Projecta IDC25X 12V 25A DC to DC Battery Charger with LINbus
The IDC25X is a 12V 25A DC to DC battery charger with LINbus communication, accepting 9 to 32V input for simultaneous solar and alternator charging. Supporting AGM, Gel, Wet, Calcium, and Lithium battery chemistries, it is guaranteed to deliver 25A output up to 75°C, is IP rated against vibration, heat, and water and dust ingress, and is backed by a 5-year warranty.
Product overview
The Projecta IDC25X is a DC to DC battery charger designed for dual battery systems in vehicles and mobile applications. The 9 to 32V input range accepts power from both 12V and 24V vehicle electrical systems, while the simultaneous solar and alternator charging capability allows the charger to draw from both a solar panel and the vehicle alternator at the same time to maximise charge rate to the auxiliary battery.
LINbus communication enables integration with the Projecta Intelli-IQ system, allowing the charger to be set up, monitored, and controlled remotely via smartphone app or the Intelli-IQ controller. When paired with the Intelli-IQ, the IDC25X can charge any battery chemistry, expanding beyond the standard supported types of AGM, Gel, Wet, Calcium, and Lithium.
The IDC25X is built to withstand demanding in-vehicle environments, with protection against vibration, heat, and water and dust ingress. A full protection suite covers over-temperature, reverse connection, over and under voltage, over current, and surge events. The guaranteed 25A output up to 75°C ensures rated performance is maintained even in high-temperature installation environments such as enclosed storage compartments and engine bays.
Features and benefits
Guaranteed 25A output up to 75°C: The IDC25X is guaranteed to deliver its rated 25A output at ambient temperatures up to 75°C, ensuring full charging performance is maintained in high-heat installation environments including enclosed storage areas and underbonnet positions.
9 to 32V input voltage range: Accepts input from both 12V and 24V vehicle electrical systems, making the IDC25X compatible with a wide range of vehicle platforms including passenger vehicles, 4WDs, trucks, and caravans.
Simultaneous solar and alternator charging: The IDC25X can draw from both a solar panel and the vehicle alternator simultaneously, combining both power sources to maximise the charge rate delivered to the auxiliary battery.
LINbus communication with app and Intelli-IQ control: LINbus enables remote setup, monitoring, and control of the charger via the Projecta smartphone app or the Projecta Intelli-IQ controller, providing full visibility over charge status and system performance from a mobile device.

Frequently asked questions
Can the IDC25X charge a lithium auxiliary battery from a standard alternator?
Yes. The IDC25X supports Lithium battery chemistry as standard and is designed to accept input from a vehicle alternator, making it suitable for charging a lithium auxiliary battery from the vehicle's charging system. Contact us for guidance on configuring the correct charge profile for your specific lithium battery.
What is LINbus and how does it work with the IDC25X?
LINbus is a communication interface that allows the IDC25X to connect with the Projecta Intelli-IQ controller and the Projecta smartphone app. This enables remote setup, monitoring, and control of the charger from a mobile device, without requiring physical access to the unit during operation.
Can the IDC25X charge from solar and the alternator at the same time?
Yes. The IDC25X supports simultaneous solar and alternator charging, drawing from both power sources at the same time to maximise the charge rate delivered to the auxiliary battery.
Is the IDC25X suitable for 24V vehicle electrical systems?
Yes. The 9 to 32V input voltage range accepts input from both 12V and 24V vehicle electrical systems. Contact us to confirm compatibility with your specific vehicle platform and auxiliary battery setup.
What additional battery chemistries can be charged when the IDC25X is paired with the Intelli-IQ?
When paired with the Projecta Intelli-IQ controller, the IDC25X can charge any battery chemistry beyond the standard supported types of AGM, Gel, Wet, Calcium, and Lithium. Contact us for further information on Intelli-IQ compatibility and supported chemistries for your specific battery.
