Li-Ion 3S Battery Percentage Indicator Module
The Li-Ion 3S Battery Percentage Indicator Module is a compact battery voltage monitoring module designed for 3S Li-Ion battery packs. It uses a row of LED indicators to provide a quick visual indication of the battery’s approximate charge level, making it easy to monitor battery status without requiring a multimeter or dedicated display.
The module is designed for battery packs with a nominal voltage of approximately 11.1V and a fully charged voltage of 12.6V. It features a simple two-wire connection, with red and black wires used for positive and negative battery connections. The built-in TEST button activates the LED display, helping reduce unnecessary battery consumption when the indicator is not being checked.
