The FrSky Ampere Sensor (FAS-40) can measure Current (A), Power Consumption (mAH) and Power (W) when connected between a Battery and ESC. Current (A) and Power (W) will be displayed on the FLD-02, while Current (A) and Power Consumption (mAH) will be displayed on the DHT-U. The FAS-40 reports Power and Power Consumption without an external voltage sensor and, in addition it can be chained together to report individual cell voltages by using the Lipo Voltage Sensor (FLVS-01).
