Anyone use ammo cases for the safe storage of lipos? Was considering getting something more than the cardboard box they sit in now. Didn't really see the need for a lipo sack.

I see one problem with using an ammo can and that is that all the lipos will be together in one place. If for some reason one did go off, it would take all of them with it and that could be an expensive problem.

If there was a way to store them in separate safe places, then that would be better. I always thought that a couple of cinder blocks would work well. You could stack them up and place one or more lipos in each hole. Then if one went off, the others would be just fine.

Since ammo cans are sealed (ones I have are atleast) I dont think there would be enough oxygen for all to ignite.

The hydrogen produced by LiPo cells would likely blow the box apart if it somehow ingited in the box which is not very likely.

If you do store them in an ammo box it would be best not to latch it.

I store my lipos in an ammo case, I am slightly concerned that if one goes up they may all suffer, but wheigh that up against containing a fire and I think its worth it.

Good luck

I've got several 50cal "fat boy" ammo cases laying around I got from a local gun show. They work awesome for storing lipos. My view is if one does go and takes the rest in the case with them, it's better then my whole house burning down as well.

I've also thought about the sealed cases and an explosion. Thinking about drilling several smalls holes in the top of the lid. That way the pressure and smoke could escape, but not the fire.

This subject has been discussed ad nauseum for 3 or 4 years over on the RCGroups batteries and chargers forum. There are several videos of different containment methods being tested.

Believe me without a safe venting method you do not want them in a sealed container if they go off. That being said the chances of them going off while sitting idle is almost zilch.

Go over and do a search and you'll see how much energy is involved.

Hydrogen also burns at some incredible temperature like 3000*F so you can for sure kiss any other packs goodbye if they do go.

I personally keep mine in a woodstove that rarely gets used so if in the very unlikely event a cell should go off it will vent out the stove pipe. I also charge questionable packs in there after removing the storage packs of course. That way I don't have sit around with my thumb in parts unknown waiting to see if it's going to go off. Watching batteries charge is almost as exicting as sitting around waiting for a car bumper to rust.

Guys the safest place for a lipo is on a concrete floor, away from combustibles. And when I say away, I mean like 2 feet away. Lipos do not explode, they simply vent heat and sometimes fire. Think of them like a blow torch. You can light a blow torch in your bedroom and easily not burn your house down, just don't lay it on your bed and keep it away from the drapes. Same thing with lipos. Use your head and you won't have an issue.

I wouldn't really even worry about it. The newest generation stuff pretty much requires you to do something like pierce the cells with a conductor like a nail or way overcharge them and most chargers will not do this. I've seen a video of a guy taking single cells and hooking them up directly to a 12V car battery and even some of the cells he did this to wouldn't catch fire. They just puffed and vented. While Hydrogen does burn at high temps it also requires something like 1000*F to ingite so a spark or flame needs to be present. No they don't explode but any sufficiently contained conlflagration (rapid expansion of gasses)is potentially explosive. Gunpowder doesn't explode it burns too but look what happens when you put it in a gun.

Now days it's most likely to happen during a severe crash. I mean the kind that virtually everything gets smashed to pieces like the proverbial lawndart into the pavement.
