FrSky ADVANCE (ADV) series has comprehensive sensor types and enhanced the performance and capability of the original sensor line, all ADV sensors fully support FBUS protocol and they are also S.Port compatible. With the FBUS protocol, the ADV sensors can be seamlessly paired with the FBUS capable receiver and further simplifying the builds setup.
The FLVS ADV voltage sensor can measure the voltage range for 2S to 8S Li-Po batteries.
This is an obvious choice for accurate measurement of Li-Po batteries with big capacity.

Why We Recommend This
The FLVS ADV is the simplest way to add pack voltage monitoring to any FBUS build — covering 2S through 8S LiPo packs with per-cell voltage display on your transmitter. A low-cost addition that prevents over-discharge events on expensive battery packs. FPV Builds RC provides U.S.-based product support, sensor-selection assistance, and setup guidance for FrSky products purchased through our store.
Frequently Asked Questions:
What is the FrSky FLVS ADV voltage sensor used for?
The FLVS ADV is a dedicated battery voltage sensor that streams pack voltage to your FrSky transmitter as live telemetry via FBUS or S.Port. It is used on aircraft where a current sensor is not installed or is not practical — such as gas-powered models, turbine jets, or builds where you only need voltage monitoring without current measurement. It lets you set low-voltage alerts in ETHOS to protect your LiPo and avoid deep discharge.
What voltage range does the FLVS ADV cover?
The FLVS ADV supports voltage monitoring for packs up to 35V, covering 2S through approximately 8S LiPo configurations. For higher voltage packs or applications requiring both current and voltage measurement, consider the FAS100 ADV or FAS150 ADV current sensors instead, which also measure voltage up to 14S or 60V respectively.

Which FrSky receivers is the FLVS ADV compatible with?
The FLVS ADV connects via FBUS or S.Port and is compatible with all FrSky TD Tandem, TW Twin, and Archer Plus receiver families. FBUS is the preferred connection for current receiver builds. Browse compatible receivers at https://www.fpvbuildsrc.com/frsky-receivers.
How do I wire the FLVS ADV into my aircraft?
Connect the FLVS ADV in parallel across your battery pack — it only taps voltage, not current, so it does not need to be wired in series with the main power lead. Run the FBUS or S.Port signal wire to your receiver's corresponding port. Refer to the FrSky FLVS ADV wiring diagram for the exact connector and polarity details.
How does voltage telemetry display in ETHOS on my transmitter?
When connected via FBUS to a Tandem X18 or X20 series transmitter running ETHOS, battery voltage appears as a live telemetry field. You can add it to your transmitter home screen and configure a low-voltage audio alert — typically set at 3.5V per cell — to warn you before your pack enters the damage zone during flight.
Do I need the FLVS ADV if I already have a FAS current sensor?
No. FrSky FAS series current sensors (FAS40, FAS100, FAS150) also measure battery voltage in addition to current. The FLVS ADV is the right choice when you want voltage-only monitoring without the current measurement overhead, typically on lighter gas-powered builds or models where a dedicated current sensor isn't warranted.
Does FPV Builds RC offer setup support for the FLVS ADV?
Yes. FPV Builds RC is a U.S.-based FrSky dealer and can assist with wiring and ETHOS voltage alert configuration. Browse the full FrSky sensor lineup at https://www.fpvbuildsrc.com/frsky-sensors.
