Description :

-The Gravity I2C 3.7V Lithium Battery Fuel Gauge is a device that accurately measures the voltage and remaining power of a 3.7V lithium battery.
-It uses a Gravity I2C interface and has ultra-low operating current.
-The module uses Maxim’s patented algorithm to track the relative state of charge (SOC) of the battery in real-time, eliminating the need for full-to-empty relearning and offset accumulation errors.
-The module has a low battery power alert interrupt function that generates a falling pulse when the battery power falls below a specified threshold.
-The module is useful in solar-powered projects, as it helps to record the status of the battery power change over time, which can help to understand the power balance of charge and discharge of the solar system.
