標題: Li-po Battery Question
Is the 'Power' of the battery only determine by the 'C' value and independent of the 'mah' value of the battery?

For example, 25c 3600mah battery should has same Power as 25c 5000mah battery. The only different is that the 25c 5000mah battery has a higher storage capacity and can play for longer time.

Thank in advance!

mAH 是容量. c 是 放電量. 自己計下數就明了. . . ..

Is the output Power = C x mAH ?
Then both factors will affect the power of the battery.

C = Max discharge rate
mAh = Capacity

Max Amp = C x mAh / 1000
eg: 5000mAh @ 40C => 40 x 5000 / 1000 = 40 x 5 = 200A

Power = Current x Voltage
so Power = 200A x 7.4v = 1480Watts
(please note that will be a voltage drop at very high current, so 7.4V is just an assumption.)

so mAh and C will affect power output.

Thanks! Hardmankam c-hing,

Very very clear and detail explanation.
