12V 24V Battery Monitor

This digital voltage gauge tracks battery state on 12V and 24V DC systems. It suits cars, trucks, RVs, boats, ATVs and similar vehicles. The blue LED display shows voltage from 5 to 48V with 0.1V accuracy. It helps prevent unexpected drain and extends battery life.

Surface Mount Wiring Kit

The package includes a mounting plate, round nut, screws, insulated terminals and a 23.8-inch cable with red positive and black negative leads. Installation is a simple surface mount with basic tools. Copper wiring and a built-in fuse protect against overcurrent, overvoltage and short circuits. Incorrect polarity or loose terminals are the common wiring errors.

5-48V Range 0.1V Accuracy

The meter reads 5V to 48V, covering healthy and depleted states on 12V and 24V systems. It provides clear visibility in bright sun or darkness. It cannot measure AC voltage or currents above the fused limit. Systems outside the 5-48V window need a different instrument.

Questions about this item

How can I verify the gauge is reading correctly once it is wired up?

After installation, the three-digit LED display should show a value between 5 and 48 V with 0.1 V resolution, changing smoothly as the engine starts or loads are switched on.

What parts come in the package and what must I supply myself?

Included are a surface mounting plate, round nut, two screws, two insulated terminals and a 23.8-inch cable with red positive and black negative leads; you only need basic hand tools and a 12 V or 24 V DC power source.

Which voltage version should I select for my vehicle?

The single unit covers both 12 V and 24 V DC systems, so no separate version choice is required.
