Tycab Red 4 B&S Single Core cable moves up to 135 amps on a typical 12 volt touring setup without stressing the line. The red sheath keeps the positive run obvious when you crawl under the tray with a head torch. The single core layout works well for linking start and auxiliary batteries on runs up to the length of a dual cab ute. The conductor packs 252 strands at 0.32 millimetres so bends around chassis rails stay neat without fighting the cable. The insulation rating of 90 degrees Celsius holds up in hot engine bays on long highway days. The 4 B and S size drops straight into common lugs and connectors on most aftermarket 4WD gear. Grab the metres you need and build a setup that will handle real Aussie driving.

Q: Is this Tycab 4 B&S cable suitable for 12V and 24V systems?

Yes, this 4 B&S single core cable suits both 12V and 24V low voltage DC systems. The 135 amp rating refers to current, not system voltage. You just need to size the length so voltage drop stays acceptable for your gear. Many dual battery and caravan setups use this size for charge and accessory feeds.

Q: Can I buy a continuous length longer than 1 metre?

Yes, the cable is sold per metre as a continuous length. Ordering 5 units gives a single 5 metre length, not five separate one metre pieces. You can then cut that length to suit your layout. Always leave a little extra for routing around corners and through grommets.

Q: What size lugs should I use with 4 B&S cable?

Use lugs specifically marked for 4 B&S or 25mm² cable. The cable diameter must match the lug barrel to get a solid crimp. Undersized lugs will not accept all 252 strands. Oversized lugs can lead to weak terminations and heat under load.

Q: Is this cable flexible enough for tight battery boxes?

Yes, the 252 fine strands at 0.32 mm give good flexibility compared with solid or coarse strand cable. This helps when routing into compact battery trays or around sharp turns. Still avoid kinking the cable to protect the copper strands. Secure runs with appropriate clamps or split conduit.
