Description: Digital LCD Screen Display: easy to read the LCD provides clear digital reading.And reading: the wattmeter will continuously provide reading of amperes, volts, and watts after connection. Provides 8 Electrical Readings: Current (A), Voltage (V), Watts (W), Amp-hours (Ah), Watt-hours (Wh), Peak Amps (Ap), Minimum Volts (Vm), Peak Watts (Wp). Perfect troubleshooting tool: it's indispensable for analyzing, testing and troubleshooting any DIY DC power project. Multi-functional tool: verify that there is sufficient working voltage under load.Prevent peak current from damaging batteries, ESC, motors, wiring and connectors.\Verify correct battery charger operation (connect your battery and charger).Individual cells are balanced.Set the cut-off voltage and check the battery capacity. Detect the receiver and the actual operating current to determine whether , etc. Watt Meter is an excellent addition to your RC hobby, DC circuits, Solar system, Boat/RV & Battery Backup systems.
