The latest sensor developed by FrSKY has been designed to collect important flight information and performance data which can be transmitted via the smart port of telemetry-enabled receivers such as X8R, X6R, X4R, etc to a Taranis transmitter .
This particular sensor is used to monitor the voltages of LiPo packs. The latest sensor incorporates a colourful easy-to-read (even in the dark!) OLED (organic light-emitting diode) display showing both total voltage and individual cell voltages. Simply plug in your LiPo balance plug to view the voltage readings.
The sensor can also be used as a handy, pocket-size, stand-alone LiPo checker.
• Accurate display of LiPo cell voltages
• Clear OLED disply - can even be read in the dark!
• Light weight - only 5.2g
• Compatible with FrSky Smart Port enabled receivers, such as X8R, X6R, X4R, etc.

This doesn't work for 1S as advertised, at least not when they're at or below storage voltage. I also have the old version that does work on 1S, even at 3.6V.
So I guess the Smart Port chip requires a minimal voltage that is somewhere above a low charged 1S cell (minus some regulator drop off).
This new version curiously also has a start up delay of about 1 second.Connecting it was really easy.
However getting all the cells to read in my TX was a bit of a hassle since there was a new version of open TX out since everyone did their guides on youtube.This voltage sensor you must have it monitors your batter individual cells and alert you when batter is low.These are superb & although the impressive, bright, clear display screen might be a non-essential for a telemetry module, it's reassuring to see that the telemetry read-out received / displayed at the transmitter is always identical to the telemetry module display & its a bonus to be able to see the cell voltages when looking into the model... At $15 I can't see how these modules might be sold for very much less without it.
.... My latest project has two of these in tandem (one reconfigured from port #2 to port #6), connected to X8R receiver Smart port - monitoring 10S LiFe pack comprising two 5S packs in series. They're mounted so that the voltage displays can be seen through the cockpit window.
Works great after doing a hell of a research grinding through online forums just to figure out the basics about how this thing works. I HATE YOU FRSKY for being such lazy ignorant pack, not being able to put together even a minimal documentation for your products!!! The frustration was unbearable, but there is a reward: The joy of discovery apart from having a wonderful system.
The readings are accurate, the display is gorgeous, the paper wrapping is disgusting.Very nice little unit. My first Smartport device and really like it. Agree with others that Frsky should make something similar without a display and as inexpensive as possible so we can load them in all of our aircraft.A must have sensor for my X8R Rx.Praxistest fehlt nochExcellent sensor! Very small and lightweight. WARNING: Works on SmartPort receivers only! It can also be used as an autonomous battery cell checker because it has a built in display. I love this product!I bought one for my X8R, outside EU warehouse and it was worth it. I now have an amazing sensor for my LiPo 6S, great display (no problems here) and most of all i get peace of mind. No more worrying about time, trying to hear the alarm buzzer. With a flick of a switch on my FrSky radio and ... Bam! Minimum Cell voltage, Total Voltage and so on. Great product no doubt.
