4.5-30V Red LED Digital Voltmeter Panel Mount DC Battery Monitor

Keep an eye on your DC voltage at a glance. This compact red LED digital voltmeter is designed for direct panel mounting - no external power supply required. It draws its operating power from the circuit being measured, making it a clean, no-fuss solution for battery monitoring, solar systems, automotive dashboards, and DIY electronics projects.

The bright 0.56" three-digit LED display is easy to read in all lighting conditions, and the 1% accuracy makes it reliable enough for everyday monitoring use. At just 18g and with a compact 48 x 29 x 22mm body, it fits neatly into standard panel cutouts and takes up minimal space.

Key Features:

• Measuring range: 4.5V to 30V DC - ideal for 6V, 12V, and 24V battery systems
• No external power supply needed - powered directly by the circuit under test
• Bright red 0.56" 3-digit LED display - easily visible in daylight and low-light conditions
• 1% accuracy ( 0.3V at 10V; 0.10V at <10V) for reliable voltage monitoring
• Fast 300ms refresh rate - near real-time voltage readings
• Panel-mount design with 46 x 27mm cutout size - fits standard project enclosures
• Input impedance >100k - minimal load on the circuit under test
• Operating temperature: -20 C to +65 C - suitable for indoor and outdoor installations
• Compact and lightweight: 48 x 29 x 22mm body, only 18g
• Lead length: 20cm - enough reach for most panel installations

Ideal Applications:

Perfect for 12V/24V battery banks and solar charge monitoring, automotive and caravan voltage displays, DIY electronics and Arduino projects, UPS and backup power monitoring, and any DC circuit where a clean, simple voltage readout is needed.
