precision voltage and current measurement: The BL140F Battery Monitor is equipped with a precision current detector to provide accurate voltage and current readings for your battery system. Clear markings and robust construction: The negative terminals of batteries and loads are clearly marked, and the monitor with shunt uses pure copper and heavyduty connectors for durable, reliable performance. Optimized monitor interface: The monitor interface has been redesigned with larger, clearer text, making it easy to read essential information such as charge, discharge, amperage, and wattage at a glance. Color screen with capacity percentage: The color display shows the remaining capacity as a percentage without scrolling, and uses green to indicate normal capacity and red to indicate low capacity. Practical use scenarios: Offgrid solar installations: Monitor the battery bank during charging and discharging to optimize energy use and protect battery health. RV or marine applications: Track state of charge during travel or boating to ensure critical systems stay powered. Backup power systems: Realtime visibility of charge and discharge helps manage UPS or generatorbacked setups reliably.
