QS12-S Connector Cable 250A High Current Anti-ignition Battery Plug Wire

The core innovation of QS12-S lies in its built-in pre-charge anti-ignition circuit structure. During plug-in docking, the small pre-charge contact connects first to slowly charge the equipment capacitance, eliminating instantaneous high-current arc sparks that easily burn battery terminals and pose fire risks. Molded physical reverse insertion prevention ribs completely block positive-negative reversed wiring to avoid short-circuit damage to lithium battery cells and power drive boards. The outer anti-slip ergonomic shell enables single-hand quick plug/unplug, with internal buckle locking to resist pull-off caused by vehicle bumping and cable tension.

All cable terminals adopt high-pressure crimp + hot melt double sealing reinforcement, eliminating hidden dangers of wire core shedding and water intrusion at wiring transition points. Multi-layer stranded ultra-flexible wire conductors withstand thousands of bending cycles without core breakage, adapting to frequent disassembly and mobile equipment wiring environments. Every finished harness undergoes strict full factory testing before shipment, including long-time 250A load temperature rise test, insulation withstand voltage test, vibration aging screening and plug life cycle test. We supply single-ended plug short cables, male-female extension harnesses and conversion wiring matched with terminal blocks and aviation plugs for energy storage manufacturers, electric vehicle modification factories and industrial heavy-duty power equipment suppliers.

Advantages

• Built-in pre-charge anti-ignition safety design: Pre-charge contact acts first during docking to buffer instantaneous high current, completely eliminate arc sparking when connecting large-capacity lithium batteries, effectively protect battery poles and extend lithium pack service life, greatly reducing fire safety risks of high-power equipment.

• 250A stable heavy-load low-heat transmission solution: Thickened full-gold plated large-diameter contact cores with ultra-low contact resistance, no obvious temperature rise under long-term full 250A operation, avoiding terminal melting and cable burnout faults common in inferior high-current connectors.

• High-temperature flame retardant fiber-reinforced PA housing: Superior heat deformation resistance compared to ordinary nylon materials, does not soften or deform under long-time high-current heat accumulation; UL94 V-0 flame retardant performance prevents flame spread in case of circuit short-circuit accidents.

• Dual power + optional signal integrated layout: 2 main poles undertake high-power charge-discharge loops, the reserved 4 auxiliary signal pins transmit BMS battery temperature, balance and communication signals simultaneously, realizing one-line integration of power and monitoring without separate signal wiring.

• Ergonomic one-hand quick lock anti-drop structure: Outer anti-slip textured shell for easy gripping during plugging; internal integrated snap buckle provides strong locking force to prevent accidental separation caused by vehicle vibration, traction and bumping.

• Full-scenario flexible OEM customization support: Support wire length ranging from 0.2m to 15m, upgrade thicker 2AWG wire for higher surge current demand, switch oil-resistant TPE wire for marine and construction machinery, small-batch prototype sample orders available for energy storage and new energy equipment development verification.
