Battery to Battery Charger

Sterling has continued to innovate in the DC/DC charging market and the newest range, the Saturn series, is the culmination of our market knowledge that we’ve accumulated over the years. Market-leading power, efficiency, and capabilities are the cornerstones of a product that we expect to exceed your expectations.

DC to DC Charger

Buck/Boost Technology

96-98% efficiency, offering you the best harvest from point A to point B and the coolest running, too. Fan cooling (on units 40A rated or above) and a metal chassis means we’ll be running at full power all day long.

Charge While Driving

When your engine is running, the Saturn charger will be charging your leisure battery at your chosen battery charge profile, using your alternator as the power source. The Saturn is even suitable for Euro-6, Euro-7, and Electric vehicles, in various configurations. It’s the best way of safely and intelligently charging a rear battery system when driving.

Bidirectional Charger

One of the most important features of the Saturn is actually what it does when you’re not driving. When you have excess charge available on your leisure battery from Solar or Shore Line Charging, the Saturn charger will automatically engage its reverse charge feature.

Simple Install

Positive input from your starter battery, positive output to your leisure batteries, and a common negative throughout. The only additionally required cable is going to be the ignition feed, and that’s only if you have a smart alternator, or a slightly low input voltage.

Euro 6 / 7 and Smart Alternator Compatible

Smart alternators pose a challenge to many DC/DC chargers, but our ability to be ignition controlled or even vibration controlled ensures that the Saturn runs whenever your key is turned, like you want it to.

Current Limiting + Lithium Suitable

The inherent current limiting nature of our Saturn units ensures predictable equipment and performance, charging within a current range that the batteries prefer, while preventing alternator overuse.

More Lithium Features

Reliable and controlled voltage output, live output modes (to wake a sleeping BMS), low-temperature output shutdowns (0°C), and two lithium-suitable charge presets.

6 Preset Charge Profiles + 1 Custom Profile via Remote

The Saturn series of chargers has 6 integrated presets suitable for a broad range of batteries. In case our presets don’t fit, the BBR remote allows for custom profile settings.

Cross Voltage Thresholds

The Saturn series opens up possibilities for 24V or even 48V leisure/domestic systems. Reverse charge engages at >13.8V in lithium settings and >13.6V in other settings.
