3S 11.1V Battery Level Indicator 18650 Lithium Battery Capacity Tester and Percentage Detection Monitor

A 3S Battery Level Indicator is a device designed to monitor and display the charge level of 3-series (3S) lithium-ion battery packs, commonly composed of 18650 cells. These indicators provide real-time information on the remaining battery capacity, aiding in efficient power management for various applications. 

To use the indicator, connect its positive and negative terminals to the corresponding terminals of the 3S battery pack. The LED display will then illuminate to show the current charge level, typically divided into segments indicating ranges such as 0-25%, 25-50%, 50-75%, and 75-100%. 

 

Features: 

1. Battery Compatibility: Specifically designed for 3S lithium-ion battery packs, typically rated at 11.1V or 12.6V when fully charged. 
2. LED Display: Utilizes a series of LEDs to represent different charge levels, allowing for quick visual assessment of the battery's state. 
3. Low Power Consumption: Engineered to consume minimal power during operation, ensuring that the indicator does not significantly drain the battery. 
4. Reverse Polarity Protection: Equipped with protection features to prevent damage in case of incorrect wiring or reverse polarity connections.
