E-flite Power 32 Brushless Outrunner Motor, 770Kv - Manual (Page 2)

Average Voltage (depending on cell count) x Continuous Current = Continuous Input Watts
Average Voltage (depending on cell count) x Max Burst Current = Burst Input Watts
HINT: The typical average voltage under load of a Ni-Cd/Ni-MH cell is 1.0 volt. The typical average voltage under load of a Li-Po cell is 3.3 volts. This means
the typical average voltage under load of a 10 cell Ni-MH pack is approximately 10 volts and a 3 cell Li-Po pack is approximately 9.9 volts. Due to variations
in the performance of a given battery, the average voltage under load may be higher or lower. These however are good starting points for initial calculations.
Model: 25-size aerobatic/3D airplane
Estimated Flying Weight w/Battery: 4.1 lbs
Total Input Watts Required for Desired Performance: 533 (minimum)
Motor: Power 32
Max Continuous Current: 42A*
Max Burst Current: 60A*
Cells (Li-Po): 3
3 Cells, Continuous Power Capability: 9.9 Volts (3 x 3.3) x 42 Amps = 416 Watts
3 Cells, Max Burst Power Capability: 9.9 Volts (3 x 3.3) x 60 Amps = 594 Watts
Per this example, the Power 32 motor (when using a 3S Li-Po pack) can deliver up to 594 watts of input power, readily capable of powering a 25-size
aerobatic/3D airplane with the desired level of performance (requiring 533 watts minimum). You must however be sure that the battery chosen for power can
adequately supply the current requirements of the system for the required performance.
Battery Choices:
We recommend Thunder Power Li-Po batteries for the best performance and lowest weight (in some cases Ni-MH 1800-2200mAh high-discharge packs also
make good alternatives at the expense of weight and lower capacity). Some examples of the packs we recommend for use with the Power 32 motor can be
found below:
