YES! SIgelei 75Watt TC arrived, so far, very impressed.

[conanthewarrior]

Hi people. After realising the majority of my vaping is done between 50-70 Watts on an RDA, and 20-40 watts on a RTA, I realised my 150 is a bit cumbersome, although I do love it for the length of time between charges.

So far, I am testing my el cabron between 50-60 watts with a samsung 25R. I have an LG HG2 for it, but that is charging.

I can not yet try temp control, although I have ordered some nichrome, but now understand NI200 would of been better, so on Saturday I will order some of that as well. I will try the nichrome though, see if it does work.

I understand the battery life will be a lot shorter as it is single 18650, but I will be using this as my daily take out vape due to its size, is it virtually the size of the Mini, just a bit wider and about 5MM more depth!

I did see someone got rid of his on the first day, due to high power vaping only lasting 4-5 hours. For me, that is perfect. I only go round my friends houses for a few hours at a time, and if I was going on a longer trip, I would take the 150 due to the 2 day + battery life on 25R's.

I can not comment on the TC, but as soon as I receive the correct wire, I will update. It may allow my fiancee to try a higher wattage, as she says 60 watts + "is too hot and feels like it burns" where as to me it feels like a fairly warm vape. She is used to the 30W Mini though, and can't go above 20 or it makes her choke.

So I've made her some slightly higher resistance coils that work fine around 12-14 watts (she made them, following my directions as I made the other one for her)

Hopefully this will allow a 60 watt vape to feel cool, and thus not make her choke.

I have had the device for about 30 minutes, but so far am amazed. I will see how long I get out of a 25R with my normal routine, using an RDA and when I go out I slap my lemo on and drop the wattage. Even if it is 4-5 hours, I will still be impressed due to the size and it being single 18650.

Also, the rattling issue has been fixed in this batch.

One last thing that made me happy, it come with the sigelei protective condom! (I call its sleeve its condom, as it protects it from nasties). I got a opaque one, which looks OK on the silver and black, I don't think the opaque one looks right on my 150 though so I am ordering a blue, green or black from fasttech to replace it with a solid colour. I always use the sleeves, as I don't want scratches, and if I do drop it it offers a little protection.

So, so far, the Sigelei 75 gets a 10 out of 10 for me. I will update this thread over the coming weeks with any noticeable problems, if there even is any. But at the moment, I give it a 10. (I know its a new item, and thats probably why I like it so much, but It will reflect in the next few weeks after the new device effect has worn off, and if I still rate it at that level.

I will try to be as unbiased as possible, with any flaws or defects I will Update in this thread.

Anyways, I got to go as I have a new toy to play with, just waiting on a mutation mini and a ultra mini 1ML RDA (14MM diameter, its tiny, under $3 from fasttech, its been two weeks but can take up to 3 my postman said, and I went for the cheap, free postage so expect the full 30 days, which is just over 4 weeks).

Happy vaping people!

Well, One thing I have noticed is it does not increase voltage much, meaning the 25R's if used at the full 75 watts, will be over drawn if not fully charged. With a fully charged LG HG2 in it, at 75 watts, the device is using 4.6 volts. Step this down to 60, it is 4.1 Volts.

At 50 watts, it is 3.8 volts, at 40 it is 3.4, at 30 it is 3, at 20 it is 2.4 volts, and at 10 watts it is 1.8 volts.

I expected a slightly higher voltage than this, allowing more headroom/safety. It means that even at 60 watts, with a LG HG2 I only have 22% headroom. I am going to keep my eye on the voltage as the battery drains, as it could lead to an unsafe amp draw.

I did get a high temp warning earlier, the battery was quite hot. I think I will be using this for my tanks and keeping the 150 for 60 watts, as there isn't enough headroom there for me to feel safe.

This reduces it from a perfect ten to about a 7 or 8, as I can not use my RDA's or its full wattage with a good amount of headroom, I am probably sticking to my tanks between 20-40 watts, as in that area, it seems safe even if the voltage is 3 volts.

