So, I'm gonna' get a metal ammo can and a lipo charge bag...

[RudyF6]

And here's why.

This is from my Redcat Shredder. 2s, uses 2 in series. Started dying under heavy load like it was hitting lvc. Bought 2 new ones and problem solved.
Forgot the originals were just sitting in a parts box, a plastic tub full of cardboard boxes and surrounded by fuel sources. I did not put that in there like that, it's been probably 2 years. What's weird is both batteries show the same storage charge at 3.7 and the other one is fine.
Did I just get lucky finding this?
What should I do with them?

Google search lipo disposal sites local to your area. There's several located near me that take them for free, regardless of condition.

Also, NEVER leave lipos in a box for years at a time without checking on them. Always store in fire safe bags. You got lucky. Don't push it.

there's also this option. expensive, but so is rebuilding your house after it burns down.

Looks like you just need to let some air out of it. Always better to be safe than sorry, batteries are way cheaper than a new home.

So, is the ammo can not so safe? I would store in that but get a lipo safe bag for charging.
That Bat Safe looks pretty elaborate.

The problem with ammo cans is they aren't vented and pressure could build up and cause an explosion. That can easily be fixed by drilling holes in the can but then fire can escape through the holes.

I'd recommend vented ammo cans with the lipo's inside lipo bags inside the cans. Thats pretty much what amain is trying to sell you for $100.

That makes sense.
I'll be shopping now, maybe you'll see a "What did you buy today" post!

iv been kicking around the idea of getting a lipo bag for every battery and storing them in some kind of metal box (ammo box if they would fit).
how air tight are ammo boxes? would drilling a couple small holes (say 1/8") be enough ventilation?

 

[Mrgoodwrench35]

Depends on the ammo can. I've seen some that had rubber seals and were water tight. Others not so much. A few 1/8 inch holes should be plenty.

Here’s an unbiased series on lipo storage solutions which I think everyone in our hobby should watch:

(This is part 2 of 3. Watch them all.)

I use a fireplace ash can, along with lipo bags. It's large enough to hold batteries and charger.

I like that the bat-safe has a filter. In the lipo fire that a club member just had, the structural damage was limited to one garage wall that unfortunately included his breaker panel, so they were out of their home for a couple of weeks. The soot created a real mess, and cleanup of that is the biggest task, pretty much coated everything in the garage and into every nook and cranny. If the filter could really trap most of that it would be well worth it.

I have had two swollen batteries, one in my laptop that popped the touch pad up, another was a jump starter that I am sure got very hot being stored under the seat in my truck. In neither case did the batteries generate any heat.

Currently using a LiPo bag in a small refrigerator in my garage. Was using double bags and 50 cal vented ammo box, but it gets too warm (over 90F) in the summer in the garage and don't want to keep it in the house for obvious reasons. Might see if I can install a thermoelectric cooler in the bat-safe or equivalent. Again, the filter is a great addition if it has enough capacity.

One thing is I think most of us are storing several batteries together but that will just make for a bigger fire than a single battery so that is another dilemma.

Exactly what I use and they are close to the front door so I can quickly throw them outside if need be.

If you go the ammo can route, make sure it is sitting on something that can withstand high temps, like concrete, cinder blocks, etc., it won't do you much good if the heat melts your carpet or catches wood floor on fire (metal gets hot!).

I think home Depot takes them for a program. Mine near me does it.

Yep, mine are in the basement on the concrete slab.

 

[Mrgoodwrench35]

I put mine in lipo bags and the bags get stored in a big metal toolbox on concrete. My lipos dont sit long without use so I dont worry much about it.

Best get rid of your dog too

Thats halarious.
