I'm working on a project where I need to power my nodemcu with an external battery and I have three (electrical magnet 5vdc) connected to the nodemcu which I will control (on/off).
So I was thinking to have two independent power sources, one for the nodemcu (which consists of 2 Li-Ion Single Cell Battery), and one for components which they will get their power from an independent power source as well but the signal from the nodemcu.
My Questions:
1- Can I power the nodemcu with 2 Li-Ion Single Cell Battery (series connection) ?
2-what is the voltage and current needed for the (electrical magnet 5vdc) ? and can I use the Li-Ion Single Cell Battery too as the power source?
Components used:

Thanks in advance!
