Power

The recommended power source is a 3s1p Li-Poly battery. 

Power input is wide:
7.5-13.0VDC is the effective voltage range for this transmitter.
<7.5VDC the transmitter does not operate.
7.5-10.0VDC the transmitter will operate with reduced range.
11.0-13.0VDC is optimal for the maximum transmitting distance. 

The transmitter heats up relative to the operating voltage. It is normal for the transmitter to heat up 50 degrees Celsius when being powered from a 12VDC source. For prolonged life it is recommended to use a heat sink or place the transmitter in airflow.
