Quality Control Process
Incoming Material Inspection
Battery cells, PCM boards, flex cables and connectors are checked for appearance, dimensions, voltage and production consistency before assembly.
Cell Grading
Cells are grouped according to measured capacity, voltage, internal resistance, thickness, appearance and self-discharge performance.
Consistent cell grading helps reduce variation between batteries from the same production batch.
Capacity Verification
Professional battery analyzers are used to verify measured discharge capacity against the approved BM4Q product specification.
Capacity data should be reviewed during sample approval, especially because the ESC replacement capacity differs from the original device’s published typical capacity.
PCM Protection Testing
The PCM board is tested for overcharge, over-discharge and short-circuit protection according to the approved production procedure.
Flex and Connector Inspection
The flex cable, welding points, connector position and contact surfaces are checked for alignment, appearance and electrical continuity.
Charging and Discharging Test
Charging and discharging performance is checked to identify abnormal current, unstable voltage, excessive temperature or early capacity loss.
Aging Inspection
Aging tests help identify abnormal self-discharge and unstable electrical performance before shipment.
Final Inspection
Battery appearance, dimensions, BM4Q reference, flex position, printed information, quantities and packaging are checked before order release.
OEM and Private Label Service
