High-Current Battery Connector for Electric Motorcycles Officially Mass-Produced

April 29, 2026

After more than a year of dedicated efforts, our new product has successfully achieved mass production as a high-current battery charge/discharge connector specifically designed for electric motorcycles. This milestone was reached following the optimization of processes across R&D, mold making, assembly, and testing, as well as full certification by end customers. The connector meets stringent requirements including IP68 waterproofing and 600-hour salt spray testing.

Frequently Asked Questions

Guangyitong Precision is a technology-driven OEM manufacturer based in Shenzhen, China. We specialize in precision mold design & manufacturing, injection molding, CNC machining, and assembly services. With over 20 years of experience, we deliver Japan-quality precision parts to clients worldwide.

We serve automotive, consumer electronics, smart devices, EV / electric vehicles, office equipment, and industrial machinery sectors. Our team handles custom parts for both domestic and international clients with multi-language drawing support (CN / JP / EN).

Our CNC machining achieves tolerances as tight as 0.005mm, with standard precision parts held to 0.025mm. We handle 4-axis and 5-axis machining for complex geometries and tight-spec components.

Yes. We specialize in low-volume, high-mix production — including single-piece prototypes. Rapid prototyping is one of our strengths, with fast-turnaround sampling via SF Express, DHL, or UPS.

Absolutely. Our engineering team reads and processes technical drawings in Chinese, Japanese, and English. Just send us your drawings and we’ll take care of the rest.

We work with engineering plastics (ABS, PA, POM, PC, etc.), aluminum alloys, stainless steel, copper, and custom-spec materials. Please contact us to confirm availability for your specific requirements.

1. Send your drawing or sample → 2. We provide a quote within 24 hours → 3. Confirm order & tooling → 4. Prototype / mass production → 5. QC inspection → 6. Shipment. We keep you updated at every stage.

We follow Japanese quality management standards with strict incoming material inspection, in-process QC, and final inspection before shipment. Our mission: “Japan-quality products made in China.”

Tooling lead time is typically 15–30 working days depending on complexity. Sample production takes 3–7 days after tooling approval. Mass production timelines are confirmed at order placement.

We have no strict MOQ. We accommodate orders from a single prototype to large-scale production runs — this flexibility is one of the key reasons our clients trust us for both R&D and full production.

Reviews From Our Happy Clients
"Our product had an extremely complex structure, and several teams we reached out to declined the project. They not only took it on but also delivered an exceptionally professional design solution. The parting line and cooling system designs were perfectly engineered, and the final product met all our dimensional accuracy requirements. Working with them was truly hassle-free!"
"The attention to detail in their mold design is outstanding! From the runner system to the ejection mechanism, every aspect was meticulously considered. There was no need for repeated revisions or follow-ups, and we encountered absolutely no flash or shrinkage issues during production. The quality speaks for itself!"
"We had extremely strict tolerance requirements, and they kept up perfectly with our pace. The 3D drawings were exceptionally clear and detailed, with tight, precise tolerance control. The handover to production was completely seamless—this collaboration was a perfect 10/10 experience!"
