If I have a 16S 280Ah LiFePO4 pack where I have already top-balanced the cells, and it's now in use, then later on I want to add another 16S 280Ah pack (cells also top balanced), how do I make sure the two packs are balanced? It says that two of them in parallel will eventually balance, but I was thinking of "getting them close" by fully charging both packs individually then connect them in parallel.
Assuming cells within each pack is top-balanced:
1. Day one, fully charge Pack 1. Then disconnect (yes, it will be "stored" but maybe for a day or two at most, at full charge);
2. Day two, fully charge Pack 2. When it's fully charged, I can parallel connect pack 1 to the busbars.
In theory, both packs should be closed to balanced?
Finally, what if I wanted to add another pack, but different Ah (say, a 16S 200Ah battery pack whose cells are already top balanced). Can I just fully charge all three packs individually then connect them in parallel to the busbar?
