REDARC BCDCWK-004 BCDC 50A Side by Side Engine Bay DC-DC Charger Wiring Kit

The REDARC BCDCWK-004 is a purpose-built wiring kit designed to simplify the installation of REDARC's 40A and 50A BCDC DC-to-DC battery chargers in engine bay applications where the start battery and auxiliary battery are located in close proximity — less than 0.6 m (2 ft) apart, side by side within the engine bay.

Compatible with the BCDC1240D and BCDC1250D dual-input battery chargers, this kit supplies everything needed to properly connect the BCDC charger between the two batteries. The cables in this kit feature a wider diameter and the fuses are higher-rated compared to the 25A wiring kits, making them suitable for the elevated current demands of 40A and 50A charger installations.

What's Included:

• Pre-crimped, cut-to-length Brown, Black, and Red power cables
• 150 mm (6 in) short Red cables (x2)
• Terminal block with plastic cover for solderless, lug-free cable connections
• MIDI fuse kit — 4 MIDI fuses (2 spares) and 2 MIDI fuse holders
• M5 × 25 mm socket head screws (x4), M5 nylon locking nuts (x4), and M5 flat washers (x4)
• Wago® connectors and boots (x2)

Key Features:

• Engineered for 40A and 50A BCDC DC-to-DC charger installations
• Designed for side-by-side engine bay configurations where batteries are within 2 ft of each other
• Pre-crimped cables and terminal block eliminate the need for soldering or custom lug terminals
• Cut-to-length cable design accommodates the specific dimensions of each installation
• Higher-rated fuses and wider-gauge cables suited for high-current applications
• Compatible with 12V AGM, GEL, Calcium, and Lithium Iron Phosphate auxiliary batteries

Note: The auxiliary battery ground cable and solar-to-Anderson cable are not included and must be purchased separately. This kit does not include a solar input cable — the Yellow solar cable is part of the BCDC charger only. Installation by a qualified auto electrician or technician is recommended.
