Hecknaw, I'm the other guy with the 401 Chuck... it is great especially with the EVO Carts... they hold more liquid and have a greater surface area for better wicking than standard 401 carts...

Either way, the Chuck and 401's Rock, you will be pleased...
i really needed to here this!! and thank you for your words.i thought that the cart issue would be the down side of 401 w/this mod or any mod. if ya can, please get back to me about where i can pickup these evo carts. or send me a pm

I posted this over on the battery thread, but I think it really belongs here on the Tech thread.....

I have a 3000mAh 18650 here that reads 4.2V on my fluke meter, but does not produce vapor. I assume it is a bad protection circuit not allowing the 1.7A required by my 510 atty to get through.

Has anyone else seen this on any batts?? (18650 or otherwise)
Anyone know of a fix??

tried another battery and it worked with that?
SO, you can try leaving the battery in the charger for a few days BUT the only thing that has worked for me sometimes is put the battery on a POWER Supply and crank it up to about 12 volts slowly, don't stand over it and stop when it gets a little warm. Check and retry as necessary.
BUT all the batteries I've had that failed on protection didn't read right on the meter

ALSO have you checked at where the att screws in for voltage?
I know there are many failure modes for the protection circuits but if it's got voltage it vaps IMHO
Some of these batteries have recessed ends, alwase made contact in my chuck, but have to fiddle with others
what fluke you got? not that it matters

As long as we're on chuck tech... why dont we make a 510 adapter to a flashlight or strobe or something... a tazer would be cool... "the rabid badger vaping tazer attachment"... got a ring to it....
Oh, you havn't been to the 5 volt thread to see FrakenChuck yet?
I was going to put a PWM circuit, run it at 6 volts and put an adj screw to set the volts to the att
i thought i was staying on with highping, just help troubleshooting his chuck (or blowing his battery up). becouse of YOU i put the photo of FrankenChuck up and NOW i'm thinking how a tazer would work......with the PWM i could ..... might be self cleaning..........Oh ya THE HIT.

It's definitely not anything to do with the connection, I get 4.2V with it in the chuck and measuring at the connector. It measures 4.2V until it gets a load on it. I need to hook it to a pot with my meter in line. Then crank up the load til it cuts out. My guess is it is just cutting out somewhere below the 1.7A my atty is drawing.

OK, it's a protection circuit failure, be careful trying to use a pot, make sure it's a wire not carbon pot becouse you are going to be at the very end to get 1-10 ohms.
I'de try abusing the battery, nothing to loose, try shorting in with a wire to discharge it, if it is putting out amps it should burn your fingers and you'll see the sparks. could alwase put an amp meter in the wire and see how much it's putting accross a short if any, the idea is to get it ready to take another charge again and see it that resets the protecction circuit.
or not

Ok I've tried draining this batt, with no luck. Put a wire on it for a dead short. Zero spark when I connected the wire. Left on for an hour, still reads 4.2V. It's got to be a bad PCB.
My next attempt to beat this thing into submission is going to be to put a 10K resistor on it and leave it overnight. If that doesn't drain it, it's going in the trash.

I don't know why I'm even putting this much effort into a 7dollar battery. At this point, I think it's more about winning the fight than anything.:rolleyes:

I popped 3 510 atty's on a chuck with 6v(2 tenergy rechargeables, so maxxes at 7.2 v when fully charged and new).

I had an adapter from Janty for an 801, and wasn't happy with it because it has a 0.22 ohm resistor on it... so, I thought what the heck, mights well take one more chance...

510 chuck, altsmoke adaptor 510 to 801, Janty's adaptor for the stick at 0.22 Ohms resistance, and a 510 atty. Vaped all night.

Still, I'm finding that the tenergy's are just a bit much for the 510 at 6v- but dad gum it, I pulled apart a Janty adaptor that they "recalled" (stopped producing and changed the resistance) that was 0.68 ohms I think. I betcha that would have worked pretty good. Everyone hated them on the stick.

If I pull apart the adaptor I have, and install another resistor, does anyone have suggestions for what value ohm resistor to try for a hot vape on a 510 that won't blow the atty? The 0.22 didn't seem to be quite enough. I thought the puresmoker used a 2.0 ohm resistor in their product to get a 5 volt vape, which I'm guessing would be real nice on the chuck, but I'm kind of unsure. Any comments would be welcome!

Then again, most say that the big chuck with a 18650 vapes like a 5 volt, so maybe I'm wasting my time. The BC is the best 510 vape I've ever had at 3.7, so I'm in uncharted waters- the 0.22 did melt the cart body a bit, and it got pretty "burn" tasting pretty quick.

um... EXCELSIOR! *Quack*

With a 10k resistor it is going to take a lot more than overnight to drain it if it has any charge at all. A 3.7v batt running through a 10k resistor uses .00037 amps or .37 ma. Every hour's use would be .37mah. A fully charged 3000 mah battery would last 337 DAYS at that rate! 8-o

I think I'm a rather patient person, but I don't think I could wait that long. I'd try something around 10-50 ohm so it'd take around a day, just watch the wattage on your resistor so it doesn't burn out and stop discharging while you're away from it.

yeah, 10K will take forever, I was just throwing out a high number. I think the only way I'm going to find out what current the PCB is cutting out at is to put a pot on it and put my meter in line. Then start with a setting on the pot that gives a small mA draw and slowly turn the resistance down until the amps cut out. Then I will know exactly what the cutout level is. Not that it will do me any good, just curious at this point.

Just wanted to post this here...

E-cig Multi Adapters - Wholesale & Retail Best E-smoking Supplier

Much better deal on the adapters than Altsmoke.
5 adapters for $8 instead of 9.95 each.
Also, if you are making an order for adapters from here, you can pick up some great deals on other hardware (Attys, carts, etc.) at the same time.

I already posted this over in another thread, but I want to try to keep this Tech thread complete and up to date with this kind of stuff...

Walgreens carries a diabetic case that works really well for toting the chuck and accessories. The Chuck fits in the spline. It's made by Case Logic and it's around 15 bucks. Lots of soom for attys, juices, batts, etc...

Wow, I know I read from someone to clean the battery connections and your atty threads with Electronic Cleaner. Well I found mine, did it, and Holy Cow!!!! My atty's are about two months old...had 10, they are 510's. One popped the other day.

So...if you don't have any Electrical Cleaner get some. Spray it on a Qtip and try it. 8-o
