While Lithium Iron Phosphate (LiFePO4) chemistry offers exceptional cycle life and thermal stability, it possesses one critical electrochemical vulnerability: an absolute intolerance to charging at or below freezing temperatures (0°C / 32°F). While discharging remains chemically viable down to -20°C (-4°F) with moderate capacity derating, forcing charge current into frozen cells induces catastrophic, irreversible lithium … Read more
