Hi, I tested the X728 to check if it has issue or not, as suggested in the Q&A - Q: Why Raspberry Pi is randomly rebooting all the time?

A: You can follow the steps to test if the X728 issue:

"Take the X728 off from the Raspberry Pi, remove all the batteries, power supply, and all jumper caps. Then connect the battery or power supply, press the blue power button on X728, the blue LED should be on, and then press and hold the power button for more than 8 seconds, the blue LED should be off.(These steps indicate that the X728 has no issue.)"

The X728 does not light up when connected without batteries. I thought I would be able to use the board even without batteries attached to power the PI5.

Also, when connecting the board to the PI5, with 2 batteries fully charged, the ACFAIL red led is on. Why is that?
