Technical Product Data Sheet (Batch/Model: 118f1)

The CHAM 32140 ESS-Grade Cell is a high-capacity, heavy-duty Lithium Iron Phosphate ($\text{LiFePO}_4$) cylindrical battery expertly developed by CHAM Battery, a manufacturer with decades of expertise in large-format cylindrical cells. Delivering a substantial 15Ah (15,000mAh) capacity at a 3.2V nominal voltage, this single 32140 cell supplies an impressive 48Wh of energy storage.

Purpose-built for stationary grid storage and demanding electric mobility applications, this ESS-grade (Energy Storage System) cell combines tight internal quality controls with low internal resistance. The resulting performance reduces structural complexity by eliminating the large number of smaller parallel cells needed for heavy-duty battery banks.

Core Product Highlights

• Massive Form-Factor Efficiency: The large 32140 architecture provides a spacious 15Ah unit capacity, significantly reducing total spot welds, interconnects, and assembly labor for larger pack designs.

• Industrial ESS Lifecycled Profile: Engineered for exceptional resilience in deep-cycling applications, easily surpassing 3,000+ complete charge/discharge cycles (at 80% DOD) before minimal capacity degradation occurs.

• Robust Transient Output: Boasts a powerful 2C continuous discharge rating (30A) and up to 6C peak pulse capability (90A) to comfortably handle severe electrical surges and motor acceleration demands.

• Inherent Structural Safety: Formulated with top-tier LFP chemistry to maintain an exceptionally high thermal threshold. The cell remains completely non-flammable and safe from combustion hazards, even when subjected to accidental overcharging or physical impacts.

• Flat Discharge Plateau: Delivers constant, unvarying voltage across nearly the entire discharge cycle, ensuring high-efficiency power delivery and eliminating machine performance drops.
