The FrSKY Battery Voltage Sensor is used with the FrSKY telemetry system. No hub is required to use this sensor. (Receiver must support external sensors.)
There are three voltage ranges to choose:
Please check the battery voltage division ratio for each option:
2S - 3S 4:1
3S - 5S 6:1
Does not work with X8R receiver (see analog voltage sensor for this application).
Does work with: D8R-II Plus and XP, D4R-II, XSR, X4R, X6R and most Archer and newer receivers that feature an AIN2 port.
