Pure Copper Construction
The lug is made from pure copper, providing excellent electrical conductivity for high-current battery connections.
Pure copper helps provide:
Excellent conductivity
Low electrical resistance
Efficient current transfer
Reduced connection losses
Reliable battery connections
This makes it particularly suitable for high-current LiFePO4 battery and inverter applications.
Nickel-Plated Finish
The copper lug features a nickel-plated surface.
Nickel plating provides additional protection against:
Oxidation
Corrosion
Surface deterioration
Environmental exposure
It also provides a durable surface for repeated professional battery installations.
Designed for 25mm² Cable
This lug is designed for use with:
25mm² Battery Cable
It is an ideal matching terminal for 25mm² pure copper flexible DC battery wire.
The combination of a properly sized cable and correctly installed lug helps provide a reliable high-current connection.
Suitable LiFePO4 Battery Applications
These 25mm² lugs can be used for appropriately designed:
12V LiFePO4 Batteries
12.8V 100Ah
12.8V 200Ah
24V LiFePO4 Batteries
25.6V 100Ah
25.6V 200Ah
25.6V 314Ah
48V / 51.2V LiFePO4 Batteries
51.2V 100Ah
51.2V 200Ah
51.2V 314Ah
Important: The battery's Ah capacity does not determine lug size by itself. The lug should be selected according to the cable size, terminal stud size and required current.
Suitable Applications
🔋 LiFePO4 Battery Packs
Ideal for making reliable high-current connections between battery cells, busbars, BMS wiring and external battery terminals where compatible.
⚡ Inverter Batteries
Suitable for battery-to-inverter connections when used with appropriately sized cable and terminals.
☀️ Solar Systems
Can be used in solar battery and energy-storage installations.
🏠 Home Backup
Suitable for residential LiFePO4 battery systems and backup-power installations.
🔌 UPS Systems
Useful for high-current DC connections in compatible UPS battery systems.
🚗 EV Battery Packs
Can be used for suitable EV battery connections where the cable and terminal specifications match the required current.
🏢 Commercial Energy Storage
Suitable for appropriately designed commercial and industrial battery systems.
Installation
For a reliable connection:
Use the lug with the correct 25mm² cable.
Strip the cable to the appropriate length.
Fully insert the copper conductor into the lug barrel.
Use a suitable heavy-duty crimping tool.
Ensure the crimp is secure and mechanically strong.
Connect the lug to the appropriate terminal stud.
Tighten the connection according to the equipment manufacturer's recommended torque.
Ensure the connection is clean and properly insulated.
Important
Do not rely on solder alone for a high-current battery cable termination. Proper mechanical crimping with an appropriately sized lug is recommended.
Why Use Nickel-Plated Copper Lugs?
Compared with an unprotected copper surface, nickel plating provides additional surface protection while retaining the excellent conductivity of the copper base.
