ESP32 on battery

Hi everyone.

I'm doing a project using ESP32DevKitC board and I d'like to know what is solution for battery supply and to provide an information about the low power battery.

I've seen this shield but it seems not very good.

Can you help me please ?

Thanks.

First; bear in mind this is an English forum, links to foreign web sites are not readable to most people in here.

The question your asking is, there are a number of ESP32 boards that are intended for battery operation, and include options for chnarging the battery, they are not difficult to find.

The ESP32DevKitC is an Expressif product I beleive, I presume they have a support forum for the products they sell.
