Connected Detector -RC 100A/150A Watt Meter Power Analyzer, High Accuracy 100A Battery Voltage : Digital LCD display: easy to read, the LCD display provides a clear digital reading. And a real-time reading: the power meter will constantly provide a real-time reading of amps, 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 is essential for analyzing, testing and troubleshooting any DIY DC power supply project. Multi-tool: Check that there is sufficient working voltage under load. Avoid peak current damaging batteries, ESC, motors, wiring and connectors. \ Check battery charger for proper operation (connect your battery and charger). Individual cells are balanced. the cut-off voltage and check the battery capacity. Detect the receiver and the actual working current to determine whether UBEC, etc. The Professional RC Power Meter is a great addition to your RC hobby, DC circuits, solar system, boats/RVs and battery backup systems.
