Default Ep 4200 Has blown up in my face

Just been sitting in my out house tinkering with my car when a EP 4200 has just went bang 2 feet away from me, the cells were on top of my plastic tool box NOTHING and i can't stress enough NOTHING was anywhere near them, They were not on charge and were not used since last week, Im lucky the cells did not fire in my direction, Two exploded and have melted my tool box top and set fire to my pit towel.

That's a bit more to worry about, leaving the cells in my room when i go out and they could still blow up and fire. Good to hear you wern't hurt, Is there anything can be done for safety??
Did you used to charge at the suggested rates etc?
Cheers

Yes mate always charged at 4.5 amps never re peaked as always charged on the day i race, they were taking off the charger at 4200 and always had around 2000 in them when stored discharged equalised left to cool down and charged about 2 to 3 hours later

Not on charge or discharge, not short circuited and not used for a week, i cant understand that at all. What state of charge were they in? were they in direct sunlight? (i mean sun directly on them).

Mine are always kept in their box to, but when I had a set of IBs go bang at the end of 06, they just blew the box to bits!! only sitting 2 feet or so away at the time, thought at first that someone had come in the back door and shot my dog, then noticed my Cyclone TC which had been sitting on the cell box was 4 feet in the air!

Took a long time for my wife to let me keep them in the house after that.

Will NEVER buy IBs again.

So, even thought the brca have decided on the legal cells for 2008, can they allow Lipo's on safety grounds?

Glad you weren't hurt dude.
