CTEK Dual Input DC to DC Smart Battery Charger D250SE 12V 20A 40-315

The CTEK D250ESE (item no. 40-315) is a fully automatic 5 stage charger that can supply up to 20A of power to any 12V lead-acid or lithium service battery between 40 & 300Ah. It allows you to fully maximise the usage of your battery charger and generate power while away from mains power, simply by drawing on the excess power generated by your vehicle's alternator, or by the optional extras of a compatible solar panel, or from wind power.

It is compatible with modern vehicles with smart ECU-controlled alternators and has an in-built temperature sensor to keep it (and your vehicle) safe from potentially dangerous heat build up during operation. Compatible with SmartPass120 and SmartPass120S.
