This is a 4AWG red battery cable with ring terminals crimped on both ends, built for connecting battery terminals, bus bars, or lugs in a DC power system. It's a straightforward fit for anyone assembling or servicing a battery bank who needs a positive-lead jumper with a factory-crimped terminal on each end.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
A ring-to-ring cable removes the guesswork of matching a lug to a terminal post — both ends are already terminated, so you're bolting to bolt, not crimping in the field. That matters for battery bank wiring, where a loose or field-crimped connection is a common source of resistance heating and voltage sag. This cable uses a 1/4" ring lug on each end, which fits common battery post and bus bar hardware using that bolt size.
- Connector type: Ring to Ring Terminals (both ends terminated, no field crimping required)
- Terminal lug size: 1/4"
- Cable color: Red, indicating positive polarity
- Cable gauge, length, weight, and max rated temperature: Not specified by the manufacturer for this listing — [NEEDS VERIFICATION] before use in load calculations
- Does NOT fit: terminal posts, lugs, or bus bars requiring a bolt-hole size other than 1/4"
- Does NOT include: a specified voltage or ampacity rating in manufacturer data — do not assume a rating; verify before installing on a 48V or high-current run
Ring terminal connections loosen over time from thermal cycling, especially on cables carrying repeated charge/discharge surges. A loose ring lug increases contact resistance at the joint, which shows up as localized heating and, over enough cycles, can contribute to thermal runaway risk at the terminal. Torque every ring terminal connection to the bus bar or post manufacturer's spec using a digital torque wrench rather than hand-tightening — don't guess by feel. After torquing, verify the joint with a multimeter under load, checking for unexpected voltage drop across the connection. This lines up with NEC guidance on maintaining proper terminal torque and connection integrity for current-carrying conductors.
- Factory-terminated ring lugs on both ends — no field crimping required
- Red jacket color for clear positive-polarity identification in a battery bank
- 1/4" lug size matches common battery terminal and bus bar hardware
- Straightforward drop-in replacement for a ring-to-ring jumper in an existing DC harness

FAQ
What size are the terminal lugs?
The ring terminals on this cable have a 1/4 inch lug bolt-hole size on both ends.
What gauge is this cable?
This cable is labeled 4AWG. Manufacturer data did not specify actual conductor cross-section, cable length, weight, or maximum rated temperature, so confirm those details before use in a high-current application. [NEEDS VERIFICATION]
Is this cable rated for 48V systems?
Voltage rating was not provided by the manufacturer for this cable, so we can't confirm 48V suitability here. [NEEDS VERIFICATION] Check the Resources tab or ask us before you order if your system runs at 48V.
Does this cable come with terminals on both ends?
Yes. It's a ring-to-ring terminal cable, meaning both ends are crimped with 1/4 inch ring lugs, ready to bolt onto terminal posts or bus bars.
Warranty & Registration
Manufacturer warranty terms for this cable were not included in the supplied data. Please refer to the "Resources (System Manuals and Warranty)" Tab above on this page for the manufacturer's current warranty terms, or ask us before you order if you need that information confirmed.
