Gravity: I2C 3.7V Li Battery Fuel Gauge is a module for monitoring the parameters of the Li-ion battery allowing for precise measurement of the flow of charge to / from a 1-source source with an input voltage of 2.5-4.2V. DFRobot DFR0563
Gravity: I2C 3.7V Li Battery Fuel Gauge is a Li-ion battery parameter control module. The module can control the status of a 1-purpose power source. Thanks to the precise measurement of the flow of electrical charge to and from the battery and the advanced algorithm, it is possible to determine the exact level of the battery charge. The system has a built-in system for eliminating offset errors and the ability to set a low-battery notification. The module has Gravity connectors and is easy to use with popular development kits. Communication with the module takes place via the I2C interface. It can be used in projects that require battery status control, eg in solar systems.
