My son wanted to plug the battery while i was looking away, he inversed + and - as banana plugs are used on my esc...

Results: undesired sound, big spark, little smoke, itchy fingers and a car that don't run.
Turning on the switch steering and both fans running plus a nice double blinky ESC (twice legal for GT2 !!)
Seriously, I have the LRP Flow Esc and I have blue and green leds flashing showing that it would be a battery voltage or cutoff issue. Changed the battery for other one and same results.

I was suggested to remove capacitor but now I have 3 lights blinking...

Is it the end of my Esc's life ?
