Robust Construction & Safety Notes This Photonic Universe battery cable is constructed with a heavy-duty copper conductor and durable PVC insulation, designed for demanding environments. The pre-fitted, securely crimped eyelets help prevent loose connections and potential arcing, contributing to overall system safety. The black colour coding is crucial for maintaining correct polarity within your battery bank, reducing the risk of wiring errors. Common Questions What is the primary purpose of this black battery cable? This cable is specifically designed to connect the negative terminals of multiple batteries within a single battery bank, ensuring proper electrical continuity and system integrity. Can this cable be used for positive connections? No, this black cable is intended for negative terminal connections to maintain clear polarity identification. For positive connections, a red battery cable link of the same specification should be used. What does 35mm² signify for a battery cable? 35mm² refers to the cross-sectional area of the cable's conductor. This heavy-duty gauge indicates it can safely carry significant electrical current, making it suitable for high-power battery bank applications. What size are the eyelets on this cable? The cable is fitted with 8mm diameter metal ring terminals (eyelets) on both ends, designed to fit standard battery posts or busbar connections. Installation Notes Always disconnect power from the battery system before performing any wiring or connections. Ensure correct polarity: use black cables for negative connections and red for positive connections. Tighten all eyelet connections securely to prevent high resistance, heat build-up, and potential arcing. Route cables carefully to avoid sharp edges, excessive bending, or areas of high heat. For complex battery bank installations, consider consulting a qualified electrician or solar installer. Before You Buy Verify the required cable length for your specific battery bank layout to ensure a neat and safe installation. Confirm that the 8mm eyelet diameter matches your battery terminals or busbar connection points. Ensure the 35mm² cross-section meets the current requirements of your solar, automotive, or marine system. If you also need to link positive terminals, remember to purchase a corresponding red battery cable link. Check the voltage of your battery system (e.g., 12V, 24V, 48V) to ensure compatibility with the cable's typical ratings. Please verify all specifications and compatibility requirements for your specific battery system before purchase. Professional installation is recommended for optimal safety and performance.
