There are complete functions that can be applied directly.
Variety of species. There are many PACKs that can implement the same application need.
The battery pack requires the battery to have a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life).
The cycle life of a battery pack is lower than that of a single cell.
Use under limited conditions (including charging, discharging current, charging method, temperature, humidity conditions, vibration, stress, etc.)
The lithium battery pack protection board requires a charge equalization function.
High-voltage, high-current battery packs (such as electric vehicle batteries, energy storage systems) require communication buses such as battery management systems (BMS), CAN, and RS485.
The battery pack has higher requirements on the charger, and some requirements communicate with the BMS. The purpose is to make each battery work normally, fully utilize the energy stored in the battery, and ensure safe and reliable use.
