-40℃ 12.8V 9.6Ah Low Temperature Battery Pack with CE & UN38.3 Certification
Outdoor electronics, defense equipment, and extreme-environment systems makers often have a hard time finding a power option that works in very cold temperatures and meets strict certification standards. For this project, the customer needed a small but strong 12.8V LiFePO4 battery pack that could reliably discharge at -40°C, have a high current flow for peak loads, and meet CE and UN38.3 transport standards.
CM Batteries developed a fully customized low-temperature LiFePO4 pack designed to outperform standard lithium batteries in cold weather environments and ensure long-term operational stability.
Key features：
- Ultra-low temperature operation down to –40°C：Ensures reliable startup and stable operation in extreme cold regions.
- High discharge current 50A for heavy-load devices: Burst current: 80A ≤ 500 ms.
- Full certification for global deployment: Certified to CE and UN38.3 standards, ensuring safe exportation and worldwide compliance.
- Long cycle life ≥1500 cycles: Optimized BMS and pack design deliver over 70% capacity retention after 1500 cycles.
- Wide storage temperature range: Supports stable storage for 3 months at –20°C to +35°C and 12 months at –20°C to +25°C.
