Empower Industrial Operations with LC250-522 System

Built around dual 261kWh LiFePO4 battery clusters and intelligent liquid cooling, the BSLBATT LC250-522 integrates power conversion, thermal management, and safety protection into one cabinet. Supporting up to four parallel units for megawatt scale expansion, the LC250-522 specifications provide reliable energy storage for demanding industrial applications.

 

Dual Cluster Design

Equipped with dual 261kWh LiFePO4 battery clusters totaling 522kWh capacity, the system optimizes charge and discharge balancing while isolating cluster faults to maintain continuous operation.

Liquid Cooling System

Intelligent liquid cooling regulates cell temperature uniformity across all battery modules, reducing auxiliary power consumption and extending battery cycle life under heavy daily cycling.

Scalable MW Capacity

Supports parallel connection of up to four LC250-522 cabinets, allowing commercial and industrial operators to scale total storage capacity from 522kWh up to 2.088MWh as load demands grow.

All In One Integration

Combines battery racks, power conversion, thermal control, and fire suppression inside a compact industrial enclosure, significantly shortening on site installation and commissioning time.

High Power Output

Delivers 250kW rated power output to handle high load fluctuations in factories, logistics hubs, and mining facilities, effectively reducing peak demand charges and utility energy costs.

Multi Scene Operation

Engineered for peak shaving, demand management, backup power, and large scale solar integration, ensuring seamless grid interaction and stable energy supply for critical industrial loads.
