Anyone worried about their Li-ion batteries now?

Have very little concern even though I have at least a couple hundred cells.

just got one of those crappy fire brand went boom in front of me lolz.... but my body still in one piece

My NUBM44 uses a 4.5amp SXD and 2 efest 26650 IMR cells and it's draw is 3.4 amps, that's no problem, now after a good 3 minute run the 26650's can feel a very little bit warm, but not hot at all.

If you use a boost driver for a high output diode such as the 44 then you will draw 7 amps + and that's a lot for a single 18650 IMR, they can do it but it will get warm faster and is harder on the battery.

p.s. I've had lots of cells and never had one go boom.

Welp I had used a unregulated mod works good great flavor, but one day I was washing my car and the mod slipped down my door cubby and when I finished the wash the damn thing had been on and sucked the juice dry and melted the nylon between the coil post. The batt. were real warm to say the least.

I have only had one venting Li-ion and man that was enough for me. The lady in the article (happened down the road from me) according to local news sounded like she had some knowledge of the coil, mod, and batt. safety and issues. Man blew out her front teeth.... yowza!!

nah we should not.... E-cig are on a whole new level compare to Laser. E cig draw 20-50 amp so lol....laser user is no where close to that current draw.

This is starting to make sense now as far as battery talk to me. No where iv'e gone since I have gotten into lasers have I ever overheard a conversation on lasers. In the past month iv'e overheard a few people talking about rechargables batteries and I heard that #18650 both times and thought I actually found someone into lasers but no. I did butt in and asked what they were using them for and it was for vaping and yes now I understand the problem is they cant find a good lasting battery and they are also worried about recent explosions. I did mention this forum and the module mods for vapes and one guy actually asked me to write it down. I still don't don't don't think right at times, in my console glove box I had put a no name blue to give to someone when I bumped into them again and all I did was rap it in a sandwich bag

I would worry if I were drawing high current from my batteries, but not for what I'm pulling from them now. The highest current I pull is 6 amps from a couple of 26650 batteries in series, that's nothing for the ones I have.

I don't worry about anything like this. Batteries explode. It happens. But theres millions if not billions of devices now using rechargeable lithium batteries and a handful of them at most suffer a notable failure.

Its the media trying to make e-cigs into a bad thing. I've heard more cases of iphone batteries exploding than e-cigs, but people generally don't panic about iphones.

Good batteries, good charger and i don't worry. Use in Laser, vaping and high end NV kit. As above alot comes down to the user buying cheap batteries/chargers or using the wrong charger.

Its the same deal with these "hover boards" exploding stories that have been doing the rounds. There really is no problem if you respect your equipment. Not once had a single problem with a battery, neither have any of the people I know who vape.
Don not put them unprotected in your pocket with keys or other items than might cause a short.

It's certainly a numbers thing, and phones and such catching fire, exploding etc are also news stories once in a while. These are literally one in a million (or fewer) cases.

Perhaps about 1 in 10 million lithium batteries installed in devices blow up under normal use. This would mean 10 iphone 5-series exploded, a few hundred laptops caught on fire, and also a couple of e-cigs blowing up.

Statistically you're still more likely to get killed by a coconut falling on your head.

What I gather from this thread is that I shouldn't worry too much as long as I'm not using no-name cheapo batteries.

If you are able to tell a real brand cell from a fake one that could help - but there are loads of fake brand cells out there and some look pretty good at first glance. Just a capacity test will probably tell them apart though.

The core issue is that these batteries are just a lot of energy stored in a relatively small volume, so IF it goes wrong the results can be pretty bad.

This is not unique to lithium batteries though: nickel-cadmium batteries will also readily melt plastic enclosures and potentially set them on fire when short circuited... or they just heat up whatever is shorting them out to a point where that can start a fire. If you short a NiCd cell with a small steel wire you'll know what i mean (no, don't try that unless you want to walk away with some burns to your fingers at best).

At your age your never going to die, when you get old and realize you are going to die, then you will be more aware of what is hazardous and you will be less adventurous and take less risks.

Never stand or sit directly under a coconut tree, the tallest ones get up to 30m/98ft, you don't want to get hit with a coconut falling from that high.

I know a guy that works for Boeing and as you probably know they are now using Li-Ion batteries on the jetliners, he told me they are now using a box that will safely contain the batteries no mater what.

Events like that are always a result of Chinese bootleg companies-Ultrafire, etc.

Stick with the major brands like LG, Sony, AW, etc and you're not gonna blow up.
As an e-cig user, I hate how bad these stories look since its the user's fault for using an unregulated device and cheap batteries.

I'm quite aware of my mortality really. I do wonder how an e-cig manages to blow front teeth out when it explodes, without, say, ripping half your face of and blasting shrapnell into your eyes however.

As for the lithium batteries actually used to power the plane, those are are a couple of magnitudes larger than what goes into an e-cig or laser pointer.

The danger has to do with energy density and the possibility to quickly release that energy. Lithium batteries have an energy density about 1/5th of that of gunpowder and will release it quite quickly on a major malfunction. If it is somehow contained in an enclosure that ruptures at some point, you could compare the damage potential from a lithium cell tot that of 1/5th its weight of gunpowder in something like a pipe bomb.

Afaik those batteries didn't explode but did overheat and sometimes caught fire. This is problematic considering they are fairly large as they need to be able to start the APU on an airliner, which is quite a bit more powerful than any automotive engine.
