The 12V–72V Lead Acid Battery Capacity Indicator is an electronic battery-monitoring module designed to display the approximate charge level of lead-acid battery systems. It helps users quickly check battery status through a visual LED display or a digital indicator, depending on the model.

Supporting nominal battery systems from 12V to 72V, this module is useful for monitoring batteries in electric bicycles, electric scooters, solar energy storage systems, backup power supplies, and other battery-powered equipment. It allows users to estimate when a battery needs charging and helps prevent unexpected power loss.

Key Features

Wide voltage compatibility: Designed for nominal 12V, 24V, 36V, 48V, 60V, and 72V battery systems, depending on the model.
Visual battery-level display: Shows approximate remaining capacity using LED segments or a digital display.
Simple monitoring: Allows users to check battery status without specialized testing equipment.
Compact design: Easy to integrate into battery enclosures, control panels, and electronic projects.
Low-power operation: Typically consumes little power, depending on the indicator design.
Multiple applications: Suitable for lead-acid batteries used in solar, automotive, and electric mobility systems.
