CBAK Energy Reports Progress in Customer Testing of Full-Tab 26650 LFP Cells for AI Data Center Backup Power

CBAK Energy has advanced its 26650 LFP cell product line into customer validation phase, with samples of the HP V2.0 and PFS2 V2.0 variants currently under evaluation by multiple leading data center operators. This progression from development to real-world testing represents a critical commercialization milestone in the competitive energy storage and backup power segment.

The early feedback noting strong performance across key metrics—including energy density, cycle life, and thermal stability—suggests CBAK's LFP chemistry may address enterprise-grade reliability requirements for AI data center backup systems. Multiple customers advancing simultaneously to module-level validation indicates sufficient confidence to move beyond initial feasibility assessment, reducing time-to-market risk.

LFP (lithium iron phosphate) cells are favored in data center applications due to inherent safety, thermal stability, and lower cost relative to competing chemistries. The 26650 form factor targets mid-range capacity and power density needs, positioning CBAK within a growing segment as AI infrastructure buildout accelerates power resilience demands globally.

Sector implication: Success in data center backup power could expand CBAK's addressable market beyond automotive into higher-margin, mission-critical infrastructure—a structural tailwind for industrial battery suppliers amid energy transition. Validation progress reduces execution risk but remains early-stage; commercial volume deployment outcomes will drive valuation impact.
