Hello,
I'm building a bluetooth portable speaker. However, I have some questions about building my first 18650 battery pack. I have 4 pcs of Panasonic unprotected NCR18650B 18650 3.7V 3400mAh.[size=small]My goal is to build a 4s 18650 pack with these batteries, and the battery pack must: - be inside the portable speaker - Fully protected - Safe[/size]
My question is, how do I design this battery pack? I have a idea, but want to know if it is a good way to build it?:[size=small]I also have some others questions: During my searches on internet some people use balanced charge, is it necessary to it use in my case? If yes how? Do I need to use a power adapttor or lithium li-ion battery charger adaptor?[/size]
Thanks for your future help Cordially,
