I have a plane with about a 5 pound flying weight. It came with a Gunther 2028/07 700 watt 39X41 motor which calls for a 9X5 prop if used with a 5 cell battery or a 10X5 prop with a 4 cell. It also came with a Dymond 23680 70 amp ESC. I need a big battery for weight and balance. I got a 5 cell 30C continuous discharge 4000 mah battery. I'm concerned that this might be too much battery and burn up the ESC. I found a formula for battery amps which for this battery would be 30C X 4amps = 120 amps output max continuous load. I assume a 30C 4000mah 4 cell would also have 120 amps max continuous output.

So the question is, will the 70 amp ESC and 5 cell battery work okay together or do I need to change one or the other? If I need to change, what do I need to go to?
