Summer flooding

So if heat is so bad for LI-ion batteries how come the hybrid cars aren't bursting into flames in +100° weather. The auto makers must be using better batteries than us.

You have been around awhile too. Maybe a device maker will install a liquid cooling system in device.

How to Prolong Lithium-based Batteries - Battery University

Lithium-ion suffers from stress when exposed to heat, so does keeping a cell at a high charge voltage. A battery dwelling above 30°C (86°F) is considered elevated temperature and for most Li-ion, a voltage above 4.10V/cell is deemed as high voltage. Exposing the battery to high temperature and dwelling in a full state-of-charge for an extended time can be more stressful than cycling. Table 3 demonstrates capacity loss as a function of temperature and SoC.

Lithium Ion Batteries Can’t Stand the Heat | PluginCars.com

To combat the extreme temperature effect and keep batteries within their optimal temperature range, automakers use thermal management systems relying on either air or liquid cooling. As the EERE data shows, liquid cooling is generally more likely to preserve a battery’s capacity than air cooling, though performance variations will occur depending on how well a battery management system was designed to control temperature. According to Ford, the liquids used in cooling systems can retain a temperature for a long time, which contributed to Ford’s decision to use liquid cooling on the Ford Focus EV. Ford has also used air cooling on its hybrid Escape and Fusion, as have Nissan and other BEV manufacturers on their vehicles.

I left my tank in my truck last winter and at 10 degrees with 50/50 it would not even vape but one little puff then burned the wick.
Yeah we vape "antifreeze" but it gets thick.

PG is used as a component of anti freeze in the environmental safe versions.

New little thermo coolers to wrap around our tanks?

Yeah I know that and vape it. It helps me to stay cool in the summer heat too
It is also in food products, inhalers and cough syrup, toothpaste, etc.

It is in my lip balm. Considering I have pg and vg stocked I just make some lip balm with a little menthol. I like it.

When I go to the beach, I have a little cooler with an ice pack. Wrap a towel or washcloth around the mod, pop it into the cooler and the towel protects from any condensation plus the added benefit of catching any possible leaks. Also it helps to insulate the PV.

Good luck!!

Maybe I'm just lucky, but I've been using Kayfun 3.1 tanks for about a year now and haven't had any of the leaking problems associated with hot or cold weather that were way too common with 'bottom coil factory built' atomizer heads.

I use one of these...Thermal mug, just large enough to put a mod, juice and tank in. Keeps cold for 24 hours, cost less than 20 dollars and who would steal this out of the car!

I use the same thing, but do have a problem IF the device has been sitting in extreme temperatures and not being used. Also, when I had it sitting on a table and the sun was beating on it directly, it gave me problems.

I can be outside and using the kfl and no problems. It seems that when it is not in use, that is when things start leaking. Now that I am thinking about it, since it doesn't leak while using in extreme heat, we are probably keeping the liquid from doing whatever it does by vaporizing the excess.

I live in high humidity and heat 9 months out of the year. Best device for this. Is a REO.

Again, guess I'm just lucky, but the only time my KF's (5 that I use regularly) have leaked was from the air hole. Since I have found the 'right' fill method that has ceased to be a problem. That said mine are seldom exposed to direct sun light but living in North Texas temp variations of 30-40 degrees are very common.

That's where mine leak from. The air hole. But only in the conditions I noted. When I first got it, it took me a while to figure how to fill correctly to avoid that leaking. Now that I have, the only time it leaks is when overheated or while flying and I don't have it upside down. I Like learning all the little quirks of my devices and mastering them

In addition to all the good suggestions for keeping your set up cool, I would also try opening up your airflow during the hot summer months.

Just don't leave it in the car...
Battery and juice will have issues

I made this same post almost 3 yrs ago 100% vg was not match for 103° the enormous response of recommendation was an igo-l. Still use my igo-l frequently was great suggestions.

Jimi D nailed it, for todays best option to heats; ya a Reo or that smokeless owl, bottom feeders are killer in heat no leaks and plenty reserve tank..

I still use an IBTanked carto tank and continue to use it in hot weather. It doesn't leak or flood regardless of weather. We have a high of 102º forecast for today and the thermometers should reach that point about five hours from now. Right now it is 90º at the garage workbench where I'm vaping.

A carto tank is going to heat up plenty if you use it much above the 90º ambient temperature mark. That heat will eventually travel right down my solid stainless steel mod and will eventually combine with battery discharge heat to warm the battery to well beyond the elevated temperature threshold of 86ºF. I suppose a wooden bodied mod might resist heat transfer a little better.

Consider that I'm using a carto tank and I'm only vaping 7 watts. I wonder how hot my rig would get if I was out in the +102º garage this afternoon vaping away at 20 watts, 50 watts, or 150 watts?

I just found out the hard way. I use to be able to leave my nautilus tank in the hot car all day and it wouldn't gurgle or leak, you just had to remember to hold it in front of the A/C vent to cool off the drip tip or suffer through a burned lip later on. But I could never leave my Aerotank in the car even for 30 minutes would make it flood, but I tried leaving my new Subtank in the car while at work the other day and sure enough I got back to the car to a sticky mess that had run down my vaporizer but fortunately inside of the cup holder so it wasn't all over my carpets or anything like that. Oh well... Kangertech IMO just can't handle the hot weather and is why I used to switch to my Nautilus each summer so that I could just leave it in the car even on days that were 118°f.

Can't really recommend leaving anything with a battery in it in your car for an extended period of time on a hot day (even a cellphone might start acting funky if it's in direct sunlight or something).

In regards to the cooler, that's not a bad idea. A cooler does a pretty good job of actually staying "cool" even without ice in it. You might be fine putting your backup in a cooler sans-ice (I'd be worried about ice melting, water, etc., which would be a whole 'nother issue on its own).

Ice substitute serves to keep the juice--and the batteries--cool, too. You don't have to get a whole bunch of packages of ice substitute; all you need are 2 or 3: 1 to put in the cooler and 2 for backup.

My husband has ice packs in a cooler, and his setup and juice in a gallon ziploc baggie, so it doesn't get wet

Why'd the Ford Focus EV get a link and the other vehicles not? Huh..
