User Manual


Q1: Run sudo i2cdetect -y 1, can't find I2C address 0x36?


1. Make sure you enable i2c interface, refer to How to enable I2C

2. Please check if the pogp pin of X1202 is in close contact with the pad position of PI 5.

You can try to loosen the screws and align the pogo pin position before fixing the PI 5 motherboard.


Q2: What battery is recommended for X1202?


Pls use high quality batteries from PANPASONIC, Toshiba, etc.

Do not use the battery with built-in protection circuit.

Can you disable auto-boot if you plug power in? In some situation you do not want to boot only charge.

Hardware or software modification needed?

What happens, if I connect a USB C power supply that does not provide 5V 5A but for example 5V 3A.

Will the UPS use the batteries to make up for the missing power? Is it possible to charge the UPS with 5V 3A when the PI is turned off?

Thank you

Hi,When the load is heavy and the USB-C power supply is insufficient, the UPS will draw power from the battery. But if the USB-C power supply does not have overcurrent protection, it may be damaged. It is recommended to use 5V 5A power supply.

Manual says "Note: the voltage range must be 3.00~4.10vdc." 18650's can go down to 2.5V per cell. Can the minimum be 2.5-2.7V or is 3.0V min a hardware limitation?

After using the USB C port on the x1202 I heard the board making small ticking noises. After I pulled the plug the entire unit lost power. Is the USB C port not the preferred port?
