125kW 261kWh Compact Commercial Liquid Cooled Energy Storage Cabinet
The BSLBATT LC125-261 is a compact 125kW/261kWh all-in-one commercial liquid-cooled battery energy storage cabinet. With a footprint under 2 square meters and low-noise operation, it fits commercial and industrial sites from retail centers to factories. Built with 314Ah LiFePO4 cells and pack-level liquid cooling for over 8,000 cycles, the integrated PCS supports peak shaving, demand management, and renewable energy self-consumption. Up to 8 units can be paralleled for flexible capacity expansion.
Full C&I BESS in a Single Compact Cabinet
All-in-one integration. 5 liquid-cooled LiFePO4 battery packs, 125kW PCS, BMS, EMS, and gas fire suppression, pre-assembled and factory-tested. One delivery, one connection, one day to commission.
Small footprint, low profile. The full system sits within 0.93 x 1.30m and weighs 2,260kg. That is roughly the floor space of a single pallet, making it practical for rooftops, basements, parking structures, and tight side yards.
Quiet enough for occupied spaces. Liquid cooling eliminates the high-speed fans found in air-cooled alternatives, significantly reducing acoustic output. Install next to offices, retail floors, or hotel lobbies without noise complaints.
Built for the long haul. IP55 outdoor rating, -20°C to 55°C operating range, 8,000+ cycle life, and a 10-year warranty. RS485, Ethernet, and Modbus RTU/TCP for remote monitoring and EMS integration.
