We support OEM/ODM customization of voltage, capacity, dimensions, structure and BMS functions, with fast prototyping, volume production and full export certification support. Our products are certified to UN38.3, IEC62133, GB31241, RoHS and CE, and are exported to customers worldwide.
Jindunxin Energy founded in Shenzhen, focusing on lithium cells and battery packs.
Hardware and BMS R&D teams formed with complete pack design capability.
Thermal pad and gel lines started, forming a dual business of cells and materials.
Products certified to UN38.3, IEC62133 and CE; export business grew rapidly.
Automatic sorting, welding and aging lines added, doubling pack capacity.
Products exported to 30+ countries, expanding in energy storage and medical sectors.
Core R&D team of hardware, BMS, structural and process engineers (desensitized)
Our R&D center is composed of battery hardware engineers, BMS software engineers, structural engineers and process engineers, with core members having over ten years of experience in the lithium battery industry.
The team covers the full development chain from cell selection, protection board design and structural tooling to reliability validation, delivering complete solutions including thermal design, BMS architecture and safety redundancy.
The center is equipped with charge/discharge test cabinets, internal resistance testers, thermal chambers, vibration tables and crush/nail penetration safety test equipment.
Production lines, test equipment and safety test scenes
Our modern production workshop is equipped with automatic sorting, spot welding, assembly, aging and packaging lines, supporting both small trial runs and volume supply.
The laboratory provides complete battery safety and performance testing: charge/discharge cycling, overcharge and over-discharge, short circuit, crush and nail penetration, vibration and drop, and thermal testing.
Full-process IQC, IPQC and OQC inspections are carried out, and key process data is traceable.
