Functional characteristics This LCD battery power display features a digital voltmeter designed to detect the voltage of various battery types, including lithium, iron, and leadacid batteries. It has a wide working voltage range of DC 10V to DC 100V, making it suitable for a variety of applications. Hard protection shields the internal components from external impacts, improving the overall reliability of the voltmeter. Ultralow power consumption design provides energy efficiency, reducing battery drain and extending battery life. Includes a key switch for easy configuration and a time adjustable feature to set the display duration according to user preferences or specific requirements. Practical use scenarios Monitoring battery banks in solar power and offgrid systems, allowing quick assessment of voltage across different battery chemistries. Checking voltage in automotive, ebike, or portable power applications to prevent unexpected power losses and plan maintenance. Used in DIY electronics projects or educational settings to observe and compare voltages of lithium, iron, and leadacid batteries with minimal power draw.
