ToolkitRC WM150 Advanced Watt & Power Meter

The ToolkitRC WM150 is a precision inline watt meter and power analyzer designed for evaluating drone power systems on the bench. Built for checking amp draw, power consumption, and battery voltage sag during static thrust tests, it safely handles high-current setups up to 150A. By sitting between your LiPo battery and the ESC or power distribution board, it provides real-time telemetry on system loads, helping builders prevent burnt components or overloaded batteries before taking flight.

Key features

• Measures and logs real-time voltage, current, peak power, and total capacity drained.
• High-load capacity supporting up to 50V (up to 12S LiPo) and 150A maximum current, measured to 10mA precision.
• Integrated PWM signal generator allows direct ESC and motor spin-up without a flight controller or radio receiver.
• Bright 2.4-inch colour TFT display plots real-time voltage and current graphs.
• Pre-soldered XT60 input and output connectors for immediate inline testing.
