This document introduces the features, usage and precautions of the FrSky battery voltage sensor.
The FrSky Battery Voltage Sensor is an optional accessory designed for use with FrSky Dual Way Telemetry Systems. It allows users to monitor battery voltage by connecting to the telemetry receiver's analog input pins (AD1/AD2).
The sensor supports three voltage ranges depending on the battery configuration: 0V~6.6V for up to 1S LiPo, 0V~13.2V for up to 3S LiPo, and 0V~19.8V for up to 5S LiPo. Installation requires connecting the red wire to the battery voltage and the black wire to GND, with the 2-wire black plug connecting to the receiver.
| Voltage Range (1S) | 0V~6.6V |
|---|---|
| Voltage Range (3S) | 0V~13.2V |
| Voltage Range (5S) | 0V~19.8V |
| Compatible Receiver | FrSky Two Way Telemetry Receiver (D8R) |
The sensor supports a voltage range from 0V to 13.2V for up to 3S lipo batteries.
You must connect the RED wire to the battery voltage.
