What happens if a battery pack is faulty?
If one cell in a series is faulty, cell matching is a challenge in an aging pack at the time of cell replacement. The new cell has a higher capacity than the others, which causes imbalance. That's why battery packs are commonly replaced in units.
How to repair a battery pack?
You can repair your battery pack by replacing this cell. The cells are connected in parallel to fulfill higher current capacity requirements if the device needs a higher current, but there is not enough space available for the battery.
Should I connect independent battery packs?
It is not recommended to connect independent battery packs but rather to put together a cell pack you need with an appropriate battery management system that can control all the cells in the pack. While it is possible for you to do what you are proposing, it is not a good idea.
When should a protection IC interrupt a battery?
The protection circuit/IC should interrupt the battery when any one of the cells is over or under voltage. I find most of the protection IC is to protect the cells connected in series, such as LV51131T. When connecting the cells in parallel, the way I can think of is to add multiple protection IC, such as DW01-P.
