Is something like this suitable for storing charging Lipos?

Is something like this suitable for storing/charging Lipos? I'm a bit concerned because it doesn't mention anything about being fireproof.

lol, who knows... what I do know that I'd watch like a hawk someone walking into the wilderness with a backpack and an ammo case...

[G+_Phorest Sherwood]

I'd say no. The plastic would melt. May beta metal can, but still use the limo bags inside.

[G+_Michael Heinz]

Yeah, you're probably right.

[G+_610GARAGE]

This ammo case would work. Just be sure not to place it on anything flammable, or put bricks inside to lift the batteries off the bottom.

Of course plastic burns!  Get a metal one.

[G+_Taylor Graham]

Ammo cans are cool, just dont close one while charging lipos inside. A lipo explosion would blow the ammo can open/apart, which is probably worse than the lipo exploding on the ground.

 

IMO, just keep some sand and a fire extinguisher nearby. Sand will stop the reaction immediately.

[G+_Taylor Graham]

There's a video online of someone doing a test with a closed ammo can and a 3" vent hole. Even a hole that large wasn't enough, it blew the top off of the can.

It's actually linked in the thread you posted above, but here's the direct link http://www.rcgroups.com/forums/showthread.php?t=355739

It was a 6000mah battery though.

[G+_Taylor Graham]

oh hey! i didnt remember reading that, that sure would do it.

Think of what one of those plastic encased solid packs would do.

[G+_Eddie Foy]

Don't abuse your batteries.

I see no reason for them unless you are bringing home a damaged battery.

They don't 'just catch fire' or 'explode' for no reason.

[G+_Michael Heinz]

Still not a guarantee, Eddie Foy.

All I know is, don't go carrying that around in public.... I can just see Fr. Robert Ballecer, SJ? getting stopped outside his house carrying two drones and an ammunition case :P

[G+_Ben Reese]

Are you suggesting the park isn't the place I should be cleaning my guns? What else am I supposed to be doing while the kids play?

[G+_Timothy Hamlett]

Ben Reese? ummm.... Wardriving?? ARP cache poisoning?

[G+_Michael Heinz]

Wardriving with your rifles and ammo cases? Timothy Hamlett , are you trying to get us put on a watch list?

[G+_Timothy Hamlett]

lolol

The biggest problem is newer ammo boxes are not made so much to transport lots of ammo in one container ie military metal ammo box which is meant for reusable shipping containers, While the ammo cases like you're showing are meant for storing lots of ammo over time so they are sealed to some some degree so the ammo last longer.This means the box could act like a thermos or like an oven. iIf you intend to store and carry Lipo packs in a container not designed for that purpose first the box/container needs to be lined with a bag thhat at the end of this setup can be cloesed and removed so look for a strong cloth bag that can be closed around the container so you know it's big enough.Next try key word try to find a fire retardant/block to treat the bag very generously, they're getting harder to find for some reason. After you've found the right bag and treated it tend to the box with 2 modifications first port your container so if a lipo pack seal breaks and that pretty pretty fireworks display happens there will be a lot of gas expansion at a very high rate especially if several packs are stored within so the container needs to allow an appropriate release of expanding gases which is calculated by the structural integrity of your container, the expansion volume of air pressure, altitude, and heat energy that would be released by per pack calculations and so on which is why you want a good cloth bag at proportion to the container that was given earlier. Feel free to think before you mod and consider where you are keeping this container and port appropriately for that location, and use some common sense and don't stack or set your container around flammable items or enclosed spaces like in your closet filled with clothes for you young people out there nor around pressurized flammable gas lines or containers for you adults that thinking a garage is ideal yet forget about the bbq grill or lawnmower, weed trimmers, cars or in wall gas lines which are the most common of the bad locations that people have used and regretted it.  Second is to treat the inside of the container with a layer of fireblock caulk or foam, easily available, so any petroleum based plastics or wood including wall studs. After you've completed that then you want to place the bag in sand ideal with one of mix for explosive containment is %40 silica or quarts sand and a %10 absorbent crushed nonflammable media %20 to %30 crushed porcelain for it's specific heat value and %5 crushed AND baked kitty litter, preferably unused, and the rest in various crushed hard stone, river rocks, and if you can get them, gel fire stop granular pellets designed to turned to a fire smothering slim that expands when activated downside is most give off CO and CO2 gasses which are heavy gasses that keep smolder from getting O2 for flaming back up and mostly only available to secure grade labs, so second choice is see if your local Fire Department can spare a cup of the powder they put down at car wrecks with spilled fuel at the scene. Yeah play sand can work but this mix with only the powder from the Fire Dpt. should be a powder the rest in no smaller than common sand grains, which in this and other type mix will prevent molten spillage or reduce it which is something to consider. Now take your sand or fire/chem mix and after placing bag in box put your grains of sand/mix in the bag about 1/3 to 1/2 way full a 1/3 is sufficient in most cases make a cardboard with slots tto hold your individual lipo packs, just need scissors, cardboard and a hot glue gun make it a family project and get your children to do th work for you.3:)  Add horizontal flaps at the bottom of your cardboard box and vertical wings along the outside of your cardboard box then place cardboard box inside bag in container on top of the sand/mix that is at least 1/3 of your container in bag and fill rest of container with as much sand/mix as possible around the outside of cardboard box and place lipo packs in an individual lipo bags and place each lipo pack in their bags in the slotted sections inside the cardboard box close bag without spilling sand/mix close lid secure and just try not to store lipo packs long than a month or 2 without checking their charge and condition preferably not lower than a %20 charge for any rechargeable batteries. Now sand will work but the mix should contain a lipo ignited discharge and stop a fire inside a car or house with carpets. Make sure you have as much sand/mix around the cardboard box as under it or more so if an ignition occurs the cardboard burns and sand/mix collapses in on submerging all of the lipo packs completely keeping them in center of container. One last word of warning if a lipo pack ignites while in the box slotted or not do NOT try to remove that lipo or any of the other lipo packs from the box or move the box from any location and best not to remove lid until box is in location for lipo use or storage and not inside of a vehicle but still most important do not try to remove a burning lipo or save the other lipo packs from a box with burning pack inside let the boxx do it's job. That may look like just a bright fire but it is a chemical reaction that is creating plasma not flame just let the box and sand/mix do their job and it won't be safe to mess with for a long time infact 5 packs or more might require a sensor to see if it has cooled down enough to handle within 24 to 48 hrs and never by hand. In your case with 4 or less lipo packs better to just buy a commercial/consumer container to carry off to places so you can toss off your body if ignition occurs while holding it and make the container for home storage. I don't think writing Ammo on the side is a bad idea either   ;)

