(replaced D250SA 40-256)

  • 20A fully automatic temperature compensated charging for batteries from 40-300AH while you’re on the move
  • Dual input (solar and alternator in parallel)
  • Smart alternator compatible
  • Selectable lithium* and lead-acid mode

The D250SE 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 the 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 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.