This is unless I don't understand the way the mod is working, which I could be. I am using it in power mode, not temp control mode.

EDIT: What a complete pleb. I was using a 25R that was not full, the LG HG2 was in my charger. It seems the lower the coil is, the lower the voltage? I really do not understand this, but with a 0.53 coil it is well above safe limits In a good way, lots of headroom.

 

[conanthewarrior]

Right, I am confused. I am now using a 0.53 Ohm Tank, and the voltage DOES go to a very safe level. Before I was using a 0.29 Ohm dual coil set up.

Now, at 50 watts it puts out 5.11 volts, at 60 it outputs 5.63 volts, at 75 it puts out 6.30 Volts.

This is much safer than before.

Although, I am now left scratching my head, I didn't think the resistance of a coil would change the voltage it put out? This puts it back up to a 10 for me, if the problem is solved?

EDIT: I change to a dual 0.5 ohm setup, and now the voltage steps up as I expected it too. It is rated to go down to 0.05Ohms, but under 0.5 Ohms the battery seems to do some funky things.

Seeing as I can't really go below 0.5 safely, the device goes down to a 7 and a half stars. Still a device I would buy, I just wish I knew it did this BEFORE I bought it.

 

[conanthewarrior]

Ok, 0.4 results in a safe battery level too, it seems under 0.4 gives you the actual voltage of the battery, not stepped up to a safe usage level. So, anyone else with a Sig75 notice this? A bit annoying, as it says it supports up to 0.05 Ohms, maybe it was them two particular coils it was giving strange voltage with? I tried them again, same thing with the voltage, then made a dual coil 0.44 Ohm setup for my el cabron, and the voltage is at a safe level.

I will try 0.2 when I get home from the gym, and see if that works, it may of just been them coils, or even 0.3something Ohms triggers a flaw, but I will find out if that is true later when I try. For now, I know 0.4 and above is safe.

 

[conanthewarrior]

Right, it is anything under 0.3. If the set up is under 0.3, the battery does not step up the voltage like it normally does. Over 0.3, it steps it up as it should.
This is quite a big issue, as it states it fires down to 0.05, but if the battery is outputting 3.8 volts at 75 watts, this is not good, it will over draw the batteries, by 12 percent according to vape calculator.

Who else owns a 75, and can they confirm if they also have this issue? Apart from this, I love the mod. Luckily I dont mind coils over 0.3, so Its staying, but if you want to build lower, I can not recommend it.

 

[conanthewarrior]

Well, I have a 0.26 Ohm build, it started off the same. It is now slowly changing. The more I adjust, the closer the voltage gets to what it should be. It is like it is 'learning'. It is not a Yihi in it, I did not recognise the chip but it does seem to be an in house chip.

Like at 75Watts it is now 4.8 volts. This leaves me safe with a 25R, although it should be rising up to a maximum of 8.5 volts, it only does this on 0.3 and above coils.

 

[conanthewarrior]

Well, I feel a bit sheepish now. I had it in power mode. but never owning a TC mod before, I didn't know about the 'set resistance' sequence. I have done that, and it seems the voltages are more what they should be for that wattage. Still a little on the low side, as in making the battery put out 10-15 amps, but It could of been user error. Since I have set resistance, it is operating higher voltage wise.

I am a real donut.

 

[conanthewarrior]

Anyone got any ideas why at full power it only runs 4.8 Volts? My 150 at 75 runs about 6.3 volts. The manual for the 75 says it runs up to 8.5 volts though, so can't be that. I am using it on POWER mode, not TEMP control mode, and above 0.3 I had it hit 6.3 volts at 75 watts. That was with a 0.4 Ohm dual setup.

