The REDARC BCDC1225D Classic DC-DC Battery Charger delivers 25A of reliable charging power at 375W, engineered specifically for under-bonnet and external installations where durability is non-negotiable. Its integrated MPPT solar regulator uses Green Power Priority logic to automatically favour free solar energy over alternator draw — saving fuel and reducing wear on your vehicle's charging system. With an input voltage range of 9–32V, it's fully compatible with both standard fixed-voltage and modern smart/variable-voltage alternators, and it supports the full spectrum of battery chemistries including AGM, GEL, standard lead acid, calcium, and lithium LiFePO4 — all in a compact 165 × 120 × 37 mm form factor that weighs just 1 kg.
Built for Australian caravan, 4WD, and RV setups, the BCDC1225D is the go-to in-vehicle charger for travellers running dual-battery systems on extended outback runs, weekend caravan trips, or remote off-road adventures. Whether you're powering a fridge, lighting, water pump, or communications gear from a secondary battery, this unit keeps your auxiliary bank optimally charged on the move — day or night, sun or shade. Its compact size makes it ideal for tight engine bays in HiLux, LandCruiser, Ranger, and similar popular touring 4WDs, while bare-wire connections give full flexibility for custom installations in caravans, camper trailers, and motorhomes.
