Want to keep a close eye on your electrical system? This combo includes a dual LED digital voltmeter and a matching 50A/75mV shunt resistor. The meter measures voltage from 4.5V up to 30V DC, perfect for 12V or 24V vehicle, solar, or battery systems. The shunt resistor is the key—when you wire it in line with your load, it allows the meter to also display current draw (up to 50A). So you can see both voltage AND amperage on one display! It's brand new, unbranded, and made in China. Great for monitoring car audio systems, RV batteries, solar panels, DIY power supplies, or any project where you need to know how much power is being used. The shunt has a low 75mV drop, which is standard. Installation requires some basic wiring skills: connect the shunt in the negative line to the battery, then wire the meter to the shunt and a power source. A super handy tool for troubleshooting, optimizing, or just geeking out over your electrical setup. Knowledge is power—literally!
