Projecta IDC50X DC-DC Battery Charger

Product Overview

The Projecta IDC50X is a premium 50A DC-DC charger designed for serious off-grid power systems in 4WDs, caravans, campers, trucks, and marine applications. It’s built for users who run larger auxiliary battery banks and want fast, efficient, and safe charging in any environment. Whether you’re powering lithium batteries in a touring caravan, AGM batteries in a work vehicle, or mixed systems on a boat, the IDC50X has the flexibility and performance to keep your setup running reliably.

At the heart of the IDC50X is intelligent dual input functionality. The unit automatically manages both alternator and solar panel input, with no manual switching required. By prioritising solar first, it maximises renewable energy usage and reduces strain on the vehicle’s electrical system. Its built-in MPPT (Maximum Power Point Tracking) solar controller ensures the highest possible energy harvest from panels, even in challenging conditions like partial shading or cloudy skies.

The IDC50X offers true multi-chemistry support, delivering dedicated charging profiles for AGM, GEL, WET, Calcium, and LiFePO₄ lithium batteries. Each profile uses advanced multi-stage charging to extend battery life, prevent sulfation, and ensure full capacity is achieved. For lithium users, the charger includes a wake-up mode that reactivates batteries if their BMS has shut down from over-discharge.

Durability is a core strength of the IDC50X. Rated to IP68 and IP69K, it’s completely sealed against dust and water ingress, capable of surviving high-pressure hosing, river crossings, and the extreme vibration found in off-road and marine environments. With operating tolerance up to 90°C, it can be safely mounted in engine bays where space and airflow are limited. Inside, the electronics are fully potted in epoxy resin for maximum resistance to shock, moisture, and heat.

Projecta designed the IDC50X to be future-proof. When paired with the optional Intelli-IQ display or IQD2, users can monitor charging performance in real-time via Bluetooth on iOS or Android, access historical data, and update the firmware to keep the charger compatible with the latest battery technologies. For large systems, multiple IDC50X units can also be connected in parallel, providing scalable charging solutions for big lithium banks or heavy-duty setups.

Whether you’re crossing the Simpson Desert, living out of a caravan, or operating equipment in remote locations, the Projecta IDC50X ensures that your auxiliary batteries stay charged, protected, and ready to deliver power when you need it most.

Technical Specifications

Why Choose the IDC50X?

The IDC50X is more than just a battery charger; it’s a complete energy management solution for anyone who relies on auxiliary power in remote or demanding environments. Its 50A output makes it one of the strongest performers in its class, delivering fast charging for large lithium or AGM banks that would overwhelm smaller chargers.

By combining dual inputs, solar MPPT, and advanced charging profiles, it takes the guesswork out of maintaining your batteries. Users benefit from longer battery lifespan, more available capacity, and peace of mind knowing that their power system is protected against over-temperature, over-voltage, and reverse connection issues.

From 4WD enthusiasts who run fridges, winches, and camp lighting, to caravan owners running air conditioners and inverters, and marine operators with navigation and communications gear, the IDC50X is designed to keep your power system dependable. Built with rugged Australian conditions in mind, it will perform reliably where lesser chargers fail.
