The LITHIUM US is a cutting-edge, microprocessor-controlled charger specifically designed for recharging and maintaining Lithium-Iron (LiFePO4) batteries, guaranteeing peak performance and longevity. With a charging current of up to 4.3A, it is highly versatile, capable of charging LiFePO4 batteries from 5Ah to 60Ah and maintaining up to 120Ah.

Operation is simple—charging starts automatically upon connection, without needing to disconnect the battery from the vehicle. The LITHIUM US will reset any low voltage protection electronics (Battery Management System) at the beginning of the charge. Charging can be manually restarted anytime 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 determine if the LiFePO4 battery can accept and hold the charge, a unique maximization step to restore full capacity, and patented maintenance charging to ensure optimal performance even after long periods of inactivity. Splash-proof and dustproof (IP65), the LITHIUM US is safe and easy to use, protecting vehicle electronics with spark-free, reverse polarity protected, and short-circuit proof features. It also comes with a 5-year warranty from CTEK and a LIFETIME REPLACEMENT guarantee from us!
