Regarding that fire, this was recently posted by Olly on the yahoo groups NEDRA forum:
The car was stationary, awaiting a tow back to the pits after a run.
We believe the damage may of occurred during the run but took a few minutes to become apparent.
Olly also posted the original news of this event in this manner:
We need to discuss safety with lithium batteries, after our first big fire.
Three fire crews could not get the fire under control.
Black Current 3 is toast! :-(
More info to come....
I hope in a short time we will find out all of the details of this very serious flightpower battery fire.
