I am trying to add solar harvesting capability to my IoT device based on esp8266. I am using linear charge controller (MCP 73831) with solar input to charge a 500maH lipo battery.
An observation when the device is active (connected to a wifi AP) and solar input is available, the linear charger goes into CC mode even if the battery is fully charged. Possibly because esp8266 draws around 80-90mA of current on average during wifi connection process. (Solar charge current available is around 30-40 mA on average)
Is this safe? can this result in possible overcharging of the battery. More pointers on this will be highly appreciated.
