Battery BOOM! box

[Sheriff420]

There sure is a lot of "ha ha look at that guy, he's so paranoid" going around in this thread.
I saw where these batteries can fail, then vent, then shoot a fireball out of the end so I took an hour out of a day off and used some scrap metal that was in the shed to make a box to charge my batteries in when I charge them unattended. I like doing little projects like that so I enjoyed making it. I used metal vs. a lipo bag because it is what was available to me at the time and I tend to work with what I have. I don't see it as being any more paranoid than anyone using a lipo bag, a dutch oven or a granite counter top in a garage. All of my outlets are in flammable locations so this isn't a bad idea to charge in a box that will contain the flame if a battery does fail.
I don't think I'm going to get in a wreck while I'm on the road but I wear a seat belt when I'm in a car.
I don't expect to hit my leg with my chainsaw when I'm cutting trees but I still wear cut-proof chaps.
I don't expect lightning to hit the house but my electronics are on surge protectors.
I don't expect to run over a nail when I'm on the road but I keep a plug kit and pump in my truck.
I don't expect to have the house broken into but I keep my guns loaded and the dogs well fed.
I don't expect to hit a 300 yard drive on the golf course but when the group in front of me is within 300 yards I wait for them to move on because I have hit one that far.
I could go on for days with safety precautions that are taken for every "what if" in life but I think I've made my point.

I don't think it is over the top at all. Personal safety for yourself and family is very important.

If I wasn't so lazy and complacent I would be making one too.

Here is the prototype of the ecig safety mask made of kevlar.

Oh Good, another use for that.

Hopefully none of my batteries blow but if they do, I'll have severely reduced damage or maybe no damage due to my explosive containment unit.
The tray has clearance around the sides and top for ventilation and is locked in place securely while the batteries are charging.
The groves in the eGo charger fit perfectly in the slots on the front so it holds the 650mah batterys far enough away from the back of the tray to allow the end caps to blow out if there is a failure.

It will even work with the 900mah batteries

Wow! Wicked!

I like it, but am curious, have you tried exploding a battery intentionally in it to see what the outcome will be? Vented ammo cans are common box used also, however, I believe I saw a test done with a 50cal can that was vented and it exploded.

I loaded it up with sparklers and bottle rockets. Some sparks did come out the end a few inches and that's why I redesigned it and have thought of redesigning the redesigned drawing. Then again, an ammo can would be a pretty good one, with bigger vents of course. I might just go the ammo can route and get a 2' or 3' extension cord so the whole thing can fit in the can. I'm gonna need something bigger anyway since I'm about to get an e-power 14650.
