1.2.5 Transmitter Battery Charging
The working voltage of T8FB is 4.8V-18V, and the low voltage alarm is self-adaptive. For
example: if you are using a 2S lithium battery to power T8FB, T8FB will send out a beep sound
alarm when the battery voltage reaches 7.3V automatically, with no separate settings.
Power supply battery selection forT8FB: You can use the standard battery box to with 4 pieces
1.5V NiMH batteries for power supply, or use lithium batteries (2S/3S/4S) to supply power.
Note: When inserting the battery, please make sure the positive and negative poles are inserted
correctly. Since the T8FB has anti-reverse insertion function, if the positive and negative poles are
inserted reversely, T8FB will not be powered on, and the T8FB will not be damaged. So please
insert the battery correctly when the positive and negative poles are reversed.
