I think one of the cells may have been bad. The battery is only 2 weeks old and has 3 charges on it. I charged the pack last weekend and it sat for 6 days un touched. I took the pack off the shelf and as I was placing it in the buggy it swelled, fizzed and blew out a garage full of smoke.
It would have popped much sooner if it was overcharged and it was not punctured. If you look at the pictures the velcro is on the bottom to keep it from moving, and the cell that blew was on the top. It happend while I was putting it into the buggy and it was not plugged in to anything.
I mentioned this to Austin, over at Max Amps and emailed him the same pictures. He offered to ship me a new one immediately at no charge. So I cant really complain, other than it sucks that it happened and that I had to replace a couple of damaged things.

some of the paranoid airplane guys have rigged up charging stations with the lipo in the hole of a cinder block on it's side with a bag of sand hanging over it.
the thought is if the lipo goes up, the fire/heat melts the bag, and the sand extinguishes the fire.
little overboard if you ask me.

I've seen a lot of nimh fires/explosions and I have yet to see a lipo flame or pop in the whole time that I've been in this hobby. Personally, I've had a mini-t nimh pack blow up on the charger and just this past weekend had a brand new Trinity EP4600 nimh pack catch fire and melt the chassis of my XXX-t on its very first run:
I've ordered a lipo pack for the XXX-T...who knows what I'll burn up now

Just want to ask if you noticed that text on almost every part of your car - graphite and what graphite is - electric conductor - try to isolate your chassis with tape first - i did it all time with my XXXBK2 to be sure. I have heard about melted XX4 graphite chassis on 12V car batery - it just did short circuit.

Don't hold it in bro. You're amoung friends. You can say what you realy think!!!
BTW-I agree. People that do stupid things, then sue the manufacterer for damages/injuries caused by dumb$%!& opperator error should be placed in a burlap sack with rabid rats and tossed in an open sewer!!!!!!
