That's true -- 25C on a 5400mah battery IS better than 40C on a 2200mah battery -- but I personally wouldn't recommend either of those batteries with a Mamba Monster.
All of these things add up to make it hard on the ESC, and especially on the capacitors.. The capacitors are there to keep the voltage at the ESC as smooth as possible. If you use connectors that are too small, and batteries that are too low C rating, the results are damaged capacitors.
Thanx!

ok i'll try to change the capacitors and see if it works and get some new battery's thanks for your help
