While a lithium-ion cell is a single battery unit, a battery pack combines multiple cells in series or parallel. The typical lifespan of lithium-ion batteries is around 300-1000 charge cycles. Voltage vs. Charging Relations The relation between voltage and the battery's charge is often overlooked, but it's important.
50% capacity in a lithium battery often correlates to approximately 3.6V to 3.7V per cell for most lithium-ion batteries. This voltage range represents the mid-point of the battery’s discharge cycle. What is the cutoff voltage for a 12V lithium-ion battery?
Lithium iron phosphate (LiFePO4) battery packs come in various voltage ranges, but they are all assembled by connecting basic cells in series or parallel. By connecting cells in series, different voltages can be obtained to meet different production needs.
Single lithium polymer (Li-Po) cells typically have a nominal voltage of 3.7 volts. When the voltage of this type of cell is charged to 4.2 volts, it is considered fully charged. During the battery discharge process, when the voltage drops to 3.27 volts, the battery is considered fully discharged.
A 2S lithium polymer (Li-Po) battery is typically composed of 2 cells connected in series, with a total nominal voltage of 7.4V. Charging to 8.4V indicates that the battery pack is fully charged, with each cell reaching 4.2V at this point. Discharging to 6.54V means that the battery pack has been fully discharged, with each cell at 3.27V.
Lithium-ion cells are widely used in PCs and cellular phones because of their high energy density and high voltage. While a lithium-ion cell is a single battery unit, a battery pack combines multiple cells in series or parallel. The typical lifespan of lithium-ion batteries is around 300-1000 charge cycles.
