18650 battery safety (moved from the the DAVINCI IQ thread)

Hey there! I did want to jump in and correct you on one thing. The Ascent did have 2 18650's as it's power source. The IQ battery is located next to the heater and is separated by several layers of insulation, the aluminum shell and the internal cage it'self. Also the battery dose have room to give off heat and vent. Air is allowed into the battery casing from 2 locations. 1 At the bottom there is a small gap in the hinge that allows air to flow in and out. Also if you look at the battery door from the top of the device there are gaps around the door that allow for air to flow in and out even when the cap is closed.



Great response and great information!


Great information share! I'll try and answer all of your questions as best I can. I answered a few of them all together so please let me know if I left anything out.

1 - Yes we did run stress tests to see how the IQ and the battery held up under extreme conditions. For those who don't know we are based in Las Vegas and have access to some warm conditions throughout the year. We did tests with the IQ running on max temp 430 with no shut off timer. So the unit would turn on and stay on at 430 and run until it was dead. No venting issues raised after this test

2- We did these tests with the batteries that we chose and with several of the other top batteries that we considered before making the IQ. For example we did this test with the Sanyo Battery that is currently provided and with a Samsung, LG, and MXJO batteries of the same AMp and mAh rating.

3 - We took several steps to protect the battery from the heat in addition to these tests. As I mentioned above Air can pass into the battery casing from the bottom hinge near the bowl and there is also air gaps at the top near the battery door to allow more air to flow in and out of that area. The bowl and battery are also separated by insulation, the internal casing, and the external casing. So there are quite a few layers in between.

Greetings everyone,I have just purchased my first dry herb vape,the davinci IQ and feel a concern regarding battery proximity to oven,the battery as supplied,no branding states: do not exceed 212F ,ok and the unit begins to operate as we would expect at 350F! and travels unto 430F with millimetres only between the oven and the battery!!,now I am not a chemist scientist electrician not a technical minded man so it is my intuition that calls me to alert,what sort of insulation can at the aforementioned proximity keep the battery below 212F? and after use it is impossible to remove the battery as everything has expanded,..seems marginal..like at the edge of the cliff

So what I do to avoid possible risk of meltdown in my IQ is to rotate through multiple 18650 batteries. At the 1st or 2nd heat levels it's not too bad, but when I'm at level 3 or 4 once the ten minute timer shuts her off I pull the battery, set it off to the side to cool, and put another one in. My IQ came with a Sanyo NCR18650GA 3500mAh battery, and for spares I'm using some LG HE2 2500mAh ones. They are available for about $6 each or less. I never charge the battery using the internal IQ charger, takes way too long for me. I use an external 4 bay Lithium Ion charger than can charge four 18650s at 1A each (or 2 at 2A each).

Bonus of having 5 batteries is I can go out and have extended sessions with friends without having to worry about charge levels. Also by not cooking the batteries at high levels for several consecutive sessions that should maximize battery performance over the longer term.

If your battery cannot be easily removed from your IQ after use I would contact DaVinci support, my batteries always slide out easily once the door is opened. Might be something wrong with your particular unit.

Hello gusy. I have Da Vinci IQ from couple days and it`s have been very hot to me :/ Is there a chance to breake the temperature down using some specific model of battery ? In this thread someone saids that Samsung 25R is a safety choice...Using this battery temp. will be lower or same when using orginal battery ?
I don`t give a f.... of capacity. I need to cool down this thing ! :/

EDIT. I found some information on other sites " For example, the LG HB6 is rated for 30A continuous and can easily be used at 40A. It is the lowest temperature battery vapers can buy. This seems like the perfect choice! But, the tradeoff you have to make for this high current rating and low running temperature is capacity. The HB6 only has a capacity of 1500mAh. This means that you will be changing batteries a lot more often than if you used higher capacity batteries."
So the LG HB6 is gonna be be the coolest battery for Da Vinci IQ ?

It's hot becaue the unit is small and contains a heater running at close to 200°C. Heat has to go somewhere and the entire shell becomes a sink. If you want your device to run cooler, lower the set temperature.

"Once the door is opened" is the issue. My door also does not fully open when the unit is hot. If you want to remove the battery from mine after a session (which I do), you have to remove the flavor chamber first; then the battery door will fully open.

But it`s hot even when i`m using first of the four sets of temp. Ofcours not immediately but after a couple of minutes. After some minutes i can`t grab this vape and hold tight for long time because is too hot :/

It might be better to go back to the IQ thread. But, "too hot" is a relative term. My wife can grab things right out of the oven with nary a peep. I put on a silicone glove and use tongs. Each of us has some level of tolerance as to when something is uncomfortably hot. I find if I put the vape down in a session and do something else for a minute, when I pick it up again, it sure seems hot. Uncomfortably so. If I keep it in my hand the whole time, not so much.

As @KeroZen implied, it's a hot vape.

You are correct here, if you keep it in your hand the entire time, the heat is dissipating in your hand, therefore relieving some of the heat. Not only that, but you tend to use it....hence forcing airflow through the vape and once again cooling it.

@OldNewbie - have you tried to push down the flavor chamber before opening the battery door? I know that some units are more finicky than others, but this seems to do the trick.

I realize that is a realtive term.... Before IQ i have ASCENT and it was a little hot but I was able to hold him all the time. With IQ i`m holding it all the time but after couple a minutes (i dont know aby ~10) i can`t hold him tight and i must turn it into my hand :/ I see on onther pages that some people put in battery with high Amp 30A like LG HB6, maby This may help, though

The metal clip at the top of the chamber (mostly between the flavor chamber and battery) popped off fairly quickly after I got the vape. I popped it back on and haven't really had a problem with anything so I thought nothing more of it. If that holds down the flavor chamber, it makes sense the door issue might be resolved with a push rather than a removal. I'll check once I get off my "sabbatical".

Hi,
I bought this IQ a couple of days ago. Just to be clear... is it normal to feel the surface very hot after a couple of minutes? I track the temperature with the app and it looks fine, but I don’t want it to explode on my face! I trust in da vinci’s tech, but this post really concerns me.

A friend of mine received the IQ as a gift. It gets hot and now she's going to return it. I retired my ascent after getting the Solo 2, nuff said!

New full-page advertisement from LG Chem on the back of the Wall Street Journal's front section.

It tells us to "never handle lithium-ion battery cells" and to "stay safe". The copy says:
LG Chem will not sell 18650 or 21700 lithium-ion attery cells to consumers. 18650s and 21700s are not consumer batteries but are "bare cells" which must be incorporated into battery packs with protective circuitry.

Bare cells are only safe for consumers when hidden inside battery packs. Some companies have designed products such as vaping mods and flashlights that require consumers to handle bare cells. These products place consumers at risk of serious burns.

Stay away from any product that requires you to handle a bare cell and Stay Safe.

DON'T BUY IT
DON'T SELL IT
STAY SAFE

My guess is it is part of a litigation strategy to try to keep lawsuit losses down.

I dunno how safe are batterypacks :D... A friend of mine got injured seriously on an uphill ride with his e-bike,the battery caught fire and started spitting nasties all over him,no to mention he inhaled a lot of that stuff.. He is still alive but has bad burn scars,going to feel awkward with his pants down for the rest of his life ,both his legs are bold on that areas now... ,lol. Maybe he should sue them and use the money for hair grafting.

Litigation avoidance, yes. It also justifies the minimum order quantities of 100 pieces. You know us 'consumers' - will - get our hands on them. We always do! :nod:

I also find guns to be very safe. Just not the idiot near one.
