Description
FULL 40A OUTPUT — NO HIGH-VOLTAGE DERATING — Unlike adjustable chargers with voltage-dependent current limits, the KNVAENEG 0-60V 0-40A LiFePO4 battery charger supports continuous 40A output at supported charging-voltage settings, including 14.6V, 29.2V, 43.8V and 58.4V. Raising the voltage does not reduce its rated maximum charging current. Manually select the voltage and current required by your battery; full-load operation requires a properly rated AC supply and a battery/BMS that accepts 40A. Current naturally tapers during the CV finishing stage.
ONE CHARGER FOR MULTIPLE LiFePO4 SYSTEMS — One adjustable charger covers compatible 12V/12.8V, 24V/25.6V, 36V/38.4V and 48V/51.2V LiFePO4 systems—no separate fixed-voltage charger is needed for each system. Set output voltage anywhere within the 0-60V range and charging current within 0-40A to match the manufacturer's instructions. Common charge-voltage examples include 14.6V, 29.2V, 43.8V and 58.4V. These are manual settings, not automatic battery-detection modes.
40A FAST CHARGING FOR HIGH-CAPACITY BATTERIES — Deliver up to 40A charging current for compatible high-capacity LiFePO4 batteries, including at higher charging voltages. At 40A in the CC stage, estimated full-charge times under suitable conditions are about 1.5-2 hours for 50Ah, 2.5-3 hours for 100Ah and 5-6 hours for 200Ah batteries. Estimates assume a compatible battery that permits 40A charging and will vary with state of charge, temperature, battery condition, BMS limits and the CV finishing stage.
FULL-COLOR REAL-TIME DISPLAY & DUAL COOLING FANS — The full-color digital display shows actual output voltage, charging current and power in real time, so you can monitor charging separately from the values you set. Front and rear cooling fans help manage heat during extended charging sessions. A durable metal housing and integrated carrying handle make this portable charger practical for garages, RV power systems, workshops, marine charging setups and off-grid solar storage.
CC/CV CHARGING, 0V ACTIVATION & SIX PROTECTIONS — The charging process includes pre-charge activation, constant-current charging and constant-voltage finishing; current tapers near full charge. The 0V Activation feature can help wake compatible sleeping LiFePO4 BMS systems ONLY with alligator clips connected directly to the battery terminals; Anderson and other connections do not activate this function. Built-in overvoltage, overcharge, overcurrent, overtemperature, short-circuit and reverse-polarity protection. Check polarity, charging limits and cable ratings; charge one battery at a time.
