Redarc BCDC1212S BCDC Trailer S 12V 12A trailer DC-DC battery charger with 40A solar regulator
The Redarc BCDC Trailer S (BCDC1212S) combines a 12 A DC-DC trailer battery charger and a 40 A solar regulator in a single unit. It keeps your trailer or caravan battery charged while driving, reducing your reliance on mains charging.
The built-in isolator prevents accidental draining of the vehicle battery, while input current management protects wiring and fuses. It works with 12 V and 24 V vehicles and with lead-acid, calcium, Gel, AGM and LiFePO4 batteries.
