I am new to electronics and just getting started with a project to make a BT speaker. I bought some quality protected 18650 Li-ion cells from Orbtronic. I would like to build a charger myself for these batteries using a 5V,3A wall adapter that I have.
Most people use the TP4056 to charge unprotected cells, which is fine, but
Do I need a TP4056 to charge my cells (one TP4056 per cell)?
If I don't need them, am I okay to hook up the 5V,3A wall adapter directly to the 18650 cells and rely on their protection circuit to charge them? Is this okay? It seems like the more dangerous of the 2 options.
I would appreciate any help or, better yet, any links you can provide.
