        Intelligent Dual Battery Charging. Reliable Power.

        Designed for larger dual battery systems requiring faster charging and greater power delivery.


        The OCAM 40A DC-DC Battery Charger automatically manages charging from both your vehicle's alternator and connected solar panels. Its integrated Maximum Power Point Tracking (MPPT) technology extracts the highest possible output from your solar panels, helping keep your auxiliary battery charged faster and more efficiently.

        Whether you're heading off-road, towing a caravan or running a dual battery setup for work, the OCAM 40A DC-DC Battery Charger keeps your auxiliary battery charged safely and efficiently wherever you go.

        Designed for Australia's demanding conditions, the OCAM DC-DC charger intelligently draws power from your vehicle's alternator or connected solar panel, automatically selecting the most efficient charging source. Its integrated MPPT solar controller extracts maximum energy from your solar panel while advanced 3-stage charging maximises battery life.

        Compatible with both conventional and smart alternators, the OCAM charger is suitable for modern 4WDs, utes, caravans, camper trailers, motorhomes and touring vehicles.

        Designed to isolate the auxiliary battery from the cranking battery, this charger avoids over-discharging the cranking battery.  

        With IP68 waterproof construction, premium aluminium cooling fins and comprehensive electronic protection systems, it's built to keep working long after lesser chargers fail.
