ESP8266 Community Forum

I'm working on a little system that contains an ESP8266. I am looking for a way to power and recharge the system at the same time. I found a lithium battery charger module that I could use with a lithium battery and a DC-DC module to get a 5V tension. I want the battery to power the system and at the same time being recharged with usb. In many examples the battery is recharged out of the system.

Have you ever try that kind of module ? I don't know if it's the best solution.

Thanks
Catherine

When the board is receiving power via the USB connector, the battery charges and the ESP8266 works. When the USB power is disconnected, the ESP8266 switches to running from battery power.
