Parallel Pack – In a battery pack, cells are connected in a parallel system to enhance the capacity. Here, the positive and negative terminals are connected (either using a common conductor or to themselves). The battery pack is simply the total sum of capacity from all the cells. On the other hand, the pack voltage refers to the voltage of one of these cells.

A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it.
Circuitry in a battery pack, such as a gas gauge, needs to measure the battery-cell stack voltage at all times. This drives the decision to place the Li-ion protector FETs between the ground connection of the battery electronics and the negative pack terminal. This decision creates two design issues that can exist when the Li-ion protector FETs
