Description




The 628Ah LiFePO4 (Lithium Iron Phosphate) cell is an ultra-high capacity energy storage solution engineered 

for next-generation Battery Energy Storage Systems (BESS). Designed specifically for utility-scale and commercial & industrial (C&I) applications, 

this cell delivers exceptional energy density, ultra-low internal resistance, and an industry-leading cycle life of ≥12,000 cycles (80% DoD).


With a robust and compact design weighing only 11.3kg, this 628Ah prismatic cell reduces the total number of cells required per system, 

significantly lowering assembly complexity and overall system cost. Its ultra-low internal resistance of ~0.12mΩ ensures high efficiency 

and minimal heat generation during high-power operations.



Key Benefits

  • Ultra-High Capacity: 628Ah nominal capacity, maximizing energy storage per cell and reducing system integration costs.

  • Extreme Longevity: ≥12,000 cycles at 80% DoD, providing exceptional operational reliability and a lower Levelized Cost of Storage (LCOS).

  • Ultra-Low Internal Resistance: ~0.12mΩ, ensuring high round-trip efficiency, lower heat generation, and stable performance under high current.

  • Lightweight & Compact Design: Weighing only 11.3kg with a thickness of 72mm, it allows for more compact and space-efficient module designs.

  • Superior Safety: LFP chemistry guarantees high thermal stability and intrinsic safety, compliant with major international standards.

  • Maintenance-Free: Designed for long-term, maintenance-free operation in demanding grid and renewable energy environments.
