Dual Pro Battery Fuel Gauges

Know Your Real Battery Status

Most battery indicators on golf carts or boats are simple voltmeters. The problem is that battery voltage can drop under a heavy load and then bounce back when the motor is off, giving you a false sense of security. Dual Pro gauges use advanced algorithms to track the energy going in and out, providing a true reflection of your battery's capacity.

Clear and Simple Reading

You shouldn't need a manual to understand your battery level. These gauges feature a bright, 9-LED display that is easy to read even in direct sunlight.

• Green LEDs: Indicate a healthy, full charge.
• Amber LEDs: Let you know you are moving into the middle of your capacity.
• Red LEDs: Act as a clear warning that it is time to head back to the charger.

Smartphone Monitoring with PROView Link

Many Dual Pro fuel gauges are compatible with the PROView Link system. This allows you to sync the gauge with a free app on your smartphone via Bluetooth. It is a fantastic feature for those who want to see their exact battery percentage and health without having to be right next to the dashboard or battery box.

Built for the Long Haul

Whether you are installing a gauge on a bass boat, a golf cart, or a piece of industrial floor equipment, these units are built to last. They are water-resistant and designed to fit into a standard 2-inch mounting hole, making them a perfect replacement for older, less accurate gauges. We carry models for almost any setup, including 12V, 24V, 36V, 48V, and even 72V systems.

Frequently Asked Questions

Is this gauge easy to install?

Yes. These gauges are designed for a standard 2-inch cutout, which is the most common size for marine and automotive dashboards. They typically require a simple connection to your battery pack and come with clear instructions to get you up and running quickly.

Does it work with Lithium batteries?

Dual Pro offers specific models designed for different battery chemistries. While some models are built for traditional Lead-Acid or AGM batteries, others are specifically calibrated for the unique discharge curve of Lithium (LiFePO4) batteries. Be sure to select the model that matches your battery type for the best accuracy.

Can I see the gauge in the dark?

Yes. The LED lights are bright and easy to see in low-light conditions or at night, but they are also designed to be visible in the bright glare of a sunny day on the water.

Will it drain my battery if I leave it on?

These gauges are designed with very low power consumption. They draw a negligible amount of energy to keep the display and monitoring systems active, so they won't significantly impact your battery life during normal use or short-term storage.
