I'm really sorry to hear this, man!
Dont you have another lipo pack to use with another controller?

Those lipo's didn't do what they should do in the first place. They should never drop that far in voltage on a 120A peak load. and the controller should have used it's cut-off on 12V.. I really don't get this..

is the entire pack swollen or is it 1 cell?

The pack at full charge is 16 volts, and very little swollen creed is not damaged seriously

Though it should NEVER drop that far.. those cells are not good. I would contact flightpower about it. They should stay above 3V per cell on a 50C load..

Yes rigt

For the quark Rene, What tasks that it has succeeded??

The quark failed with the cut-off?

The quark not work...
Not sound for motor, motor not spin, the led is ok, and the steering servo with internal bec is ok

No the eagle tree registration, is for the first pack, the second discharge i dont use eagle and the quark dead

for the quark not shutting off.. like jhautz said..
there's a place to set the voltage cutoff, and then there's a place to actually ENABLE the cutoff. is it possible that you had set the cutoff, but not actually enabled it?

Sounds logical to me!

mmmm its possible...
boys i open the esc and i see two component smoke...
One resistence and one diode(i suppose), in the zone marked "BEC"

That's what i thought. Try a seperate battery pack or a ubec. perhaps it works.
