Features:
High-end technology MPPT solar maximum power tracking charging management chip, with trickle, constant current, and constant voltage charging management.
Adopt imported high frequency low conduction internal resistance double MOS tube, high current diode, high efficiency flat high power inductor, alloy current detection resistor.
The large aluminum heat sink at the bottom ensures long-term stable operation under high current.
High-speed and efficient charging method.
Dual status indicator lights, the red light flashes and green light is normally on when the battery is not connected; the red light is on when charging, it will stop when it is full and the green light is on at the same time.
