REDARC BCDC Core40 — 40A In-Cabin DC-DC Battery Charger with Solar
The REDARC BCDC Core40 is a 40A DC-DC battery charger built for in-cabin and canopy installations. Charges your auxiliary battery from the alternator and solar simultaneously — Green Power Priority™ gives solar input preference to reduce alternator load and save fuel.
Compact, fanless and silent. Fits under seats, behind panels or inside a canopy battery box without taking up space or creating noise. 165 × 120 × 37mm and 900g.
Suits 12V and 24V smart alternators including Euro 5 and Euro 6 vehicles. No ignition wire required. Chemistry-specific charging profiles cover AGM, gel, calcium, standard lead acid and lithium (LiFePO4) — verified to charge to 100%.
Suited to lead acid battery banks over 200Ah and lithium batteries over 100Ah.
Not suitable for engine bay installation — in-cabin and canopy installs only. Professional installation by a qualified auto electrician recommended.
