BMS Battery Balance Parallel Cable VH3.96 3Pin Connector Harness

We have rich experience in optimizing compact and anti-vibration wiring structures, and can independently develop and produce high-qualitycustom wiring harness that meet customers’ unique equipment assembly and working environment requirements. All products strictly comply with RoHS industrial environmental protection standards, with stable and consistent batch quality, winning long-term recognition from global new energy and automotive supporting customers.

This BMS Battery Balance Parallel Cable VH3.96 3Pin Connector Harness is a miniaturized high-stability connecting harness tailored for new energy battery balance systems. Different from ordinary universal connecting wires with simple protection on the market, this product adopts symmetrical dual-terminal VH3.96 locking connector design, specially used for parallel signal and current transmission between battery equalization control boards. It abandons messy bare wire wiring methods, and integrates professional wire bundling, identification labeling and anti-wear protection structures. Although it is mainly oriented to new energy storage equipment, its rigorous industrial-grade production standards are consistent with high-end automotive wiring harness manufacturing specifications, with excellent anti-vibration, anti-aging and stable conduction performance.

In terms of structural design and material configuration, this harness uses high-quality UL1015 18AWG tinned copper conductors, matched with multi-color standardized insulation layering to ensure clear circuit distinction and convenient later maintenance. The outer part is equipped with a dedicated spiral protective tube, which effectively buffers friction and impact caused by equipment operation vibration and avoids wire skin damage and circuit failure. The double-ended VH3.96 locking connector can form a firm and stable plug-in structure to prevent virtual connection and disconnection in long-term working state. According to different BMS module sizes and installation space requirements, we can flexibly adjust wire length, wiring specifications and terminal matching forms to create exclusive custom wire harness assembly for different energy storage and battery balancing equipment.

In terms of quality control, every finished harness undergoes DC 500V high voltage withstand test, full conduction detection and terminal tensile test one by one before leaving the factory. It effectively eliminates potential problems such as poor conduction, short circuit and terminal looseness. The product supports a wide working temperature range from -40℃ to +105℃, and can maintain stable electrical performance in high-temperature, low-temperature and long-term vibrating equipment operating environments. The integrated heat-shrinkable marking label realizes quick circuit identification, greatly improving the efficiency of product assembly and equipment maintenance.

This battery balance parallel harness features compact structure, strong compatibility and high safety, and is widely suitable for internal connection of lithium battery pack equalization boards, signal parallel wiring of battery management systems, and internal matching wiring of small and medium-sized energy storage equipment. As a typical refined customized product of our company, it inherits the reliable quality advantages of our custom wiring harness series. While meeting the standard wiring needs of new energy equipment, its industrial-grade reliability also supports partial special vehicle battery module transformation and matching, expanding the application boundary of traditionalautomotive wiring harness. With flexible customization capabilities, our team can always provide one-stop custom wire harness assembly solutions according to customers’ personalized structural and performance indicators.
