Five Core Advantages (5 “O” Highlights)

Safer

The system uses cobalt-free LiFePO₄ (Lithium Iron Phosphate) battery technology, fundamentally eliminating the thermal runaway risks associated with cobalt-based lithium batteries.
LiFePO₄ chemistry offers higher safety, longer lifespan, higher efficiency, and higher power density, supported by an intelligent Battery Management System (BMS) for comprehensive protection.
