MORE DATA CAPTURED: Displays the state of charge, remaining battery capacity (up to 999Ah), charge and discharge current (A), voltage (V), and low voltage alarm. This information helps optimize battery usage, enhancing battery lifespan and reducing the risk of failure. MULTIPLE USES: Compatible with various battery types including lithium, LiFePO4, lead-acid, and others, supporting current range 10A-100A and voltage range 9.5-100V. Suitable for RVs, golf carts, fishing boats, electric scooters, solar panels, and more. Features a waterproof battery monitor with shunt. WIRING WITH SHUNT: The shunt is constructed from solid copper with low resistance to minimize energy loss during measurements. It supports currents up to 100A. Includes a 3-meter (9.85 feet) shielded cable for enhanced signal stability and interference protection. DATA STORAGE: Offers zero/full capacity setting for Voltage, Ah, Capacity, and Current. Automatically stores the last measurement when the system powers off. DISPLAY: Equipped with a digital LCD display with backlight and a reinforced acrylic waterproof cover. Shows V, Ah, A, SoC, and a remaining capacity bar for clear battery status indication. LOW VOLTAGE ALARM: Optional low voltage alarm activates when battery voltage drops below the preset level. Display digits flash to alert the user that the battery needs charging. LOW POWER CONSUMPTION: The battery monitor has minimal power draw; normal mode consumption is under 15mA, while sleep mode is under 1mA. Color: Black Material: Plastic Package Contents: 1 x Battery Monitor Note: Light reflection and differences in display settings may cause slight variations between the product color in images and actual color. Measurement error allowance is +/- 1-3cm.
