Solar USB Charger - How to use battery and charge simultaneously ? Answered

I have been trying to find a way to continuously run and ESP board off of a battery and recharge the battery using only solar panels. Is this possible? I am able to charge my phone while using it so I would imagine it is possible.

Yep, both of the solar charging circuits in this class will run the LOAD output and charge the battery simultaneously if enough power is coming in from the solar panel! The ESP8266 can draw a lot of current when it's on, which is why its deep sleep mode is used in the soil monitoring code.
