Q: Why does the message "This power supply is not capable of supplying 5A" appear??
X120X series UPS shield can provide enough 5A power supply capacity;
Please set as follows:
Open the Teminal window based on Raspberry Pi OS and execute the following command:
sudo rpi-eeprom-config -e
Add PSU_MAX_CURRENT=5000 at the end of the file that reads like this:
Press Ctrl-O, then enter, to write the change to the file.
Press Ctrl-X to exit nano (the editor).
Reboot your Raspberry Pi 5 to make the change take effect.
Note: If you are using other OS like Ubuntu, please flash Raspberry Pi OS first, and then re-flash other OS such as Ubuntu etc after completing the above settings.
Q: How to disable auto power on feature on X1200?
A: When you connect an external power supply, the UPS board will automatically power on the Pi 5 motherboard while it starts charging, this feature is called auto power on, considering that some customers need to disable this feature, so we have also disclosed the following solution to disable it: please use a soldering iron to remove the resistor indicated by the arrow in the illustration.
PS: We don't think you need to remove the resistor to disable 'AUTO ON' function. Since there is an onboard switch, if you don't want AUTO ON, just press the switch to completely cut off the power.
WARNING: Please consider the following risks before removing this resistor:
- Do not operate if you are not a professional user
- The removal operation may damage the MCU, so please be careful with the operation.
- Once you remove this resistor by yourself, you will lose the warranty of this product. We no longer offer any warranty for this product.
- Once you remove this resistor, you can only turn on the power output by pressing the on-board switch.

Q: Why does the UPS shield continue to output power when PI 5 is turned off via press the on-board button?
A: The UPS shield provides enhanced power management features that intelligently monitor the power status of the Raspberry Pi 5 and automatically cut off power when the Pi is powered off. This helps optimize battery life by entering an ultra-low standby power consumption mode. It ensures efficient operation and maximizes the lifespan of the UPS battery.
To get the above features, check that the following settings are complete
Q: What battery is recommended for this ups shield
A: Please use high quality batteries from Samsung 35E 18650 lithium battery, Panasonic NCR18650B, Toshiba, etc. Do not use the battery with built-in protection circuit because it will limit the discharge current.
For the X1203 shield:
If using a lithium battery, the required voltage is 3.7V;
if using a battery pack, please make sure it is a parallel battery pack.
There are 2 XH2.54-2P battery connectors on board, it is recommended to use the same type of battery.
Q: Run sudo i2cdetect -y 1, can't find I2C address 0x36?
A:
1. Make sure you enable i2c interface, refer to How to enable I2C
2. The UPS connects to the Pi GPIO via pogo pins, If the I2C address (0x36) is not detected, Please clear the leads of pin 3 and pin 5 on the GPIO header from the bottom of the Raspberry Pi PCB and install again, and also check if the pogo pin of ups shield is in close contact with the pad position of PI 5(you can adjust the [pogo pin] position).
There won't be any other problems, it's this poor contact that's causing it.
Q. How do you disable the X1202 auto-shutdown when you use it standalone (not installed on a RPi5)?
A:
Q. X1203 UPS voltage drops / low voltage warning appears?
A:
1.Powering the X1203 via Type C connector with / without the batteries，Pls check if you still have the issue.
2.Please clear the test pad on the Pi's PCB bottom which is used for connecting the X1203 for 5V power delivery.
