 It is a 3-series lithium battery charger. The solar cell maximum power point tracking (MPPT) is to ensure that the photovoltaic cell always outputs the maximum power when the light intensity changes to make full use of the solar energy. In general, it is necessary to use a switch-mode DC-DC converter to realize the MPPT function to keep the product of output voltage and charging current (output power) maximized.
 1).MPPT solar maximum power tracking charging management chip, with trickle, constant current, and constant voltage charging 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 resistor.
 3).The large aluminum heat sink at the bottom ensures long-term stable operation under high current.
 4).High-speed and efficient charging method.
 5).Equipped with dual battery status indicators to see the battery status.
