50A 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 BCDC1250D Classic is the largest in the Classic range — a 12V 50A 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 around 150Ah to 400Ah. Rated for in-cabin installation only, not engine-bay use.
