600mm of 50mm² Battery Parallel Cable Pair

Made-to-order 50mm² battery parallel cable pair

This matched pair contains two 600mm leads made from RALOS HF1X50SDI 50mm² flexible SDI cable. Each lead is professionally crimped with your selected Exotronic 50mm² bellmouth lugs at both ends, providing four tinned-copper lug terminations in total. Red and black heat shrink identifies the positive and negative leads.

Flexible, halogen-free cable for demanding DC installations

RALOS flexible SDI cable uses an annealed Class 6 bare-copper conductor, X-HF-110 insulation and an orange HFS-110-TP outer sheath. Its halogen-free construction is rated to 110°C and is suited to battery banks, inverters, busbars, solar and energy-storage systems where flexibility and robust insulation matter.

• Complete pair: two 600mm leads with four selected lug terminations
• RALOS cable: 50mm² HF1X50SDI flexible SDI
• Halogen-free construction: X-HF-110 insulation with an orange HFS-110-TP sheath
• Temperature rating: -40°C to +110°C
• Exotronic lugs: fully annealed C11000 tinned-copper bellmouth terminals for fine-stranded cable
• Polarity identification: red and black heat shrink at both ends

Free-air current-carrying capacity

Reference current-carrying capacity: 276A. This is the AS/NZS 3008.1.1:2017 Table 6 value for two single-core flexible copper cables with 110°C X-HF-110 insulation, unenclosed and spaced in free air at 40°C ambient air temperature. The pair rating is not doubled: one lead carries outgoing current and the other carries return current.

Derating and cable selection: This reference value is not a universal circuit rating. Correction and derating factors apply for ambient temperature, grouping or bundling, installation method, enclosure, thermal insulation and other heat sources. The complete circuit must also be designed for voltage drop, run length, termination ratings, overcurrent protection and duty cycle by a suitably qualified person.

Reliable bellmouth terminations

The flared entry on each Exotronic bellmouth lug guides fine cable strands into the barrel without splaying. Fully annealed, electro-tinned copper supports a clean crimp and a corrosion-resistant, low-resistance connection.
