Wiki,Tutorial,Program,Code,User Guide (Click here)


[] Do not include Raspberry Pi and Li battery


[] The UPS HAT (D) is an uninterruptible power supply (UPS) expansion board specially designed for the Raspberry Pi series. Onboard switching Li battery charging chip with path management, boost converter chip, and voltage/current monitoring chip. Supports simultaneous charging and discharging, and can provide stable 5V voltage output. Also, you can monitor the operating state of the batteries via the I2C interface. Supports displaying the battery level on the system, easy to check the battery's remaining capacity.


[] Adopts pogo pins connector design, compatible with Raspberry Pi 3 / 3B+ / 4B, etc.

[] Onboard Li battery charging chip, with dynamic path management, a more stable power supply.

[] Onboard boost converter chip for stable 5V power output.

[] I2C bus communication, monitoring the battery voltage, current, power, and remaining capacity in real-time.

[] Multi battery protection circuits: overcharge/discharge protection, over current protection, short circuit protection, more safe and stable.

[] Onboard LED indicators for monitoring the battery operating status.

[] Comes with online development resources and manuals.




[] BATTERY SUPPORT: 21700 rechargeable Li battery 3.6V (NOT included)

[] CHARGER SUPPORT: 5V, Micro USB interface

[] CURRENT CAPACITY: 5000mAh (Standard)

[] DIMENSIONS: 56 × 85mm



[] Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.

[] Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.

[] Do not mix use old batteries with new ones, avoid using batteries of different brands.

[] When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.

[] Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.

[] Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.

Uninterruptible Power

[] It is able to charge the batteries and provide power output at the same time from external power supply

[] Automatically switch over to batteries output if external power supply is unavailable, keeps the system running without any trouble

[] * for reference only, please refer to the Package Content for the detailed part list

Dynamic Path Management, More Stable Power Supply

[] When connected to the external power supply, the system will be powered and the battery will be charged at the same time, and the battery will be disconnected after being fully charged to avoid battery life damaging caused by frequent charging and discharging

[] When the external power supply is insufficient, the battery will provide power output together with the external power supply at the same time to ensure system normal operation

[] When the external power supply is connected, the system will keep running normally even when the battery fails or is taken out. And automatically switch over to batteries output if the external power supply is unavailable, keeps the system running without any trouble

Supports 21700 Large Capacity Li Battery, Longer Battery Life

[] Onboard Warning Indicators, Easy To Check If The Battery Is Connected Correctly

Pogo Pins Connector

[] Powering The Raspberry Pi Via Pogo Pins, Without Using Any GPIO Resource, Compatible With Raspberry Pi 3 / 3B+ / 4B, Etc.

Real Time Monitoring

[] Monitoring The Batteries Voltage, Current, Power, And Remaining Capacity Via I2C

[] When the voltage dips too low, it is possible to save files properly and then shut down the system by software, to avoid any data loss

[] for reference ONLY, the Raspberry Pi and Fan HAT are NOT included.

Supports Battery Level Display And Detecting Power Connection

[] Easy To Check The Battery Status In Real-Time, And Automatically Shutdown When The Battery Level Is Low. Onboard MCU Chip For Detecting Power Connection And Automatically Rebooting The Raspberry Pi

Onbaord USB Interaces

[] Adopts USB Type-C Interface For Charging And The USB Type-A Interface For 5V Power Output, Convenient For Powering Other Boards
