1.2.6 Telemetry of Model Battery and Receiver Voltage
When done binding with R8FG, R7FG or R8F receiver, besides the telemetry of RSSI, receiver voltage,
model battery voltage (maximum up to 8S lithium battery, 33.6V) can also be returned in real time. Users can
personalize the warning value of low model battery voltage depending on the actual needs.
Press EXIT and ENTER simultaneously to enter MENU=>press Inc(+) to highlight “19. ALARM =>Press
ENTER to set the model battery voltage warning value.
Normally we set the warning value with the single cell voltage as 3.7V. For example, if it is 3S lithium battery
used in the model car, the warning value should be set as
（
3.7V*3S=
）
11.1V.
Model battery voltage return can be easily achieved by connecting the male end of the battery wire to ESC
while the female end to the battery and the wire with a JST head connects TELEMETRY (+-) of
R8FG/R7FG/R8F as below picture shown. No extra module is needed.
Once connect with success, the returned model voltage will be displayed on the interface of returned flight
information.
Note
1. Battery connected to TELEMETRY port is only for 2S-8S battery voltage telemetry. The TELEMETRY
port cannot be used to power the receiver.
2. Make sure the polarity of the battery is not reversed. Otherwise reverse insertion will cause abnormal
voltage display of telemetry.
Note: The telemetry function of model battery voltage can only be realized with R8FG/R7FG/R8F receiver.