 

[conanthewarrior]

I would like to know if my unit is faulty, or they all do this below 0.3 Ohms? As if it is faulty I will get it replaced from my shop, if normal, then I will be OK. I just find it odd that The maximum it draws out under 0.3 ohms at 75 watts is 13 Amps, below that 0.3 14-15 amps is normal across the whole wattage range.

 

[conanthewarrior]

Now is coming towards the end of the first day. Even with the voltage not being as high when using lower resistance, it is still within a safe level for the battery,with around 5 AMP headroom, so, for me, this gets a 10 as a regular mod box. I will update finally when I have some Ni200 to try properly. If anyone has the answer to the voltage difference below 0.3 though that would be great.

 

[st0nedpenguin]

I have no idea what you're referring to when you say "safe voltage".

 

[conanthewarrior]

Right, now is time for bed. I must say, apart from the voltage worry (when I entered it into the calculator, all was fine, even when the battery was low at just under 0.3, highest load was 16 amps, lowest was 14 amps) but when I use my lemo with a .5 coil, the voltage increases like normal, and places less stress on the battery.

I have emailed Sigelei to see if this is normal, or a defect, as I am thinking it may be a way they get longer battery life with a lower resistance coil? As long as you are using a 20 AMP battery, you are fine. I made mis calculations earlier, and it seems to be keeping about 15 Amps across the wattage by dropping or increasing voltage if your build is below 0.3. Over 0.3, it works great and at 75W is 6.3 Volts, and much less strain on the batteries, but both below and above 0.3 is safe, with a samsung 25R, the LG HG2 didn't seem to last much longer than a 25R. But then again, I was using it much more powerfully. Lasted about 6 hours of constant use, as today I was constantly using the device to get used to it.

I can not wait for my Ni200 to arrive, then I can review the temp control. As a plain 75 Watt mod box, it does what I want, it will mainly be used for chucking a tank on and going out due to being the same size as the 30 watt mini, occasionally an RDA if I go to a friends, but the 150 is more for my RDA's and home use, longer battery life and that.

Overall, a well made mod, just confused on the voltage issue. I would buy it again if I lost it as nearly all my vaping is done under 60 watts, unless using claptons I use around 80+.

If anyone knows the answer to the voltage thing under 0.3 ohms, please tell me as I am baffled. Is it faulty? Even if it is, its within safe limits for my batteries, although I think it is meant to happen to help save battery or something.

 

[conanthewarrior]

I have no idea what you're referring to when you say "safe voltage".

If I build a coil under 0.3 Ohms, and raise the watts, the battery voltage on the mod doesn't raise as much as it would with a coil over 0.3 Ohms, thus putting more strain on the battery in the amp area.

75 watts is 4.6 volts with a 0.2 vs 6.3 for a 0.4.

EDIT: Changed some words around as i got confused, as is part of my problem. (Me, not the mod).

 

[st0nedpenguin]

It doesn't increase as much because it requires lower voltage to hit the required wattage with a lower resistance coil as per Ohms law.

Well, slap me and call me Charlie lol. I forget things easily, as I am brain damaged, I wasn't sure if it was a fault or not. Now I know its not a fault, I am even happier.

 

[conanthewarrior]

This has really made my day better, knowing the unit is not faulty. I had some bad news with the doctor earlier, so recieving a unit that isn't faulty and works fine makes me feel a little better . They want me to go onto alendronic acid due to my osteoporosis, but I dont like the side effects of 'jaw necrosis' and 'spontaneous fracture of the femur'. I don't want to end up with jaw necrosis and lose my lower jaw and be known as the guy with half a face. If it would happen to anyone, it would be me I can almost gaurantee it.

I just checked my 150, it does the same. I just never noticed before. What a donut lol.

No.... That would be Watt's law. Ohm's law has nothing nothing to do with wattage.

Is it just me, or have variable wattage devices created a huge population of vapers that really have no idea what they are talking about.

As wattage is the result of applying a voltage to the load, you really should not be setting it. Your mod supplies voltage! That would be like your employer telling you your scheduled for $1232.55 this week.

