D250SE

The CTEK D250SE is designed to deliver 20A of power to charge, condition, and maintain any 12V service battery while on the move. It's compatible with smart alternators and its dual input capability allows it to draw power from a solar source. The D250SE features a built-in temperature sensor that compensates for hot or cold conditions and has three charging modes: normal (14.4V), AGM (14.7V), and lithium (12V LiFePO4). The battery charger also includes an input for connecting solar panels without the need for a regulator. The D250SE will still operate when there is low alternator output and maintain a stable output of up to 20A to charge the battery.
