The like-new DC to DC chargers were purchased by customers who mistakenly or incompatible bought for their applications. We assure you that they are thoroughly checked and tested before delivery. Our like-new chargers come with the same 2-year warranty as our new one.
【Compatibility】Multiple Options For Charging 12V Batteries. Fit for?12V Lithium, Gel, AGM, and Calcium batteries and allows the batteries to be charged 100%. Also, it can activate the dead lithium batteries at low voltage.
【Max. 600W Solar Input & 40A Current Output】Equipped with an ACC wire, a solar input terminal, a DC input terminal, and an output terminal to enhance the operational efficiency of the solar, alternator, starting battery, and service battery.
【Intelligent Charging Protection】Overvoltage input protection, output reverse connection protection, battery overvoltage protection, over temperature protection, charging timeout protection, and BMS protection (for LFP battery).
【Easily Operating】Simple and straightforward operation instructions with LED indicator and operation buttons, users only need to choose the suitable battery type for your battery, then let the DC-DC charger do the charging.
【Reverse Charging】When the starting battery voltage is between 3-12V and the living battery voltage is greater than 12.5V, press and hold "REVERSE CHARGE" for 3 seconds to start reverse charging. It is recommended to start the battery when the voltage is greater than 13V and exit reverse charging when the charging current is less than 10A or the voltage of the domestic battery is less than 11V.
Note: Use the included screws (Φ15/64'' [6mm], 15/32'' [12mm]) for secure mounting to prevent installation failure or product damage.
