D250SE 12V Battery Charger

The D250SE is a fully automatic 5-step charger designed to supply up to 20A of power to any 12V lead-acid or lithium service battery ranging from 40–300Ah. With selectable charge algorithms for AGM and lithium batteries, it can draw power from dual inputs including alternator, solar panels, or wind power. Once the service battery is fully charged, the D250SE automatically redirects maintenance charge to the starter battery, ensuring both batteries are always optimally powered. Its temperature sensor allows for efficient, weather-independent charging, while maintaining compatibility with smart ECU-controlled alternators.

Key Features:

• 20A fully automatic, temperature-compensated charging for 12V batteries (40–300Ah)
• Dual input: solar panel and alternator in parallel
• Smart alternator compatible
• Selectable lithium and lead-acid charge modes
• Solar panel regulator with Maximum Power Point Tracking (MPPT)
