I am currently designign a 4S2P Li-Ion battery pack. The cells I use are unprotected, so I want to use one of those BMS/Protection/Balance boards like this:
I want to include the charging in my project and all these boards talk about being "charging boards" and specifying a "charging voltage".
Do I assume correctly, that those boards do not implement proper CC/CV charging procedures?
If I want balanced charging, and my protection board provides balancing, would I be able to charge the pack by using a CC/CV circuit to apply a charging voltage to the entire pack?
I'm also thinking about not using balancing, since I have new identical cells.
