Graham Cahill's Dual Battery Install Secrets

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.
