The Epoch 84-inch CANbus Cable is the official long-run communication cable for Epoch GC2 lithium golf cart battery modules. It is built for custom golf cart installs, split battery compartments, extended module-to-module runs and dash-gauge routing, helping compatible GC2 modules share BMS data, synchronize communication and maintain accurate telemetry across the lithium battery system.
At 7 feet, it gives builders and technicians the reach to bridge split battery compartments, route around seat bases, or carry battery data from the battery bay to a dashboard display. Pre-terminated connectors install with no cutting, crimping or splicing. It is a communication accessory only; correctly sized power cables, fuses and disconnects stay in place for current-carrying connections.
Key Features
-
84-inch extended reach: A 7-foot cable gives installers extra distance for custom golf cart battery trays, split compartments, and longer dash-gauge routing paths.
-
GC2 battery BMS communication: Supports communication between compatible Epoch GC2 modules so the system can share data, synchronize operation, and provide more accurate battery telemetry.
-
Plug-and-play installation: Pre-terminated connectors keep installation simple, with no cutting, crimping or splicing required for compatible GC2 CANbus ports.
-
Cleaner custom builds: Reduces awkward routing, avoids stretched cables, and keeps GC2 lithium battery communication wiring organized.
-
Replacement or extension cable: Useful when the original cable is damaged, missing, or not long enough for a modified golf cart lithium installation.
-
Communication only: Carries data, not drive current. It does not replace power cables, battery interconnects, fuses, shunts or disconnect switches.

Essential for Custom Installs and Split Compartments
Give your Epoch GC2 communication cable the length needed for non-standard golf cart battery layouts.
Custom golf cart lithium installs often place GC2 battery modules farther apart than a standard side-by-side tray. This 84-inch data cable gives builders and technicians the reach needed to bridge split battery compartments, route around seat bases, or span longer paths while keeping each module connected to the battery communication network.
Use it when your build requires a clean 7-foot battery communication run instead of a short module bridge cable. It is a communication accessory only; always keep correctly sized power cables, fuses and disconnects in place for current-carrying connections.
Route Battery Data Directly to Your Dash
A practical long cable option for golf cart dash gauge and monitoring runs.
The 84-inch length is ideal for routing from an Epoch GC2 module under the seat or in a battery bay toward a dashboard display location. That makes it easier to keep accurate state-of-charge and system telemetry visible where the driver can monitor the lithium battery system during daily use.
Genuine OEM Quality: Plug-and-Play and Protected Routing
Avoid communication errors caused by unverified wiring and loose routing.
Genuine Epoch parts keep connector fitment, pinout compatibility and BMS communication aligned with your GC2 battery system. The pre-terminated plug-and-play design eliminates cutting and splicing, while proper routing helps protect the cable from vibration, pinching, moisture exposure and battery bay wear.
Maintenance and Care
Protect the cable for stable CANbus communication. Inspect the cable and connectors periodically for wear, damage, corrosion or loose connections. Route the 84-inch cable so it is not stretched, pinched, crushed, exposed to sharp edges, or placed against high-heat surfaces. Keep connectors fully seated and clean them with a soft cloth if dirt or corrosion appears.
Compatibility
- Epoch GC2 lithium golf cart battery modules
- Not intended as a universal cable for other lithium battery brands
- For modules mounted side by side in a tight tray, Epoch notes a shorter communication cable may be the better choice
Suitable For:
- Connecting Epoch GC2 batteries in parallel configurations that require communication linking
- Bridging split battery compartments in custom golf cart lithium conversions
- Routing GC2 battery communication from the battery bay toward a dash gauge or display
- Replacement or spare communication cable for compatible Epoch GC2 module systems
- Golf cart lithium battery telemetry, BMS data sharing, and coordinated multi-module operation
Please Note: Communication cable only. It carries data, not drive current, and does not replace power cables, battery interconnects, fuses, shunts or disconnect switches.

What is the CANbus cable used for on the GC2 modules?
The CANbus cable is the communication line between compatible Epoch GC2 golf cart battery modules. When multiple modules are installed together, the cable lets the internal battery management systems share data, support synchronized operation, and send accurate battery information to compatible monitoring equipment. Heavy-gauge battery cables still carry the power; this cable is for communication only.
Do I need this 84-inch cable if my batteries are right next to each other?
Usually no. If your GC2 modules are mounted side by side in a tight factory-style battery tray, shorter communication cables may be the better routing choice. This 84-inch / 7-foot CANbus cable is intended for custom layouts, split battery compartments, long module-to-module runs, or routing battery data up toward a dash display.
Can I use a generic CANbus or ethernet cable instead?
No. Even if the connector looks similar, generic network cables may use different internal wiring, shielding or connector designs. Use the official Epoch GC2 communication cable to help prevent communication errors, inaccurate gauge readings, or potential BMS issues in a vibrating golf cart battery bay.
Will this cable work with other brands of lithium golf cart batteries?
This cable is intended for Epoch GC2 golf cart battery modules. It should not be treated as a universal communication cable for other lithium battery brands unless the battery manufacturer confirms the connector, pinout and CANbus protocol are compatible.
Is the connector waterproof and durable?
The cable is built for golf cart battery bay communication use and should be routed in a protected location where it is not pinched, stretched, submerged, or exposed to excessive heat. Keep connectors fully seated and inspect them periodically for dirt, moisture, corrosion or vibration-related looseness.
How do I know which battery to plug the gauge cable into?
Follow the Epoch wiring diagram for your GC2 battery configuration. In a typical multi-module setup, the communication cables are daisy-chained from one battery to the next, and the available communication port on the designated master module is used for the dash gauge or monitoring cable. Confirm the correct port layout before powering the system on.
