The 3S 18650 12V Lithium Battery Capacity Indicator Module is an essential tool for monitoring the charge level of 3S (3-series) 18650 lithium batteries. This module is designed to provide a clear, real-time display of the battery's power level, indicating its capacity as a percentage using an LED display. It operates on a 12V system, which is ideal for powering devices and projects that require a 12V power source. The module uses a precise voltage monitoring system to estimate the remaining charge of the connected lithium battery pack, and the LED bar or numerical display shows the current state of charge. This makes it particularly useful for battery-powered systems such as power banks, electric vehicles, robotics, and more. With an easy-to-read design, it ensures efficient battery management and helps avoid unexpected power losses.
