The Pro-Charge PDC25 is the evolution of Projecta's traditional IDC25 in-vehicle chargers, now with multi-chemistry support for both lead-acid (deep-cycle AGM) and Lithium (LiFePO4) batteries. Switchmode technology converts the vehicle's 12V or 24V alternator supply to the correct charge voltage with better than 94% efficiency at full load, and dual-input operation lets solar and alternator run together — with solar taking precedence and the alternator topping up when the panels can't keep up.

A sophisticated 3-stage charge process (bulk, absorption, float) with a calcium equalisation mode delivers a fast, complete charge and long battery life. The PDC25 works with both smart and conventional alternators via its ignition connection, and comes pre-wired with quick-connect Anderson HD connectors (grey, red, blue) plus three spares for a tidy install. Sealed to IP67 — dust, splash and shock proof, operating in temperatures up to 80°C.
