Hi everyone :D

I'm working on a project and I need to power my arduino nano with a rechargeable battery because this project will be embedded.

I know that there is a lot of subject about it but I never found an answer for my problem.

I need a Lipo or Li -Ion battery, 7.4V or 11.1V, not too big. I heard that I will need a security circuit to avoid the battery to power while it is too low. I also need to have a circuit to charge it if possible.

I just want to avoid to use rechargeable AAA... but if I can't I will understand.

Do you know where Ican provide this kind of components?

Thanks you in advance for your help. Have a nice evening and sorry for my english, I'm French :D
