Why Inconsistency Happens

Lithium iron phosphate (LiFePO₄) battery packs naturally face inconsistency challenges over time.

• Manufacturing differences: Even with strict process control, slight variations in materials and production steps lead to differences between cells.
• Usage environment: Temperature, ventilation, and charging/discharging conditions accelerate these differences during operation.
• Time factor: The longer a pack is in use, the greater the gap between individual cells, which can shorten overall battery life.

How to Detect Poor Consistency

1. Voltage deviation – Cells charged to the same SOC but showing different open-circuit voltages.

2. Internal resistance variation – Causes uneven heating and performance dispersion.

3. Capacity & lifespan gaps – Differences in available capacity directly affect pack longevity.

4. Temperature rise inconsistency – Unequal heat dissipation due to cell position and material variations.
