BATT-MON Click Mikroe BATT-MON Click is a very versatile, high accuracy, multiple-chemistry battery gauge for single-cell battery applications. The click is used for various applications, ranging from smartphones, notebooks / laptops, power tools, and vacuums, to energy storage systems (ESS). It provides the output voltage at the same time and can provide additional current to the connected load if the current provided from the mikroBUS™ socket is not enough. This is possible by utilizing the connected battery and employing intelligent power routing algorithms of the BATT-MON click.
