FrSky FLVS ADV Voltage Sensor with OLED Display – FBUS/S.Port Compatible Accurate 2S-8S LiPo Battery Voltage Measurement for RC Aircraft and Drones(with Screen)
Quick take
The FrSky FLVS ADV adds measured LiPo pack voltage to your RC aircraft or drone setup, with support for both FBUS and S.Port telemetry paths. It’s designed for 2S to 8S LiPo batteries and includes an OLED display for on-device voltage readouts. The biggest practical caveat is that installation and pairing may require updates in your system before it works smoothly.
Pros and cons
Pros
- FBUS and S.Port compatibility simplifies building telemetry-ready setups.
- Measures 2S to 8S LiPo packs with 0.01V voltage resolution.
- OLED screen provides direct voltage visibility without needing to rely solely on the receiver UI.
- Compact, lightweight design for RC builds.
Cons
- Installation may not be plug-and-play for every setup, and updates can be required before pairing.
- Built for LiPo voltage measurement in the 2S to 8S range, so it will not suit batteries outside that span.
What buyers think
Review evidence for this sensor is limited but consistently positive. Buyers generally describe it as working as intended for voltage telemetry, and they report it is straightforward to install with the help of setup guides. A recurring theme is that firmware or system updates may be needed before the sensor can be used in the aircraft, which can add a step to the first-time setup.
What the FrSky FLVS ADV voltage sensor does
The FLVS ADV is a voltage sensor meant to monitor LiPo pack voltage for RC models and drones. It’s built around FrSky’s ADV sensor line, which supports both FBUS and S.Port protocols, so it can fit into different FrSky telemetry ecosystems depending on what receiver and gear you are running.
Onboard, it includes an OLED display, so you can view voltage directly at the sensor rather than relying entirely on telemetry screens. For voltage precision, it targets 2S to 8S LiPo packs and offers 0.01V display resolution, giving more granularity than basic whole-number voltage readouts.
Key specs that matter for buying
Battery compatibility and measurement range
- Supported packs: 2S to 8S LiPo
- Display resolution: 0.01V
- Measurement accuracy (as listed): 0.05V
Telemetry compatibility
This sensor is designed to work with FrSky ADV sensors using FBUS and also supports S.Port. That matters most if you are trying to make an existing telemetry build more complete, or if you are matching the sensor to the receiver’s available telemetry protocol.
Power draw and operating conditions
- S.Port power consumption: 10mA @ 5V
- Operating temperature range: -20°C to 60°C
Pros and cons for real-world RC builds
Pros
- More precise voltage readouts: 0.01V resolution is useful when you want finer detail than rough approximations.
- OLED display onboard: helpful for quick checking, troubleshooting, or setup verification.
- Protocol flexibility: supporting both FBUS and S.Port can reduce compatibility friction depending on the receiver in your fleet.
- Small footprint: with a compact form factor and low weight, it’s easier to fit into tight airframes.
Cons
- May need updates: buyers mention that updates can be required before installation works properly, so plan time for initial setup.
- Limited to LiPo 2S to 8S: if you run different battery chemistries or pack counts outside that range, you’ll need a different sensor solution.
Who should buy this voltage sensor
- You run RC aircraft or drones with FrSky telemetry and want a voltage sensor that matches FBUS or S.Port setups.
- You want on-sensor voltage visibility via an OLED screen, not only telemetry data in your receiver or flight display.
- You fly with 2S to 8S LiPo packs and care about fine-grained voltage readouts for safer cutoff decisions and better charge management.
Who should avoid it
- If your RC system does not align with FBUS or S.Port telemetry pathways, you may spend extra time troubleshooting compatibility.
- If you need voltage monitoring for different battery types or pack sizes outside 2S to 8S, this unit will not match your use case.
- If you want a guaranteed plug-and-play experience with no possibility of updates or initial pairing steps, this may be less ideal.
Bottom-line verdict
The FrSky FLVS ADV is a strong fit for builders who want accurate LiPo voltage measurement with fine resolution and an OLED display, while keeping telemetry integration flexible through FBUS and S.Port compatibility. The main buy-time caution is setup effort, since updates may be required to get the sensor working correctly in your specific system.
