Fan weight: 246 grams
Rated voltage: DC21.6V
Rated Power: 150W
Current: 7.9A

The 545 motor is a compensation brush motor, longer life than normal carbon brush motor.
Motor is dual ball bearing.
Voltage Range: 12V-24V.
Test data:
18V no-load current: 6.2A
18.5V no-load current: 6.5A


and the voltage can be higher or lower, and its power is directly determined by the voltage.
However, since these are high-power and dense motors, the voltage cannot exceed too much.



This type of fan is generally powered by high-power lithium batteries,
and it is best not to use a regulated switching power supply because its starting current exceeds 30A.
Moreover, due to the impeller of the fan, it is necessary to determine the direction of rotation.
Therefore, please note that the terminal with a red dot is connected to the positive pole,
while the terminal without a red dot is connected to the negative pole.
