 Description / LiPo    3s (11.1v)    4s (14.8v) 
 Thrust: 900 g  1460 g
 Current: 33 A 52 A
 Power: 416 W 874 W
 Recommended ECS:  40 A   65 A
 Recommended Battery:     2200mAh 35c   2600mAh 35c

The controller should be chosen 20% over rated due to the long lasting load.
LV = low voltage controller up to 6s, HV = high voltage controller above 6s.
Battery should be chosen about 15/ - 1/20 of the max current for 4-3 minutes WOT. 30-40 C is appropriate.
Operating the motor outside of the specifications listed above can either damage the motor, battery or esc. It is important that these components are set up properly. Failure to do so can void the warranty. It is strongly encouraged to use a Watt Meter to test the watt and amp performance when setting up a new system. If the output is above the factory recommended specs, then it needs to be adjusted by the esc. The timing and throttle settings on the esc can help to set the appropriate levels.
