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, and lead-acid, supporting current levels from 10A to 100A and voltage range from 9.5V to 100V. Suitable for use in RVs, golf carts, fishing boats, electric scooters, solar power systems, and more. Features a waterproof battery monitor with included shunt. WIRING WITH SHUNT: The shunt is constructed from solid copper with low resistance to minimize energy loss during measurement and can handle currents up to 100A. Includes a 3-meter (9.85 feet) shielded cable for improved signal stability and reduced interference. DATA STORAGE: Offers zero and full capacity setting functions for voltage, Ah, capacity, and current. Automatically stores the most recent measurement data when the system powers down. DISPLAY: Equipped with a digital LCD display with backlight and a reinforced acrylic waterproof screen. Shows voltage, amp-hours, current, state of charge (SoC), and a remaining capacity bar graph for clear battery status visibility. LOW VOLTAGE ALARM: Optional low voltage alert activates when battery voltage drops below the preset threshold. Display digits flash to indicate the battery requires charging. LOW POWER CONSUMPTION: Designed for minimal power draw; operating mode consumes less than 15mA, while sleep mode uses under 1mA. Color: Black Material: Plastic Package Contents: 1 x Battery Monitor Note: Light reflection and differences in display screens may cause slight variations between the color of the item in images and the actual product. Measurement may vary by +/- 1-3cm.
