Amass Anti Spark AS150S Male Connector – AS150S-M.G.B Drone Connectors

Product Description

The Amass Anti Spark AS150S Male Connector (AS150S-M.G.B) is a premium-grade high-current anti-spark DC power connector designed for safe and reliable power connection in agriculture drones, industrial UAV systems, RC vehicles, electric mobility solutions, robotics, and high-capacity lithium battery packs. Manufactured by Amass, a globally recognized leader in professional connector technology, the AS150S series is engineered to solve one of the biggest problems in high-power systems—sparking during battery connection.

The AS150S-M.G.B Male Connector features a built-in anti-spark (pre-charge) design, which reduces inrush current when connecting high-voltage lithium battery systems. This helps prevent damaging electrical arcs, protects sensitive electronics like ESCs and BMS units, and improves the overall safety of the power system. It is especially useful in 12S–14S drone and UAV battery setups, where connection sparks can otherwise damage connector surfaces over time.

The connector uses precision-machined brass contacts with gold plating, ensuring excellent conductivity, very low resistance, and stable high-current performance. The gold plating also improves corrosion resistance, allowing long-term durability even under frequent connection cycles and harsh outdoor conditions.

Designed for high-power applications, the AS150S connector supports approximately 75A continuous current and up to 150A peak capability (depending on system design and wire gauge), making it suitable for heavy-duty UAV propulsion systems and industrial battery packs. It is also rated for 500V DC operation, making it compatible with modern high-voltage drone architectures.

The housing is made from high-temperature PA66 (Nylon) thermoplastic with flame-retardant properties, offering excellent insulation, mechanical strength, and thermal stability. The rugged design ensures resistance against vibration, shock, and environmental stress—critical for drones and mobile robotics operating in real-world conditions.

A key highlight of this connector is its anti-spark resistor-based pre-charge system, which gradually equalizes voltage during connection. This significantly reduces stress on capacitors in ESCs and BMS systems, improving overall system lifespan and safety.

Whether you're building an agricultural drone, assembling a high-voltage battery pack, or working on industrial robotics, the Amass AS150S Male Connector provides a safer, more reliable alternative to standard high-current connectors.
