Description
Battery monitoring
The project about not just charging a Li-Po battery but also about monitoring it by using esp-12s which is send the percentage through a url that will be generated from esp-12s. This microchip could be connected to your own WiFi.You can power it through the usb OR from power generator (5V).You can also use this circuit as a buck converter if u need 3.3v for ur project, just hook up the usb connector and there is one header pin which gives you 3.3v:).
