200a High Precision Power Analyzer Convenient To Calculate The Voltage, Current, Power, Discharge Amount And Discharge Time Of The Aircraft, And Calculate The Force Effect Of The Multi-axis Aircraft. Current: 0-200a, Continuous Current 50a, Resolution 0.01a. Operates From 4.8-60v (when The Test Voltage Is Lower Than 5v, A Separate 12v Power Supply Is Required To Power The Power Meter), Resolution 0.01v. Measures 0-6554wh, Resolution 0.01wh. The Current Can Determine The Battery Capacity, The Continuous Current Can Determine The Discharge Time, And The Maximum Instantaneous Current Can Determine The Internal Structure Of The Battery To Protect Circuit. Watt Meter Power Analyzer Can Verify Sufficient Operating Voltage Under Load And Prevent Peak Currents Damaging Battery, Motor Control, Motors, Wiring And Connectors; Verify Correct Battery Charger Operation (connect Your Battery And Charger); Set The Cut-off Voltage And Check The Battery Capacity; Detect The Receiver And The Actual Operating Current To Det
