Adafruit Coulomb Counter LTC4150 Breakout - AB170 buck converter this board uses high-quality componentsCoulomb Counter Breakout LTC4150 Battery Charge Tracker The LTC4150 Coulomb Counter Breakout precisely tracks how much charge (in coulombs) flows into and out of a battery, giving you an accurate picture of remaining battery capacity. Unlike simple voltage based fuel gauges, coulomb counting works reliably under varying load conditions making it the gold standard for battery state of charge estimation in portable projects.
