Lithium-titanate (Li4Ti5O12) batteries typically have a voltage rating of around 2.4 to 2.5 volts per cell. This is lower compared to other lithium-ion battery chemistries like lithium-cobalt oxide (LiCoO2) or lithium-iron phosphate (LiFePO4), which usually have nominal voltages of around 3.6-3.7 volts per cell.
It's important to note that lithium-titanate batteries are known for their fast charging capabilities, long cycle life, and wide temperature range tolerance, which makes them suitable for applications where high power and durability are required, such as in electric vehicles and energy storage systems. However, their lower voltage per cell might require different configurations in certain applications to achieve desired voltage levels. Multiple cells can be connected in series or parallel to achieve the desired voltage and capacity for a given application.
