This is Red-Blue LED Digital Dual DC 100V 100A Ammeter Voltmeter. This meter will measure up to 100 VDC with a 0.1-volt resolution. One thing to note is, this meter has 2 wiring harnesses.
One harness is to provide power for the meters, that’s the 2 poles with a RED and a BLACK lead. Small size, portable, the magnitudes of voltage and current are displayed on the same screen at the same time.
This can be supplied anywhere from 6 volts DC up to 30 VDC. Maximum Input Voltage should not exceed 30V otherwise there is a danger of burning
Note : Shunt resistor is not included with this product

This digital ammeter has been a great addition to my project.
I've been using this digital voltmeter for a few weeks now, and it has been working great. The readings are accurate, and I love the compact design
This digital voltmeter is an excellent tool for monitoring voltage and current in my DIY projects. I was impressed with the quality of the product and it was very easy to install.
Hello! A shunt is a low-resistance precision resistor used in measuring electric current. When used in a voltmeter-ammeter panel, the shunt allows the device to measure high currents by producing a small, proportional voltage drop that the meter can read and convert into a current measurement. Thank You
Hello, It will show current if the load is less than 1 amp. if your project requires more accuracy and sensitivity then please look into some current sensors.
Hello, Digital Voltmeter Ammeter DC 100V 100A Dual Led Voltage Monitor Panel (Without Shunt) requires an external shunt. Thank You
Please refer to the connection diagram shown in below link https://i.stack.imgur.com/REeFi.png
Hello, the digital voltmeter ammeter you linked does not have an inbuilt shunt to measure up to 100A DC current. You will need an external shunt to measure such high currents. Thank you.
Hello, yes, a shunt is required for measuring current up to 100A with the digital voltmeter ammeter you linked. The shunt is necessary to accurately measure high currents by providing a precise voltage drop that the meter can read. Thank you.
