High-Performance Backup Power Solution
The U300/U400/U500 614V 85Ah Lithium Battery Cabinet delivers robust DC backup power for medium to large UPS systems. Built with premium LiFePO4 prismatic cells, it offers long cycle life, high C-rate discharge capability, and fast charging. Advanced safety features — including excellent thermal stability, three-level BMS protection, and prismatic hard-shell design — greatly reduce thermal runaway risk, providing a safe, reliable, and eco-friendly solution for data centers and mission-critical applications.
Space-Saving & Modular Design
Its compact rack-mountable form factor optimizes server cabinet space. A single cabinet supports up to 12 modules and delivers up to 540 kW discharging power. The modular architecture allows 8–12 modules per rack and parallel connection of up to 8 cabinets, enabling flexible backup times from 5 to 30 minutes depending on load. Wide DC voltage compatibility ensures seamless integration with both high- and low-voltage UPS platforms.
Intelligent BMS and Full Customization
Each cabinet features an advanced multi-level BMS with real-time monitoring, diagnostics, and active cell balancing. Comprehensive communication interfaces (CAN, RS485, RS232, USB, Modbus TCP/IP) enable easy integration with most UPS and energy management systems. Dual-redundancy design plus intelligent charging logic maximizes reliability. Additionally, OEM/ODM services allow full customization of module configuration, cabinet quantity, voltage range, and remote monitoring to perfectly match your specific UPS requirements.
