Whether you’re touring the country with the family in tow or just trying to keep your drinks icy cold between job sites, our DC-DC charger is one of the easiest ways to keep your batteries topped up without being tethered to a mains power supply. The charger can be used on a range of batteries including both 12V SLA, AGM, gel, calcium, and LiFePO4 systems. The DC-DC works by converting the power from your alternator into a charge voltage that carefully, but quickly, suits the status, and chemistry of your auxiliary battery all without affecting your vehicle’s starter battery. Designed to work on most vehicles, it’s compatible with either traditional or fixed/smart alternators and will feed up to 25A into your batteries per hour. There’s a dedicated Anderson-style plug coming from the unit for the inbuilt Maximum Power Point Tracking (MPPT) solar regulator function. The charger will use the power coming from the solar input when it detects it as either the only available power source, or if the solar input exceeds the power being produced by the vehicle. Able to regulate up to 25A, it’s able to handle solar up to 15% more efficiently than traditional Pulse Width Modulation (PWM) regulators. With a high heat tolerance, the charger can be mounted in most places including under the bonnet. This is particularly useful in vehicles that have the space for an additional battery in the engine bay, like in Landcruisers and Patrols, helping to not only reduce voltage drop but also free up some space in the back of the vehicle. The charger comes with three pre-wired Anderson-style plugs to make installation simple. The black plug connects directly to the auxiliary battery, the traditional grey plug is the dedicated solar input, whilst the three-pin Anderson plug can be used to quickly connect to the vehicle.
