==Overview==
After more than 2 years, we update and release ups 2 based on [[Raspi UPS HAT Board | UPS1]]

==Features==
* Raspberry Pi standard HAT size, all components under the PCB board, and the use of 5mm high female socket, can reduce the thickness of the expansion board, easy to put into the shell. You can use the header to increase the height.
* Equipped with a custom long header (This is optional accessories)
* Supports dual power supply of TYPE-C and Mirco USB.
* Type-C power supply interface is compatible with a variety of fast charge standard DP2.0/QC3.0/QC2.0 (5V/3A), charging current is 1A ~ 3A configurable (default is 2A, short-circuit solder joint up to 3A)
* Up to maximum 3A current output;
* Long press power button 2 seconds to power on / off
* With 4 LED power indicator (short press power button to view battery capacity)
* Supports AUTO POWER ON function (need to select the AUTO UPS switch to ON)
* Use TI battery monitoring IC with patented Impedance Track algorithm
* Support I2C communication to read battery capacity, voltage, charge status and battery life (please refer to viewinfo.py)
* With charge and discharge protection and overheat protection
* The capacity of Lithium Battery '''MUST be more than 2500mAh''', you can use the more big capacity battery. PS: Voltage must be 3.7V.

==Packing List==
* 1 x UPS HAT 2 Board
