Instead of guessing remaining capacity from a non-linear voltage curve, this smart sensor does the maths for you — delivering a reliable percentage readout just like the battery indicator on your phone.\n\nCommunicating over I2C, the MAX17048 works with any microcontroller or microcomputer from Arduino to Raspberry Pi. It runs happily on both 3.3V and 5.0V power and logic, so there's no need to worry about level shifting.\n\nKey Features\n\n\nAccurate Fuel Gauging – Reports battery voltage and remaining charge percentage via I2C\n\nWide Compatibility – Works with 3.3V and 5.0V logic and power supplies\n\nSTEMMA QT / Qwiic Interface – Solderless I2C connections via JST SH connectors on both sides\n\nDual JST 2-PH Battery Ports – Connect your LiPo/LiIon battery to either port\n\nConfigurable Alerts – Set low-battery and other threshold alerts to suit your application\n\nLow Power Modes – Built-in power management options for battery-conscious designs\n\n\nIdeal For\n\nBattery-powered IoT projects requiring accurate charge monitoring\nPortable electronics with battery percentage displays\nFeather and microcontroller projects with LiPo batteries\nAny project where knowing remaining battery life is critical\n\n\nPackage Contents\n\n1× Adafruit MAX17048 Fuel Gauge breakout board\n1× JST PH jumper cable\n\n\n\nNote: STEMMA QT cable is not included. A 1S (3.7–4.2V) LiPoly or LiIon battery is required and sold separately.\n\n\nResources\n\nArduino Library (GitHub)\nCircuitPython/Python Library (GitHub)\nWhat is STEMMA QT?
