Professional Battery Wire Harness Manufacturing
OurPCB manufactures battery wire harnesses for electric vehicles, energy storage systems, and industrial power applications. Our battery cables handle high currents with low resistance connections for efficient power delivery and minimal losses.
For EV applications, we provide complete battery pack wiring including cell interconnects, module harnesses, and main high-voltage power cables. Our EV harnesses include proper safety features including HVIL circuits and orange jacket identification per automotive standards.
Our battery harnesses use properly sized conductors with fusion-welded or hydraulically crimped terminals for reliable, low-resistance connections. We work with Anderson Power and other premium connectors designed for high-current applications. Compact battery interfaces for cordless tools can also be built as power tool wire harnesses with trigger, motor, LED, and charger wiring in the same controlled assembly.
Whether you need industrial battery cables for forklifts and AGVs, or custom battery harnesses for specialty applications, our IATF 16949 certified manufacturing delivers reliable power distribution solutions.
From the Case Bank
A US marine OEM sought a new supplier for custom wire harnesses and audio systems, initiating a rigorous multi-month evaluation process involving multiple business units.
The customer issued 6 separate RFQs over two months and engaged in a 64-email deep-dive technical thread, demanding strict weekly delivery, tariff mitigation, and cost competitiveness compared to incumbent suppliers.
Maintained rapid response times (1-2 days), proactively proposed a buffer stock strategy (advance ordering) to meet weekly delivery needs and mitigate tariff risks, and transparently presented alternative material options with cost benefits.
Successfully navigated the extensive qualification process, secured the tooling order, and transitioned into the prototyping phase for mass production.

Battery Harness FAQ
Battery cable sizes depend on current requirements. Light-duty applications may use 8-4 AWG, while high-current EV or industrial applications often require 2 AWG to 4/0 AWG. We size cables based on continuous current, voltage drop requirements, and temperature rating.
Yes, we manufacture complete EV battery harnesses including cell interconnects, module cables, main power cables, and BMS (Battery Management System) wiring. Our high-voltage harnesses include proper safety features per automotive standards.
We offer various battery terminals including ring terminals, battery lugs, Anderson connectors, and custom terminals. For high-current applications, we use fusion-welded or hydraulically crimped connections for reliable, low-resistance joints.
Yes, we can integrate fuse holders, fusible links, or battery disconnect switches into battery harness assemblies. Proper overcurrent protection is essential for battery safety and we can recommend appropriate solutions for your application.
