100A Current and Voltage meter with 100A shunt

The 100A Digital DC Voltmeter and Ammeter with 100A Shunt is a high-precision measuring instrument designed to monitor both current and voltage in real time. Featuring a dual-color LED display (red for voltage, blue for current), it provides instant visibility into power system performance.

With the included external 100A shunt, this meter is capable of handling large current loads safely and accurately. Its wide voltage measuring range (0–100V) and operating voltage (4–30V DC) make it suitable for a variety of high-power DIY and industrial applications including solar panels, battery banks, and EV systems.

⚠️ Note: Best suited for measuring currents above 1A. Using it below 1A may lead to inaccurate readings.
