I used to use an ammo can but any more I just keep my charger and power supply on a metal cookie pan, and charge on that. The worst it can do is stink up my house, nothing flammable is near it. I may start using my wood stove, but can't do it this time of year, the wood stove is kind of being used. Heck I tried to experience a lipo fire by "retiring" an old pack, but shorting it and puncturing it did nothing at all. I was very disappointed.

As far as the charger, I would rather not mention the make other than to say it was a name brand charger. It was not a cheapo, no-name import. I've had the charger for 1 1/2 to 2 years and it has always worked fine until recently.
I think it would be good to tell us what charger it is because there may be others (myself included) that have the same charger and it would be good to know so we can make sure ours are ok. People are not asking so that they can slam the manfactuer but to check theirs out. I sure know I would like to know to be preventive rather than have an issue later and find out that it was the same unit you used and it could have been avoided.

What really concerns me is that you were only charging at 1C AND using a balancer.

I hope you rethink and let us know what model it was

Lipos

First, you can purchase or make yourself balancer lead extensions that get your packs away from your charger and into some safe container while charging.

Second, there's a guy that flies electric planks in my area that comes to the field, opens the hood of his car, and proceeds to charge his lipos with his charger connected to his car battery. He just lays everything out on his fender and intake manifold. Since I noticed him, I never park anywhere near his car. The thing's a real junker, so I guess he's not worried about the loss. I haven't the courage to lecture him on the dangers, so perhaps someday I pust a picture of his fireball...

where are those pictures with the burning van? print those up and leave them under his lipos next time he's at the field.

Dave,

I use the ammo can thing for both charging in, and storing mine in (two seperate cans). I have to put my charger in the can (I use 1500 round 7.62mm can), but honestly it's a small price to pay if she lights off. Think the big can that I have ran me 15 bucks at the surplus store. I picked that size and caliber due to the metal thickness of it. Sorry to see your Rhinos light up. Did your charger have an overcurrent safety on her? Just curious.

I used to be normal, but then I started flying heli's....

Hi JC,
I now charge all my lipos in a lipo sack, and keep them away from things that burn. I also bought several ammo cans (two sizes) and store all my batteries in them. I may cut a hole in one of the larger ones to use as a charging box. The other thing I do (saw it on the Utahflyers sight) is put a zip lock bag filled with sand over the charging battery. If the battery overheats and starts to burn, the plastic bag melts and dumps sand on the fire.

I don't know if my charger had an over-current safety circuit. I believe it went over-voltage. This was the error I had experienced several times before the fire. The company made good on the bad charger, and sent me a new one. Works fine, I'm just much more cautious when charging LiPos.

I do not remove my packs

from my machine...and to my knowledge, there are no documented fires due
to failure using the two high end chargers, (the only ones I use).
They have extensive protection circuitry to prevent this.
They are german, and from companies with extraordinary product documentation and reputation. Any solid state gear can fail, but what is great about these is the internal detecting circuitry for fail safe and shutdown sequencing for any out of limit parameter.

Many of the cheapy units do not have extensive protection circuitry..
Walmart style cost cutting.
Also, many of the so called experts on this very forum have abused battery packs, and then are "shocked" when their "bombs" go off...

If I had to remove and armor my units, I would quit the hobby. I love
the power density of lipos, and cannot wait for higher ones, but
there are hacks on this forum that can break an anvil. Caveat emptor.

If you do not understand Ohm's law, and a lot of guys here do not,
then one cannot be too careful...no one should be using these without
a thorough understanding of lipo chemistry and theory. This information is readily available for free.

Yes you are right, German equipment never fails. Good luck to you.

Never said never...

if you read the post, you will see why it is quite safe with the
caveats mentioned.

But you would have had to read it...

Yes, I read your reply. However, I prefer not to have to rely on safety circuits - they also fail. Simply charging LiPos in a safe environment prevents disaster from equipment and human failure. I was careless and I got lucky. I won't do that again.

When charging and storing I put my lipos in a old boiling pot thats about a foot or so high and a foot and a half diamter. I know for sure it will hold up to the heat and direct any flames upwards, I keep it at least 15 feet from anything that can catch on fire and I have a fire extinguisher just in case. I'm thinking about getting a lipo sack to put them into as well as a extra measure of safety. It's really not a hassle, I charge them right next to me when I'm watching TV, on the computer, or studying, so if it starts puffing or anything I can catch it in time.
