The flight reliability of model aircraft and drones relies fundamentally on the stable power output of lithium batteries. As the power hub connecting lithium batteries to ESCs and motors, connectors directly determine flight safety and equipment service life.During plugging and unplugging, high-frequency discharge, high-altitude vibration and other operating scenarios, lithium batteries for model aircraft and drones are prone to electric arcs (commonly known as "sparking") caused by sudden current changes.This not only ablates contacts and increases contact resistance, but in severe cases can also lead to potential safety hazards such as battery short circuits and fire risks.
Therefore, selecting the right manufacturer and brand is crucial when choosing dedicated connectors.Founded in 2002, Changzhou Amass Electronics Co., Ltd. (the original creator of the XT series) has 24 years of expertise in DC high-current connectors for low-voltage intelligent devices below automotive grade.As a specialized, sophisticated, innovative "Little Giant" enterprise and a national high-tech enterprise, we integrate design, R&D, manufacturing and sales.We hold more than 200 patents, have over 10,000 project cases, and have provided customers with a cumulative installed quantity exceeding 100 million units.
Located in Lijia Industrial Park, Wujin District, Jiangsu Province, the company boasts a 30,000+ square-meter production facility with independent land property rights, supported by a team of nearly 300 professionals in R&D, manufacturing and sales.
With over a hundred connector models, we fully meet the application demands for garden tools, energy storage equipment, electric vehicles, smart home appliances, intelligent robots, model aircraft and drones.We also provide efficient product development and production services, offering 7A full-cycle solutions for industrial customers.
AMASP anti-sparking connectors, featuring a built-in arc-extinguishing structure and highly reliable design, precisely solve the connection pain points of lithium batteries for model aircraft and drones, providing safe and efficient connection solutions for scenarios such as model flight and drone inspection.
Core arc-suppression technology eliminates sparking hazards at the source.During the hot-plugging of lithium batteries for model aircraft and drones, internal capacitors charge instantaneously, causing sudden current surges. Especially when high-rate lithium batteries disconnect under loads above 50A, energy released from residual inductance between contacts forms a high-temperature plasma channel, creating visible electric arcs.Over time, this leads to contact oxidation and ablation, and even damage to the lithium battery protection circuit.
Featuring the synergistic effect of ceramic capacitors and manganin resistors, AMASS anti-sparking connectors reduce arc duration from 3.2ms (conventional connectors) to just 0.4ms, and suppress voltage spikes within safe thresholds.By physically blocking the energy path that generates arcs, we thoroughly solve the problem of sparking during plug-in and disconnection.
High current-carrying capacity and low loss meet the high-frequency discharge requirements of lithium batteries.During takeoff, acceleration and hovering of model aircraft and drones, lithium batteries need to deliver instantaneous high current.Excessively high contact resistance in traditional connectors increases power loss and excessive contact temperature rise, affecting flight endurance and equipment stability.
Featuring an automotive-grade crown spring contact structure, combined with 1.2μm thick gold-plated contacts and a nickel underlayer, AMASS anti-sparking connectors achieve a contact resistance of ≤0.8mΩ and a rated current of 12–60A.They easily adapt to the high-rate discharge demands of model aircraft and drone lithium batteries, with power transmission loss below 2%.At the same time, they effectively control contact temperature rise and avoid connection failure caused by overheating.
Anti-vibration and anti-disengagement design adapts to complex high-altitude flight conditions.Continuous high-frequency vibration during model aircraft and drone operation can easily cause traditional connectors to loosen or make poor contact, resulting in power interruption and crash risks.
AMASS anti-sparking connectors adopt a reinforced side latch structure for secure locking, meeting high pull-out force requirements.They effectively resist high-frequency vibration and turbulence during high-altitude flight, ensuring stable connection between lithium batteries and equipment at all times.
Featuring a compact structure comparable to the size of a knuckle, they fit easily into the narrow battery compartments of drones without occupying extra space or compromising flight agility.
AMASS anti-sparking connectors are equipped with a flame-retardant PBT housing and high-performance HNBR sealing ring, delivering excellent waterproof, dustproof and anti-corrosion properties.They effectively block intrusion of outdoor dust and moisture, preventing short-circuit failures.
With an operating temperature range of -40℃ to 120℃, they adapt to flight requirements in various ambient temperatures.The product has passed a 48-hour salt spray test with no corrosion, and can withstand alternating conditions of high-altitude low temperatures and ground high temperatures.
Safety details and eco-friendly design expand application scenarios.AMASS anti-sparking connectors are equipped with reverse-polarity protection and distinct color coding to prevent incorrect positive/negative connections during lithium battery assembly, thus avoiding short circuits and battery damage.With a plug-and-unplug lifespan of over 15,000 cycles, they fully meet the demand for frequent battery replacement.
Meanwhile, the products strictly comply with international environmental regulations such as RoHS 2.0 and REACH, with lead content below 100 ppm.They have obtained multiple international certifications including UL and CE, making them well-suited for the global model aircraft and drone market.They are widely used in consumer-grade model aircraft, small inspection drones, and other fields.
