RC-MR30 Battery Connector Pair (3-Pole, 30A, 2mm)

The RC-MR30 Connector Pair is a compact, high-performance 3-pole power connector designed for reliable connections between ESCs, motors, and LiPo battery systems. Built for demanding RC and electronic applications, it delivers stable current transfer, secure connectivity, and long-term durability in a lightweight, space-efficient design.

Detailed Description

Engineered for performance and reliability, the MR30 connector features 2mm gold-plated brass bullet terminals that provide excellent conductivity, low resistance, and minimal power loss. This ensures efficient power transfer and stable operation in high-demand applications such as drones, RC vehicles, robotics, and motor control systems.

Its polarized male/female configuration prevents incorrect mating and reverse polarity, improving system safety and installation accuracy. The connector also features assistive weld foot construction, providing improved soldering stability and stronger cable termination.

Constructed with durable PA66 insulation material, the MR30 offers excellent heat resistance, mechanical strength, and electrical insulation. A protective snap-on sleeve adds extra safety by shielding the connection and reducing the risk of accidental short circuits.

Designed for repeated use, the connector supports up to 3000 mating cycles while maintaining strong electrical performance. With low internal resistance and high current capability, it is an excellent solution for compact, high-efficiency power systems.
