300A Battery Terminals with Covers, Pair of 2, M10

The 300A battery terminals with covers are electrical connectors used to connect cables to a battery. They are typically nickel-plated brass for better conductivity and come with M10 studs on both the front and back for secure connection.

Technical Specifications:

  • Current Rating: 300 Amps
  • Material: Typically nickel-plated brass for conductivity and corrosion resistance
  • Stud Size: M10 (metric thread standard) on both front and back for secure connection to cables with compatible lugs
  • Includes: Covers to protect the connection from external factors


  • High Current Capacity: This is ideal for applications requiring significant current flow, such as car audio systems and off-road vehicles.
  • Secure Connection: M10 studs and compatible lugs ensure a tight and secure connection, minimising resistance and reducing the risk of overheating or power loss.
  • Corrosion Resistance: Nickel-plated brass construction offers superior corrosion resistance, crucial in marine environments or high-humidity areas.
  • Protection Against Dirt and Debris: Covers shield connection points from contaminants, preventing corrosion and electrical shorts.
  • Protection Against Accidental Short Circuits: Covered terminals provide additional protection, safeguarding against damage to electrical components or fires.


  • Improved Electrical Performance: High-conductivity materials and secure connections minimise voltage drops, ensuring efficient power transfer.
  • Reduced Maintenance: Corrosion-resistant materials and protective covers minimise maintenance needs by preventing terminal degradation.
  • Enhanced Safety: Protection against accidental short circuits and exposed connections contributes to a safer electrical system.
  • Professional Appearance: High-quality terminals with a clean, finished look enhance the overall aesthetic of car audio systems or electrical installations.

Safety Considerations:

  • Use Compatible Cables and Lugs: Ensure the cable gauge and lug type match the terminal’s M10 stud size for proper fit and secure connection.
  • Tighten Terminals Properly: Over-tightening can damage threads, while under-tightening can lead to loose connections and overheating.
  • Insulate Exposed Cables: Insulate any exposed cable beyond the connected lug to prevent accidental shorts.
  • Disconnect Battery Before Installation: Always disconnect the battery’s negative terminal before working on the electrical system to avoid potential shocks or sparks.

In essence, 300A battery terminals with covers offer a reliable, high-current connection for demanding applications. Their features make them ideal for car audio systems, inverters, off-road vehicles, and more. These come with all mounting screws and gaskets required. Available at
