- Wide Voltage Range: Acts as a precision voltage meter and power monitor with 4.8–60 V input, suitable for single-cell LiPo to large multi-cell packs. The integrated current sense resistor handles up to 100 A (with optional high-amp shunt), measuring power usage and helping prevent pack over-discharge. - Digital Display: A wattage meter with a backlit LCD that shows voltage, current, power, and capacity in real time. The user-friendly interface lets you switch display modes and track session data, readable in bright sun or low light. - RC Compatibility: Designed for RC model airplanes, helicopters, cars, and drones. Integrates into flight packs and drive systems, providing live updates on power draw to optimize motor performance and avoid overloading during aggressive maneuvers. - High-Precision Analysis: Features a high-accuracy ADC and temperature-compensated shunt for measurement stability. The compact PCB and robust connectors deliver low insertion loss, achieving up to 0.1% reading accuracy for fine-tuned energy management. Use scenarios: - While piloting a high-power RC plane or drone, monitor real-time voltage, current, and remaining capacity to protect the battery and maintain performance. - In a racing RC car or helicopter, track power draw during hard acceleration to prevent overloading and optimize motor response. - During long sessions, rely on stable, precise readings to manage energy use and schedule timely battery maintenance or discharges.
