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 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 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 measurement and can handle currents up to 100A. Includes a 3-meter (9.85 feet) shielded cable for enhanced signal stability and interference prevention. DATA STORAGE: Offers zero and full capacity setting functions for voltage, Ah, capacity, and current. Automatically stores the last recorded data when the system powers down. DISPLAY: Equipped with a digital LCD display with backlight and a reinforced acrylic waterproof screen. Shows voltage (V), ampere-hours (Ah), current (A), state of charge (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 threshold. Display digits flash to alert the user that the battery requires charging. LOW POWER CONSUMPTION: Designed for minimal power draw; typical operating current consumption is under 15mA, while sleep mode consumption is less than 1mA.
