VH3.96 BMS Interconnect Cable

Fubang Wiring Harness, founded in 2013 and certified with IATF16949 quality management system, is a professional manufacturer focusing on automotive wiring harnesses, new energy battery connecting wires and industrial wiring solutions based in Shenzhen. We have rich experience in designing and manufacturing custom wire harness assembly, focusing on meeting diversified personalized wiring demands from energy storage, automotive electronics, industrial control and RV marine industries. Our independent workshop completes cutting, crimping, assembly and testing procedures in one stop, strictly executing RoHS environmental standards and full electrical inspection for all finished products. Besides standardized wiring harnesses, we also provide flexible design services for customized electrical connectors and finished cable products, supporting customers’ special size, pin definition and material customization requirements. With stable production capacity and rigorous quality control, we have built long-term cooperative relationships with numerous battery management system manufacturers and auto modification enterprises worldwide.

Our VH3.96 BMS Interconnect Cable is tailor-made for lithium battery equalization board internal connection scenarios, serving as short-distance signal jumper wiring between BMS modules. This cable adopts asymmetric 3Pin to 2Pin VH3.96 connector layout, perfectly matching the common port design of mainstream battery equalization boards.

For raw material configuration, we select premium UL1007 22AWG tinned copper wire as the conductor core, paired with industrial-grade PA66 lock-type connector shells. We offer mature custom cable assembly solutions for this product series: clients can freely adjust total length, wire gauge, connector pin sequence and heat shrink labeling content according to actual installation space.

Strict electrical performance control is implemented during production: each piece passes 100% continuity detection and DC300V withstand voltage testing, with maximum conduction resistance controlled below 2Ω and insulation resistance kept above 10MΩ, effectively avoiding short circuit and open circuit faults in long-term equipment operation. The built-in locking structure of the VH3.96 connector can prevent accidental disconnection caused by equipment vibration, adapting to complex working environments ranging from -40℃ to +105℃.

Different from long-distance heavy-current wiring harnesses, this interconnect cable focuses on compact internal signal transmission inside battery packs. We optimize the overall wire bending performance and appearance structure, add dual heat shrink protection for wiring transition sections, and retain standardized marking areas for convenient subsequent installation and maintenance. Combined with our advantages in customized electrical connectors, we can quickly revise connector matching specifications when customers upgrade equalization board ports; relying on mature custom wire harness assembly technology, we realize small-batch trial production and mass delivery efficiently; our comprehensive custom cable assembly service also covers special wire color, high-temperature wire replacement and special crimp terminal customization.
