LOL, the liability insurance to sell something like this is probably the reason it isn't being sold. I just need something bulletproof to store and charge these things. The safes are a joke. You'd think I would have learned when it happened a few years ago, don't want history to repeat itself.
I think water is the ticket. I am going to do some experimenting with old packs. I'll over charge one and dump it in a bucket of water to see what it does :-) Water is much cheaper than the fire extinguisher too.
