The SmartPass is an energy management unit which controls and optimizes energy produced by alternators, solar cells, wind power or conventional AC/DC chargers, and distributes it to the battery banks or consumers which require energy, such as the deep cycle bank, bow thruster batteries, consumers, etc. Used together with a D250S DUAL, SmartPass provides optimal charging via CTEK’s unique staged charging cycle, which also protects your batteries.

It features an integrated ‘battery guard’ which protects deep cycle batteries from harmful total discharge and ensures that critical equipment such as radio, emergency lights and navigation systems always function. This charger is a fully automatic energy management system which can handle up to 80A for batteries of between 28-800Ah. The energy management system is IP65 classified (water jet and dust protected and approved for outdoor use) suitable for all types of 12V lead-acid batteries.

Designed to properly manage and distribute power, directing energy to where it is needed most, this ensures that service batteries are protected from being deeply discharged, providing batteries with an optimal service life and reducing the frequency and need for regular traditional charging. It has a sensor which senses the battery temperature and reduces charge current at high battery temperatures. The simplified installation eliminates the need for units with multiple outputs. The CTEK SmartPass converts a 110/230V charger with one output into a unit that serves both the service and starter battery.

The SmartPass has a 5 year Limited warranty
