Features of PACK

①Battery pack PACK requires batteries to have a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life).

②The cycle life of the battery pack PACK is lower than that of a single battery.

③Use under limited conditions (including charging, discharging current, charging method, temperature, etc.)

④The battery voltage and capacity of the lithium battery pack are greatly improved after the PACK is formed, and must be protected by charging equalization, temperature, voltage and overcurrent monitoring.

⑤The battery pack PACK must meet the voltage and capacity requirements of the design.
