LED Battery Level Indicator for 3S Li-Ion (12.6V) with Test Button
LED battery level indicator for 3S Li-Ion batteries. Displays charge status through four bright LED lights. A simple push-button instantly shows the remaining battery capacity. Perfect for e-scooters, power banks, solar setups or DIY electronics.
This compact LED battery level indicator is designed for 3S Li-Ion battery packs with a full charge voltage of 12.6 V. When the test button is pressed, it displays the current charge level using four clear LED segments, indicating 25%, 50%, 75%, or 100% battery capacity. The module operates in a voltage range of approximately 9 to 13 volts and consumes minimal current, around 5 mA.
Its small size makes it easy to integrate into compact projects. The PCB measures approximately 44 × 17 mm, while the front plastic panel is about 31 × 20 × 8 mm. It is built for environments with operating temperatures from −20 °C to +50 °C.
Power is supplied directly from the battery, with no additional power source needed. This module is ideal for monitoring battery status in portable electronics, e-scooters, solar systems, battery boxes and other low-voltage applications.
If you need a clear, reliable and easy-to-use way to monitor your 3S Li-Ion battery, this indicator is the perfect solution.
