CTEK D250SE DC to DC Battery Charger - 12V, 20A
The CTEK D250SE – 12V 20A DC DC Battery Charger is a fully automatic, 5 step charger that supplies up to 20A of power to any 12V lead-acid or lithium* service battery from 40–300Ah. It has selectable charge algorithms for AGM and lithium* batteries and can use power through its dual input from alternator, solar panel and wind power. When the service battery is fully charged, the D250SE will automatically redirect maintenance charge power to the starter battery. The CTEK D250SE can maintain a stable output up to 20A to vehicles fitted with smart ECU controlled alternators and also has a temperature sensor for optimized charging, regardless of weather conditions. *12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
