What battery supply should I use for a small project?

[barkbomes9]

I'm creating a project that goes on the user's wrist, and I'm wondering what kind of battery supply I should use. It needs to be really small. I tried 2 CR2016 3V batteries, it was enough for the arduino to power and run code, but it wasn't enough for everything to function properly. I'm nervous about using Lipo Batteries because they are dangerous and can explode. Any suggestions for a small and safe battery supply?https://discord.software/ https://omegle.onl/ vshare

Hmm, maybe other types of coin batteries - for example the thicker CR2032 - they should have higher voltage and current. There are also rechargeable options for CR2032.
