12S 44.4V Battery Level Indicator 18650 Lithium Battery Capacity Tester and Percentage Detection Monitor

A 12S Battery Level Indicator is designed to monitor and display the charge status of 12-series (12S) lithium-ion battery packs, commonly assembled from 18650 cells. These indicators provide real-time insights into the battery's remaining capacity, facilitating effective power management in various applications. 

To use the indicator, connect its positive and negative terminals to the corresponding terminals of the 12S battery pack. Upon activation, the display will show the current charge level, typically divided into segments indicating ranges such as 25%, 50%, 75%, and 100%. 

Features: 

1. Battery Compatibility: Tailored for 12S lithium-ion battery packs, which typically have a nominal voltage of 44.4V and a fully charged voltage of 50.4V. 
2. Display Options: Available in various formats, including LED bars and LCD screens, to represent different charge levels, allowing for a quick visual assessment of the battery's state. 
3. Low Power Consumption: Designed to consume minimal power during operation, ensuring that the indicator does not significantly drain the battery. 
4. Reverse Polarity Protection: Includes protection features to prevent damage in case of incorrect wiring or reverse polarity connections.
