    Excellent video Jb,

    That is enough to put a lot of people off using Lipo batteries.

    Having said that if proper care is taken you will not have the disastrous consequences that you have seen in the video.

    Even more reason to use the words " Stay Safe"

    If it looks right it probably is.

    A good vid on using ammo boxes and Lipo sacks. They are mainly using large batteries for these tests and the one with the ammo box with lid ajar (assuming it's a demo of what can happen with a tin full of stored batteries as I mentioned previously ) is easily a house gone situation!

    Thanks JB. Actually cut a chunk out of the seal to let the leads through.
    The remainder of the seal keeps the lid from rattling

    Re - Hopefully you will never have to use it in anger although better safe than sorry.

    Correct Martin, as I mentioned, I've never trusted LiPo sacks as I have never seen a 100% successful suppression example. Fine for outside but not for inside (my opinion) unless you are doing it in your fireplace๐Ÿ˜. I always balance charge my batteries at 1.5A ,-takes ages but they never move in temperature. There is also a temp sensor you can use on many chargers, and with mine, if I'm charging a bigger battery, I set it low to 30deg C and it will cut the charger off immediately and start beeping if it ever gets to that. I don't think many people bother to use this feature, even if the charger is capable, but it's a good extra pre-emptive safety measure. It can actually stop a potential problem.

    You really don't want a battery going off in your house no matter how it's contained, as the smoke would make your house almost unlivable for months. I've let lots of them burn in the back yard (giving them a good 'forking') and boy do they smell bad and put out some serious smoke! (even a small 2s)

    Re I use an old steel ammunition box. Just trimmed the rubber lid seal

    Hi Rowan -Re the tool box vid below, It's a good idea to remove the seal to stop pressurisation, as the guy says, รฟou don't want to build a pipe bomb!๐Ÿ˜ฎ That's why I bored a hole in mine (has no seal but just to be sure)

    Hi MB, I actually have an ammo box (ex my fathers from his Air Force days in the 40s) but I'm using it for tools at the moment, hence the new box ($15) We were having a discussion about steel boxes at an RC plane club, and a guy said, "I keep all my LiPos in an ammo box for safety". He opened it up and inside was a literal Bomb of LiPos all stacked in there. 6s, 5s, 4s ,-the whole range and full to the top. Everyone said (almost as one) "what if one goes off in there"!!! Holy cr-p!!

    Your Idea's a much better one but I think more than one is still risky as the bags obviously aren't foolproof. It would be interesting to test that out with some old lipos to see if nearby LiPos were affected at all. You do need adequate vent holes with a flame suppressor or else you are risking blowing the box up if it's clamped shut. Here's a vid of a tool box test with sand bags, -worked pretty well!. Unfortunately there's no getting away from the smoke!

    Also one with an ammo tin which also worked well ( I saw a test on another vid, and the guy said to leave the seal out of the box for venting (the guy in this vid mentions they have done this also)

    I think that any precautions are a good idea. I have several LiPo batteries and also keep them at storage charge in a few ammunition boxes. Good quality solid boxes can be bought for around ยฃ10 on ebay. I keep each battery in a fire proof bag and then in the box. Belt and braces.๐Ÿ˜Š

    I use an old steel ammunition box. Just trimmed the rubber lid seal so could get the leads in and then clamp the it down with the lock.
    These boxes are quite inexpensive and very robust.
    Seems to work OK, but have never experienced any LI-PO malfunction in the several years have used them

    I like it Jb,

    Hopefully you will never have to use it in anger although better safe than sorry.

    I would imagine the guys that are new to this hobby are beginning to wonder what they have let themselves in for after seeing this LOL!!
