REDARC BCDC Classic25 12V 25A DC Battery Charger

Keep your aux battery topped up while you drive with the REDARC BCDC Classic25. This 12V, 25A in-vehicle DC charger is built for under-bonnet life and will bring your secondary battery bank to a proper state of charge from alternator and solar. It’s compact, potted, and ready for heat, water, dust and vibration, so it’s right at home in Aussie touring rigs.

The Classic25 includes an MPPT solar regulator and Green Power Priority, which means it uses available solar first and eases the load on your alternator. It works with both 12V and 24V vehicles, including smart/variable-voltage alternators, and supports modern chemistries like LiFePO4 along with AGM, Gel, Calcium and standard lead-acid. For most setups it suits battery banks of 75–200Ah; step up to the 1240D for larger capacity systems.

Built and tested in Australia, the BCDC Classic range is proven in extreme heat and rough tracks, from desert corrugations to creek crossings. If you rely on fridges, lights and inverters off-grid, this unit keeps your batteries ready.
