LED Battery Meter 12V-72V Power Monitor | Waterproof Battery Gauge for RV Golf Cart Boat

Monitor your battery's remaining power at a glance with this versatile LED battery meter. Designed to work with 12V, 24V, 36V, 48V, 60V, and 72V battery systems, this waterproof gauge gives you a clear, real-time readout of your battery level whether you are charging or discharging.

This battery power monitor is built for reliability and ease of use. It automatically detects your battery voltage upon connection and refreshes its reading every 10 seconds, so you always know exactly how much power you have left. The 10-segment LED display uses three colors — red, yellow, and green — to give you a quick visual reference of your battery's state of charge.

Made from durable ABS material with an IP53 waterproof rating, this gauge is suitable for outdoor and vehicle use. It works with a wide range of battery types including ternary lithium, polymer lithium-ion, lithium-ion, storage batteries, and water batteries. Installation is straightforward with a standard panel cut-out, and you can choose between direct or key switch wiring.

Whether you are managing power on a golf cart, RV, boat, or car, this LED battery indicator helps you avoid unexpected power loss and keeps your equipment running smoothly.
