Battery to Smart battery charger in a dual battery application
The D250S DUAL charger obtains its energy from DC sources such as alternators, solar panels or wind power and optimises this power to meet the charging requirements of different battery banks.
The D250S DUAL is a fully automatic 5-stage charger that supplies 20A to 12V batteries of 40–300Ah. It obtains its energy from DC sources such as alternators, solar panels or wind power and optimizes this power to meet the charging requirements of different battery banks. The D250S DUAL automatically selects the best connected DC energy source (of 2) for the purpose and switches between them to achieve high efficiency multi-stage charging. It is suitable for all types of lead-acid batteries (Wet, MF, Gel, AGM). The charger is IP65 classified (water jet and dust protected and approved for outdoor use) and protects vehicle electronics. The charger comes with a 2-year warranty.
