Battery Charging Bag

[zapped]

Using anything outside its intended purpose is a risk. Again my knowledge of batteries and chargers is only cursory but I do know that Li-Po and Li-Ion batteries have different chemistry's.

Maybe the Li-Po batteries charge cooler as well? I know my AW IMR's get pretty hot in my Provari when Im chain vaping for a few minutes. Logically, the Li-Pos probably operate cooler given their purpose of extended use and high drain in RC vehicles.

If the bag is only rated for 90 degrees and the batteries and charger are putting off 110 degrees, sounds like a recipe for disaster.

Are they putting the chargers inside the bags with the batteries? I believe that is the issue we're talking about here.

Excellent point. The Li Ion batteries that we use in vaping require that they be charged IN THE CHARGER.

It's becoming clearer to me that the charging bags in question were NOT meant to have chargers IN THE BAG. It's also becoming clear that the bags were not intended to use for charging Li Ion batteries.

Li Po's and LI IO's are 2 different batteries. The Li Po's are inherently unstable. It has much to do with the "gel" style internals. Our LI ON are calm in comparison. LiPo's are normally capable of 20 to 60 C charge and discharge rates. It is normal to discharge a 12 cell, 50Volt, 5000 mah battery in less than a 10 minute flight, and recharge the battery in less than a half an hour. Our LiOn's are much closer to 1C. It takes me 24 hours to discharge a single 2400 mah battery and 2-3 hours to recharge it. It is always recommended to charge LiPo's away from everything, many will charge their batteries in ammo cases. I paid in excess of $500 for my r/c charger, the charger from Provape is $16.95, doesn't that tell you something?
I read something recently that the odds of having a Li Io battery have an internal short are better than 1 in 10 million, (might have been 1 in 40 million), that is to have the battery catch fire. They are designed to not explode, even the cheap ones have a "blowout" plug to prevent that. If there really was an eminent danger of exploding, do you think they would encase them in a metal case? If your battery ever exploded you could own the battery company. BTW, LiPo's are usually incased in a plastic cover, I have seen some great fires, but no explosions.
I am not an expert, but it seems as though people are confusing the inherent dangers of LiPo's with LiIo's.

Unknown.

Although it appears the RC people may be using completely different types of battery sets.
But the flashlight folks are using what we are using as far as I know.

Well, I've been putting my chargers inside the bag for years.
I've had no problems in doing this, first with 18650s and now with Twists.

But I never do more than one battery at a time, so maybe that's a factor.
And I still think that using a quality charging bag might have something to do with it.

Anyway, this is new information which I have never before heard in my time on this forum.
I will continue using my liposack for now but will be checking for how much heat I can feel during charging.

How does a "quality" bag with no ventilation different from a cheap bag with no ventilation? Unless the high quality bag dissipates heat as well as holds heat in as it is made to do?

I don't think they are necessarily made to hold in heat so much as made to hold in fire.
