Custom battery packs validated before shipment.
We build a defined QC route for each OEM battery pack: incoming cell checks, BMS verification, process inspection, aging, final electrical test, packaging review, and traceable release records.
From approved cells to released cartons
The workflow below is the standard control route. Extra tests can be added for medical, marine, UAV, robotics, energy storage, low-temperature, or high-discharge battery projects.
Cell IQC
Model, batch, voltage, internal resistance, appearance, supplier documents.
Cell Matching
Group cells by electrical consistency before welding and module assembly.
Assembly IPQC
Welding, polarity, soldering, insulation, wire routing, connector placement.
BMS Verify
Charge, discharge, short-circuit, temperature, communication, balancing logic.
Aging & FQC
Capacity, load, voltage window, protection triggers, appearance release check.
Pack & Ship
Labels, carton marks, accessories, documents, batch record, shipment photos.

Reliable Battery Quality Control From Cell Selection to Final Delivery
Every custom battery pack undergoes strict inspection and testing throughout the manufacturing process. We verify electrical performance, safety protection, structural reliability, and production traceability before shipment.
Manufacturing QC Route
Cell Incoming Inspection
IQCEach battery cell is tested for voltage, internal resistance and capacity consistency before production.
- Voltage detection
- Internal resistance test
- Capacity screening
Battery Performance Testing
EOLFinished battery packs are tested for charging, discharging, capacity, and protection functions.
- Charge test
- Discharge test
- Capacity verification
Safety Protection Testing
BMSProtection systems are verified to ensure safe operation under abnormal conditions.
- Overcharge protection
- Over-discharge protection
- Short circuit protection
- Temperature protection
Production Traceability
BATCHEvery battery pack is linked with production records, testing data and material information.
- Batch number
- BOM record
- Test report
- Shipment record
Standards support for global battery sourcing
Certification needs vary by application, chemistry, destination market, and end product. We prepare the battery pack, documents, samples, and test data around the required path.
Transport test summary support for lithium battery shipping.
Portable sealed secondary lithium battery safety reference.
Industrial secondary lithium cell and battery safety reference.
Household and commercial battery safety evaluation path.
