2-Pack 7-55V DC Battery Indicator

This two-piece set provides white LED voltage readouts for 7-55V DC systems. It suits installers and hobbyists who need a compact monitor for Lithium-ion, LiFePO4 or Lead-Acid batteries in automotive, solar or DIY builds. Each module measures 46 by 15 by 3 millimetres for a slim profile.

Upgrade from basic gauges

Replaces simple analogue meters or fixed-range indicators that lack memory or alarm functions. The jump is worthwhile when you need custom high and low voltage thresholds for 12, 24, 36 or 48 volt Lead-Acid packs, 3S-12S Lithium-ion or 3S-14S LiFePO4 configurations. Settings survive power loss without re-entry.

Capacity and headroom

Comfortably tracks state of charge across the full 7-55V window with a bright white display readable in daylight. The adjustable backlight timer reduces draw during long-term logging. It runs out of range below 7 volts or above 55 volts, and it does not log history or communicate data externally.

Questions about this item

What are the exact dimensions I need for a cut-out to mount the 46x15x3mm module?

Cut a rectangular opening 46 mm long by 15 mm wide; the module is only 3 mm thick so it sits almost flush against the panel.

Which wires do I connect first to avoid losing the custom voltage settings during installation?

Apply 7-55 V DC to the power terminals before wiring the signal leads; the built-in memory keeps your battery-type and backlight choices once power is live.

When should I expect to replace the white LED backlight in a 12 V automotive gauge cluster?

The white LEDs are rated for tens of thousands of hours; in typical 12 V dash use they will outlast the vehicle’s instrument panel.
