Overview
The FrSky ADV FLVS is a voltage sensor for Li-Po battery monitoring in FrSky telemetry systems. The FrSky ADVANCE (ADV) sensor series fully supports the FBUS protocol and is also S.Port compatible, helping simplify wiring and setup with FBUS-capable receivers. The FLVS ADV measures multi-cell Li-Po voltage and can show cell voltages on an onboard OLED display (screen version).
Key Features
- ADV series sensor with FBUS support and S.Port compatibility
- Li-Po voltage measurement range: 2S to 8S (cell taps labeled 1S to 8S on the sensor)
- OLED display version supports on-device voltage readout, including individual cell voltages
- Battery port connection for the LiPo battery
- Smart Port connection for S.Port on other FrSky sensors/receivers
- Status LED indicator
- GND marking on the module
