Warning!!! Compatibility Issue: Pioneer4you Seven30 mod and Kanger Aerotanks

[robtest]

For my second vaperversary, I decided to treat myself with a new setup... After looking around a bit, I decided to go whole hog and get one of the new Seven 30 mods and the KangerTech Giant Aerotanks...

So two weeks ago, it arrived in the mail and I was delighted. I got some of the normal coil replacements and a box of the new sub-ohm coils in .8 ohms to give it a try.

I enjoyed the new setup very much, and only had one complaint. Only thing I didn't like, and it seems to be the same in the Seven22, is that it can't step down the wattage and will just "dump" the voltage to the tank... Phil Pbusardo also mentions this in his review of the Seven22...
So for instance, I have it set to the minimum 7 watts and my battery is 4.09v, using an Aspire Nautilus with a 1.7 ohm coil, when I press the fire button the wattage display goes to 9.6watts... That in itself is not so much and issue, but I have the new Kanger Giant tank on it and been trying the .8 ohm (sub-ohm) coil ... On the minimum setting, on a fresh battery, it jumps to about 15-18 watts and gives you a fried taste if you hit it more than 3-4 seconds...

If you are using a coil that is 2.0ohms or higher, this isn't an issue, as 4.2volts on a freshly charged battery makes it very close to 7watts...

Then last saturday, I filled my tank as I had about 8-10 times before, and screwed it back onto the mod. Pressed the fire button and it seemed to work, but got no vape... Pressed it again, same same... Took the tank off, pulled it all apart, cleaned the coils, put it all together, put it back on again, still no vape. About the third button press, I saw a "Short" message on the screen...

Also, I noticed that the resistance on the display reads about twice what it should...

Pulled the tank off, and put it on one of my other vw mods, and it worked just fine... Tried another tank on the Seven30, and it appears to work, but get no vape... Pull that tank off, works fine on another vw mod... Tried a third tank, same same...

So, being I was 12 days of my 14 days of the EBAY return policy, I wrote my vendor and told them my story. They did write back and ask what tanks I had been using, so I told them and mentioned that I had also tried a freshly charged battery...

Then looking at their item sale page on EBAY, I noticed this in big red letters:

"** READ ** 07/10/2014 - There have been several reports, and we have confirmed, that there are issues when using Kanger Aerotank Mega or Giant with this mod. It either reports a "short" or "low resistance" on the LCD read out and does not fire. Please be informed of this before purchasing this item. ** "

So apparently, there is an issue with the 510 positive pin on the Seven30 MOD... I asked the vendor for a little clarification on the issue and what the normal warranty was on the device, so I could explain it better for you guys, who might follow in my footsteps... Here was the response:

"1) A one year warranty from the manufacturer, should be honored by authorized seller/dealer as we are.
2) After investigation on a couple of 7-30's we found the center pin (positive) to be off center. With the Aerotanks series the positive pin (7-30) tends to make contact with the outer post (threads/negative on Aerotank) even if the center pin is a little more than slightly off. If you can really tell that the pin is off center, it will create a short or read as low resistance. It can be corrected, as there is a little movement in the pin, by pushing/forcing the pin back to center. To do this you unscrew the little screw a hair, push it back to center and screw it back in. This issues is primarily dominant with the Aerotank series.

Now, the question as to what you want to do. We can open up a box, check the center pin and correct if needed. Package it up and send it your way with the return label for the other one. Or, if you wish to give up on the 7-30 simply start a return with eBay and a label will be generated for you (we pay for postage). Once we receive the mod in return we will issue a refund.

Please advise us of your option."

Looking at it, I couldn't tell that is was off center, not even with my reading glasses under bright light... But I do notice that the positive pin on the Naultilus is spring loaded and protrudes a little bit on a finer point, which the Aerotanks do not...

I really like the Seven30 mod, and the Giant Aerotank looks superb on top... I don't want to fry another one, but I did want another mod rather than a refund, so they are shipping me one... I guess I will use my Aspire Naultilus and my RBA tanks on it from here on out...

Have you tried adjusting the 510 pin up a tad? I've got a mega Aerotank with subohm coils and it works just fine for me at 12 watts.

 

[moecat]

I have a similar issue with the Cana clone using both the Kanger and Nautilus tanks. What I find to work is to unscrew the tank a touch until the mod properly fires.

The cana clone has a depression with the 510 connector for 22mm attys, the 30 watt Seven 30, the big aerotank sits flush with the 510

I tried messing with it a bit, but think it was already fried at that point... And being that they posted their comment 2 days before I contacted them, there have been others have a similar issue...

