Sterling Power's revised Saturn range of Battery-To-Battery (DC-DC) chargers have been completely re-designed to make them simpler to use.

Sterling Power's revised Saturn range of Battery-To-Battery (DC-DC) chargers have been completely re-designed to make them simpler to use, more compact and easier to install, with a minimal amount of setup. They provide all the features of the previous generation but in a much more user-friendly package.

Compatible with both 'smart' and standard alternators, this 70A battery-to-battery charger is powered from your vehicle's alternator and delivers the correct charging voltage for your lead-acid or lithium battery. This new model features a vibration sensing mode, meaning that the charger will begin operating when the internal accelerometer detects vehicle movement. This eliminates the need to run a cable to supply an ignition or D+ alternator signal as is required on some other DC-DC chargers. An ignition feed option is still available should the vibration sensing not be suitable for your particular application.

This 70A model also features a bi-directional or 'reverse charging' feature whereby surplus current supplied to your leisure/house battery is passed to the starter battery to charge and maintain it. This is ideal when you are charging your leisure battery from shore/grid, solar, wind or generator power, and ensures that your starter battery is always kept in optimum condition.

The charger comes with a temperature sensor (optional fitment) that allows for temperature voltage compensation for lead-acid batteries, 0°C trip for lithium charging and high temperature trip protection. This unit also features a lithium battery BMS 'wake-up' function to enable your lithium battery to start accepting a charge if the BMS has put it into shut-down mode due to over-discharge.

An optional remote display not only allows you turn the unit on or off remotely, it also provides several additional advanced features such as custom charging profiles, current reduction and charging current and voltage display.

Sterling recommends connecting using 16mm² cable and 80A fuses.
