A:Regarding the low voltage warning issue(Please refer to Q1 to check whether the connection is installed correctly):
* Please carefully check whether your hardware installation is secure and if the pogo pins are making proper contact. We have had cases where customers found that loose brass standoffs caused poor contact with the pogo pins, leading to the low voltage warning.
* It may be caused by an OS update. Please confirm whether you have recently updated the OS or if your OS system updates automatically.

QQ9: What battery is recommended for this ups UPS shield?
</div>
<div class="mw-collapsible-content">
If using a lithium battery, the required voltage is 3.7V;
if If using a battery packor battery holder, please make sure it is a parallel battery pack. '''Please use a high-quality battery holder with thick and durable connection cables. Using a low-quality battery holder with thin or poorly connected wires may cause the X1203 to malfunction or fail to operate as expected.''' 
There are 2 XH2.54-2P battery connectors on board, it is recommended to use the same type of battery.

Q14. Why does the RPI 5 lose power within a few seconds after pressing the power button on the X120x UPS?
</div>
<div class="mw-collapsible-content">
A:
 
'''Please note: If the UPS does not detect the RPi5, it will automatically shut down within 3 seconds. So you need to install the RPi 5 on the UPS and make sure that the RPi5 has good contact with the UPS's pogo pins.'''

Q15. Which product should I choose if I can’t connect to a Raspberry Pi via pogo pins?
</div>
<div class="mw-collapsible-content">
A:
 
For the X12-UPS series, we recommend the '''[[X1206]]''' – models from X1200 to X1205 do not support this usage. The X120- UPS series auto-powers off when no Raspberry Pi 5 is detected, while the X1206 can be set to "Always Power On" mode and keeps working even if the Raspberry Pi is shut down. Please refer to <span style="color:red">'''Interface ⑩_ALON'''</span> in the picture.

You can also consider the '''[[X-UPS1]]'''. It features a GPIO Pin-Connected standalone design with high flexibility for installation and adaptation (refer to the picture).
