Dc/DC Charger D250SE 20A Charging between batteries.

Powerful built-in charging when you’re on the move.
The D250SE, with its award-winning Swedish technology, allows dual inputs so you can enjoy your vehicle more with maximum battery capacity and is a perfect charger for vehicles without access to the electricity grid.
The D250SE is a fully automatic, 5-stage charger that delivers up to 20A of power to all 40 – 300Ah lead-acid 12V batteries, including wet, EFB, MF, Ca/Ca, AGM, Gel and even lithium
It has selectable charging voltages for AGM batteries and can use power through dual input from generators, solar panels and wind power. When the service battery is fully charged, the D250SE will automatically redirect the maintenance charge current to the starter battery. The D250SE can maintain a stable output of up to 20 A for vehicles equipped with intelligent ECU-controlled generators and also has a temperature sensor for optimised charging regardless of weather conditions.
