Usage Tips: Our power meter can capture a range of basic data, including cumulative capacity in Wh (watt-hour) and Ah (ampere-hour) over a long period of time, real-time current (I), real-time power (W), and real-time voltage (U). This device is designed to measure the charge and discharge capacity of RC lipo batteries. Screen: 1.5 inches, LCD Refresh rate: 3Hz Voltage range: 8–150V Continuous current: 25A (instantaneous 50A for up to 3 seconds) Accuracy: Less than 0.2% Interface: Gold-plated XT60 Test resolution: 0.001V/0.001A Note: 1. Prolonged operation above 25A may affect measurement accuracy. 2. The device does not operate below 8V and cannot measure voltages below this threshold. 3. To maintain accuracy, avoid modifying the product. Each unit is factory calibrated for optimal performance. Use the provided XT60 connector for safe wiring. 4. The analyzer supports both charging and discharging; the display shows positive or negative current accordingly. 5. Press the reset button to switch display interfaces; hold to reset cumulative capacity to zero.
