Advanced Manufacturing Process

Our OEM 12V lithium batteries undergo a comprehensive production process from cell preparation to final assembly:

1. Battery Cell Preparation and Selection

Cell Type: 3-4 3.7V lithium-ion cells (18650, 21700 cylindrical cells, or pouch/square aluminum shell cells) connected in series
Core Technology: Precision electrode sheet production with lithium iron phosphate/ternary materials
Cell Assembly: Advanced winding/laminating methods with electrolyte injection and casing sealing
Quality Control: Rigorous activation and capacity separation testing to ensure cell consistency

2. Battery Pack Integration

BMS: Comprehensive protection system including overcharge/overdischarge/overcurrent/short-circuit protection
Wiring: High-quality wiring with appropriate cross-sectional area (≥10mm² for 160AH applications)
Enclosure: Durable sheet metal shell with IP54 waterproof rating and anti-corrosion coating

3. Testing and Quality Assurance

Performance Testing: ≥500 charge/discharge cycles with 80% capacity retention
Safety Tests: Short-circuit, compression (1000N pressure), and drop (1.5m height) testing
Environmental Testing: -20℃ to 60℃ temperature range verification
