This is a 4 AWG black battery cable with a ring terminal crimped on each end, built for jumping connections between battery terminals, bus bars, or lugs in an ESS setup.
A 4 AWG ring-to-ring cable like this one is a common jumper for connecting battery terminals, bus bars, or lug points where a short, fixed-length run is needed. Ring terminals on both ends give you a bolted connection instead of a friction-fit clamp, which matters for long-term contact reliability under vibration or thermal cycling. 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.
Critical Fitment & Requirements
- Cable gauge: 4 AWG.
- Terminal style: Ring to Ring (bolted connection on both ends).
- Lug size: 1/4 inch stud diameter.
- Cable length: 11 inches, ring to ring.
- NOT compatible with terminal posts, bus bars, or lugs designed for M8 or M10 studs — the ring hole will not match a 1/4-inch stud fitting.
- Weight, exact cable length tolerance, and maximum rated temperature are [NEEDS VERIFICATION] — not provided by the manufacturer.
A ring terminal that isn't torqued to spec is a common source of resistance-related heating over time — even a 4 AWG cable can develop a hot spot at a loose lug connection under repeated charge/discharge cycles. Torquing the ring terminal to the stud manufacturer's spec, and re-checking it after the first thermal cycle, prevents the connection from loosening as the lug and stud expand and contract. Use a digital torque wrench rated for small fasteners rather than an impact driver — "snug" is not a torque spec. Confirm the ampacity of this 4 AWG conductor against the NEC Chapter 9 wire ampacity tables before assuming it covers your continuous load.
Key Benefits
- Bolted ring terminal connections on both ends reduce the risk of a slipped or arcing clamp connection versus a bare lug.
- 4 AWG conductor sized for higher-current jumper runs between battery terminals or bus bars.
- Fixed 11-inch length simplifies clean routing without needing to cut and crimp your own cable.
- Factory-terminated ends reduce field crimping errors on a critical high-current connection.

Compatibility & Fitment
- Fits battery terminals, bus bars, or lug connections accepting a 1/4-inch stud with a 4 AWG ring terminal on each end.
- Fits applications requiring an 11-inch ring-to-ring jumper cable.
- NOT compatible with hardware using M8 or M10 studs.
- NOT rated for use beyond the cable's unspecified ampacity and temperature limits — confirm continuous current draw against NEC ampacity tables for 4 AWG copper before installing on high-load circuits.
