Clean-Room Facility
A dust-controlled assembly hall where cells are handled and packs are built.
Automated Assembly
Automated lines keep welding and assembly consistent from pack to pack.
Precision Calibration
Instrumented benches for BMS setup, measurement and calibration.
Production lifecycle
Our systematic approach ensures every battery pack exceeds industrial aviation standards through multi-stage fabrication.
1
Cell Preparation
Precision matching
Incoming cells are graded and matched into consistent groups before assembly.
2
Pack Assembly
Automated spot welding
Matched cells are joined into packs on automated spot-welding lines.
3
BMS Integration
Smart monitoring config
The BMS is installed and configured for monitoring, protection and communication.
4
Final Assembly
Enclosure & connectors
Packs are sealed in their enclosure and fitted with your specified connectors.
Zero-defect philosophy
Quality validation
Every battery pack passes four checkpoints, from incoming cell inspection to final certification, before it leaves our factory.
100%
Of packs fully tested before they ship
50+
Test parameters checked during validation
Incoming Inspection
Rigorous cell grading and chemical analysis before entering assembly.
Voltage & Capacity
Full-load performance verification to ensure specified energy density.
Aging & Cycle Testing
Accelerated life testing ensuring long-term stability and reliability.
Final Inspection
Comprehensive safety and compliance checks before final certification.
