This is a matched pair of 4AWG black and red ring-terminal-to-ring-terminal cables, 11 inches long, built to connect BigBattery lithium-ion battery systems to inverters, busbars, or other pack terminals without adding unnecessary resistance to the circuit.
Ring terminal cables are one of the most overlooked failure points in a battery bank. A loose or undersized connection here creates heat, voltage drop, and inconsistent power delivery long before any single cell degrades. This 4AWG pair is built for the ring-to-ring connections common in BigBattery lithium-ion setups, where clean current flow between batteries and inverters or busbars matters for both performance and safety. 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
- Wire gauge: 4 AWG, sold as a black and red pair.
- Length: 11 inches, ring terminal to ring terminal on each cable.
- Intended for BigBattery lithium-ion battery systems and general lithium-ion configurations noted by the manufacturer (mobile energy storage, golf carts, RVs, off-grid setups).
- Terminal lug hole size is not specified in the manufacturer data. [NEEDS VERIFICATION]
- Voltage rating is not specified in the manufacturer data. [NEEDS VERIFICATION]
- Ampacity limit is not specified in the manufacturer data. [NEEDS VERIFICATION]
- NOT verified for compatibility with non-BigBattery battery terminal layouts or lug spacing.
- NOT to be used beyond the wire gauge's rated current-carrying capacity — confirm ampacity against NEC 4 AWG copper wire tables for your installation conditions before sizing to a specific load.
Ring terminal connections that aren't torqued correctly are a common source of resistance heating in battery interconnects — even 4 AWG cable can't compensate for a loose lug. Over time, a loose connection cycles through heating and cooling, which loosens the joint further and can lead to thermal runaway at the terminal itself. Check every ring terminal connection with a digital torque wrench set to the terminal manufacturer's specification before energizing the system. This matches standard practice under NEC guidance for terminal lug torque compliance — don't estimate "hand tight" on a 4 AWG lithium battery circuit.
