⚡ Heavy-Duty 120A Power Connection

The Razorback DC 120A connector provides a step up in current capability from the common 50A Anderson-style format.

It is ideal for appropriately designed applications including:

• Auxiliary battery feeds
• Lithium battery systems
• High-current charging
• Battery-to-battery connections
• Inverter connections
• Ute canopy power
• Caravan electrical systems
• Portable battery systems
• Solar battery systems
• Auxiliary power distribution

As a result, it is an excellent option when a standard 50A connection does not provide enough capacity for the intended circuit.

🔋 Perfect for Lithium Battery Systems

Modern LiFePO4 batteries are capable of supplying substantial current.

Therefore, connectors used between batteries and electrical equipment must be selected carefully.

The Razorback 120A connector can be incorporated into suitable systems connecting:

• Lithium auxiliary batteries
• Battery banks
• Main bus bars
• Fuse protection
• Charging equipment
• Inverters
• DC distribution systems
• Removable battery modules

Always ensure the battery BMS, cable, terminals and circuit protection are capable of supporting the expected load.

🚙 Ideal for 4WD & Ute Canopy Wiring

The 120A Anderson connector is an excellent choice for larger 4WD electrical systems.

Typical applications include:

• Ute canopy power feeds
• Auxiliary batteries
• Lithium systems
• DC power distribution
• Charging circuits
• High-current accessories
• Portable battery boxes
• Removable electrical equipment

For example, a 120A connection can provide a convenient disconnect point between a vehicle and a removable canopy electrical system.

🛻 Removable Canopy Power Connection

Removable ute canopies often require a substantial power connection between the vehicle and canopy.

A typical installation may use:

Vehicle Battery / Charging System → Fuse → 120A Connector → Canopy Electrical System

This allows the canopy power supply to be disconnected without removing bolted terminals or cutting wiring.

Consequently, canopy removal and servicing become considerably easier.

🏕️ Caravan & Camper Applications

The Razorback 120A Anderson Plug is also ideal for correctly designed caravan and camper electrical systems.

Suitable applications include:

• Auxiliary battery connections
• Lithium battery systems
• Battery charging
• External power connections
• Inverter systems
• Portable power equipment
• High-current DC distribution

The removable connector format also allows electrical equipment to be disconnected easily during maintenance.

🔌 Suitable for Charging Systems

The connector can provide a convenient high-current interface for compatible battery-charging systems.

Applications may include:

• Vehicle-to-canopy charging
• Battery-to-battery charging
• External battery chargers
• Portable charging equipment
• Solar battery systems

However, always check the maximum current of the charger and size the complete circuit accordingly.

☀️ Solar & Off-Grid Battery Systems

The 120A connector is also useful in larger solar and off-grid installations.

Potential applications include:

• Battery banks
• Portable solar systems
• Battery charging
• Main DC feeds
• Removable power equipment
• Off-grid electrical systems

For higher-current solar battery installations, cable length and voltage drop should always be considered.

🔄 Genderless Connector Design

Anderson-style connectors use a genderless design.

Rather than having conventional male and female housings, two compatible matching connectors mate directly together.

This simplifies:

• Installation
• Replacement
• Spare connector storage
• Battery-box wiring
• Portable equipment
• Removable electrical systems

🔐 Secure Removable Connection

Once properly assembled, the connector contacts are retained securely within the housing.

This creates a strong electrical connection while still allowing intentional disconnection when equipment needs to be:

• Removed
• Serviced
• Replaced
• Upgraded
• Transferred between vehicles

This makes the connector particularly useful for mobile electrical systems.

🎨 Colour-Coded Connections

Different connector colours can be used to help identify separate circuits.

For example, colour coding can help distinguish:

• Battery power
• Charging circuits
• Solar
• Auxiliary equipment
• Different voltage systems

Always use a compatible matching connector with the correct keying and colour configuration.

Do not assume differently keyed Anderson-style housings will mate together.

🔩 Correct Cable & Contact Selection

The safe cable size depends on the specific power contacts installed in the connector.

Always match:

• Cable conductor size
• Contact barrel size
• Crimping tool
• Circuit current
• Cable length

The connector housing rating alone does not determine the correct battery cable size.

🛠️ Professional Crimp Installation

For reliable high-current performance:

1. Select cable suitable for the electrical load.
2. Select contacts matched to the cable size.
3. Cut the cable cleanly.
4. Strip the insulation to the required length.
5. Insert the conductor fully into the terminal.
6. Crimp using a suitable heavy-duty crimping tool.
7. Inspect the completed crimp.
8. Insert the terminals fully into the housing.
9. Confirm polarity.
10. Test the circuit before applying full load.

Correct crimping helps minimise electrical resistance and heat.

📉 Voltage Drop Matters

In low-voltage DC systems, cable voltage drop becomes increasingly important as current and cable length increase.

Excessive voltage drop can cause:

• Reduced charging performance
• Inverter problems
• Equipment shutdown
• Cable heating
• Reduced system efficiency

Therefore, a cable may need to be larger than expected on longer runs even when the electrical load is below the connector's nominal rating.

🔥 Correct Fuse Protection

The 120A connector does not replace a fuse or circuit breaker.

Positive battery circuits should still use appropriately selected circuit protection.

Depending on the system, this may include:

• MIDI fuses
• MEGA fuses
• ANL fuses
• Circuit breakers

The protective device should primarily be sized to protect the cable and connected equipment.

⚠️ Understanding the 120A Rating

The 120A designation refers to the connector's current class.

It does not automatically mean every installation using the connector can continuously carry 120A.

Actual safe current depends on:

• Power contacts
• Cable conductor size
• Cable length
• Crimp quality
• Ambient temperature
• Installation method
• Duty cycle
• Connector condition

Every component in the electrical circuit must be correctly selected for the expected load.

💧 Outdoor & Automotive Use

The connector is suitable for demanding automotive and mobile applications.

However, a standard bare Anderson-style connector should not automatically be described as waterproof.

For exposed installations, consider additional protection such as:

• Protective boots
• Dust covers
• Weather-resistant mounting locations
• Cable protection

This is particularly important for external 4WD, caravan and machinery installations.
