Losi 4s hard cased lipo died.
 

Got about 10 runs out of it and it just died in the middle of a 5 minute qualifier. No voltage, nothing. Battery was never stressed, never got hot, charged at 1C and never discharged below 3v per cell. Called Losi and they said, sorry no warranty on Lipos.
What a waste of $220.

Send it to me and I will check it for you... Check the link in my sig and pm me if you want me to give it a try...

sounds like a bad wire connection or a broken tab, had the same problem- linc is the man to fix it :)

I'll have to give linc a try. There is definitely a loose connection.
You can wiggle the leads around and the voltage flashes on and off.