For a flame retardant, couldn't you cut some ¼" concrete board (like used under tile flooring) to fit the bottom and sides? The seams could be sealed with grout... Just a thought.

[G+_Michael Heinz]

At the moment I've settled for storing my batteries in my (unused) fireplace as the safest place in my house after the oven; while they're charging I keep them in a lipo bag laying on a ceramic tile.

As  the son of an "Architect" or so I'm told every time I'm trying to invent something structural and I try to explain my design to him. I can also tell you that you would think so and if it was just flame maybe, but again you're dealing with Plasma not fire. In building materials concrete board is not really even the concrete normally comes to the mind of most people think. As even now he's telling me what I know and trying to write so I'll repeat what he's telling me, well paraphrase. So first think about what "Cement" is for the benefit of others so don't think I think I'm being an a** to all the adults out there. Cement is really nothing more than varying sand, clay, water and rock/crushed gravel. Essentially the water absorbed in the mix makes it useable as cement when used  on the ground the top can bake and appear as a  stone structure and in the ground is where it is more commonly used also for the diy concrete mixers. Now concrete is simply put a glue that binds cement with ash and other goodies. Concrete made for fireplaces and so onis made by a special clay which it why they have a slight natural red tent and also tend to crumble if not for the mortar used on them the stuff put in the new tower is a company secret. Now concrete board is given fibrous goodies and a paste on top of glue that will trappes moisture stopping some mild fluid penetration (no jokes ) So this is also the problem that made the twin towers collapse. Even though the structural concrete support columns were up to fire resistant code even surpassing them, it was the difference in heat of a fire that could happen and be fueled by flammable material within a building and the heat being fueled by jetfuel is  a way completely different beast to deal with. Unaccelerated building fires burn around 1,100°F and jet fuel in a building burns around 2,500°F and even 4,500°F or  close to 5,000°F when you calculate the high constant wind acting like a furnace air pump. Metal smelters are playing around 3,000°F to make bronze (He's also an artist) Now when it comes to "PLASMA" which is not flame but a physical state of being as matter for ei solid liquid gas then comes plasma. Plasma van be in this case 100,000°F and the extreme a few billion °F. Yes I've visited and been visited by the Fire Marshal relating to a project or two but always ended without fines and everyone mostly okay. So all concrete will have some moisture and if a good size pack goes and other packs are present the temperature gets so hot so fast all moisture turns to steam before the gases can escape the concrete structure thus making the concrete explode so not only will a lipo pack burn right through the plastic or metal box but you will also have small grain to quarter size bits of concrete flying around(based on a science experiment with a great and fun physics teacher using the sun, mirrors, and the season of winter during a lesson about parabolics) good times.3:) So the container build I gave earlier is one of the best ways to store a mass quantity of lipo or explosives because the pressure of expanding gases is transferred and that's why the bag and container prep is used and the mix will make a cast of molted and solid material allows the heat to escape slowly or slower which is what you want  and if that ever happens you'll end up with plasma glass and once you safely extract and polished you have a souvenir that has a lot of fan base you can sell it at certain shows for more than the cost of the lipo packs and hopefully any damage to property and possessions. So still better to carry a lipo bag/pouch for 4 or less and the container build for storage for long trips to use more than five large lipo packs and to store your lipo packs or explosive materials you might have for what ever science experience you might have planned Fr. Robert Ballecer, SJ  would you disagree with the concept or have a better cost effective safe way? In fact if you contact your local fire department Fr. Robert Ballecer, SJ  and Bryan Burnett  and ask for permission and safety coordination to demo the lipo bag and Container instructions I gave as well as different accidents and proper ways to deal with immediate first aid other issues when dangerous mishaps occur in the name of Science and safety of course. 3:)
