REDARC

<h3>About REDARC Electronics</h3><p><strong>REDARC Electronics</strong> is an Australian-owned advanced electronics manufacturer with a legacy stretching back over 45 years. <a href="/13879-redarc-battery-charger-14307">Battery chargers</a>, <a href="/13879-redarc-trailer-brake-control-module-50173">trailer brake controllers</a>, solar solutions, and power management systems — REDARC has spent decades engineering products that don't just survive the harshest environments, but thrive in them.</p><p>The company was founded in August 1979 by electronics engineer Robin (Bob) William Mackie in Lonsdale, South Australia, where it remains headquartered today. Mackie began the business designing vehicle ignition systems — and the name REDARC is said to come from the distinctive &quot;red arc&quot; spark produced by that very first ignition system. After Mackie's passing, Anthony and Michele Kittel took ownership in 1997 and have since transformed REDARC from a small South Australian workshop into a globally recognized electronics brand.</p><h3>Engineering Built for the Long Haul</h3><p>REDARC's reputation is built on products engineered to perform in real-world, demanding conditions. Every product in the lineup is designed, tested, and manufactured in their South Australian facility — a commitment to quality that has earned the brand a loyal following among RV owners, overlanders, truckers, and marine enthusiasts worldwide. Their electronics feature fully sealed, potted construction designed to resist water ingress, dust, vibration, and extreme temperatures.</p><p>The brand's <a href="/13879-redarc-battery-charger-14307">battery charger</a> lineup is a cornerstone of what REDARC does best. Their BCDC (Battery Charger DC to DC) series and multi-stage smart chargers support a wide range of battery chemistries — including lithium, AGM, gel, and lead acid — making them a go-to choice for dual-battery setups in trucks, 4x4s, and camper vans. Some models integrate an MPPT solar regulator directly into the charger, consolidating what would otherwise require multiple separate components.</p><h3>The Tow-Pro: A Benchmark in Brake Control</h3><p>Perhaps no REDARC product is better known than the Tow-Pro series of <a href="/13879-redarc-trailer-brake-control-module-50173">trailer brake controllers</a>. The Tow-Pro Elite and Tow-Pro Liberty offer proportional braking that responds in real time to the towing vehicle's deceleration — delivering smoother, safer stops whether you're on a freeway or navigating rough terrain. These controllers are engineered to fit a wide range of trucks, SUVs, and tow vehicles, and are compatible with 1- to 3-axle trailers. For a complete installation, REDARC also offers dedicated <a href="/13879-redarc-electric-brake-control-wiring-harness-15424">electric brake control wiring harnesses</a> designed to simplify the connection process and ensure a clean, reliable install.</p><h3>Off-Grid Power for Every Adventure</h3><p>As solar power has become increasingly popular for caravans, campers, and overlanding rigs, REDARC has developed a comprehensive range of <a href="/200973-solar-powered-chargers-redarc-13879">solar powered chargers</a> to keep auxiliary batteries topped up wherever the road leads. Their solar solutions range from rigid monocrystalline panels to portable solar blankets designed for use on uneven or shaded terrain. Paired with REDARC's battery management systems, these <a href="/200973-solar-powered-chargers-redarc-13879">solar chargers</a> form part of a fully integrated off-grid power ecosystem.</p><p>For builders looking to organize their dual-battery setup neatly, REDARC also offers a <a href="/11671-battery-tray-redarc-13879">battery tray</a> designed to securely mount auxiliary batteries alongside BCDC chargers — keeping everything tidy under the hood or in the cargo area.</p><h3>A Brand That Sets the Benchmark</h3><p>REDARC's stated goal has always been to set the standard by which its competitors are measured — a philosophy backed up by decades of patented innovations, award-winning products, and a no-questions-asked warranty policy introduced in 1997. Whether you're crossing a desert, towing a fifth wheel, or building a van conversion, REDARC offers an integrated suite of power and towing electronics trusted by serious adventurers around the world.</p>

Product Details

The REDARC BCDC1225D is an advanced dual-input, in-vehicle DC-DC battery charger that delivers professional-grade power management for auxiliary battery systems in 4x4s, RVs, camper vans, trailers, and marine applications. This 25-amp continuous output charger is designed to charge secondary battery banks to 100% state of charge while on the move, utilizing power from both your vehicle's alternator and solar panels simultaneously.

