1/8 scale battery size Question
I have an 1/8 scale truggy and my ESC can handle up to a 4cell-14.8v lipo. What is the difference in using 5000mah and a 3000mah. is there a power difference??

Battery choice should be determined by the motor
Your motor will have a continuous current rating
Example
100 Amp motor
Pack 1 - 5000mah 20c pack = capable of delivering 100 amps
Pack 2 - 5000mah 40c pack = capable of delivering 200 amps
Pack 2 is a better choice as 1 is close to its limit
Generally speaking higher mah = longer runtime as long as the packs can keep up with the motor
Cheers

If both 5000 and 3000mah have the same C rating, there shouldn't be a power difference. The 5000 will provide longer run time.
Its not really that simple though as the motor is what drives the amp demand in a setup.
