Intelli-Charge DC-DC Charger

Projecta's IDCX & INTELLI-IQ revolutionises dual battery systems. IDCX is the most advanced DC to DC charger, coupled with the INTELLI-IQ it creates limitless possibilities in controlling devices and accessories connected to the system.

Projecta's next generation DC to DC Dual Battery Charger starts with a clean sheet design. Taking what made the IDC great and developing a DC to DC Charger that pushes the envelope in every facet. IDCX range now features multi-chemistry DC-DC charging.

The sophisticated technology allows IDCX to charge WET, AGM, Calcium & Lithium batteries. The IDCX has 4 stage charging for for WET, AGM & Calcium batteries.

The first stage (BULK) charges the battery faster while the second stage (Absorption) ensures the battery is thoroughly charged. The fourth stage (Equalisation* Calcium Only*) returns a full hydrometer reading to calcium batteries by removing acid.

A 5 stage charge is delivered to a lithium battery. First stage (Soft Start 1) increases battery life by gently starting to charge the battery 5% of bulk. Second stage (Soft Start 2) increases battery life by gently starting to charge the battery 25% of bulk. The remaining 3 stages are bulk, absorption & float.


  • Linus Hub - The introduction of Linbus results in the ability to plug multiple devices into a LINBUS hub and have them controlled from he INTLLI-IQ
  • Smart Monitor - Intelli-IQ is Projecta's smartest monitor. It can display Start & Aux battery voltage, input/output current, programmable low power disconnect and much more.
  • Bluetooth Connectivity - Control up to 10 meters from the Intelli-IQ
  • Future Proof - Intelli-IQ firmware can be updated via Bluetooth, ensuring maximum reliability and functionality well into the future.
