  • Product information
  • The advanced 3-stage charging process adapts charging to the battery's requirements and helps improve energy management and battery health. With a 40 A charging current, it is particularly suitable for motorhomes, caravans, boats and other vehicles with higher energy demands.

    The charger works with both traditional and smart alternators and protects the vehicle's electrical system through controlled charging. It achieves charging efficiency of up to 94% and uses advanced charging logic to optimise energy flow.

    Bluetooth is available as an option, allowing the system to be monitored and settings adjusted through a compatible app. The included battery temperature sensor provides real-time information and helps the charger adjust charging parameters according to battery temperature.

    At high temperatures, the charger automatically reduces output power to maintain safe and stable operation. Natural cooling also keeps the noise level at approximately 30 dB.

    The compact and corrosion-resistant construction makes the charger suitable for installation in smaller spaces and damp marine environments.
