Well that's certainly a wakeup call! Glad you caught it before it spread. What did it take to get it put out?

For sure. Im going to have to find a way to store about 50 batteries!
A while back I had grass fire by the house and had to rush to put a bunch of hoses together. That made me have a long hose already ready in the event of another fire happening. Ran to the garage and grabbed my 3M mask I wear for spraying paint, then just ran in with the hose quick to put it out. Cut the power at the box and ran out. Put a fan blowing out and watched it all night to make sure nothing kicked back up. Learn something new with each disaster in my life :D |

I understand that they go hand in hand, but you think it was the charger, not the battery?

I don't trust the batteries. I have considered making a tiny shed with an AC unit on it that I charge and store them in.

Man that sucks OP. I charge mine on a metal wire rack and store batteries in ammo cans with part of the seal removed. Even still, the thought of what happened to you is always on my mind.

Hard to say what happened.
I want to say the batteries wouldn't blow without being over charged by the charger. That said, one time we got done running our xmaxx's and I got lazy and forgot to hook up 2 of the 4 batteries for storage charge. Came back the next day and they were all swollen up and I threw them out. Thinking its dangerous all the way around! Makes me think about how much lithium batteries are under a tesla |

A neighbor had his garage catch fire. He was buying china rc things on ebay and flipping them on Craigs. He lost two frame off restored classic cars (GTO and a Vette), a tractor, and three cars in the driveway. Fire dept arrived just as the flames got through the firewall to the main house and did damage. His house had to be gutted and he was displaced for over a year. I was there when they pulled the cars out of the garage, and they were a total loss. It was 2AM and the smoke alarms saved their lives. I was awakened around 3AM when they were refilling the apparatus with water right outside my house. I heard the diesel engine and looked out the window to see blue and red lights. I thought my house was on fire.
He was not happy with GEICO shenanigans. Battery tool lovers that keep their batts on the chargers are also at risk. There have been several CPSC recalls on various models for fire hazard. |

I've heard of people repurposing a grill as a charging station. Like an old gas grill. They can handle the heat and are open to allow cords and things to plug in.
I may go that route, but I'm not sure how the heat/cold of the garage would hurt the batteries. Sorry if I missed it, but what batteries were they? |

When I flew CP helis, the battery charging always produced a little anxiety. Especially the 550-700 size birds with high discharge, high capacity lipos.
So. I charged my batteries in a fireproof bag, inside a large ammo can lined with fire-proof brick. I'd close the lid, but not latch it. |

I've seen plenty of Lipo battery fires online and it seems like trying to contain completely and let the can vent pressure through deformation is the best way? Just curious what your thought process is. I'm about to lock up every lithium battery I have in some sort of burn box. |

How much insulation would triple layer sheetrock buy us?
It would still need to vent outside. |

I had a friend have one blow up when I was a kid. Luckily they weren't in the room.

There are a ton of valid places to cut corners. Things that have a tendency to explode or otherwise cause glorious fires is not one of those areas. I buy expensive Spektrum batteries.

Fellow RC nerd. Damn man, glad you caught it! I always worry about this kind of thing happening.

View Quote All the expensive lipo charge boxes have vents, so I just went with that. I only removed the front piece of the fat .50 can seals so it still latches tight but has a small vent. I'm no expert but I don't like the idea of having a bunch of lipos in a small, airtight container. And not all China batteries are created equal. Obsessed is correct in saying that. I have some 4S2P packs that were $180 each for my 8s speed run cars. The IR for all cells is around 1 ohm or less. These batteries have powered runs that have maxed out at over 650 amps. No way in hell an Amazon battery will even come close to doing that without the voltage sagging down to unsafe levels. |

im not into batteries much sorry for dumb question.
ive seen this with batteries alot lately. im wondering if my batteries are safe to store in house now. ive got a saw can full of lithium energizer aa and cr123a surefire batteries and the only rechargable is a mega bright cloud defense owl. should i be concerned at all? ive left the big lithium owl batteries charging alone before. its any lithium rechargable and not the non rechargable lithium thats starting fires correct? |

View Quote Batteries don’t self combust. If they did, every Home Depot and Lowes would have burned down long ago. The problem is in the cheap battery management systems (BMS) of the chargers. Large batteries have the BMS built in, which makes it seem the battery itself is to blame, but it is the BMS. The BMS manages over-voltage, over-current, over-temperature, and charging profile. When Wang Hung Lo designs cheap electronics with brainless algorithms, you get fires. |

If all studies done, it's pretty conclusive that these are all caused by the same thing. The battery internally shorts for whatever reason...likely crap internal wiring or on board circuitry, this causes it to overheat. Overheating leads to off gassing. Off gassing of flammable gasses lead to the explosion that is often reported, which leads to bigger fire, which leads to more off gassing, etc. Lithium batteries have their own oxygen and so can self sustain, and thermal runaway keeps the process going which is why they are notoriously difficult to put out. |

Without you stating anything factual, would you feel better if I said "extremely rare"? And probably so rare that the incidence we do see is not largely attributable to battery physics but is instead attributable to poor battery management. Now you may expound on your knowledge of BMS and why bazillions of AAA, AA, and 9V lithium batteries are not catching fire on the shelf in department stores. Why Do Batteries Sometimes Catch Fire and Explode? |

I charge either in a cold woodburner stove. Or outside on cement away from any structure, and shaded.
I haven’t don’t much flying lately when it wasn’t nice so using either was not a problem. Some people will set some cinder blocks outside and put the batteries in the holes while charging There used to be some ceramic pots that were sold for storing batteries while charging - they had vent holes too so if a battery did start to combust it wouldn’t turn into more of a bomb than it already was. |
