The battery pack is the same set of battery numbers (either preferred) or individual battery cells. They can be configured in series, parallel or a mixture of both to produce the desired voltage, capacity, or power density. The term battery is often used in reference to radio-controlled hobby toys and battery electric vehicles.
Battery pack components include individual batteries or cells, and interconnects that provide electrical conductivity between the two. The rechargeable battery pack often contains a temperature sensor, which the battery charger uses to detect the end of charge. Interconnects are also found in batteries because they are the connecting parts of each cell, although the battery is most often only arranged in a string sequence.
When packets contain groups of cells in parallel there are different wiring configurations that take into account the electrical balance of circuits . The battery regulator is sometimes used to keep the voltage of each cell below its maximum value during charging, allowing the weaker battery to be fully charged, so that the entire packet returns to balance. Active balancing can also be performed by battery balancing devices that can drain energy from strong cells to weaker cells in real time for better balance. The balanced package lasts longer and provides better performance.
For inline packets, cells are selected and stacked with solder between them. The cells are pressed together and the current pulse generates heat to unite them and to weld all the internal connections to the cell.

Calculate the cost state
SOC, or charging status, equivalent to the fuel gauge for the battery. SOC can not be determined by simple voltage measurements, since the battery terminal voltage can remain constant until completely discharged. In some types of batteries, the electrolytic specific gravity may be related to charge status but this can not be measured on ordinary battery cells, and is not related to charge status in most battery types. Most of the SOC methods take into account the voltages and currents and temperatures and other aspects of the feeding and charge processes to calculate or decrease essentially in pre-determined packet capacity. A more complex charge load estimation system takes into account the Peukert effect that connects battery capacity to the discharge rate.

Benefits
The advantage of the battery is the ease with which it can be switched in or out of the device. This allows multiple packets to send long working time, freeing the device for continued use while filling out the removed packages separately.
Another advantage is the flexibility of their design and implementation, enabling the use of cheaper higher-production cells or batteries to be combined into packets for almost all applications.
At the end of the life of the product, the battery can be removed and recycled separately, thereby reducing the total volume of hazardous waste.
Disadvantages
Packages are often easier for end users to repair or change than batteries or cells that can not be serviced. While some may consider this to be an advantage, it is important to take safety precautions when serving batteries as they pose a potential chemical, electrical, and fire risk.
