stick a crappier battery in there for more voltage drop, resulting in less power, or you could *raise* your resistance, resulting in less power.

Also, if you feel comfortable with it..next time you change your wick, get some pliers to hold positive block, and loosen or tighten 510 pin to see what results in better airflow, but make sure where ever you want it at, the positive block stays secure. It could be a case of the airflow being hindered by position of airhole in 510 pin..

Its very possible. I've checked the chamber several times, and there's always plenty of juice on the wick and the juice channels are not blocked. Who knows lol maybe it's one of those weird things where I'll just have to deal with priming it and deal with the gurgle until the voltage drops a bit.

The 30 amp battery has a lower internal resistance than the 10 amp battery.
It probably has like 0.1 ohm while the 10 amp has like 0.3 ohm.
And more common batteries have more like 0.5 ohm.

Need to up your resistance if possible. One other option is to use the new Kick II chip. They can handle low resistance. When you go low res you have to have the feed sys to support it. May want to look at a dual wick say about 2 ohms per coil. One last thing if you put to much wick in the wells of a kayfun it actually feeds worse. I put in just enough to touch the bottom of the well plus say 1/8" more. One other trick if your kayfun will let you it to loosen the top cap a bit to force more juice in the wells. Some don't like this however and will flood. I have like 4 diff kayfuns. The best so far had two wells but 4 hole in the wells. On that one I can lay the wick on the bottom. FYI use Ekowool if at all possible.

Reason why you are having the problem on the Sony's is that they are a kic ash battery.

I've seen the resistance level differ by as much as .2V between standard battery and a low resistance like the Sony.

That difference is what's creating the problem.

The best two routes are listed below.

1. don't use the Sony anymore, use a regular battery.
My favorites are the Panasonic Hybrids.

2. Build your RBA to a Higher Ohm Level

What is happening is very common when you start going lower in resistance or when you get a new device that has less voltage drops. Your perfect set up, suddenly is going dry or flooding etc. I would try using less of what ever wick you are using. More efficient/ hotter heating, means your are burning thru the juice faster. Either use less wick material or change to cotton.

I had the same problem with my Kayfun. I was using Ekowool on a device and it was perfect at .8 ohms, but it on a much better mod and then suddenly too hot, burning taste. I just raised the resistance and started using cotton and it was perfect again.

 

[suspectK]

If it is wicking properly, you should see an air bubble come out of one, or both, of the juice wells after you take a pull or two.

I was actually looking at getting an Aqua just for the dual coil capabilities, but I haven't decided to pull the trigger yet.

As for the wick, I'm using cotton and I trim it enough to where it is just above the juice channel, barely barely touching ( but not blocking) it. Like I said, when I check the chamber, there's plenty of juice on the wick and coil.

Oh, they absolutely are. I love these batteries. The only other batteries I have are the Panasonic NCR18650PF, which are the Hybrids. They work well, but I've spoken to Baditude and he told me I could run .7 at the lowest with those and still be safe. Since I do .6/.7 I want to be safe and use the ones rated for much lower.

Like I've said, I've used .7-1.5 ohm coils and .7 gives me a way better vape than the higher resistance ones. I'm trying to have my cake and eat it too

I can't tell you how neurotic I have been checking this lol. Every single pull I check for the infamous bubbles

And yes, they're there as they should be

 

[CShaver]

So I figured it out...I'm an idiot.

My coil had a casing of burnt juice around it, and my cotton was bad. After cleaning the coil and dry burning the char off it, as well as replacing the cotton, I get no burnt taste from a fresh battery.

The things you overlook sometimes

 

[rucni]

some times the simplest thing is the last thing we check. i have been fighting with my kf3.1es clone all week on my hammer, the solution was to go back to my vamo.
