Pi Flux - Battery Warning & Issue

Getting a low power warning on your Pi Flux? First, ensure the battery is fully charged, reboot the unit, and check if the warning persists.

*NOTE*All batteries are tested and used/charged for 1-2 hrs during setup and configuration. However, there is a percentage of batteries that arrive dead or not functional. We have a case open with the manufacturer, but for now, let us know if the battery is flashing all indicators when plugged in. This is a sign of a defctive battery.

To boot the unit simply press down the top button, pull up to turn off, it should make a click sound, may be harder to use when new. 

Charging and Ports

The Pi Flux has two USB-C ports with distinct functions:

• Left Side USB-C: Use this port for charging the keyboard. There is a switch next to it to turn the keyboard off. Not necessary as it turns off automatically.

• Right Side USB-C: Use this port for charging the larger Pi battery. Both the USB-C and USB-A ports can be used to charge other devices, such as your phone.

Powering the Unit

• To turn on the unit: Press down the top button until it locks. You should see lights through the left side vent.

• To turn off the unit: Simply pull the key ring up.

Additional Controls

• Double-press the bottom button to turn on the torchlight.

• Press the bottom button once to check the battery charge/ status.

Fixing the Power Warning on Raspberry Pi OS

If you see a low power warning, follow these steps to configure the PSU max current:

1. Open a terminal window in Raspberry Pi OS and execute the following command: sudo rpi-eeprom-config -e.

2. Add PSU_MAX_CURRENT=5000 at the end of the file.

3. Press Ctrl-O, then Enter, to save the changes.

4. Press Ctrl-X to exit the nano editor.

5. Reboot your Raspberry Pi 5 to make the change take effect.

• For other operating systems (e.g., Ubuntu): First, flash Raspberry Pi OS to complete the above settings, then re-flash your desired OS.

• For USB peripherals: If you are using USB peripherals that require power from the RPi5's USB port, prevent current limitation by enabling the following setting:

  • Add usb_max_current_enable=1 to the /boot/firmware/config.txt file.
