REDARC- 20A In-Vehicle DC Battery Charger (Ignition Control)



The REDARC BCDC1220-IGN is a multi-stage DC to DC dual battery charger which features technology capable of fully charging a lead-acid auxiliary battery. It’s designed for vehicles fitted with an ECU-controlled variable voltage alternator. The battery charger is designed to work with an operating range of 9-32V and gives the option for charging from either 12V or 24V vehicle systems.

Low voltage setting

The BCDC1220-IGN has a lower voltage setting and will continue to operate with a low input voltage from the alternator. Should the voltage get too low, the unit acts as a dual battery isolator and protects the start battery.

Built tough for all conditions

It’s compact in size and fully sealed to eliminate the risk of damage from dust, water, and vibration. It can handle the toughest trails and roughest terrains and can operate under extreme heat (up to 176°F). Plus,  fan cooling makes for quiet operation. The DC-DC battery charger, charges AGM, gel, calcium content, VRLA, and standard lead-acid batteries. The BCDC range charges your auxiliary battery banks to 100% state of charge while on the move and on to your next great adventure.
