Yes, a battery pack can self-balance if it uses parallel cells. These cells naturally share charge through direct connections. My lead acid batteries (2S3P) are tired and I want to replace with LiFePO4. Was intending to just go with 2S for now. Shopping batteries, I saw one. . Whether you're working with solar systems, RV setups, electric vehicles, or DIY projects with more than one battery's system, understanding how to balance batteries can save you time, money, and a lot of headaches. This is NOT entirely true unless you have several days-weeks to waste. While it's true that cells connected in parallel will find their own natural balance, the same is not true for cells wired in series.
