Overview

Every battery-powered robot depends on wiring that can handle sustained high-current discharge, regenerative braking surges, and the thermal cycling inherent to lithium-ion chemistry — without a single point of failure. Our battery pack wiring harnesses are purpose-engineered for robotic applications where downtime means lost revenue: AGVs running 20-hour warehouse shifts, autonomous cleaning machines operating in wet environments, and mobile manipulation platforms carrying 48V to 800V battery systems. We design complete battery interconnect solutions covering cell-to-cell busbars, BMS sense wire harnesses, high-voltage distribution cables, pre-charge circuits, and charging port assemblies. Every harness ships 100% hi-pot tested to 2× operating voltage and thermally validated across the full -40°C to +85°C service range. From 5-unit engineering builds to 10,000+ monthly production runs, our battery wiring harnesses meet UN 38.3 transport safety requirements and integrate seamlessly with CATL, BYD, Samsung SDI, and LG Energy Solution cell formats.

Buyer Questions Before RFQ

What should we send to get an accurate quote?

Send your drawing, BOM, quantity forecast, application environment, and any required approvals. Missing inputs create avoidable assumptions in pricing and lead time.

Will your team review the design before production?

Yes. Engineering review happens before quotation so connector, flex-life, shielding, and routing risks are flagged before you commit.

Can you support prototype through volume release?

Yes. We support first samples, validation builds, and production ramp with traceability and test requirements kept aligned.
