Redarc BCDC1225D In-Vehicle Dual Battery Charger – 25A

The Redarc BCDC1225D is a trusted, all-in-one dual battery charging solution designed for serious off-grid setups and touring adventures. Whether you're running a 4WD, camper, caravan, or canopy build, this unit ensures your auxiliary battery stays charged and ready – no matter where the road (or dirt track) takes you.

This 25A DC to DC charger is compatible with both standard and smart alternators and offers dual input charging – meaning it can charge from both your vehicle’s alternator and solar panels simultaneously. It works with AGM, GEL, standard lead-acid, calcium, and lithium batteries, making it a versatile option for a range of battery systems.

We’ve installed and used plenty of these in our time, and they continue to be a solid performer in both daily drivers and full touring rigs.

Pros:

• ✔️ Proven reliability – Trusted by 4WDers and installers Australia-wide.

• ✔️ Compact design – Easily mounted in engine bays or behind seats.

• ✔️ Smart charge profiles – Ensures long battery life and safe charging.

• ✔️ Redarc's Australian-made quality and 2-year warranty.

• ✔️ No extra solar regulator needed – saves space and cost in your setup.

Considerations (Cons):

• ❌ 25A charge rate may be slower for very large battery banks (e.g., 200Ah+ lithium setups).

• ❌ Not waterproof if mounted upside down or in a fully submerged environment.

• ❌ Does not include display or Bluetooth monitoring – requires additional gear for visual tracking.

Whether you're heading off-grid for the weekend or building a reliable touring setup, the Redarc BCDC1225D gives you dependable charging power wherever you go.
