    Charging management board features:
    1. High-end technology MPPT solar maximum power tracking charge management chip, with turbulence, constant current, constant voltage charge management
    2. Adopt imported high frequency low conduction internal resistance double MOS tube, high current diode, high efficiency flat high power inductor, alloy current detection resistance
    3. Extra large aluminum heat sink at the bottom to ensure long-term stable operation at high currents
    4 high speed and efficient charging
    5. Dual status indicator, when the battery is not connected, the red light is always on, the red light is on when charging, and the green light is on

    Basic parameters:
    Input voltage: nominally about 18V solar panel (no-load 21V solar panel)
    Output Voltage: Nominal 12V (10.8 11.1V) Fully Charged Voltage 12.6V Lithium Battery 3 string lithium battery charge management
    Output current: maximum constant current 3A (charge current greater than 2A please add heat)
    Wiring method: pad
    IN+ input positive, IN- input negative (SOLAR)
    BAT+ battery positive, BA- battery negative
    Size: 31*45mm
    Solar Battery Maximum Power Point Tracking (MPPT)
    The maximum power point tracking (MPPT) of the solar cell is to ensure that the photovoltaic cell always outputs the maximum power in order to fully utilize the solar energy when the light intensity changes. In the general case, the MPPT function needs to be implemented with a switch mode DC-DC converter to maximize the product (output power) of the output voltage and the charging current.
    CN3722 adopts the switching step-down mode DC-DC conversion to realize the maximum power point tracking function of photovoltaic cells. Its input voltage can reach up to 28V, which is very suitable for applications with large difference between input voltage and battery voltage.
