Our core competitiveness lies in our top-tier R&D team: 5 senior technical engineers together with a CTO with 16 years of original Renesas chip development experience. We master independent development of underlying programs for lithium battery protection chips, different from competitors who only purchase finished chips externally. All product lines adopt premium cells from Samsung, LG, ATL and other top brands, equipped with genuine Renesas 045A20 protection ICs. Supported by over 100 self-owned plastic molds and automated production equipment, we have formed a closed industrial chain covering cells, protection boards, housings, assembly machines and charging adapters.

Adhering to the talent-oriented and integrity-based business philosophy, we stick to high-standard quality control and full-cycle after-sales service, flexibly accepting customized orders of small, medium and large batches. Relying on reliable products, transparent cooperation policies and long-term performance credibility, Weijie has built stable partnerships with hundreds of equipment manufacturers and traders at home and abroad, striving to be a trusted long-term comprehensive intelligent battery solution partner for global clients.
