Sigelei Zmax V3 and V5 Telescopic: User's Group

[JeremyR]

Oh if the circuit board Buzzes you'll. know it for. Sure. Mine only did It a few times. Hasn't done it recently. .. Actually started doing it this morning with 1.7 ohm coil. It seems like I can make it do it if I roll my thumb to the side of the button. I think it has something to do with the button on the board. Making poor contact inside or something. It normally doesn't make this noise, here it is with mic up to the body or screen.

As for amp limit 1.5 ohm @ 6 volts is 4 amps & 24 watts! 1.4 is re
Commended minimum

Your inconsistent performance it likely due to the button or pressure or angle of your push .

As for the black button it apears to me that is the only difference, the switch inside is the same from what I have seen .

My issues with it have been better today, it only shut down a few times like 5-10 times. I did contact 101 and they offered a store credit if I send it back.... I just really don't want to let it go! I still really like it, and they don't have in stock. Id have to order a chiyou clone before I sent it back so I got something good to vape on..

Yzer, mine operates down to 1.3 ohms.

@JeremyR,
You may have already come across this info, but if you haven't tried Noalox on your threads yet, I very strongly recommend that you do that as soon as possible, especially if you don't want to send back your PV. I could almost 100% guarantee that applying Noalox to your threads will take care of any black screen or cutoff issues you might be experiencing (as long as it's not an atomizer issue or tank connection problem). If you're already using it, then disregard the rest of this post. It gets brought up on occasion, but I just can't help but go on a rant about this once in a while because I get the feeling on occasion that people underestimate what a difference Noalox makes.

Noalox has proven to solve problems such as you describe for me and many other people that have posted in the sigelei forum (black screen and other intermittent problems). Run (don't walk) to Home Depot and buy a little tube of it for like 3 bucks if you haven't already. In my opinion, using it is not an option, it's a MUST if you want a reliably operating Sigelei. The Sigelei V3 should come with a tube of Noalox in the box if you ask me. I just can't stress this enough. If you aren't using Noalox, your asking for headaches and head-scratching as you stare down at your Sigelei wondering what the heck is going on. I've been there and done that.

The electrical connection in the threads is VITAL to ensuring that there is a good "ground" connection back to the battery. The threads on the Sigelei are pretty loose, and if your thread electrical connection is anything but rock solid, your Sigelei will not perform well consistently. Period. This has been verified through first-hand experience from many Sigelei owners participating in this forum.

Don't do as others have and succumb to the temptation to use e-juice because it's "easy" and keeps you from running out to the store for Noalox. The difference between e-juice and Noalox is like night and day. All experienced Sigelei V3 owners would recommend staying away from e-juice. E-juice will lubricate the threads but isn't very conductive to the flow of electricity whereas Noalox is "highly" conductive and makes all the difference.

If a V3 owner isn't using Noalox, I would go so far as to tell them not to even bother posting in the forum about performance problems because the first thing we're going to tell them is to apply Noalox. Once that's out of the way, then we can be pretty sure that poor thread conductivity is not the problem and we can get down to helping them with what the real issue might be.

Those of us that are using Noalox have seen the difference first hand. In my opinion, it's the #1 thing a Sigelei V3 owner should be doing on a regular basis to avoid intermittent problems and improve consistent performance. It's like changing the oil in your car. It has to be done regularly and changed out when it gets old. I replace my Noalox every 2 or 3 weeks when it gets too contaminated with dust and grime (or as soon as I start to notice problems again). I clean my threads with alcohol, an old toothbrush (reaches down into the tube nicely), and a rag or tissue before applying new Noalox.

I couldn't get this to play on either of my machines.

Yeah yzer I'd have to upload it to youtube later...

Ok yzer and fairmana ..... You have talked me into it I will have to run out and get noalox!!!

Your right the threads are pretty loose and I see grit gets into it possibly enough to raise the res of the ground contact and noalox will act as a sealer while maintaining a good ground. With the 8 threads there I would think one would have good contact but we are running a lower voltage then a 12v battery and it's probably more sensitive on the ground. If it works I can deal with occasional button issues. Sounds like its well proven In This application

Thanks!

Glad you are going to use Noalox. I suspect everyone should be using Noalox with any telescoping mod that has a threaded tube design. There should be some slop in these threads if you push up on the bottom of the APV with a battery installed. This slop isn't enough to make the telescopic tube wobble during use. People over tighten the tube or push too hard on the fire button and find that the Sigelei works better for a short while. Then, they discover that the screen or button have been displaced and have ruined a good rig.

It just makes sense to use Noalox and have good ground continuity along the tube without over tightening the tube and trashing the electronics.

Both Chinese and US APV makers fall way below the mark when it comes to providing useful instruction manuals with their gear. This has a lot to do with expenses involved in printing anything nowadays. The Sigelei Zmax Telescopics are not always the best choice for people completely new to APVs. These sophisticated devices require regular care and careful operation for a long life, just like firearms for instance.

I picked up some noalox yesterday, because the bottom firing button on my nemesis was getting very hot. A sure sign of bad conductivity.

Did the trick. I'm a believer in noalox. Wonderful stuff.

Curt.

Great decision! I promise you'll be happy you did!

 

[RatInDaHat]

if you can't find noalox, oxgard seems to work well for me.

 

[Thayamax]

I got some Noalox about a month ago after having my Zmax since last March. There is a noticeable improvement.

Here's a link to the noise comming from inside occasionally. The mic is up to the screen. Towards the end I move the mic up to the atty and back to the screen and you can hear how the coil just sizzling like normal.

I'll describe the sizzle of my LR cartos as a white noise with occasional pops and crackles. The "rattlesnake" I hear is like a sound dropoff several times per second in that white noise. I only hear noise coming from LR cartos, not the Sigelei. The sound that comes from your Sigelei is a higher pitched tone. I've never heard that from the Sigelei or the cartos.

Yep, same sound I hear.

Yeah, I can easily distinguish between the coil sizzle and the PWM rattle. That PWM rattle is very distinct, and I'm pretty sure I've never heard it quite like that before.

At any rate, don't assume anything is wrong just yet. Wait till you get some Noalox on your threads and try a different atomizer/carto setup just to see if it continues.

 

[JeremyR]

Yeah I totally agree this could be due to low power from a bad ground causing the pw modulator to over work to boost the voltage.

On another note I have been noticing the body gets warm I thought it was just picking up body heat from holding it but I was testing it by only holding with two fingers at the button and it did get hot at the threads one spot was the hottest .. There is definately high resistance at the threads.

I have been thinking if there was a way to test the resistance of the ground. One lead at the ego threads and another at the vent hole on bottom. I need a battery for my multi meter... Anyone care to try it? We could get a baseline if it works.

My wifes started burning everything like the voltage regulator stopped working.

You could go up to 3-4 ohm coils and still use it at 6 volts. I regularly use 3 ohm coils and they perform very well at 5-6 volts. 3.5- 3.8 would probably be good at a solid 6 volts.

 

[JeremyR]

I've been thinking about this for weeks don't know why I haven't tried it yet.... Wrapping foil around the threads. Like a conductive thread tape. Aluminum foil is more conductive than stainless. So far seems it's working good, tube is much tighter.. Will see if my problems persist today.

 

[yzer]

Consider that JeremyR's Sigelei is a defective unit. He reported a displaced button on Dec.8, so his unit does not represent a Sigelei that is functioning properly. He also reported on Dec. 8 that his unit had not been working right for three weeks.

JeremyR, I hope you can get the Sigelei fixed. Given the problems you have had with it I wouldn't expect too much.
