Cell Matching & Quality Control

QC ProcessStandard
Capacity gradingAll 80 cells matched within ±10mAh
Internal resistanceAll cells matched within ±5mΩ
Voltage matchingAll cells pre-charged to same voltage ±5mV
Formation cyclingEach cell cycled before assembly
Pack capacity test100% discharge test before shipment
BMS balance checkPack balanced to <5mV string delta

🔬 80-cell packs require rigorous cell matching — unmatched cells accelerate degradation and reduce cycle life. Our in-house grading process ensures maximum pack longevity.
