Anyone got a homemade one, what do they look like, all safety manuals talk about charging/storing your lipos in a fireproof box but i dont even know what that is. Metal just increases your risk of an accidental short?

I purchased a small fireproof safe at Wal-Mart for $20 bucks.

I'm using a military type ammo box. Not as good as a fireproof safe, but should contain a fire.

You would think that a fireproof safe would have a tight seal around the lid. But I am able to close the lid & latch it very easily even with the two 13 gauge charging wires hanging out. So I can only "assume" that any internal pressure would vent.

I monitor my charging and charge with the lid open. I only charge my packs in an open area outside. If I should ever see a pack balloon up or ignite, my plan is to just close the lid & leave it unlatched. The safe is more of a containment unit than anything else. I hope I never have to experience this.

by being "fireproof" it probably doesnt mean its airproof. It is more likely to mean that if there is a fire outside of the safe, it will withstand the heat to a high temperature before the safe melts and destroys the contents inside.

After seeing a video of lipo exploding / combusing whatever you prefer, i would not like to store it in a small box, because i feel it would either A throw the lid off or B cause a flamethrower effect through small vent areas (i.e. a small gap between the box and lid which would also be opened because of the sheer pressure inside)

A BIG fireproof safe i would feel a little more comfortable with, but it would have to be a stationary one that had a vent in the back to the outside to let any pressure of a lipo makes get out (would also help keep battery cool in a confined space whilst charging)

so is it safe to say that there is some confusion about how to charge lipos safely, all the warnings talk about charging in a "fireproof" container or safe enviroment, but no one is ever specific? Perhaps one of the lipo manufacturers/distributors can help us out here. At the moment I have an outdoor mains plug (my swimming pool pump) which is about 10m from my home and that is where I do the charging, but what about storing in the house?

when they say in a fireproof container they mean a box that can withstand fire - not a fireproof box that "contains" any fire.

At the end of the day id probably spend £30-40 on a safe with 2 big bolts on front and that has good heat resistance. I would also place it somewhere that will block all the holes in the back safely (i.e. a brick wall) - nothing that will catch fire

If you need to take a further step circulate it with CO2

Nice. but I have never used any box, I just charge my lipos on the bench next to my PC. I have not had any issues. I do not charge them unattented.

-= I know there is Money in RC helicopters. I put it there=-

Good I wish more people took the precaution when charging lipo's.

I have seen smart, educated, informed and uninformed modelers charge their batteries with the wrong chemistry or wrong number of cells and damage the battery under charge.

It’s good to see someone come up with a good solution.

I keep all my batteries and charge them in a steel box. Better safe than sorry. At least I can leave them unattented for short periods without paranoia setting in. I've never had a problem with Lipos, but a few years back, had a nicad pack burst into flames on trickle charge. Luckily I was sitting right next to it at the time.

Batteries
Hi, I'm not an electric guy nor chemist one, and reading this post makes me wonder if this blowing/burning thing could happen with Ni-Mh or Ni-Cad batteries.

Any heard stories or any ideas about this?

A few years ago I had a NiCad racing pack on trickle charge right next to me on my bench. Suddenly flames shot out of it and I nearly crapped myself. This is the only time it's ever happened to me, but once is enough.

I see the key, do you lock the box when you charge

I purchased a "battery bunker" made just for LiPos.

OK, here's my cheap alternative.

Set your charger on your kitchen sink, and place your Li-Po battery in the oven. By definition they are fireproof............
