GP Dual Digital Voltage Meter: Main & Auxiliary Battery Monitor

GP Dual Digital Voltage Meter – Main & Auxiliary Battery Monitor

Keep an eye on two electrical systems at the same time with the GP Dual Digital Voltage Meter. Designed for vehicles and high-performance electrical systems using a main battery and auxiliary battery bank, this compact gauge provides two independent voltage readings in one clean, easy-to-install display.

The dual LED readout lets you monitor MAIN and AUX voltage simultaneously, making it easy to spot voltage drop, charging issues, or differences between your starting battery and secondary battery bank. It’s an excellent addition to high-performance car audio systems, where knowing the condition of both electrical systems can help protect your equipment and identify problems before voltage gets dangerously low.

Perfect for High-Power Car Audio

Running a secondary battery or lithium bank for your amplifier system? The GP Dual Voltage Meter gives you a quick visual reference of both your main vehicle electrical system and your auxiliary bank from a single gauge. Instead of installing two separate voltmeters, you get both readings in one compact display.

Two systems. One gauge. Know your voltage.
