JC3248W535 battery powered

I feel tempted to add a 2000-3000mAh 1.25 battery like this one (https://amzn.eu/d/06XciKaT) to my JC3248W535-based project to make it even more portable. The JC3248W535 itself has a dedicated battery port, i have seen mentions of it being used with a different JC3248W535-based project. Allthough I do not expect things like a charging display I wonder if the basics like running the controller and the TonexOne on battery and charging the battery might probably work out of the box. Any experiences?

A number of users have connected USB power banks (e.g. https://www.amazon.de/-/en/Powerbank-27000mAh-Schnellladefunktion-External-Smartphone/dp/B0DC6JFT94?th=1 )

These give out the 5v that the PCB needs (a bare battery is typically 2.7 to 4.2 volts, too low.
It also allows charging.

Some boards do have support for batteries and charging but I have not played with any of that side.

Thanks, I guess you are right: An external powerbank probably is the best solution. The battery connector was tempting at first but the necessary external battery switch would require some soldering directly on the board. And even though the controller itself appears to be able to run off 3.7V I am not so sure about the 5V/260mAh the TonexOne wants to draw from the USB-C port. An external powerbank is also much more cost effective. Final conclusion: Not worth the effort...
