Battery protection packs can be divided into two categories. The first category is the Protection Circuit Module (PCM) it is also known as Protection Circuit Board or (PCB), And the other type is the Battery Management System (BMS). In the lithium battery, the battery management system is an essential part of it.
The battery unit is a lithium-ion soft pack battery model AEC653440, rated voltage: 4.2V, rated capacity: 900mAh (from AEC). The battery protection board is responsible for the overcharge, overdischarge, and overcurrent protection of the battery, and has the thermistor to detect the battery temperature.
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.

Each protection IC connects to a single cell and adding diode on each branch. Therefore there will be two identical protection IC on the board. However, by searching from the web, it seems nobody is using this method. I would like to ask what is the normal or correct practice for this purpose?
Yes and you can do this, because all the batteries which are physically hard-connected in parallel always have the same voltage, due to their parallel connection. To protect cells in parallel, you put a fuse in series with each cell.
