REDARC 20A Ignition Control Under-Bonnet DC Charger

REDARC BCDC1220-IGN — 20A Ignition Control Under-Bonnet DC Charger

Keep your aux battery charging while you drive, even on vehicles with smart alternators. The REDARC BCDC1220-IGN is a compact 12V, 20A multi-stage DC-DC charger with an ignition trigger and a low-input voltage setting, so it keeps working when alternator voltage drops. It’s fully sealed and potted for under-bonnet life, handling heat, water, dust and vibration without fuss.

It supports a wide 9–32V input, so you can charge a 12V auxiliary battery from both 12V and 24V systems. Select the correct profile for your battery chemistry and the charger will bring it to an optimal state of charge while protecting your start battery with built-in isolation. Quiet, fan-free operation and optional stainless mounting brackets make for a neat, reliable install.
