Epoch Batteries LiMAX Big Box 13 ft Extended Harness

The Epoch Batteries LiMAX Big Box 13 ft Extended Harness Gives You the Reach for a Clean Dash Gauge Install on Longer Carts

The Epoch EP-HARNESS-V4-4M is a 13 ft (about 3.96 m) plug-and-play harness for Epoch LiMAX Big Box Series systems. It carries communication between the Big Box BMS and a compatible dash gauge or display, so you can mount the battery under the seat and the display on the dash without cutting or splicing wires.

It's made for stretched, 6-passenger, utility and custom golf carts where the standard harness may not reach the dash.

Epoch Batteries LiMAX Big Box 13 ft Extended Harness Features

13 Feet of Extra Reach

The 13 ft length gives you the slack to route the cable from the under-seat battery compartment, along protected frame paths and up to the dash on longer builds.

Plug-and-Play With No Splicing

OEM-style connectors mean no cutting, soldering or crimping. Splicing communication wires can cause display errors or intermittent gauge communication, so the complete harness keeps the connections intact.

Protective Corrugated Loom

A black corrugated loom covers the wiring to support routing along frame rails and through under-seat compartments.

Real-World Applications

Stretched 6-passenger carts. Reach the dash when the battery bay sits farther back.

Custom builds. Route the gauge cable on hunting buggies, utility carts and oversized carts.

Clean dash installs. Mount the LCD gauge on the dash without wires draped across the floorboard.

Practical Comparison

Extended Harness Versus Splicing the Standard Harness

Field-extended wiring adds joints that can cause signal faults and poor repairs. The 13 ft harness is one continuous run with its connector ends intact.

Extended Harness Versus a Power Cable

This is a low-voltage data and communication harness. It isn't a motor, controller, charger-output or battery main power cable.

Buyer Guidance

Confirm Your Battery and Connectors

This harness is for LiMAX Big Box Series systems only. It's not universal for every Epoch battery, every LiMAX model or every golf cart display. Compare your battery-side and display-side connectors before ordering, and never force a connector that looks different.

Route It With Care

Secure it with zip ties or insulated clamps. Keep it away from sharp edges, pinch points, hot components, suspension travel, tire spray and standing water, and leave a small service loop near the gauge.

This May Be A Good Fit If

• You have an Epoch LiMAX Big Box battery kit
• Your cart is stretched, 6-passenger or custom
• Your standard harness doesn't reach the dash

Common Questions

Do I Need This for a Standard 2-Seat Cart?

In most cases, no. The harness included with a LiMAX Big Box kit should reach on standard 2-passenger and many 4-passenger carts.

Can I Connect Two Harnesses Together?

Daisy-chaining isn't recommended. Extra joints can add moisture risk, interference, poor contact or diagnostic issues.

Will It Work for an EZGO Express or Club Car Stretched Cart?

It's commonly useful on longer carts such as an EZGO Express or a Club Car Villager-style cart. Final fit depends on your LiMAX Big Box kit, your gauge or display and the wiring path in your cart.
