If you want to make sure you'll never run out of power again, or you're after a tough and reliable battery charger that will keep you charged up even under the hottest sun, you've come to the right place!

Stay adventure-ready with the REDARC 25A Dual Input In-Vehicle DC to DC Charger. Designed to keep your auxiliary battery charged while driving on the roughest Aussie tracks, the REDARC BCDC1225D is the ultimate off-road unit for anyone planning to cross the outback or battle the wetlands. With its built-in solar panel compatibility, extreme weather resistance and three-stage charging, you'll never want to go off-roading again without this baby installed!

Built for the harshest Aussie environments by Aussie engineers, the REDARC BCDC1225D battery charger unit has been tested to work in the extreme heat of the Simpson Desert (up to 80 degrees C) and in the deep water crossings of Cape York! And if you have solar panels installed, this battery charger is the perfect choice for you - the REDARC BCDC1225D's Maximum Power Point Tracking solar regulator draws charge simultaneously from the solar panels and the alternators and, thanks to the built-in 'Green Power Priority', it will select solar charging first to lighten the load on your alternator.

The REDARC BCDC1225D features the same charging profiles as earlier models but adds a brand new lithium charging profile to extend its versatility even further by allowing it to charge AGM, Gel, Standard Lead Acid, Calcium and LiFePO4 batteries. The Three-stage DC to DC charging keeps your auxiliary battery charged at the optimum level, plus it can act as a dual battery isolator to protect your starter battery when the voltage drops below appropriate levels.

The REDARC BCDC1225D is suited for a battery bank size of 75-200AH, plus it boasts a wide operating range of 9-32V, meaning this charger will function well in both 12V and 24V systems and standard or smart/variable alternators. Best of all, the Smart Charger is compact, easy to install, and completely sealed to keep it protected from water, dust, and vibration. You won't find a more versatile battery charger than the REDARC BCDC 1225D - it's even suitable for marine applications!

The REDARC 25A DC to DC Charger BCDC1225D is delivered with a 2-year manufacturer's warranty covering faults and material defects.
