Factors Affecting Safe Discharge Rates {#factors} Several factors influence the safe discharge rate of 18650 and 21700 battery packs: Cell Chemistry: Different lithium-ion chemistries (e.g., NMC, LFP, NCA) have varying discharge capabilities. Internal Resistance: Lower internal resistance allows for higher discharge rates with less heat generation.
Application Suitability: 18650 cells are often preferred in space-constrained applications, while 21700 cells excel in high-power scenarios. When designing a battery pack, consider these differences to choose the most appropriate cell type for your specific application and discharge requirements. 7.
The voltage of a 21700 battery typically varies between 3.6V to 3.7V when it’s in use. However, the voltage will fluctuate depending on its state of charge: Full Charge: The voltage will be around 4.2V. Nominal Voltage: The 3.7V is the average voltage at which most of the battery’s charge is used.
This means the battery is being discharged at twice its rated capacity per hour. To calculate the maximum safe discharge current: If a 21700 cell has a capacity of 4Ah and a maximum C-rate of 3C: For a battery pack, consider the configuration: For a 4S2P (4 series, 2 parallel) configuration of 3Ah cells with a 3C max rate:
