QS9 Male Female Connector Antispark Gold-Plated Terminal High Current Banana Head

QS9 Male Female Connector Antispark Gold-Plated Terminal High Current Banana Head

This QS9L series heavy-duty power connector is a two-pole high-current plug equipped with built-in anti-spark auxiliary signal pins, thick full gold-plated banana terminals, supporting continuous 180A / peak instantaneous 240A discharge. It is specially designed for large-capacity lithium battery packs, high-power FPV multi-rotor UAVs, RC off-road vehicles, portable outdoor energy storage power stations, electric skateboards and industrial high-current power conversion modules. The integrated anti-spark small contact pin realizes pre-contact current buffering during live plugging, eliminating electric arc sparks and greatly improving lithium battery operation safety. Thickened pure copper gold-plated conductive poles minimize loop resistance and heat accumulation, effectively avoiding melting and burnout under full-load heavy discharge. Black UL94 V-0 flame retardant PA66 plastic housing with integrated PCB soldering feet, convenient for direct welding on BMS mainboards and power distribution PCBs. Fully RoHS compliant, customizable wire solder terminal version, male/female matching sets and parallel power distribution assembly, widely used in large agricultural spraying drones, high-power RC models and outdoor camping energy storage equipment.

QS9 Male Connector QS9 Female Connector High Current Connector Gold-Plated Terminal Lithium Battery Adapter Banana Head Connector RC Model Car Accessories

Product Description

Built-in anti-spark auxiliary pin structure solves the safety hazard of open flame sparks when plugging high-capacity lithium batteries live, greatly reducing fire risk during field battery replacement for large UAVs and energy storage power stations. Extra-thick gold-plated copper poles with large contact area drastically reduce circuit resistance, effectively controlling temperature rise under 180A full continuous discharge, fundamentally avoiding the common failure of inferior high-current plugs melting and burning. Integrated PCB flat solder feet simplify lithium pack BMS board assembly process, no extra wire transfer needed, save internal battery space. Flame retardant PA66 housing meets strict fire safety standards of aerial lithium battery equipment; clear positive/negative embossed marks prevent reverse insertion short-circuit damage to expensive BMS chips and power equipment. Male/female self-locking tight fit structure will not separate under UAV flight vibration and RC model violent jolting, avoiding sudden power loss crash accidents.

Every QS9L connector passes strict factory high-current safety testing before shipment, including 180A long-hour temperature rise test, anti-spark arc suppression test, 48-hour salt fog anti-corrosion screening and PCB solder foot tensile retention test. We supply single male/female PCB plugs and matched thick silicone wire adapter cables for large agricultural UAV manufacturers, outdoor energy storage power station brands and high-power RC hobby factories.

FAQ

Q1: What is the function of the middle small auxiliary pins of QS9L plug?

A: They are anti-spark pre-charge pins. These tiny pins touch the circuit first when plugging, pre-charge the capacitance in the power system to buffer instantaneous high current, so no bright electric arc spark appears during live connection/disconnection of large lithium batteries.

Q2: What is the maximum continuous discharge current QS9L can safely bear?

A: Stable continuous working current 180A; short-time instantaneous peak discharge can reach 240A, fully meeting the full-throttle power demand of large agricultural UAVs and 6kW energy storage power stations.

Q3: Can this QS9L plug be directly soldered to the lithium BMS PCB board?

A: Yes, the bottom comes with integrated flat PCB solder pins, which can be directly inserted into the through holes of the protection board for automatic wave soldering, no extra wire transfer required.

Q4: What is the difference between QS9L and ordinary XT150 high-current plugs?

A: QS9L adds built-in anti-spark auxiliary pins to eliminate arc sparks, and uses thicker gold-plated copper poles with higher 180A continuous current rating; XT150 has no anti-spark function and lower current tolerance.

Q5: Can we customize the version with rear wire solder terminals instead of PCB pins?

A: Fully supported, we can produce QS9L male/female plugs with open rear solder cups, which can be soldered with 8AWG/10AWG thick silicone wire to make lithium battery extension adapter cables.
