Based on the MAX17048, the Qwiic Fuel Gauge is perfect for monitoring your single-cell LiPo. While the MAX17048 provides pack voltage, it really shines with its Statement of Charge (SOC). 3.83V is ok to know, but knowing your battery is at 73% capacity is considerably better.
This is not a 'take the LiPo voltage curve and hack it into little voltage pieces' type of IC. The MAX17048 has a sophisticated algorithm that constantly monitors the pack giving much more accurate readings than a simple ADC. We've also written a fully featured Arduino library making interfacing as easy as a lipo.getSOC() call away.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
