The FLVS ADV w/o replaces the FrSky MLVSS Mini Voltage Sensor - updates include support for F.Port receivers, wider voltage sensing range, now 2-8S and reverse polarity protection!

For those with smaller, weight critical aircraft, FrSky have released the FLVS ADV LiPo Voltage Sensor without screen. It is designed to measure battery voltage for 2S to 8S Li-Pos which can then be transmitted via the F.Port or Smart Port (S.Port) of telemetry-enabled receivers such as X8R, X6R, X4R, etc to a compatible controllers, such as a Taranis or other OpenTx radios.

By removing the OLED screen from the FLVS sensor and reconfiguring the remaining circuit FrSky has managed to reduce the size and weight of the sensor which is ideal for smaller aircraft models. Otherwise the functionality of the FLVS ADV w/o is identical to that of the FLVS ADV.

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 further simplifying the builds setup. Sensor can be "daisy-chained" together with other FrSky telemetry sensors such as battery voltage, current, RPM, variometer and GPS to provide a complete data package.

Can you advise me if the MLVSS  FLVSS voltage sensors ffrom Frsky would be able to accurately measure the voltage of a 2s LiFePo4 battery? I am partcularly interested in measuring the low voltage (battery nearly empty!) state. Many thanks.

It's not a battery type that we've used before so can't be 100%, but it should work as it's compatible with 6 - 25V - I believe LiFePo4 is 3.2V per cell?
