REDARC DUAL BATTERY ISOLATOR DC TO DC CHARGER AGM SLA BCDC1220IGN KIT
Couldn't load pickup availability
The REDARC BCDC1220IGN is a 12V/24V DC-to-DC battery charger rated for 20 ampere output that charges auxiliary batteries from vehicle alternator input using ignition-triggered activation. This unit features three-stage charging algorithm (boost, absorption, float), automatic battery isolation when ignition is off, and charging profiles compatible with AGM, gel, calcium, and standard lead-acid battery types. The IGN designation indicates ignition sensing capability for compatibility with low-voltage smart alternator systems found in post-2010 vehicles. The complete installation kit includes the charger unit, dual voltage gauge with red LED displays, battery cable, and connection hardware.
