Accurate Battery State Detection Uses an advanced algorithm to precisely measure battery voltage and detect the relative state of charge. This helps you know remaining capacity and battery health at a glance. Alert Function Features an alert pin that signals when the battery drops below a userdefined percentage, enabling proactive monitoring and notifications to prevent unexpected power loss. Suitable for Liion Batteries Specifically designed for monitoring a single Liion battery, providing focused and reliable state tracking for onecell applications. Easy Reset Options Offers both hardware and software reset capabilities for convenient recalibration and straightforward maintenance of your battery system. 23 Practical Use Scenarios Hobby electronics and RC projects using a single Liion cell: monitor voltage and receive a lowbattery alert during operation to avoid surprise shutdowns. Portable tools or sensors powered by a single Liion cell: track battery state to prevent unexpected shutdowns and help extend usable life. Educational or tinkering setups: demonstrate battery state monitoring with practical reset options for repeated experiments and learning.
