Hello,
I'm working on a battery powered device which needs 12V @ 6A, so I'm planning to use 3 li-ion cells in series. Each cell would be approximately 3000mAh. I'm planning to use rapid charge method, since 2-3h charing is not acceptable. So my question is - how to properly charge this pack, so that no one would burn their house in the process?
On the one hand everybody says that you need to balance cells, and on the other - pretty much every charge IC that I found is supposed to charge them in series. There seems to be not very much info about it, someone suggests that maybe it is ok for cells with protection circuit inside, or for charge at a low current (0.5-0.7C).
