Had the experience of a intellect single cell explode over the weekend.

Sharing a pitt table with another competitor in a room with another 20+ people, the cell self exploded on our table while working on cars.No one was injured.

We had just returned from our heat and started working on the cars when we noticed a battery pack (that had been charged and placed in a non conductive battery box)starting to smoke and sizzle (something that i have seen before, but only on charge or in a equal' tray) Picking up the pack it fell apart from heat. Thinking that was the end of it, some 3-4 minutes later a single cell let off a bomb like explosion as load as a shotgun.

From this experience if anyone witnesses this sort of over-heating activity of a battery pack i would recommend you to place the pack (or cells) into a strong case or container such as a transmitter case and then remove them from the pitt area.

The pack had only been chagred at 6 volts and with a heat sensor, the pack must have shorted out some way?
