DC to DC battery chargers

Compact in size, easy to install and suitable for 12 or 24 volt vehicle systems, REDARC's dual battery chargers work with either standard, voltage alternators or smart alternators.

Choose between under bonnet or in-cabin DC-DC chargers

The REDARC range of dual battery chargers features the rugged, under bonnet capable BCDC Classic range that are fully sealed and potted to survive and thrive under extreme heat, as well as being water, dust and vibration proof. While the BCDC Core chargers are ideal for in-cabin, canopy or boot installations offering all of the market leading features without being fully potted, saving you money on your dual battery setup.

Do you love using 4WD solar panels on your 4WD? REDARC's DC to DC battery chargers feature next generation battery charging technology, and are able to charge from Solar and DC inputs simultaneously.