Actually, what I meant was that even with a 22 mm tank, the Cloupor won't allow me to screw in all the way. Otherwise, I get a "SHORTED" message. I have to unscrew the tank a little bit, and then I can fire away with no problem

 

[FatCat]

I had similar issues with a PT3, wouldn't fire on the seven30 but worked fine on my Vamo and MVP. Had no trouble at all with the nautilus or a cheap 5ml ARO. All my RBA's work perfectly. I believe the 510 connector design is just not that good, it worked OK for cartomizers but the larger size tanks and tolerances between manufacturers vary widely. The EGO connector appears to be better design offering more support for the tank, but the best vapes come from 510 hardware. What a revolitn' development!

I'm using the exact (EXACT) same setup you just described...... Seven30 with a Giant with 0.8 ohm head. When I first put it on, it was reading 0.00ohms.... I found I'd overtightened it a smidge and merely had to back it off a fraction of a turn and haven't had a problem since.

 

[ej1024]

Tank too tight,tank too loose, make sure pin is adjusted, never had this problem with both..

I have had my replacement about a week now... Still haven't braved the sub-ohm coils again on my Kanger Giant...

Found a thread over at "that other forum" with some burned out chips on the board...

The guy replaced it with an SX350 chipset and squeezed it back together Now has a Seven50 mod...

This limited edition seems to take care of the things I didn't like about the Seven30... slotted base, top cap and bottom cap...

 

[robtest]

So it seems like these guys have several kinda problems:

1.) shorting on kanger aerotank mega/giant seems to be both a slightly off-center pin in the Seven-30 plus the tight tolerance on the 510 pin of the tank in regards to positive and negative...

2.) frying the chip on the board... I am wondering if people are damaging them with a fresh battery and a sub-ohm coil at the lower limit...

A slightly overcharged battery at 4.2v and a .5 ohm coil would be ~35w, but you would think it would be build sturdier than that...

But just to be safe, I am only doing ~.7ohm coils in my Tobh atty...

why go subohm? Isnt that better suited to a non regulated mod?

why go subohm? Isnt that better suited to a non regulated mod?

while I really can't explain a reason for cloud chasing in itself as it is well beyond simply quitting smoking... Using a vv/vw mod with it's dc/dc converter gives a more consistent vape across the whole battery rather than just dumping the battery voltage to the tank/atty. A mechanical mod dumps 4.1v from the fresh battery but is only pushing 3.3v just before you swap it out...

now one of the issues I have found annoying with these yihi chips is that they do a wonderful job of stepping up the power but are lousy at stepping it down... so when I set my mod for 7 watts and put in a fresh battery on a 1.8ohm coil I actually get 8-10watts. I may have to upgrade to a mod with the yihi sx350 just because it steps down rather than because it does 100watts....

 

[Celtic Fog]

well there will be no doubt that the 100W should nail the sub ohm area....I saw that 100w box coming out, I am interested hehehehe. I love my VV toy, i was thinking of trying the 1.5ohm coils for my giant today, I have it on a Groove II.

Has anyone had this problem with the Sigelei 30 watt? It seems to have happened with me.

 

[Fearlessleader]

why go sub ohm? Isn't that better suited to a non-regulated mod?

Na that idea that mech mods are better for sub ohm is so wrong. I have a mech and regulated mods and my regulated are way better you need to move out of the stone age. Battery drop first can be compensated by just bumping your wattage up a tad also most juice has a whole flavor spectrum by raising or lowering the wattage a bit can totally change the flavor. Also early in the day maybe you don't want the vapor too warm but as the day goes on you want to turn it up a bit also feature like buck-boost are nice as well I can't find any drawback from using a regulated mod plus now we can even use TC and say goodbye to dry hits too the benefit mech mods have been that they are dirt cheap. I put mech mods in the same place as carto tanks.

Sorry but mechs have gone the way of the DODO !!

 

[Fearlessleader]

As A matter of fact, I ended up reading this post is I am doing research on seeing if anyone was able to put an SX350 chip in this mod I have a seven 22 that cooked on me the first day so they sent me a new mod for free so I gutted the 7 22 but it seems that I will go to a machine shop hopefully he will be able to make a bottom cap for the control where the positive contact comes thru and make the small section of the tube 3 mm longer, that how much longer It needs it to be to fit the SX350 in it. So right now I trying to see which mod will work the best for my purpose the Seven 22 or, the Seven 30 or the EHPro Mars 35 watt 26650 I know the seven 22 had the Sx 220 chip in it and this one has the SX300 and I can't verify the chip in the Mars I went there all the chips on the yYHHI

YOU SHOULD NEVER OVERCHARGE A BATTERY 4.2 is all she wrote now with a lipo you can get away with a little bit we did that racing RC cars but those lipo's take real abuse you charge then in 15min discharge in a 10 to 12 min race, let that one cool for 15 min while charging another
