Fault with speed passion esc
 

Hi there

I'm running the reventon pro esc and have done for two years without any major issues. Yesterday it ran fine thoughout the rounds at Worksop and in finals as I went to drive the car off the speedo shut down completely as if lost all power

Wouldn't power back on, so I assumed a cell had failed. Changed the saddle pack and it powered up. But as soon as I by drove, the same thing happened again. All power gone

Checked batteries and were all still fully charged

Any ideas as to what the fix could be?

From memory, all voltage settings etc were disabled or at least turned right down

I've had it once or twice.
First thing i tried was reflashing the firmware.
That worked.
