SoloGood Amass XT90 Bullet Connectors

1. Introduction

This manual provides essential information for the safe and effective use of your SoloGood Amass XT90 Male and Female Bullet Connectors. These connectors are designed for high-current applications, offering a reliable and secure connection for RC Lipo batteries, motors, and other electronic components. Please read this manual thoroughly before installation and operation.

2. Safety Information

• Always ensure proper polarity when connecting. Incorrect polarity can cause severe damage to components and pose a fire hazard.
• Soldering should be performed in a well-ventilated area. Use appropriate safety gear, including eye protection.
• Avoid short-circuiting the battery terminals. The XT90 connectors are designed with protective housings to minimize this risk, but caution is always necessary.
• Do not exceed the specified current ratings (90A continuous, 120A peak) to prevent overheating and potential failure.
• Keep connectors away from children and pets.

3. Product Overview

The Amass XT90 connectors are known for their robust design and high-performance capabilities. They feature gold-plated 4.5mm banana plugs housed within high-temperature resistant nylon material, ensuring durability and excellent conductivity.

4. Setup and Installation

Proper soldering is crucial for the performance and safety of XT90 connectors. Follow these steps carefully:

1. Prepare Wires: Strip approximately 5-7mm of insulation from the ends of your 10AWG (or suitable gauge) wires.
2. Pre-tin Wires and Connectors: Apply a small amount of solder to the stripped wire ends and the cups of the XT90 connector pins. This ensures a strong bond.
3. Insert Wires: Place the pre-tinned wire into the corresponding connector cup.
4. Solder Connection: Apply heat to the connector cup and wire simultaneously with a soldering iron (recommended temperature: 480°C for 4 seconds). Once the solder flows, remove the iron and allow the joint to cool without movement.
5. Use a Mating Connector: To prevent the pins from shifting or the plastic housing from deforming due to heat, it is highly recommended to plug a mating connector into the one you are soldering. This acts as a heat sink and maintains alignment.
6. Attach Housing: Once cooled, slide the protective housing onto the soldered connector. The housing clicks into place, securing the connection and preventing exposed wires. Note that the end cap is designed for a tight fit and may be difficult to disassemble once installed.

5. Operating Instructions

Connecting and disconnecting XT90 connectors is straightforward:

• Connecting: Align the male and female connectors, ensuring the correct orientation. Push them firmly together until they are fully seated. A secure connection will feel snug.
• Disconnecting: Grip both the male and female connector housings firmly and pull them apart. Avoid pulling on the wires, as this can damage the solder joints or the wires themselves.

6. Maintenance

To ensure the longevity and optimal performance of your XT90 connectors:

• Cleaning: If connectors become dirty, clean them with warm, soapy water. Ensure they are completely dry before use to prevent short circuits.
• Inspection: Periodically inspect connectors for any signs of wear, corrosion, or damage to the housing or pins. Replace damaged connectors immediately.
• Reusability: These connectors are designed to be reused up to 1000 times under normal operating conditions.

7. Troubleshooting

• Difficulty Soldering: Ensure your soldering iron is at the correct temperature (480°C) and that both the wire and connector cup are properly pre-tinned. Using a mating connector during soldering can help manage heat and prevent deformation.
• Loose Connection: If a connection feels loose, inspect the pins for damage or deformation. Ensure the housing is fully seated. A loose connection can lead to resistance and heat buildup.
• Overheating: If connectors become excessively hot during use, verify that the current draw does not exceed the connector's specifications. Check for poor solder joints or damaged pins that could increase resistance.
