Standby time: Actual standby time is up to 6 hours under test conditions of open networking and updates of power parameters every 2 seconds. This enables longer unattended testing sessions without frequent recharging. Power control: Low onresistance power control reduces energy loss, improving battery efficiency and extending battery life. Fuel gauge integration: This board integrates a MAX17040G fuel gauge chip with 1000 mAh per chip. Using thimbled mounting, it offers simple and neat integration. Firmware and power circuit optimization: Version V1.2 removes a rarely used function and optimizes the battery power supply circuit for improved reliability and efficiency. Use scenario 1: Portable, batterypowered test setups in opennetwork environments where frequent powerparameter reporting occurs, allowing longer operation between charges. Use scenario 2: Development and field testing of batterypowered devices that rely on accurate fuel gauging and efficient power management. Use scenario 3: Educational labs or demonstrations focusing on battery management and MAX17040G integration, providing clear, realworld insights into power consumption and measurement.
