    RE: Lipo Fire in Garage

    Here's a possible solution: Found this at the local Home Depot. I'm thinking of lining it with ceramic blanket material, adding a few dividers, and the lid already has a 1" area to add sand bags.

    Any suggestions for improvement?

    I like your idea on the toolbox. I would add a vent though by drilling a hole or two. I am sure the lid isnt totaly air tight, but from the information I am reading I am seeing that unvented causes more damage than vented does.

    I'd like it if you would post pics of the mods you do to this box.

    Can you post the SKU to this box? for searching purposes.

    Regarding vented versus un-vented boxes, it's my understanding that, without oxygen, the fire will go out. So, I would think that a un-vented stroage box would br preferable.

    You can try amazon, ebay, or a hunting fishing store. I have a Gander Mountain near me and they usually have them there.

    The ammo boxes that I have form quite a tight seal. Given the amount of gas and heat that can be generated, a small vent hole will not let the pressure build up. As soon as it starts venting, little to no oxygen is getting in anyway.

    I had just saw a picture the other day of a guys garage that had an unvented charging box, and the results were much worse than had the battery just burned. The explosion that happened from the build up of pressure cause quite the damage in his house attached garage.

    The LiPo will vent a large amount of gases when burning up, and from what I am reading, will need to vent that out somehow. See here http://www.utahflyers.org/index.php?...d=21&Itemid=28 He does a lot of bunker tests and shows the different things a LiPo does during a fire.

    I couldn't tell if the charger went first or the lipo. Really doesn't matter. This incident just causes me two solid days of grief. I had to completely gut my shop, and hand clean ever single item, scrub the walls and floor and all tables, because of the thick black soot covering EVERTHING!. We are fortunate this didn't end up like several others whos houses burned down.

    This should serve to others as a wake up call to make sure that you NEVER leave a charger on all night and NEVER charge your lipos in the jet.

    Andy
    Thank God the house didn't catch. good thing they were on the concrete floor and not a bench. i do on very rare occasions leave nmh on charge while unattended . i don't leave them on over night anymore. I know a guy that had his house burn down . they were home asleep but got out . the wife eventually pasted from lung injuries some time after. i also lost a brother in a fire in '80 so i'm extra careful with that stuff .

    RE: Lipo Fire in Garage

    I agree with the venting. I think they should be vented. When you buy a lipo charging sack/bag they have 3 buttons on the top
    or a strip of velcro to close the bag. They are well vented.
    This is what I did with my charging ammo box. I drilled a 1/4" hole in the top and a larger one for the wires in the bottom.

    I friend gave me my Ammo box but I have seen them in army surplus type stores, I have left it sealed but must drill some vent holes, have a spare one which I am going to modify for charging purposes.

    RE: Lipo Fire in Garage

    You gotta remember the main purpose of a box/bag is to contain the initial roaring flame that only comes out for a few seconds and would light near by objects on fire. You're just making a bomb if you use a sealed box.

    RE: Lipo Fire in Garage

    So it looks like it should be an ammo box that is sealed very well with compartments for each battery or better yet a separate ammo box for each battery.  Then vent the box to the outdoors so nothing indoors gets destroyed with oxidation or fire.  Hmm, are they more dangerous than a box of ammunition?  I thought they were just little leckies.

    I believe that Lipo's create their own oxygen, so trying to lock them in a air tight box will only create an explosion. You cant smother it.
    You will need to vent the box.
    Someone mentioned venting outside which sounds ideal.

    RE: Lipo Fire in Garage

    I store lipos in a vented ammo box. Do you think its possible to build a second box with a particulate filter. Place the ammo box in the secondary box and close it. Ammo box contains the flames and heat. The secondary box filters the venting lipos. Any thoughts?

    RE: Lipo Fire in Garage

    Awesome thread with brilliant ideas, from Todd's self extinguishing melting sand bags to the above secondary filtering box....etc.
    But wouldn't it be easier and safer to just go with LiFe? without the risk? and without a regulator for most rx applications?

    RE: Lipo Fire in Garage

    Life wont work in every application. I dont believe they have a high enough C rating.
    Im pretty sure they wont work in high powered electric jets.
    Ive played around with them some and am still on the fence whether or not I like them.
    They might be fine for RX batteries, but I dont know about anything else.

    Very true, these ones are only rated at 20C and are meant for ECU and RX.

    RE: Lipo Fire in Garage

    Like I said before, they are 1/3 heavier and bulky. I think the C ratings are fairly good on some LiFe's. They also put out 3.3 V. instead of 3.7. They can make a good motor battery but there is a loss in performance, size and weight. It is likely not the answer to high performance jets (or anything else really) They do work fairly well though, just not as well as LiPo, 20 C is fairly good but not great. Things do improve over time though if things get forced. It is already illegal to ship LiPo's over borders on air freight. Maybe the shippers need these fancy explosion containers too. I will use mine for putzing around on the glider. Maybe even three cells some day in something else if I can get some cheap 1200 mah ones.

    HI Barry,

    How about a quantity discount? I'd need at least 20 to switch out.
