## Description

The Adafruit LC709203F Fuel Gauge monitors your single-cell LiPo or Li-Ion battery and reports both voltage and state of charge as a percentage over I2C. It handles the non-linear voltage-to-percentage conversion for you, so your project always knows exactly how much battery is left — just like the battery indicator on your phone. With dual JST PH connectors for battery passthrough and STEMMA QT / Qwiic connectors for solderless I2C wiring, this breakout is easy to integrate into any project. It works with 3.3V or 5V power and logic, and supports an optional thermistor for battery temperature monitoring. Key Features Battery Percentage Readout – Converts non-linear battery voltage to accurate state-of-charge percentage Cell Voltage Monitoring – Reports real-time battery voltage over I2C Configurable Pack Size – Set battery capacity for improved percentage accuracy Dual JST PH Connectors – Battery passthrough for easy inline integration STEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support 3.3V & 5V Compatible – Works with Arduino, Feather, Raspberry Pi, and more Optional Thermistor Input – Connect a 10K thermistor for battery temperature monitoring Single-Cell Only – Designed for 3.7V LiPo / Li-Ion cells Ideal For Battery-powered projects needing accurate fuel gauge readings Feather and portable builds with LiPo battery monitoring IoT devices that need to report battery level Any project requiring state-of-charge percentage from a LiPo/Li-Ion cell Package Contents 1× Adafruit LC709203F Battery Monitor Breakout 1× JST PH Jumper Cable Resources Adafruit LC709203F Guide Arduino LC709203F Library (GitHub) CircuitPython LC709203F Library (GitHub)
