25A DC-DC + MPPT SOLAR
Dual input — alternator and MPPT solar controller in one in-cabin unit.
GREEN POWER PRIORITY
Solar takes precedence over the alternator when the panels are producing — saves fuel.
LITHIUM AND AGM READY
Six charge profiles cover AGM, gel, calcium, standard lead-acid, LiFePO4 and custom.
HARDWIRED IGNITION TRIGGER
Our workshop hardwires an ignition trigger on smart-alternator vehicles and multi-charger setups so all chargers only run when the vehicle is running.
2 YEAR REDARC WARRANTY
Backed by 2 years direct from Redarc. Repair or replacement in accordance with Redarc's warranty policy.
The REDARC BCDC1225D Classic is a 12V 25A DC-DC battery charger for a 12V auxiliary battery bank, with a built-in MPPT solar regulator. Charges from your vehicle's alternator, solar panels, or both at once — Green Power Priority uses solar first to reduce alternator load and save fuel.
Six charge profiles cover AGM, gel, calcium, standard lead-acid, LiFePO4 lithium and custom setups. Fanless, in-cabin design.
Smart alternator vehicles and multi-charger setups. Our workshop always hardwires an ignition trigger to the charger on late-model vehicles with stop-start or variable-voltage smart alternators, and on any build with more than one BCDC (for example a charger in the vehicle plus a second charger in the caravan) so all chargers only run when the vehicle is running. Ask us if you're unsure whether your vehicle needs this.
Output is 12V. The 9-32V input range means it will run on a 12V or 24V vehicle, but the output is always 12V. For a 24V system, use the Redarc BCDC2420 instead.
Sized for battery banks between roughly 75Ah and 200Ah. Rated for in-cabin installation only, not engine-bay use.
