REDARC BCDC1220-IGN 20A Ignition Control DC DC Charger

The REDARC BCDC1220-IGN 20A Ignition Control DC DC Charger is an Australian-made charging solution designed for vehicles fitted with ECU-controlled variable voltage alternators. Built for harsh Australian conditions, this compact and powerful DC DC charger delivers reliable charging for auxiliary batteries while protecting your start battery.

Designed for under bonnet installation, the BCDC1220-IGN is fully sealed against water, dust and vibration. As a result, it performs reliably in demanding environments, including off-road touring, marine applications and commercial vehicles.

Whether you’re powering a fridge, lighting system, communications equipment or other accessories, the BCDC1220-IGN helps ensure your auxiliary battery remains charged and ready for use.

Designed for Variable Voltage Alternators REDARC BCDC1220-IGN

Many modern vehicles use variable voltage alternators controlled by the vehicle’s ECU. These systems can make it difficult for traditional charging systems to fully charge auxiliary batteries.

The REDARC BCDC1220-IGN solves this problem by operating with a low input voltage range. Therefore, it continues charging even when alternator voltage drops.

As a result, your auxiliary battery receives the charge it needs throughout your journey.

Ideal for Dual Battery Systems REDARC BCDC1220-IGN

The BCDC1220-IGN is designed specifically for dual battery installations.

It allows your auxiliary battery to charge while driving. Meanwhile, the start battery remains protected from excessive discharge.

This makes it ideal for:

• 4WD vehicles
• Touring vehicles
• Camper trailers
• Caravans
• Marine applications
• Work vehicles
• Service vehicles

Furthermore, the built-in battery isolator helps prevent your start battery from being accidentally drained.

Intelligent Multi-Stage Charging REDARC BCDC1220-IGN

The REDARC BCDC1220-IGN uses advanced multi-stage charging technology.

Rather than applying a simple charge, it delivers a charging profile suited to the battery type being used. Consequently, battery performance and battery life are improved.

Benefits include:

• Faster charging
• Improved battery condition
• Longer battery life
• Maximum charging efficiency
• Reliable operation while driving

As a result, your auxiliary battery remains healthier and performs better over time.

Compatible Battery Types

The BCDC1220-IGN supports a range of common battery chemistries including:

• Standard Lead Acid
• AGM
• Gel
• Calcium
• VRLA Batteries

Please note:

This charger is not suitable for Lithium LiFePO4 batteries.

If you are running a lithium battery system, consider one of REDARC’s lithium-compatible BCDC chargers instead.

Built Tough for Australian Conditions

REDARC designs, builds and tests its products in Australia.

The BCDC1220-IGN is fully sealed and built to withstand:

• Dust

• Extreme temperatures

Additionally, the unit is potted for extra protection against harsh operating conditions.

Whether you’re crossing rivers, travelling corrugated roads or working in remote areas, the BCDC1220-IGN is built to perform.

Under Bonnet Installation

Unlike many chargers, the BCDC1220-IGN is suitable for engine bay installation.

Its compact size and robust construction make it ideal for mounting under the bonnet where space is limited.

REDARC also offers vehicle-specific mounting brackets designed to simplify installation and improve airflow around the charger.

These brackets are manufactured from durable stainless steel and utilise existing mounting points where possible.
