DNA 30 Clone constantly reading "Too Hot"

[Sean Di Rienzo]

I purchased this DNA 30 clone from Focal-Ecig. I am aware that the chip is probably not a dna 30 chip but some knockoff.

For the first month of use I had no issues whatsoever. Recently however though, it will randomly read "too hot" and stop firing. It won't shut down or anything, there is no venting or excess heat coming from the battery or board.

The "too hot" goes away after 2 seconds and It can be used again. It will happen on a freshly charged battery on the first fire, or halfway through a 10s inhale.

All that I can tell you guys is that I feel no excess heat coming from the board or battery. I am using an efest imr 20a 3100mah.

It reads "too hot" even on 2 ohm coils in a clearomizer. I usuallly run .6 ohm on my rda and the results are the same.


Any ideas?

i've read this alot about these regulated devices. I'm glad I never pulled the trigger on any of them.

You're using a 6 amp continuous battery. Efest lies. The connector on that box is junk. Have you destroyed the insulator?

 

[Sean Di Rienzo]

I am aware of the controversy regarding efest's rebranding of inferior batteries. However, the 3x 3100mah efest's that I own claim to be 20a and have worked beautifully on my mechanical mod thus far.

The lowest I will ever run is 0.5 ohms, which still scares me if what you say is true ( 6 amp).


I feel that this is definitely the box mod's issue and not the batteries.

 

[BoomStick]

I mean efest lies about battery specs. They rewrap other manufacturer's batteries and change the ratings. You can look in the connector and should be able to tell if the insulator that isolates the positive pin looks split or has chunks missing. I would just do a real good visual inspection of every solder joint, connection, everything. Also, you need a different battery. You need at least a 12a battery which they don't make so that means you need a 20a battery. Yours is only 6amps regardless of what efest says.

Absolutely correct, I have repaired quite a few of these and they have cold solder joints.

 

[Sean Di Rienzo]

I have no experience with soldering whatsoever so I doubt I'll be able to repair my box mod.

In terms of batteries, I feel absolutely duped. I own 3 of the efest 3100mah "20a"..

The main reason I purchased them is that access to sony vtc's is scarce in Canada.

Does anyone have any recommendations for some good 20a batteries - I will do some homework to find Canadian retailers?

And does anyone know of any individual offering repair services on box mods? I really love the APV/APW aspect and the look of the box mod. I would absolutely hate for it to be unusable.

There is no such battery as a 20amp 3100mah Efest have you tried some IMR or INR batteries in i Two things could be happening the first is the most likely but could have started a problem that may have created the second problem.. Firstly running a 6amp battery at .5 amps is going to heat that battery up and everything around it tripping the heat sensor on the board.. These cheap DNA clones use HOT glue to hold everything together it is a horrid proactice now with you using that battery you could have heated the glue up enough to cover more of the chips on the board which is creating no heat dissipation.The first thing to do is use a quality battery no BS battery if it stops fine if not.. then well its probably a ticking time bomb.. but I bet as soon as you change the batteries the prob goes away

FWIW, I just got one of those from Focal. This one specifically: http://focalecig.com/Product/-Ship-from-USA-HANAA-MODZDNA30-ModSilver-18650--14074

Yes, the battery holder's solder joints look a bit cold to me. But, the connection seem physically solid, so for now I'll overlook it as I'm not a big sub-ohmer. I did try it at 0.9 ohms dual-coil and 30W just for fun, no issues except it was too warm for my taste. .

I'm using a Samsung 18650 25R 2500mAh battery in it however.

It's a legit 20A continuous cell and I bought two for $17 from here on Ebay:

http://stores.ebay.com/GenuineCells...b=5652316011http://www.genuinecells.com/shop/

They also have others like the well-documented 20R with higher rating and less mAh.

Save the Efests for regulated mods or > 1.0 ohm IMHO.

The Samsung 25'rs are good batteries and for 42.00 and some change ya cant beat getting a Hana I still wish my Hana clone did not start on fire.. I liked that thing

Bummers...

Yeah, I've seen enough internals horror pictorials on FT forums to know it's a cheaply made mod.
But, I also couldn't even begin to build one from parts for $45 shipped. But, I can mod this mod if needed.

I do baby my mods, and don't do this 'extreme' vaping thing very much. First thing I did was to slap a 510-510 adapter on there to ensure I don't fuck up the connector. Screw the looks, it ain't leaving the house anyways.

Yeah easy fixes if it messes up I'm taking on a DNA 30 evolved tube mod soon to put DNA 40 In For giggles

 

[Sean Di Rienzo]

How can I tell which batteries and authentic and which are rip-off's?

My only resource for purchasing quality batteries seems to ebay, or us retailers with extortion shipping rates.

If I were to purchase a samsung 20a or sony 20+ a how would I know that it's real and not just another re-wrapped battery?

