Looks to me like it needs some larger capacitors. ESCs with small capacitors quite often have problems with longer power leads causing ripple voltages that end of destroying the ESC. I am not saying this is a fact with this ESC, but this has been my experience with other ESCs.

A bit more specific: not enough input capacitors/capacitance and/or long battery wires cause voltage spikes higher than battery voltage:
Too long battery wires kill ESC over time: precautions solutions workarounds - RCG
