Heavy-Duty Battery Power Cable with Ring Terminals

Heavy-gauge red and black twin battery power cable with tinned copper ring terminals, 16 to 25 mm squared cross section. Pre-cut jumper lead for automotive, marine and solar battery bank hookups.

Overview

Heavy-gauge red and black twin battery power cable with tinned copper ring terminals, 16 to 25 mm squared cross section. Pre-cut jumper lead for automotive, marine and solar battery bank hookups.

Every assembly is built to the pinout, length and jacket specification agreed on the order, so the lead that arrives is the one the job actually needs rather than a generic part that mostly fits.

Key Specifications

Cable Type: Battery Power Cable
Conductor: Tinned Copper
Cross Section: 16 mm² – 25 mm²
Terminal Type: Ring Lug

Construction and Materials

Red and black conductors are run as a matched pair so the positive and negative runs stay the same length, which keeps resistance balanced across the link. Ring lugs are tinned copper, crimped and then heat-shrunk over the barrel to keep moisture out of the crimp. Tinning matters in engine bays and bilges, where bare copper would oxidise and slowly raise joint resistance.

Typical Applications

Typical uses include linking a starter battery to a leisure battery in a camper, feeding a winch or inverter from a battery bank, and wiring solar charge controllers to off-grid battery sets. The heavy cross section is sized for sustained current rather than brief cranking bursts, so it suits loads that run for minutes at a time.

Compatibility and Fitment

Supplied in the 16 mm2 to 25 mm2 range. Pick the cross section from the continuous current of the load and the one-way run length, not just the peak draw, and match the ring lug stud size to the terminal post before ordering.

Custom Builds and Ordering

Cable length, conductor cross section, jacket material and connector plating can all be specified per order. Send the pinout or a sample and the assembly will be built to match, with OEM and bulk packaging available for production runs.
