<![CDATA[Battery Bottom2 does not charge from M5GO/FIRE Battery Bottom Charging Base]]>Hello
I am having this problem that the bottom2 battery does not charge from the base. It would charge from the top port on the M5core2 but not from the charging base. Even the charging led does not light when the usb C cable is inserted at the base.
I tried opening a query with M5stack site but they only replied once to check the led and then nothing.
Please help!
Thank you
ioannis

thank you for reporting back. I am glad to hear you got it working.

And sorry you had to sort out a not so well assembled Battery Bottom2.

Thanks
Felix

Does anybody knows how to check if the M5core2 is connected to the bottom2 base power with a code?

thank you for your answer and concern.
I did open the bottom by removing the circuits screws.
The problem was that on of battery wires was caught between the board and the plastic and was creating the problem. everything now ok!
Thanks everybody for the help

you gave me an idea.
I opened it and checked the contacts- on the inside of the bottom2 - they do not contact the pins of the base. also the board seems elevated in this area. I guess something did not go well in assembling. IMG_9414.jpg

I have done all that. power is ok on the pins and they are new, just bought them so I guess contact is good.

neither red or green LED light up and also I wrote a small routine to check just to make sure.
It is definitely not charging!

I'd say if you place just the Battery Bottom2 (without M5Core2 stacked) onto the Battery Bottom Charging Base and neither red or green LED light up then something's faulty.

I tested the above setup and while the battery is being charged the red LED lights up and when the battery is full the green LED is on.

If that is not the case in you setup then you could check if the pins labelled 5 V and GND on the Battery Bottom Charging Base actually deliver the 5 V from the USB-C charger. Next is checking if the pins make good contact with the Battery Bottom2.

Thanks
Felix
