When connected to RPi5Bv1.0 I frequently have to separately push the power button on the RPI board itself in addition to the X729 power button. If not, I get only solid red LED on RPi5 but it remains in standby mode. Is this a timing fault of X729 for GPIOs (I boot from m.2 SSD, not SDCard)?

Hello,What power supply are you using? How do you power the X729 and RPi5? could you please provide a video or installation picture？ it will be very helpful to us to judge the problem. Please contact us by email info@geekworm.com. and tell us your order number.

If you use other HAT (M.2 SSD shield), please remove the Hat and only test X729+RPi5.

How is it possible to connect a external battery?

what specifications has "external battery"? (2-li-io cells in order or in parallel?)

will "external battery" be loaded via WideDC? with 3.000mA?

will "external battery" be checked for status (full, 50%, almost empty) and then reported via script?

is it possible to build an external battery myself? or are ic chips needed to ...do some stuff "inside" the "external battery"?

looking forward for a reply!

Hello, X729 can connect an external battery through the 4 positions in the figure, and the battery structure is parallel connection

Hi,

what specifications has "external battery"? (2-li-io cells in order or in parallel?)

==Normal 18650 battery

will "external battery" be loaded via WideDC? with 3.000mA? ==Of course, the external battery is charged also via wide range DC.

will "external battery" be checked for status (full, 50%, almost empty) and then reported via script?

==Of course.

is it possible to build an external battery myself? or are ic chips needed to ...do some stuff "inside" the "external battery"?

==Normal 18650 battery. I don't think you have to go DIY batteries yourself.
