SAFETY CAUTIONS:

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.

Features at a glance:

Designed for Raspberry Pi series, compatible with Raspberry Pi 3 / 3B+ / 4B, etc.
I2C bus communication, monitoring the batteries voltage, current, power, and remaining capacity in real time
Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable
Onboard 5V regulator, up to 5A continuous output current, more sufficient power source for Raspberry Pi
5V USB output, convenient for powering other boards
Batteries warning indicators, easy to check if the battery is connected correctly
Comes with development resources and manual

Specifications:

Output voltage	5V	Charger	8.4V 2A
Control bus	I2C	Dimensions	56 × 85mm
Battery support	2x 18650 Li batteries (NOT included)	Mounting hole size	3.0mm

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

Pogo pins connector

Powering the Raspberry Pi via pogo pins, without using any GPIO resource,
compatible with Raspberry Pi 5 / 4B / 3B+, etc.

Connecting with Raspberry Pi 5

Connecting with Raspberry Pi 4B

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 shutdown the system by software, to avoid any data loss

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

Safe and stable circuit design

Protection circuits for over charge/discharge, over current, short circuit, and reverse
along with the equalizing charge feature, more safe and stable

5V USB Output as well

convenient for powering other boards

Battery warning indicators

easy to check if the battery is connected correctly
