SHMZK 2 PCS 0.28" Digital Voltmeter Ammeter, DC 0-100V 10A 2 in 1 Volt Amp Meter with Connect Wires, Red & Blue Dual LED Display Panel Current Tester Voltage Gauge for EV Car Boat (10A)

Precision Monitor: Our LED voltage and current meter is specifically designed for accurate measurement of vehicle voltage and current. By monitoring the vehicle voltage and current conditions in real-time, you can ensure optimal protection for your car battery and extend its service time

LED Digital Display: Featuring a dual-color LED digital display, this voltage and current meter uses red to indicate voltage and blue for current. This intuitive design allows voltage and current readings to be displayed simultaneously, making them easy to read and distinguish

Reliable Material: Constructed with premium plastic housing and a durable electric board, our meter offers excellent rust and corrosion resistance for long-term use. It operates effectively across a temperature range of -10°C to 65°C, ensuring stable performance under various conditions

Product Specification: It measures 1.88"×1.14"×0.86", with a working voltage of DC 4-30V. It can quickly and accurately measure voltage in the range of 0-100V and current in the range of 0-10A. It also has a refresh rate of approximately 300 ms and a current consumption of ≤20 mA. Just to clarify, the 50A and 100A voltmeters need external shunt resistors to work, but we don’t supply it

Wide Compatibility: This voltage and current meter is easy to connect and versatile in application. It is ideal for use with electric vehicles, motorcycles, boats, and more, and is commonly used for monitoring voltage and current conditions in batteries, DC power supplies, or other devices
