Onboard 5V stabilizing chip delivers continuous current up to 5A, enabling power for a Raspberry Pi or other devices with sufficient power. Realtime monitoring via I2C: measure battery current, total power, and remaining power to detect the module's operation status quickly and accurately. Onboard reverse polarity warning: easy to check and prevent incorrect battery installation, helping protect the system. Includes a supporting information manual to assist setup, configuration, and usage. Practical applications Power a Raspberry Pi or similar singleboard computers and ensure stable 5V supply for smooth operation. Batterypowered projects and portable devices that require live current, power, and remaining energy readings for monitoring and alerting. Development, testing, and diagnostic setups where I2Cbased parameter monitoring and quick verification of correct battery connection are beneficial.
