<![CDATA[External Battery cap on Headers]]>Hello,
I have been trying to get a longer battery life with the M5StickC without a power bank through USB-C. I have been trying to use the BAT and GND pins on the headers. I opened one and realized the BAT pin is soldered the positive internal 80mAh battery wire. I tried connecting an external 400mAh lipo battery, so it would be connected in parallel to the internal one and for the little I know about these batteries I though they should work, but didn't. Does anyone know what I could do to make them work?

Thank you!

To increase the running time you should be appling power to the 5V< pin.

Is it possible to connect another lipo battery to the BAT pin?

I'm not entirely sure, but perhaps you could look at the design of beetlec, puppyc, bugc or the 8 servo hat as reference since they all use external lipo.
Not sure if the schematics are in here as I don't know how to open the schematics files https://github.com/m5stack/M5-Schematic

they are not there.

Would really like to know if it is possible to connect external lipo batteries to the BAT pin.

i'm wondering the same for my m5stickV

Still waiting for my m5stickC in the mail.
