About CALB
CALB Group is a Hong Kong-listed Chinese battery manufacturer headquartered in Changzhou that produces its own LFP prismatic cells (314 Ah Gen 2.0 in mass production; 392 Ah, 588 Ah, 640/661 Ah and 684 Ah announced) and integrates them into stationary storage systems. The published utility-scale line consists of a 20ft 5 MWh high-voltage liquid-cooled container built on 314 Ah cells in 1P104S packs, a second-generation 20ft '6.25 MWh+' liquid-cooled container shown with CE certification in 2025 and re-presented as the ZHIJIU 2nd generation in 2026, an overseas-version 314 Ah 20ft ISO container, plus 20ft 6.9 MWh and 10ft '10 MWh+' modular systems announced at EES Europe 2026. For C&I the company lists 373 kWh HV and 261 kWh LV liquid-cooled outdoor cabinets and a 418 kWh cabinet. All systems use liquid cooling; pack-level fire detection/suppression and IP67 packs are claimed. What CALB does not publish: there are no downloadable datasheets on the English or Chinese sites, so rated power, DC voltage windows, dimensions, weights, operating temperature, warranty and exact certification lists (only 'UL', 'IEC', 'CE' are named) are not available; the English site shows only reference projects, and the product brochure download returns 403.
