کیت منبع تغذیه بدون وقفه UPS رزبری پای برای باتری لیتیومی

Description:
This is a power expansion Board especially designed for Raspberry Pi, which enables to use the Raspberry Pi with a moveable power source. It's more convenient to use external 3.7V Lithium battery.Support charge while discharge, it will not affect the output of UPS power supply when external power outage.
Two power modes: Outdoor portable model and Indoor UPS power supply mode:
As an outdoor portable power supply, the motherboard is powered by a lithium battery, and the maximum external power supply capacity is 5.1V, 2.5A.
As an indoor UPS power supply mode: MicroUSB plugs into a normal 5V,2A power adapter, and the external output interface(USB-A interface) can output a maximum of 5.1A, 3A
4+2LED to shows charger and discharger, battery power status.
Protect function, The external output port has a self-recovery fuse to prevent the raspberry pi from being burnt due to an external short circuit.
Two output modes, except for the regular output via USB port. At high currents, such as for high loads above 2.5A, the voltage drop across the USB cable is a problem that cannot be ignored. Therefore, we provide a 2.54mm header, which is welded at the Raspberry Pi GPIO 5V interface for direct power supply, to minimize the cable damaged and pressure drop.
