C ratings ?????

If the factory recommended battery for my plane is a 14.8v 2200mah 25c and I use a 14.8v 2200mah 45c battery. Will the difference in C ratings cause any problems ?
I'm using a 50amp esc, a 650kv 12pole motor, with a 13x6 prop.

With the 45C battery, you will probably have a higher loaded voltage. Normally, this will not cause any problems. However, if your power system is already being pushed, the extra loaded voltage and increased power available can result in component overloading. It is a good idea to comfortably overrate power system components to accommodate intermittent power surges.

If you are concerned about over taxing your system with the higher C battery get a watt meter and see for yourself if it causes a problem.

I do not think the additional C rating will be a problem.
