REDARC BCDC1220 — 20A Under-Bonnet DC Battery Charger
Keep your auxiliary battery charging while you drive with the REDARC BCDC1220. This compact 12V, 20A DC-DC charger lives under the bonnet and delivers true multi-stage charging so your battery reaches and maintains a full charge, even on modern vehicles.
Built for Australian conditions, the unit is fully sealed and potted for heat, dust, water and vibration. It accepts 9 to 32V input, so it works on both 12V and 24V systems, and it applies the correct charge profile for AGM, Gel, Calcium, VRLA and standard lead-acid batteries. Quiet operation, tidy wiring, and optional stainless mounting brackets make for a neat, reliable install.
