Supplying a Nano

Projects General Guidance
1

hi there,
hope you're all fine.

I'd like to know the best practices about supplying a Nano to make it autonomous.
I thought about to use a small battery (or more than one) but I'm hesitating because I'd like to provide to the users a system that works with more findable batteries.

any ideas? practices? experiences ?

best,

I'd like to know the best practices about supplying a Nano to make it autonomous.

The first question I'd ask is "for how long?"

I'll use it with a bluetooth module (argh, I guess it sucks power)

It must be on for 4 or 5 h maxi (2h would be great!)

Did you have any progress as of late? I am doing a project that will be using a bluetooth transmitter and trying to find the best battery that would last my device for almost 6 hours while not exeeding 1/2 and inch.
