Manufacture Expertise
One Factory, Six Main Controlled Process Steps
Our Huizhou factory is equipped with full-process battery pack manufacturing equipment, from automatic cell sorting and welding to BMS assembly, pack assembly, aging and reliability testing. Each production step is controlled to keep capacity, internal resistance and safety performance consistent.
—— STEP 01
Cell Sorting & Matching
Cells are automatically sorted and matched by internal resistance, voltage and capacity before assembly.
—— STEP 02
Automatic Welding
Full automatic welding equipment forms low-resistance, consistent connections between matched cells.
—— STEP 03
BMS Assembly
Protection board (BMS) production and installation, with balancing and temperature protection verified.
—— STEP 04
Pack Assembly
Finished packs are assembled with custom housings, connectors and insulation for OEM and ODM orders.
—— STEP 05
Aging Tests
Every pack goes through aging to confirm stable capacity, internal resistance and protection performance.
—— STEP 06
Finished-Pack Testing
Finished-pack testing before packing and shipment supports safety and reliability for global markets.
Our commitment to quality and dependable customer service sets us apart from the competition.
