BATTERY DC WIRE 2.5 SQMM BLACK 100 MTR

BATTERY DC WIRE 2.5 SQMM BLACK 100 MTR

The BATTERY DC WIRE 2.5 SQMM BLACK 100 MTR is a 2.5 mm² battery/DC wire supplied in a 100 metre length for battery pack wiring, low-voltage DC distribution and electrical assembly work. The black colour supports circuit identification during harness building and service. Buyers may search for 2.5 sqmm battery wire, 2.5 mm2 DC cable, battery pack wire or 100 metre DC wire roll.

The 2.5 mm² cross-section is the key sizing value confirmed by the product name, but conductor material, strand count, insulation compound, temperature rating, voltage rating and certified ampacity were not confirmed. These properties materially affect the current a cable can carry without excessive voltage drop or heating. In battery systems, cable performance also depends on total run length, ambient temperature, bundling, enclosure ventilation, duty cycle and terminal quality. A cable should therefore be selected from an engineering current/voltage-drop calculation rather than a single universal amp rating. Red and black are normally used as polarity identifiers in DC systems, but installers should still verify polarity electrically before energising a harness.

Use this 2.5 mm² wire only where the calculated current, voltage drop and thermal conditions are suitable. Match terminals and ferrules to the actual conductor construction and use a crimp tool that produces a secure gas-tight joint without cutting strands. For battery-pack internal wiring, keep high-current paths short and protect the cable from sharp cell holders, metal enclosure edges and hot components. If the system is subject to vibration, use strain relief and secure routing points.

For procurement and production use, compare the physical item with the approved sample before standardising the bill of materials. Check dimensions, connector or mounting geometry, supplied accessories and any markings that identify the exact variant. Where the application has a safety-critical electrical, thermal or mechanical requirement, use the manufacturer datasheet for the stocked part rather than a visually similar market product. Recording the approved item code and revision helps prevent a replacement part with the same generic name but different construction from entering the assembly process.

Applications

• Battery pack internal and external DC wiring where 2.5 mm² is correctly sized.

• Low-voltage power distribution in EV, inverter and energy-storage assemblies.

• Harness production, repair and workshop cable preparation.

• Control and auxiliary DC circuits when the current requirement matches.

• Prototype battery systems and test-bench wiring.

Installation Guide

Plan the cable route before cutting so the run has enough service slack without unnecessary length. Strip insulation with a correctly sized tool, crimp or terminate using hardware matched to the conductor, and insulate exposed terminals. Keep positive and negative cables physically controlled during assembly to prevent accidental short circuits. After installation, verify polarity, continuity and connection resistance before applying load, then check for abnormal heating during initial operation.

Why Choose ARB Accessories?

ARB Accessories focuses on lithium-battery, EV, energy-storage and battery-pack assembly components. The catalog brings together BMS boards, connectors, insulation materials, battery wiring, terminals, fuses, enclosures, testing equipment and assembly tools. For battery builders, repair workshops and OEM buyers, sourcing related components from one specialist catalog can make specification matching and procurement easier. Final suitability should still be checked against the exact battery design, equipment model and electrical requirements before installation.
