BATTERY DC WIRE 1.5 SQMM RED 100 MTR

Battery DC Wire 1.5 SQMM Red 100 MTR

The Battery DC Wire 1.5 SQMM Red 100 MTR is a flexible DC cable intended for compatible battery-pack wiring, auxiliary power circuits, BMS-related connections, electrical enclosures, control systems, and other low-voltage DC applications. It is supplied as a 100-meter length with a stated conductor cross-section of 1.5 square millimeters and red insulation for clear visual identification.

Within the ARB battery-wire range, 1.5 SQMM provides more conductor area than the 0.5, 0.75, and 1 SQMM variants. That makes it useful for circuits where the designer requires a larger cross-section to manage resistance, voltage drop, or electrical load while retaining a flexible wire format. It is still important not to assign a universal current rating from conductor size alone because allowable current depends on the complete cable construction and installation.

Technical Details

A 1.5 SQMM conductor provides a larger cross-sectional area than 0.5, 0.75 and 1 SQMM wires of the same material, which generally reduces resistance per unit length and can help limit voltage drop in compatible low-voltage DC circuits. This makes 1.5 SQMM useful for auxiliary power feeds and other circuits that need more conductor area while still benefiting from a flexible harness format. Final ampacity is installation-dependent and must account for conductor construction, insulation temperature class, run length, bundling, ambient temperature, protection device and termination quality.

Subject to electrical design, 1.5 SQMM DC wire may be used for auxiliary battery power wiring, small DC loads, charger or controller auxiliary circuits, relay feeds, control panels, battery test equipment, BMS-related power connections, equipment harnesses, and other low-voltage applications where this conductor size is specified.

Do not assume the wire is automatically suitable for a 1.5 SQMM-specific current level across every installation. A short wire in open air and a long conductor buried in a tightly packed harness can have different thermal and voltage-drop behavior. System voltage, conductor length, connection resistance, ambient temperature, bundling, insulation rating, and fuse coordination all matter.

The red insulation is useful for marking a positive path, especially when paired with a black cable of the same size. Always confirm polarity from the wiring diagram and by testing where appropriate. Color conventions improve organization but are not electrical protection.

Applications

• Auxiliary battery power wiring where 1.5 SQMM conductor size is appropriate.

• Small DC loads, relay feeds and controller auxiliary circuits.

• Control-panel, battery-test-equipment and BMS-related power connections.

• Equipment harnesses and low-voltage DC distribution wiring.

• Battery-pack production requiring red 1.5 SQMM wire supplied in a 100-meter roll.

Installation Guide

Use terminals or ferrules that properly accept 1.5 SQMM conductors. Strip insulation without damaging strands, and use a suitable crimping tool for the chosen terminal system. When several cables terminate in the same area, provide mechanical support so connector contacts are not carrying the weight or movement of the harness.

Protect the wire from abrasion at enclosure edges and route it away from heat sources. If the cable runs through a battery box, use grommets or sleeving where required. Keep bend radius reasonable and avoid crushing the cable under covers or fasteners.
