Summary

ARB REDARC 12V 40A Smart Start DC to DC Dual Input Battery Charger controls or connects part of the vehicle's auxiliary electrical system for charging and accessory power. A planned power-management component is safer and easier to service than adding unfused accessory wiring directly to the battery. The REDARC BCDC1240D under bonnet Battery Charger is a 12V 40A DC to DC battery charger, capable of high performance in engine bay installations, potted to survive and thrive against heat, water and dust.

Best For

  • Auxiliary-battery and camping-power installations.
  • Vehicles adding high-current accessories through a planned harness.
  • Replacing a known controller, charger or wiring component.

Current, Voltage And Cable Route

Start with the maximum current, cable length and battery chemistry. Locate protection close to the supply, keep high-current cables away from heat and moving parts, and leave access to fuses and connectors. Charging components must also suit smart-alternator behaviour where relevant.

Questions before you order

Frequently asked questions

How should cable size be chosen?

Use maximum current, circuit length, allowable voltage drop and the installation environment.

Is fuse protection still required with a harness?

Use the protection specified for the product and circuit; do not assume every harness contains all required fuses.

Will it work with a smart alternator?

Check the exact charger or isolator specification against the vehicle charging system.
