The Projecta PDC25 Dual Battery Charger is designed to do exactly that. It takes power from your vehicle’s alternator or your solar panels and turns it into the correct charging voltage for your auxiliary battery, helping to keep it healthy and ready to go on every trip.\u003c\/p\u003e\n\u003cp\u003eDesigned for both 12V and 24V systems, the PDC25 is a smart DC–DC charger that’s built with Australian touring in mind. It offers MPPT solar charging for maximum efficiency from your panels, and it’s fully compatible with modern smart alternators. The tough, sealed alloy housing is made to handle dust, water and heat, so you can mount it in engine bays, canopies or under trays with confidence.\u003c\/p\u003e\n\u003cp\u003eWhether you’re camping on the weekend, heading off on a longer overland run, or just want reliable power for work accessories, the Projecta PDC25 keeps your dual battery system charged, protected and ready to perform.\u003c\/p\u003e\n\u003ch3\u003eTotal Environmental Protection\u003c\/h3\u003e\n\u003cp\u003eThe PDC25 is fully sealed to an IP67 rating, giving you protection against dust and water ingress. It’s engineered to cope with heat, vibration and harsh conditions, making it suitable for mounting in demanding locations around your 4WD, trailer or caravan.\u003c\/p\u003e\n\u003ch3\u003ePlug and Play Installation\u003c\/h3\u003e\n\u003cp\u003eTo make installation simpler, the charger is pre-wired with colour-coded 50A heavy-duty connectors. This helps reduce wiring mistakes and speeds up the fitment process. Extra 50A connectors are included so you can easily hook up alternator and solar inputs as well as your auxiliary battery output.\u003c\/p\u003e\n\u003ch3\u003eDual Input Operation\u003c\/h3\u003e\n\u003cp\u003eThe PDC25 can charge from both your vehicle’s alternator and solar input, and it can make use of both at the same time. This dual input operation helps you get the most out of your charging system, cutting down charge times and keeping your batteries topped up whether you’re driving, parked up at camp or doing a mix of both.\u003c\/p\u003e\n\u003ch3\u003eMPPT Solar Charging\u003c\/h3\u003e\n\u003cp\u003eWith built-in MPPT (Maximum Power Point Tracking) solar technology, the charger constantly adjusts to get the best possible output from your solar panels. That means more efficient charging and better results in changing light conditions compared with basic PWM regulators.\u003c\/p\u003e\n\u003ch3\u003eTotal Safeguard Protection\u003c\/h3\u003e\n\u003cp\u003eThe PDC25 is loaded with safety features to protect both your batteries and your vehicle. It includes protection against reverse connection, over-voltage and under-voltage, over-temperature and sparks. This reduces the risk of damage from incorrect wiring, poor connections or harsh operating conditions and helps extend the life of your batteries.\u003c\/p\u003e\n\u003cp\u003ePut simply, the Projecta PDC25 Dual Battery Charger takes the guesswork out of managing your auxiliary battery, giving you a robust and efficient charging solution that’s ready for real-world Australian conditions.\u003c\/p\u003e\n\u003ch3\u003eSpecifications \u003c\/h3\u003e\n\u003ctable data-start=\"92\" data-end=\"1058\" class=\"w-fit min-w-(--thread-content-width)\" style=\"width: 99.9972%;

The IDC25X steps up with IP68\/IP69K sealing (versus IP67 on the PDC25), full thermal epoxy potting for vibration resistance, guaranteed 25A output up to 75°C, and optional Bluetooth monitoring via the Intelli-IQ app. For light to moderate touring, the PDC25 is a solid performer. For under-bonnet fitment in harsh conditions or extended remote travel, the IDC25X is worth the premium.\u003c\/p\u003e\n \u003c\/details\u003e\n \u003cdetails\u003e\n \u003csummary\u003eDoes it come with Anderson connectors or do I need to buy extras?\u003c\/summary\u003e\n \u003cp\u003eThe PDC25 comes pre-wired with colour-coded 50A heavy-duty Anderson connectors and includes additional connectors for the alternator input, solar input, and auxiliary battery output.

Standard 12V panels (which produce 18-22V under load in peak conditions) are a natural match, but 24V panels whose open-circuit voltage approaches or exceeds 28V should not be connected. Always check your panel's open-circuit voltage spec against this limit before wiring it up.\u003c\/p\u003e\n \u003c\/details\u003e\n \u003cdetails\u003e\n \u003csummary\u003eCan it use solar and alternator at the same time?\u003c\/summary\u003e\n \u003cp\u003eYes. The PDC25 supports dual-input operation, drawing from both your alternator and solar panels simultaneously. This is particularly useful on camp park-ups where solar charges through the day while an earlier drive gave the system an initial boost from the alternator.\u003c\/p\u003e\n \u003c\/details\u003e\n \u003cdetails\u003e\n \u003csummary\u003eDoes it work with modern smart alternators?\u003c\/summary\u003e\n \u003cp\u003eYes. The PDC25 is compatible with both smart (variable voltage) and conventional alternators. For 12V vehicles with smart alternators, it activates when input voltage reaches 12.2-20V. For 24V vehicles, the threshold is 24.4-32V. For conventional alternators on 12V vehicles, the turn-on threshold is 13.4-20V.\u003c\/p\u003e\n \u003c\/details\u003e\n \u003cdetails\u003e\n \u003csummary\u003eWill it charge a lithium battery correctly?\u003c\/summary\u003e\n \u003cp\u003eYes. The PDC25 supports lithium at a 14.2V charge profile, as well as AGM (14.4V), Wet (14.7V), and Calcium (14.7V). Select the correct chemistry during installation so the right voltage is applied to your battery, using the wrong profile on a lithium battery can shorten its life.\u003c\/p\u003e\n \u003c\/details\u003e\n \u003cdetails\u003e\n \u003csummary\u003eIs IP67 adequate for engine bay or under-tray mounting?\u003c\/summary\u003e\n \u003cp\u003eIP67 provides full dust protection and temporary water immersion resistance, making it suitable for many engine bay, under-tray, canopy and trailer mounting setups, provided the location is within Projecta's mounting and temperature guidance.
