The CTEK 120A Charging System is everything you need to power your adventure. This complete system includes:

D250SE
The D250SE is a fully automatic, five-step charger that supplies up to 20A of power to any 12V lead acid or lithium service battery from 40-300Ah. Includes selectable AGM and lithium batteries and can use power through dual input from the alternator, solar panels, or wind power. When the service battery is fully charged, the unit will automatically redirect maintenance charge power to the starter battery.

SMARTPASS 120S
SMARTPASS 120S is an energy power management unit with built-in under-voltage protection. It distributes, controls, and maximizes available energy from the alternator to power the service batteries and equipment. The SMARTPASS 120S separates critical equipment from non-critical equipment ensuring that radio, emergency lights, and navigation systems always have power.

System Monitor
The CTEK System Monitor unit continually monitors the battery voltage and current into and out of the battery, and calculates the state of charge together with the time remaining to charge or discharge the battery. The System Monitor gives you full visual control over your battery life so you know how many hours you can continue to use energy without running flat.
