This is an estimate, not a certification. Results are based on published degradation models (exponential decay with Arrhenius temperature correction) and typical operating profiles. Actual degradation depends on cell quality, BMS configuration, depth of discharge, thermal management, and operating history. For verified performance data, request a EnergyPassport certification.
