Built for Maximum Power Transfer & Safety
Avoid undersized wiring, hot cables, and messy battery bank connections.
Undersized wiring is one of the most common weak points in custom golf carts, RV inverter systems, marine battery banks, and off-grid solar builds. A true 4 AWG interconnect cable gives your power system a heavier current path than smaller factory-style leads when your system design calls for 4 gauge battery wire.
This 2-foot battery cable is short enough to keep installations neat while still offering enough reach for common battery-to-battery, battery-to-busbar, and battery-to-inverter connection points. Always pair high-amp battery wire with the correct fuse, breaker, torque, cable routing, and terminal protection for your specific system.
High-Amp Conductivity
4 AWG wire is significantly thicker than 6 AWG and is commonly used when battery banks, inverters, golf cart motors, or marine power systems require heavier current-carrying cable. Use your equipment manual and fuse rating to confirm proper cable size for the load.
Flexible, Heavy-Duty Insulation
Battery compartments, bilges, RV bays, and golf cart trays often require cable that can route around corners and hardware without excessive stress. This heavy-duty battery cable is designed for practical routing in tight power-system spaces.
Secure, Pre-Crimped Ring Terminals
The product image shows ring terminals already attached, helping DIY installers avoid buying expensive crimping tools. Verify the terminal hole size against your battery posts, inverter studs, busbar studs, or disconnect hardware before ordering.

Battery Bank Interconnects
At exactly 24 inches, this 4 AWG interconnect cable provides practical reach for adjacent battery terminals when wiring compatible batteries in series or parallel.
Golf Cart Cable Upgrades
Many golf cart owners upgrade battery cabling when switching to lithium or higher-power controllers. A properly sized 4 gauge battery wire can help reduce resistance compared with undersized cable when the whole system is correctly designed.
Inverters & Busbar Connections
Use this cable for compatible connections between a lithium battery, inverter, busbar, disconnect, or power distribution block when 4 AWG is the correct wire size for the current and run length.
Cable features
Practical wiring for cleaner battery banks and high-current power systems.
4 AWG heavy-duty cable Thicker than common light-duty battery wiring and better suited for high-current battery bank, inverter, and golf cart applications when system requirements call for 4 AWG.
24-inch / 2-foot reach A practical interconnect length for connecting adjacent batteries, busbars, disconnects, or inverter terminals without excessive wire loops.
Pre-crimped ring terminals Ready-to-install cable ends help eliminate the need for hydraulic crimpers and reduce the risk of poor DIY crimps.
Red and black wiring Helps installers identify positive and negative cable runs in battery banks and power systems.
Flexible routing Designed for battery compartments where cables must bend around trays, busbars, inverters, or golf cart frames.
Multi-use power connection Useful for golf cart cable upgrades, marine battery bank wiring, RV inverters, off-grid solar systems, and lithium battery interconnects.
Cleaner installations A properly sized pre-terminated cable helps reduce loose wiring, messy loops, and unreliable connection points.
Safety-first connection Heavy battery cables should always be paired with the correct fuse, breaker, torque specs, and terminal protection for the system.
Common companion components
Build a safer battery system by checking the whole power path.
✓ Epoch lithium batteries with compatible terminal hardware.
✓ Power distribution blocks, busbars, disconnects, and fuse holders sized for your current load.
✓ Properly rated terminal covers, heat shrink, cable clamps, and strain relief hardware.
✓ Lithium chargers, inverters, solar charge controllers, and DC-to-DC chargers with cable sizing verified by the manual.

Why cable quality matters
Heat, voltage drop, and poor terminations can limit your whole system.
Cheap, undersized, or poorly crimped cables can create resistance, heat, intermittent faults, and unsafe connections. A heavy-duty 4 AWG 24-inch battery cable helps simplify installation and supports cleaner power transfer when it is correctly matched to the load, fuse, battery terminals, and equipment requirements.
Fitment and safety note
Verify terminal size, current rating, and cable length before installation.
Epoch’s current listing confirms the product as a 4 AWG 24-inch heavy-duty battery cable and the image shows pre-attached ring terminals. Because the public listing does not publish ring-terminal hole size, exact amp rating, strand count, insulation rating, or cable material specification, verify compatibility with your battery posts, busbars, inverter studs, disconnect studs, and equipment manuals before installation.
4 AWG 24-Inch Battery Cable FAQs
Common questions about 4 gauge wire, battery bank interconnects, inverter connections, and cable fitment.
What is the difference between 4 AWG and 4 gauge wire?
There is no practical difference in this context. AWG stands for American Wire Gauge, and 4 AWG is commonly called 4 gauge battery wire. It refers to the cable size, with lower gauge numbers indicating thicker wire than higher gauge numbers.
Is 4 AWG wire thicker than 6 AWG wire?
Yes. In the American Wire Gauge system, the lower the number, the thicker the cable. A 4 AWG battery cable is thicker than 6 AWG and is commonly chosen for higher-current battery interconnects, inverter connections, and golf cart cable upgrades where the system design calls for heavier wiring.
Can I use this 24-inch cable to connect batteries in series or parallel?
Yes, this 4 AWG 24-inch battery cable is well suited for battery bank interconnects where the length, terminal fitment, and current rating match the system. It can be used as a series or parallel jumper cable in compatible 12V, 24V, 36V, and 48V battery banks. Always follow your battery and inverter manufacturer's wiring, fuse, and cable-sizing requirements.
Do I need a special tool to crimp the ends of this cable?
No. The product photo shows ring terminals already attached to the cable ends, so it is intended as a ready-to-install battery cable. You should still use the correct terminal hardware, torque specs, and protective covers for your battery, busbar, inverter, or disconnect connection.
What size are the ring terminals on this cable?
Epoch's current public listing confirms this as a 4 AWG 24-inch battery cable, and the product image shows pre-attached ring terminals. The listing does not publish the exact ring-terminal hole size, such as M8, 5/16 inch, or 3/8 inch. Verify your battery post, busbar stud, inverter stud, or disconnect stud size before ordering.
Can I use this cable in a boat, RV, golf cart, or outdoor battery compartment?
Yes, this type of heavy-duty battery cable is commonly used in marine, RV, golf cart, and off-grid battery systems when properly installed. Route it away from sharp edges, heat sources, moving parts, and standing water, and always protect the circuit with the correct fuse or breaker for the system.
Is this cable safe for inverter connections?
It may be used for inverter or busbar connections when the inverter current, cable length, fuse size, lug fitment, and installation environment are appropriate for 4 AWG wiring. For high-wattage inverters, always check the inverter manual and use the cable size required by the manufacturer.
Do I need red and black cables?
The Epoch listing SKU references red and black wiring, and the product image shows red and black cables with ring terminals. Use red for positive and black for negative where applicable, and label or protect all battery connections clearly to avoid reverse polarity.
