Narada begins global delivery of its 6.25 MWh liquid-cooled battery energy storage

Narada Power has announced the global availability of its Center L Ultra BESS, a 6.25 MWh liquid-cooled solution housed in a standard 20-foot container, that is designed for two- to eight-hour applications. 

The system supports multiple battery configurations, including 587 Ah and 783 Ah LFP cells, and an additional variant using 565 Ah / 752 Ah cells. The chief distinction between the two variants is the maximum charge and discharge rate, with the 587/783 Ah variety offering an up to 0.25C figure, while the 565/752 Ah is rated for up to 0.5C, enabling faster cycling. (In battery terms, 1C corresponds to charging or discharging the full capacity in one hour ie. 0.5C means a two-hour full cycle. Hence, flexible applications for the duration of storage.)

Both feature intelligent thermal management that maintains temperature differentials under 2.5 degrees Celsius, reducing auxiliary power consumption by 30 percent, according to Narada Power.

The system is pre-installed and pre-commissioned for rapid deployment and includes over-the-air (OTA) upgrade capabilities to remotely update software, and seismic resistance up to grade 8. 

Each container integrates a modular architecture with both AC and DC interfaces available, supporting voltage levels from 1,150 V to 1,500 V depending on the configuration. The system operates across a wide ambient temperature range of –30°C to +55°C and features IP55 protection with C5 anti-corrosion ratings, making it suitable for a variety of outdoor environments. Fire safety is addressed through aerosol and water mist suppression systems, alongside support for remote system diagnostics.

Cycle life for the LFP battery configurations is rated at over 8,000 cycles at 25°C with 80 percent depth of discharge, and round-trip efficiency is rated at 95.5% at cell level and 89% at system level, according to Narada. The control system includes PCS and BMS integration, local touchscreen HMI, and multiple communication protocols including Modbus TCP and IEC 61850.

No solid-state yet

Narada’s solid-state flagship, the Center L Max – featuring an 8.338 MWh AC/DC system and proprietary 783Ah battery cells – made its debut at ESIE 2025 in Beijing this past April. It is currently still in the pipeline with no confirmed release date. The new Center L Ultra BESS does not feature these cells.

The Center L Max’s 783Ah solid-state battery cell integrates three core technologies to address common interfacial challenges in solid-state designs. Its proprietary in-situ electrolyte film formation enables a conformal coating around active materials, reducing interfacial resistance and enhancing cycling performance.
