The 3.5mm Gold Bullet Connector Pair is the industry standard for high-current, low-resistance connections in the RC and robotics world. At Electrapac, we recommend these connectors for brushless motor setups and battery power leads where maintaining a solid electrical bond under high vibration is critical.

Product Overview

These connectors consist of a precision-machined male plug and a matching female socket, both heavily gold-plated to prevent oxidation and ensure maximum conductivity. The "spring-lantern" design on the male end ensures a tight, constant-pressure fit that won't vibrate loose, making them far superior to standard barrel jacks for high-performance applications.

Key Features for Electrapac Customers

• Low Resistance / High Efficiency: The gold plating minimizes voltage drops, ensuring your ESC (Electronic Speed Controller) and motor receive maximum power without generating excess heat at the joint.

• Vibration-Resistant "Spring" Fit: The male connector features multiple spring-contact leaves that expand inside the female housing, providing a 360-degree connection that stays secure during high-RPM flight or driving.

• Easy to Solder: Features a "cup" style soldering end that makes it easy to pool solder and insert your wire for a professional, mechanically strong bond.

• Compact & Lightweight: Their slim profile makes them ideal for tight spaces inside drone frames or small RC car chassis where bulky connectors like XT60s won't fit.

• Modular Design: Unlike fixed plugs, bullet connectors allow you to easily swap motor wires to reverse motor direction without re-soldering.

Soldering & Safety Guide

To get the best performance from your www.electrapac.com connectors:

1. Safety First: When using these on batteries, always put the female connector on the "Live" (Battery) side and the male on the "Load" (ESC) side to prevent accidental short circuits against metal frames.

2. Heat Shrink: Always use 4mm or 5mm heat-shrink tubing to insulate the exposed metal after soldering.

3. The "Third Hand" Trick: Use a wooden clothespin or a "helping hand" tool to hold the connector while soldering, as the metal becomes extremely hot very quickly.

Primary Applications

• Brushless Motors: The standard connection between an Outrunner motor and its ESC.

• LiPo Batteries: High-discharge battery packs for drones, planes, and RC cars.

• Robotics: Power distribution for high-torque servo motors and actuators.

• DIY Power Links: Custom high-current cables for portable power stations or test benches.

Why Shop at Electrapac?

We source 3.5mm Bullet Connectors with extra-thick gold plating to ensure they don't lose their conductivity after multiple plug/unplug cycles. Visit www.electrapac.com to find these in pairs or bulk packs, along with high-quality 14 AWG silicone wire and heat-shrink tubing.
