OEM/ODM Battery Manufacturing & Private Label Solutions
Skip years of R&D and millions in tooling overhead. Partner directly with DF Summit to manufacture custom LiFePO4 battery cabinets, modular rack systems, and commercial BESS under your brand—complete with custom BMS firmware, tailored enclosures, and international shipping certifications.
Custom Battery Pack Manufacturing Capabilities
From individual Grade-A 314Ah prismatic cells to fully integrated high-voltage battery cabinets, our factory offers comprehensive contract manufacturing with flexible MOQs.
Cell Grading & Precision Sorting
100% automated testing of internal resistance (IR), capacity (Ah), and open-circuit voltage (OCV) to ensure cell consistency and maximize battery pack cycle life (≥ 6,000 cycles).
Automated Laser Busbar Welding
High-precision robotic fiber laser welding of solid copper busbars ensures ultra-low contact resistance, zero cold solder joints, and structural resistance to heavy mechanical vibration.
BMS Hardware & Firmware Flashing
Custom Battery Management System architecture supporting dual CAN/RS485 communication protocols, custom baud rates, and pre-flashed profiles for Deye, Growatt, Victron, Solis, and more.
Sheet Metal & Enclosure Fabrication
CNC precision bending, laser cutting, and robotic powder coating for indoor (IP20) and outdoor (IP54/IP65) cabinets, wall-mount enclosures, and modular stackable rack chassis.
Active/Passive Thermal Engineering
Aero-grade aluminum heat sink designs, forced-air ventilation ducting, or integrated industrial HVAC air-conditioning systems ensuring safe operation between -20°C and +55°C.
100% Full-Cycle QC & Burn-In Testing
Every completed battery pack undergoes multi-cycle 0.5C charge/discharge aging tests, high-voltage insulation tests, and full BMS trip simulation prior to container loading.
