LiPo Bags anyone else using them?

[NingyoBiruda]

Hi, everyone

I just saw a thread about a battery catching fire and I have noticed a few. So I was curious, is anyone else using fire bags? I am a long time veteran of RC cars so I already have them. In RC it has become a standard use them. Granted batteries used for RC have more power (average 8.4v-16.8v 5000mah). I use LiFe (Lithium Ferrite) batteries cause they are safer but I have had one catch on fire before.

So...
What are your opinions. should fire bags become a standard in this industry as well?
Just random thought.

just a bump to keep this alive ... seem to be a few reports of issues lately (well, I've only been here lately - maybe always). Would welcome some discussion on it.

Well here are some test videos of good and bad lipo bags. just for reference.
BE CAREFUL which LIPO bag you buy. Watch the test videos.
Look at the fire coming out of the back of that one bag. Another bag melted and one just blew open. I wouldn't trust any bag that hadn't been tested and proven to work with the size packs I intended to use in it. A video of a LipoSack test is included for comparison.
You can find a bunch more tests on YouTube.

LOL. No. I'm using cylindrical/replaceable IMR 18XXX series batteries with a Nitecore Intellicharger i-4 battery charger which should be left in open air for safe and air-cooled battery charging. Sticking the Nitecore in a safety bag would result in high temperatures that could reduce safe battery life and result in a fire. Cheap Li-Po eGo batteries are a different story...

 

[MoBayRasta]

yzer I totally agree with you. I do use lipo bags for charging rc battery packs but have also had one catch fire.

I'm into RC too. Here's my buggies..... Mugen MBX6 ECO and Xray XB4. I have LiPo bags but never use them for ECigs.

 

[BigCatDaddy]

I've got one and I use it on every charge, regardless of battery type.

 

[Bunnykiller]

never used one... no need to if you do things correctly

 

[karateka817]

Never even thought of getting a fire bag...

i totally agree with this statement,,the batts still get hot in open air ,what more if they are in a non venting area

I use a small steel container with latching lid, because I got it for free. It's kind of like those locking money holders. I always thought putting my charger in a bag was a bad idea. (Heat buildup?) The box has enough room to allow air to move freely, might still drill a couple air holes in the lid. I figure if I ever did have a major issue with charging a battery, a steel box should be able to keep it well contained. Hopefully I'll never get a chance to test that.

Charging any battery will generate some heat. Sealing it into a bag contains the heat...

But.

Safe practices should be followed. Inspect the battery before charging. Don't charge unattended. Charge in a safe place.

I re-purposed a pair of large ceramic ashtrays. (The have some sentimental value ) They're about a foot diameter, and stack into each other. So I have about 4" of ceramic between the "charging station" and the table.

I think you'll find that most of the "exploding battery" stories wind up being user error. Wrong charger, wrong polarity, wrong output current. (Put an ego charger to a 510 stick and wait for flame....) Yes, there will be the occasional failure. Ever hear of an Iphone or laptop battery burning? Or a 747 battery pack?

 

[2naphish]

use one for everything..cell phone,batts,ego's. have since i first heard of an explosion...

Yes a LiPo bag will contain some heat but not enough to damage a battery. If you follow basic rules of charging battery you will be fine. Always let your battery rest if it warm from use you need to let it rest. This is before and after charging as well. Also never leave a battery unattended. Make sure to periodically check the battery.

Pacrat315 that sounds dangerous if you are locking that lid. If gases can't escape you just made yourself a grenade, shrapnel and all.

Beautiful cars

Here is my collection. HPI 5B, HotBodies D8 Hara Edition, Losi 22B, and a old Kyosho Optima

I've never used a charging bag. I've been concerned about the bags retaining any potential heat due to a lack of ventilation of air flow within the bag. However, if in your judgement they are a good idea, then by all means use one.

I charge my batteries on my stove top, a flame-resistant surface. An alternative would be in a metal or heavy pyrex baking pan container.

 

[NingyoBiruda]

The issue I have with just seting batteries on even fire-resistent surface is sometimes batteries will launch like a rocket. Making it pointless.

Nice cars. That 1/5 scale is a beast!

The one I have is far from air tight already, but like I said, might add a hole or two.

I have a Nitecore i4, and mainly use AW IMRs, so they are pretty safe without a bag, but I still have a couple of eFest bags, handy for travelling, put the boxes of batteries in the bag
