REDARC BCDC 1225D – Dual Input 25A DC-DC Battery Charger

See our “Lead Time” page for current and estimated Lead Times.

The REDARC BCDC1225D In-vehicle Dual Battery Charger is a 12 volt, 25A in-vehicle DC-DC battery charger designed to charge your secondary battery banks to 100% state of charge while on the move.The current generation alternators are often too smart for their own good. The variable voltage output of these alternators is great for fuel economy, but not great for keeping an auxiliary battery charged. It isn’t sufficient to just run an isolator. That isolator is not going to allow your auxiliary battery to charge to full capacity in any timely manor since the alternator often runs at a voltage less than maximum. The BCDC eliminates this issue by stepping up the voltage in three stages, allowing proper, monitored charging. REDARC has been doing this for a long time and we at AAL fully trust their knowledge and recommendations when it comes to properly maintaining the electrical systems in off road vehicles.
