I am currently doing a project that involves object detection with the ESP32 and when it detects something, the NEMA 17 is supposed to turn to a specific angle.

However I want it all to be stored inside a container and moved around, thus I need the power sources to be portable.

I've seen online that powering an ESP32 with batteries is unreliable, so is it possible to simply power it with a 5v Powerbank?

And regarding the NEMA 17, I already bought a LiPo pack but I'm unsure how to use it safely, so I'm considering alternatives if possible.

For context I've only really had about 2 months of experience in electronics.
