You can plug the 8.4V/2A charger provided for charging the batteries. Note that the 8.4V interface is the charging port.

Battery supported：18650 Li battery (NOT included).

Batteries warning indicators, easy to check if the battery is connected correctly.

5V USB output, convenient for powering other boards.

Onboard 5V regulator, up to 2.5A continuous output current.

Multi battery protection circuits: overcharge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable.

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

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards.

On a RPi4B those pins are electrically commoned with the power input contacts of the USB-C socket.UPS HAT For Raspberry Pi, 5V Uninterruptible Power Supply, Multi Battery Protection Circuits. You can power any RPI through those power pins.

The 40 pin GPIO header has both GPIOs and power pins. You cannot power a RPi though signal pins. Perhaps I'm misunderstanding terms being noted in these posts, but regardless just thought I'd be helpful and point out that it does work. Here's another thread on this forum where it also mentions it isn't possible through the GPIO pins. Second post in this thread specifically reads, "You can't power the Pi via the GPIO.

In this very thread and others (link below to another topic on this forum). After all, that's how the official PoE HAT does it.

It's common knowledge that the Pi 4B can be powered via the "GPIO" header if you supply a stable 5V with sufficient current to the correct pins. Thought I'd post this here since it took me several hours to figure out, and a lot of folks saying it wasn't possible with Pi 4B to direct power through the 40 Pin GPIO.
