• Pulse Discharge Current (Short): 2.5C for 60 seconds at SOC > 40%
• Temperature Range (Discharging): -20°C - 60°C

Cycle Life and Safety:

• Cycle Life: ≥ 80% capacity retention after 2000 cycles at 1.0C charge/discharge.
• Self-Discharge Rate: ≤ 3.5% per month (at 25°C).

Additional Notes:

• Cells may have minor marks or cosmetic imperfections from transit; performance is unaffected.
• Datasheet available on request.
• Example configuration: Connecting 2 cells in parallel provides 50Ah; 15 cells in series delivers 2.4kWh at 48V nominal, ideal for energy storage systems (ESS)
