How to power the Arduino with a LiPo 3.7v battery?

Hello! I have a project with an Arduino Nano and Nrf24l01, for which I need your autonomy to be quite long, my project consumes around 150mah. Investigating I found out about the Lipo batteries, what happens is that the Arduino works with 5v and the batteries that are on the market are 3.7v, I also understand that they are somewhat dangerous. So, I would like to know if there is a cheap but safe voltage lifter, and a charging module to recharge the battery without having to remove it from its housing at a good price? or if someone knows another way to give the Arduino good autonomy it would be excellent!

If I manage to perfect the project I would like to do market tests to market it, that's why I need good security regarding its battery. Thank you.

Yes, ICs and modules do exist to do what you want. They are easy to find. Tell us where in the world you are if you need help finding a company that will ship to you.
