The stalwart charger has greatly improved performance and features.


Projecta’s IDC25 was a favourite DC to DC charger for many years, but the replacement IDC25X was designed to perform in temperatures as high as 90°C, making it suitable for under-bonnet fitment.



At launch in mid-2023, the IDC25X was said to provide a full 25A charge up to 75°C, where competitor chargers reduce charge at 55°C by up to half. Key to this performance was the IDC25X ’s use of fully-potted thermal epoxy resin that drew heat away from the electronics to the outer housing. 

The units were tested to vibration and shock Heavy Vehicle Standards and IP68 and IP69K ratings, ensuring protection against ingress of dust, water and even high-pressure water, should owners want to thoroughly clean their engine bays. 

Allowing owners to customise their battery management systems, the IDC25X’s multi-chemistry technology supported charging of AGM, GEL, WET, Calcium and Lithium batteries with pre-set charging modes.  

The unit also offered Automatic Temperature Compensation, further protecting valuable batteries.

For users wanting to mount the IDC25X at a distance from the battery, the unit was equipped with ‘Voltage Drop Compensation’, which maintained correct charge voltage. 

The IDC25X also had a built-in solar controller that prioritised solar charging as default and automatically adjusted the vehicle alternator output, using Intelli-Charge if there’s insufficient sunlight available. A proprietary MPPT (Maximum Power Point Tracking) algorithm also ensured maximum solar efficiency, even in reduced sunlight. Compared to the earlier IDC25, the IDC25X was more efficient in harnessing solar power and could also accommodate solar inputs of up to 360W.  

Owners could monitor the performance of the IDC25X, using an ‘Intellix-IQ’ smart display, supported by an App compatible with smart phones and tablets, letting them adjust battery charge profiles and even set-up future charging parameters to suit new batteries as they enter the market.  

Intellix-IQ incorporated LINbus technology, allowing up to 15 devices to be connected to a LINbus hub that could be controlled via the Intelli-IQ display or on a smart device via Bluetooth. LINbus also gave the IDC25X the ability to natively communicate, allowing parallel charging with multiple IDC25X units, without overcharging.

Software/firmware updates via Bluetooth included a forthcoming g automatic Lithium Wake Up mode.

Projecta’s IDC25X DC/DC charger was backed by a five-year warranty and sold at a recommended retail price of $595.
