What are the critical performance specifications that should be standardized in bulk LiFePO4 battery orders for solar projects?

When placing bulk orders for LiFePO4 solar batteries, these specifications must be standardized:Capacity Tolerance: Typically +0%/-2% to ensure consistent energy storage across modules.Cycle Life: Minimum cycles at specified Depth of Discharge (e.g., >6,000 cycles at 80% DoD).Round-Trip Efficiency: ≥94% at nominal C-rates to optimize Levelized Cost of Storage (LCOS).Current Limits: Defined continuous and peak discharge...