Dual Input Charging Technology:

  • MPPT Solar Regulator: Built-in Maximum Power Point Tracking extracts maximum efficiency from solar panels, whether roof-mounted or portable
  • Green Power Priority: Automatically prioritizes solar input when available, reducing load on your vehicle's alternator and electrical system
  • Simultaneous Charging: Accepts DC power from vehicle (9-32V range) and solar input at the same time for faster, more efficient charging
  • 375W Output Power: Delivers consistent 25A charging current to quickly replenish battery banks

Universal Battery Compatibility:

Features selectable multi-stage charging profiles optimized for AGM, Gel, Standard Lead Acid, Calcium Content, and LiFePO4 (Lithium) batteries. The microprocessor-controlled charging algorithm ensures each battery type receives the precise voltage and current profile for optimal performance and longevity. Suitable for battery bank sizes of 75-200Ah in most applications.

Built for Extreme Conditions:

  • Fully sealed, potted electronics resist water, dust, and vibration
  • Operating temperature range: -10°C to 80°C (14°F to 176°F)
  • Proven in deep water crossings and harsh off-road environments
  • Fan-free cooling design eliminates moving parts for enhanced reliability
  • IP-rated protection against environmental infiltration

Smart Vehicle Integration:

Compatible with both 12V and 24V vehicle electrical systems. Works seamlessly with standard alternators and modern variable-voltage/smart alternators found in newer vehicles. The wide 9-32V input voltage range compensates for voltage drop over long cable runs, ensuring optimal charging even in large vehicles or trailers.

Technical Specifications:

  • Continuous Output Current: 25A
  • Output Power: 375W
  • Input Voltage Range: 9-32V DC (vehicle and solar)
  • Charging Profiles: 14.6V (AGM/Gel), 15.0V (Standard Lead Acid), 15.3V (Calcium), 14.5V (LiFePO4)
  • Float Voltage: 13.3V or 13.6V depending on profile
  • Recommended Input Fuse: 40A (REDARC FK40 fuse kit sold separately)
  • Standby Current: <8mA
  • Compact Dimensions: 165mm L x 120mm W x 37mm H (6.5" x 4.7" x 1.5")
  • Weight: 850g (1.87 lbs)

Installation and Monitoring:

The unit features 7 LED indicators on the front panel to display charging profile selection and real-time charge status. Compact footprint allows flexible mounting locations including engine bay, under seats, or in battery compartments. Professional installation by a qualified auto electrician is recommended.

Award-Winning Australian Engineering:

This SEMA Global Media Award-winning charger is designed and manufactured in Australia by REDARC Electronics, a company with over 45 years of experience in power management systems. Extensively tested in the harsh Australian Outback, REDARC products are trusted worldwide for their durability and performance. Backed by a 2-year manufacturer warranty.

Note: For DIY installation, REDARC recommends purchasing the FK40 40-amp fuse kit separately for proper overcurrent protection.

Easy to do

Smooth so far.

Quick and easy. Hope they have shoes in stock.

I just received my Knn filter. Shipment was on time. The box look beat up and deformed with a lot of tapes but the filter seems to be in good condition.

easy

always quick &amp; easy also bought hotchkis front sway from here no problem &amp; best price -free shipping

easy site to maneuver, fast checkout!

The billing address and the shipping address could not be changed on my phone and would not accept once logged on via the computer. Took forever. Every time I would go back to change all my information was lost and had to repeat all of the steps.

The ordering process was simple and user friendly. The pricing was the lowest I could find for a brand new AMP Powerstep for my Ford F150. The tracking number was provided and the item is scheduled for FedEx ground delivery in 3-days.

Lowest prices on name brand items, quick shipping, and provide information on the status of your order.

Great so far an great prices
