Heavy-Duty Brass Battery Terminals – High-Amperage Pair

These heavy-duty battery terminals are engineered to meet the demands of high-performance electrical systems. The nickel-plated brass material combines excellent electrical conductivity with exceptional durability against rust and oxidation. Even in a harsh marine environment or under a car hood with moisture and acid fumes, these terminals maintain low electrical resistance and won’t degrade like regular lead clamps.

Each terminal is oversized and solidly built, allowing it to carry very high current effortlessly. This is ideal for large starter engines (such as V8 marine engines or high-compression diesels) and for setups with multiple batteries and powerful consumers (windlasses, inverters, amplifiers). The terminals feature stainless steel bolts to secure the cable lugs, which will not rust and provide consistent clamping force. A convenient feature is the clearly marked polarity (+ and –) on the terminals and fasteners – ensuring each cable goes to the correct post with no mix-ups. The broad contact surface to the post distributes current evenly, minimizing local heating. The result is a more reliable and long-lasting electrical connection that enhances the overall efficiency of your electrical system.

• For powerful engines: Recommended when installing batteries for large engines with very high cranking currents. For example, if your boat has a twin or eight-cylinder engine, these terminals ensure the massive starting current flows with minimal voltage drop.
• For marine environment: An excellent choice for yachts and powerboats – the nickel-plated brass and stainless bolts withstand salt air and spray, preventing corrosion. This means a reliable connection even after years of saltwater exposure.
• For high loads: Suitable for battery banks powering energy-hungry equipment – e.g., inverters, trolling motors, high-power audio systems or electric winches. These terminals won’t overheat or loosen during sustained high current, keeping your devices running stable.
• Easy upgrade: Replacing standard small clamps with these “big” terminals is straightforward, but the impact is significant – better conductivity, less power loss, cooler connections. They install like any regular terminal but give you peace of mind that your connections can handle the load.