Sorry... just the electronic theory and law Gestapo doing a drive by.

Ok, so just so I get this straight, a lower resistance coil requires less volts to get the same watts? And Ohms law is not involved? I ask as pretty much a newbie, who has been here a few months.

 

[cascadian]

Yes... Ohm's law established the relationship between Voltage, Amperage, and Resistance. Watt's law established their relationship to power, measured in Watts.

Just a bunch of vapers who tend to use Ohm's law calculators of which most include resulting wattage.

Arguing semantics doesn't change the fact that the results are the same.

But my bad, clearly referring to Ohms law instead of Watts law means nobody has any clue what they're talking about.

 

[conanthewarrior]

Thanks you both st0ned penguin and Jim_MDP for explaining to me.

I can not believe I did not notice my other devices do exactly the same under 0.3, well my 150 does anyway as I can't go under that on the 30, and the missus has that now.

The 75 is a perfect replacement to the 30, and for me, it gets a 10. I have tried various builds, I tried nichrome this morning for temperature control ( I now know that is not as good as Ni200, but I have ordered 37.5 Meters of 26 gauge, 15 meters of 30 gauge Ni200 for now), and the temp control did seem to work. I used the cotton burn test, that seemed to work, and the temperature could be adjusted from cool to warm at the same wattage. I thought that was amazing, the missus had a go at 60 watts for her first time and didn't choke!

I will get other gauges as I need them, but I thought 26 and 30 should do me for now.

 

[conanthewarrior]

I was fogging my room up having fun, and the RDA was getting very, very hot. I did get a few high temperature warnings, but leaving it to cool for a little bit and it works fine again. I checked its not the battery, it was warm, but the RDA was scorching so must of been making the rest of the device hot. That was with an El cabron at 60 watts, I was really hitting it hard to fill my room for fun, a lot more pulls than usual, I would say around 4 times the amount of my usual vaping, it was just vape, breathe out, breathe in, vape and so on.

But, it kept me safe with the High temperature warning, so thats another star for it for me. Still a 10.

Thanks man, they have some cool stuff but I am in the UK, wonder if they ship? I will check on there or ask. I won't be able to buy anything for 2 weeks anyway, as I used up the last of my money I put aside to spend on a Velocity RDA

(Tobecco clone, I could not afford or want to pay the cost of the original. Tobecco's clones have always been great quality, even my friend who.s father works with metals and machining said I wouldn't even call that a clone , look at the threads and workmanship in it. He thinks It come out the backdoor instead of the front, similar to what was going on with epiphone a few years ago, the Chinese would make say 1200, 1000 would go out the front, 200 would be sold out the backdoor for a real amount of money. They just lacked the logo, but serial numbers and such were in place. These are now sought after. I don't believe it to be a backdoor job though, just a very good clone, well my el cabron is anyway, it come with all the spares EXCEPT the centre post, and all 3 drip tips of the original, and the Mutation X V4 I got my fiancee is also high quality, so for £13 and thats in the UK so I don't have to wait a month, it will be here Tuesday and I can not wait to try it.)

Also, if anyone could send me a link or something actually explaining how regulation works, that would be great, as when I was building below 0.3 I thought it was taking the power straight from the battery due to the voltage. I know that is a facepalm, But I wan't to know how regulation works exactly, it doesn't matter if its slightly technical as I repair PC's and phones, doing my COMP TIA A+ course with Cisco soon, I can not wait.

12 month home course, and I am then qualified to be a support engineer, desktop support engineer, or work from home, whatever I choose. I will probably work from home at first due to my conditions, I don't think the stress of an office will be good for me.

EDIT: I forgot to say, the el cabron has a sort of cooling fin base, It does help but it still does get scorching when run High. If I go single coil and say 30 watt max, it just gets warm. I know in theory it is just 2 30 watt coils, but they seem to really ramp up the heat quick.
