The Smartpass 120S is compatible with Lithium Batteries.

Available to work in tandem with the CTEK D250SA Dual 20A Charger for the ultimate 140A power management charger.

SmartPass is a total energy regulator for energy production, usage and storage in any 12V DC system.

SmartPass allows energy produced from solar, wind, AC chargers and alternators to be synchronised to maximise output and minimise charge time.

The energy is then able to be distributed to different battery banks and/or equipment such as lights and navigational systems that need additional energy supply, while ensuring the battery remains fully charged.

Smartpass makes sure that all of your applications have the power they need, when they need it.
