1011 12V 17A Lithium Ion Battery Charger is purpose built for Lithium Pros 12V Lithium Ion Racing and 12V Marine batteries. It is a light weight, high frequency type charger for charging 12V batteries made with Lithium Iron Phosphate cells. The 17A of output typically recharges Lithium Pros 12V Lithium Ion batteries with ease. (Actual recharge time varies by specific application and energy consumed.) High frequency chargers like the 1011 12V 17A Lithium Ion Battery Charger offer very consistent and smooth output voltage extending the life of your battery. It is 3 lbs and connects to the battery with alligator clips. The 1011 12V 17A Lithium Ion Battery Charger is fully automatic and fan cooled. Two LEDs show the simple status of the charger. The first status LED is red when input power is present. The second status LED is orange while charging and green when charging is complete and charging has stopped. In addition, the LCD display will read “End” when the charge cycle completes in a normal manner. “End” in LCD display tells you that the battery reached normal “fully charged” voltage and that the current acceptance rate dropped to less than 900mA in a normal amount of time. It features an LCD display with a wealth of battery status information. Battery voltage, charging amperage, State of Charge, Amp-hours charged, time on the charger, and more can all be viewed from the LCD display. This 1011 12V 17A Lithium Ion Battery Charger is universal voltage meaning that it accepts anything from 110VAC~240VAC @ 50~60Hz. (USA power cords included.) It is fused protected with a 6.3A 5mm x 20mm fuse installed.
