mAh size
 

I have 14.8v 25c 5000 mAh batteries. Can I use them in an Airplane I just purchased that requires 14.8v 25c 2600 mAh batteries
or is the 5000 too much and cause damage?

The voltage is the same so it shouldnt cause any damage but you may have a hard time getting them to fit or to get the plane to balance depending on how much space you have.

Thank you for your help. The Battery will fit, however, I may have to add weight for balance. I was just afraid it would do damage to the ESC or motor.
I'm sorry for the delay in response to your answer. I had hand surgery on my left hand Tuesday, so my hand is still sore.

No worries. Nope. Marching your voltages is the big thing. Mah just determines how long long it's gonna last...it still outputs the same power. Hope you have a quick recovery!
