Q. What is the maximum capacity in mAh and current rating allowed for the batteries: How to disable '''auto power on''' feature on [[X1200]]?
</div>
<div class="mw-collapsible-content">
A: The battery capacity is generally less than 20000mAhWhen you connect an external power supply, and the maximum UPS board will automatically power on the Pi 5 motherboard while it starts charging current , this feature is 3Acalled '''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.

Q: Why does the UPS shield continue to output power when PI 5 is turned off via press the on-board button?
</div>
<div class="mw-collapsible-content">
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'''

Q1: Run <code>sudo i2cdetect -y 1</code>, can't find I2C address 0x36?
</div>
<div class="mw-collapsible-content">
A:
1. Make sure you enable i2c interface, refer to How to enable I2C
2. Please check if the pogp pin of [[X1202]] or other ups shield [[X1200]] /[[X1201]] is in close contact with the pad position of PI 5.
There won't be any other problems, it's this poor contact that's causing it.
