REDARC BCDC1220-IGN – The Ultimate Aussie 4WD DC-DC Charger
The REDARC BCDC1220-IGN is a rugged, multi-stage DC to DC dual battery charger designed to fully charge a lead acid auxiliary battery, even in the harshest Australian conditions.
Built for 4WDs, touring setups, and off-grid adventures, this 12V 20A DC-DC charger is perfect for vehicles fitted with an ECU-controlled variable voltage alternator. Fully potted and sealed, it shrugs off heat, water, dust, and vibration, making it ideal for off-roaders tackling the outback, beach runs, or Cape York crossings.
Designed for Tough Aussie Conditions
The BCDC1220-IGN is engineered with a lower voltage setting, ensuring continued operation even when the alternator delivers a low input voltage. It’s compatible with both 12V and 24V systems (operating range 9–32V), making it a versatile choice for serious 4WDers.
With tailored charging profiles for different battery types, this DC charger keeps your auxiliary battery in peak condition while driving—whether it’s powering a fridge, lights, winch, or other essential gear. Plus, it acts as a dual battery isolator, ensuring your start battery never gets drained.
