QS12-S Male Female Large Current Anti Spark Connector Model Aircraft Lithium Battery Plug

QS12-S Male Female Large Current Anti Spark Connector Model Aircraft Lithium Battery Plug

The QS12 series is a two-pole ultra-high current anti-spark power connector, equipped with built-in pre-charge auxiliary pins, thick full gold-plated copper terminals, supporting continuous 240A and instantaneous peak 360A discharge. It is specially developed for large agricultural spraying drones, heavy-lift cargo multi-rotor UAVs, high-power outdoor energy storage power stations, large electric vehicles and industrial mobile lithium battery packs. The built-in anti-spark pre-contact pin eliminates electric arc sparks during live plugging/unplugging of high-capacity lithium batteries, greatly reducing fire risks in field equipment maintenance. The dual-color high-strength PA66 flame retardant housing comes with an integrated silicone waterproof dustproof sealing ring, adapting to harsh outdoor working environments such as farmland dust, rain splash and high-temperature engine compartments. Large-diameter gold-plated conductive poles minimize contact resistance and heat accumulation, effectively avoiding plug melting and thermal runaway under full-load heavy discharge. It adopts rear wire crimping/soldering structure, compatible with 6AWG / 8AWG ultra-thick high-temperature silicone wire. Fully RoHS compliant, widely used for 10L~40L agricultural spray drones, portable off-grid energy storage power supplies and large RC industrial model aircraft lithium power connection.

QS12-S Male Connector QS12-S Female Connector Large Current Connector Anti Spark Connector Model Aircraft Connector Lithium Battery Connector

Product Description

Built-in anti-spark pre-charge pin solves the major safety hazard of open sparks during live battery replacement of large agricultural drones, effectively avoiding lithium battery ignition accidents in farmland high-dust environments. Oversized thick gold-plated copper poles far exceed the current capacity of QS9/XT150 plugs, meeting the full-throttle peak power demand of 30L+ heavy-lift spray UAVs, with low temperature rise and no melting failure under long-hour continuous discharge. Integrated silicone sealing ring forms splash-proof and dustproof protection, adapting to outdoor rain, crop dust and fertilizer mist working conditions that ordinary un-sealed plugs cannot withstand. Dual-color split shell with anti-reverse bump double protection eliminates short-circuit burnout caused by misplugging during field assembly and maintenance. The large rear wire cavity is compatible with ultra-thick 6AWG high-power silicone wire, matching large-capacity high-discharge lithium battery main power wiring layout.

Every QS12 connector passes strict factory safety testing before shipment, including 240A long-time load temperature rise test, anti-spark arc suppression test, 48h neutral salt fog anti-corrosion screening and waterproof splash test. We supply single male/female bare plugs and finished thick silicone wire adapter cables for agricultural UAV manufacturers, outdoor energy storage equipment brands and industrial large RC aircraft R&D teams.

FAQ

Q1: What is the difference between QS12 and QS9 anti-spark connectors?

A: QS12 adopts oversized conductive terminals, supporting continuous 240A (QS9 only 180A); QS12 has built-in silicone waterproof dust sealing ring, suitable for outdoor farm harsh environments, while QS9 is mostly PCB internal board-mounted without waterproof function.

Q2: Can QS12 completely eliminate sparks when plugging lithium batteries live?

A: Yes, the built-in pre-charge auxiliary pins contact first to buffer instantaneous high surge current, no obvious electric arc spark appears during live plug/unplug of large lithium packs, greatly reducing fire risk.

Q3: What thickness wire can be matched with QS12 plug?

A: It supports 6AWG and 8AWG ultra-thick high-temperature silicone heavy current wire, which can bear ultra-high discharge current of large spray drones and energy storage power stations.

Q4: Is QS12 suitable for outdoor farmland rainy and dusty working conditions?

A: The built-in orange silicone sealing ring forms IP54 dustproof and splash-proof protection, which can resist short-term rain splashing and crop dust accumulation during farmland operation.

Q5: Can we customize finished extension cables with QS12 plugs on both ends?

A: Fully supported, we can assemble arbitrary length adapter cables with 6/8AWG silicone wire for battery parallel charging and power distribution use.
