Single-cell fuel gauge with I²C
This is a single-cell battery monitor — the ModelGauge algorithm tracks state-of-charge using coulomb counting and voltage-based correction, reporting over an I²C interface. The 1-cell rating means it is designed for a single lithium-ion or LiFePO4 cell stack; it will not handle series packs without an external balancing circuit.
