CTEK Lithium US Battery Charger

The Lithium US is an advanced microprocessor controlled charger specially designed to recharge and maintain the cells of Lithium-Iron (LiFePO4) batteries, maximizing their performance and lifespan. With up to 4.3A of charge current available the Lithium US is extremely flexible and will charge LiFePO4 batteries from 5Ah to 60Ah and maintain up to 120Ah.

The operation is simple and charging will commence upon connection. With no need to disconnect the battery from the vehicle, at charge start the Lithium US will automatically reset any low voltage protection electronics (Battery Management System) fitted. Charging can be restarted manually at any time using the Reset button.

The CTEK Lithium US is a fully automatic 'connect and forget' charger with 8 charging steps including a testing sequence to show if the LiFePO4 battery can take and retain the charge, a unique maximization step to restore full capacity, and patented maintenance charging to ensure maximum performance even after months of inactivity. Splash-proof and dustproof (IP65), it is easy and safe to use, protects vehicle electronics, is spark-free, is reverse polarity protected and short circuit proof. The Lithium US features a 5-year warranty.
