1 Cell Lithium Battery Charging 3.7V 4.2V CN3791 MPPT Solar

Features:Solar maximum power point tracking (MPPT) is to ensure that the light intensity change, photovoltaic cells output maximum power, to make full use of solar energy. In general, need to use a switch mode DC - DC converter to realize MPPT function, keep the output voltage and charging current product maximize (output), Adopts the model of switch step-down DC - DC conversion way to realize tracking function of maximum power point of pv cells, the input voltage 9V/12V, very suitable for the application of the input voltage and battery voltage difference is bier. Charging management board features:1. The high-end technology MPPT solar maximum power tracking charging management , with a trickle, constant current, constant voltage charging management2. ed high frequency low conduction resistance double MOS tube, large current diode, efficient flat power inductor, alloy current sense resistor3. The bottom of the large aluminum heat sink, guarantee the stability of large current length of time and work4. High speed and efficient way of charging5. Double status indicator light, not the battery when the red light flashing green light normally on, red light when charging, auto stop when full of green light at the same time Specifications:Input voltage: 6V/9V/12VOutput voltage: 3.7 V nominal full of termination voltage of 4.2 V lithium battery series of lithium battery management3 a output current: the most it flowConnection mode: welding+ input IN the anode, the IN - input cathode (SOLAR)OUT + battery anode, the OUT - battery cathodeSize: 4.5x3.1cm/1.77x1.22inchQuantity: 1 PcNote: Due to the difference between different monitors, the picture may not reflect the actual color of the item.
