Recommended battery &quot;ZMI 20000mAh PD battery&quot; not working on LattePanda Delta
I have purchased the battery recommended on this page:
https://www.amazon.com/ZMI-Pixelbook-Ni ... 468&sr=8-1
I charged the battery all the way, plug it in to the USB-c port on the LattePanda and absolutely nothing happens . My Lattepanda Delta does work as I am able to plug it in using the provided PD adapter. Can someone let me know what I am doing wrong here?
Also, it is recommended to use a Lipo battery "JST 4p DC Input Connector". Can someone recommend a battery?
