Built for Maximum Power Transfer and 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 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 cable is designed for practical routing in tight power-system spaces.
-
Secure, pre-crimped ring terminals: Ring terminals come already attached, helping DIY installers avoid buying expensive crimping tools. Verify the M8 terminal hole size against your battery posts, inverter studs, busbar studs or disconnect hardware before ordering.
Perfect for Any 12V, 24V, 36V or 48V Application
Use it where a short, heavy-duty, pre-terminated battery cable is required.
-
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 and 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.
Common Companion Components
Build a safer battery system by checking the whole power path.
-
Batteries: Epoch lithium batteries with compatible terminal hardware.
-
Distribution and protection: Power distribution blocks, busbars, disconnects and fuse holders sized for your current load.
-
Terminal protection: Properly rated terminal covers, heat shrink, cable clamps and strain relief hardware.
-
Charging and conversion: 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 simplifies 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. The cable is a 4 AWG, 24-inch heavy-duty battery cable with pre-attached M8 ring terminals and a 70A to 95A maximum rating. Strand count, insulation rating and cable material are not published, so verify compatibility with your battery posts, busbars, inverter studs, disconnect studs and equipment manuals before installation.

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. It is well suited for battery bank interconnects where the length, terminal fitment and current rating match the system, and 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. Ring terminals come already attached to the cable ends, so it is 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?
The technical specifications list an M8 terminal hole size. 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 SKU references red and black wiring, and the cable comes in red and black 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.