Should I be scared to use the 3 efests I have now? I've been using with my mech mod for weeks with no problems.

Samsung or Sony vtcs are reliable yes? But IMR's are safer than li-ion ?

 

[MKPM]

Odd! I vape my God Box anywhere from 120w to 180w with a .59ohm dual micro build and have yet to see it go over 30c at the chip. I run three VTC4's in it.

The songs so far appear to be the most forged etc. Do a search on Google there are some great examples of fake Sony you should be fine with the Efest unless you forgot to tell us you Cat ran off with part of your face blown off

 

[Sean Di Rienzo]

I will purchase one of the higher quality batteries to test. If the "too-hot" persists, I can assume it's a problem with the focal-ecig dna30 clone.

I also want to mention, I vape it with the cover off, and when the too hot sign appears I am using my hand to sense heat in and around the battery and motherboard area. There is nothing excessive whatsoever. This did not happen for the first month of ownership so I agree with whomever stated that the glue might have melted and shorted something.

I am seriously contemplating purchasing an authentic box mod product. What are your thoughts friends?

I want to say that I really appreciate everyone's support. This community is amazing and you are all so helpful.

 

[LoveVanilla]

I've seen this from time to time. Seems to occur more when using short on/off cycles and less frequently with longer power cycle/vapes. This is just an informal observation. And I'm not a sparky so no explanation from me. Try modifying your vape style to longer draws and see if that makes a difference.

I fear the that you may either have a bad board they throw hot glue all over these CHDNA boards and its causing a overheating situation or a wiring problem ... good luck good thing is Mods are cheaper than ever and picking something up of higher quality wont kill the pocketbook

 

[Sean Di Rienzo]

Yes I completely agree MrScary. I looked inside the box a few moments ago and there are indeed globs of glue covering what looks to be a capacitor or two

By cold-soldering you mean poorly soldered with a "cold" soldering iron : therefore poorly soldered?

Like I asked before, is it even worth attempting to repair or should I just get an authentic

@LoveVanilla

I have tried that. The "Too Hot" appears even I'f i'm running a 2.2 ohm coil on my kangertech protank (at 8w) Which is less than 2 Amps

I cannot really answer than Sean it seems you have the skill to open it if you feel confident remove that hot glue from the chips and capacitors that may very well solve your issue.. When I said Solder check the wire connections and make sure there are no frayed wires etc that is what appears to have made mine go up in smoke... ...Personally I myself take them all apart and check them I would remove the glue check for frayed wires and loose solder joints and giver her a go.. if she does not start the over heat issue prob solved with a Caveat I would suggest getting better batteries for low ohm usage .. Godspeed

These connections appear to be tarnished and not shiny, use a low watt iron to fix them up.

 

[Sean Di Rienzo]

Thanks everyone for your help!

I have one more question. I am scouring the interwebs for batteries. The problem is, the box mod only works with flat-tops, and my mech mod seems to work best with nipple tops. I can still use nipple tops in the mech mod but I must unscrew the contact down several mm.

Are nipple tops avoided? or is a Samsung/Sony 20+a nipple the same as flat?

Thanks!

Which mech are you using most have an adjustable flat to pin

 

[BoomStick]

Orbtronic is a good source for batteries. Not sure about shipping rates to Canada.

Some efest info.

im using a focal dna30 right now as well while i wait for the vaporshark and the chip is most definitely retarded. when i fire it up to the 10 second cutoff it uses the "too hot" message to let me know ive fired it too long, nothing to do with the internal temperature. and im not completely sure it regulates the entire battery, i was vaping a 0.7ohm and i noticed the vape was getting weak as the battery died. so i turned it up to 30w and nothing changed, it was like using a mech with a completely dead battery. the dna i had before this was a cloupor, it shorted once and fried the chip (it could have been my fault but evolvs chip wouldnt have done that)

 

[BoomStick]

I have a focal hana and have noticed that with my 20amp lg battery it can't keep up when it gets low. However, my 30amp vtc4 can still make proper heat when it gets low. It seems the higher amp batteries have an easier time dumping what they have left when they get low while the higher capacity, lower amp batteries struggle when they get low on volts. I'd rather have a battery that runs hard all the way to the end. Next purchase will be 30 amp'ers even though my device is limited to 12 amps of output.

 

[Sean Di Rienzo]

Yeah, I feel extremely duped. I own 3x of the 6amp efest's. I was seriously at risk vaping at .5 ohms. How is this legal?

I have since purchased 4x Samsung nr25's from www.illumn.com. They are 20a (legitimately) and I will feel safe using them. Hopefully my boxmod will work well with them.

@Lighty, I have some china mech mod. It does have an adjustable contact I just find that to get it working with flat top batteries I have to screw it out to it's full length and it falls out sometimes.

 

[muth]

I've had that problem with a short contact pin. I have since parted with it, but I did consider looking for a longer contact pin.
