4AWG Customized Cable Battery Cables Customized Panel Inverter Battery Wire

Product Specification

This 4AWG battery cable assembly is designed for DC power connection between batteries, inverters, and distribution panels. It is commonly used in energy storage systems, inverter installations, automotive power systems, and industrial DC applications.

The cable is manufactured using fine-stranded copper conductor with optional tinned copper treatment, combined with durable insulation and pre-installed terminals. It is suitable for both standard configurations and fully customized cable assemblies based on project requirements.

Key Features

Stable High Current Transmission

The 4AWG conductor size provides a balanced solution for medium to high current applications, ensuring stable DC power delivery between battery banks and inverter systems with controlled voltage drop.

Copper / Tinned Copper Conductor Options

Available with oxygen-free copper or tinned copper conductors to improve conductivity and enhance corrosion resistance in long-term operation environments.

Pre-Assembled Terminal Structure

Each cable can be supplied with pre-crimped terminals for direct installation. This reduces on-site assembly time and improves connection consistency in panel and inverter systems.

Flexible Multi-Strand Design

Fine stranded construction improves flexibility, making the cable easier to route inside inverter cabinets, battery enclosures, and tight installation spaces.

Industrial Grade Insulation

Insulation materials such as PVC or rubber compounds provide resistance against abrasion, oil exposure, and mechanical wear in industrial environments.

Custom Manufacturing Available

This product is fully customizable according to project specifications, including cable length, terminal type, insulation color, and packaging requirements.
