60V battery means the battery voltage is 60V. Volt is the unit of voltage. The 48 volts, 60 volts and 72 volts we usually talk about all refer to the battery voltage of an electric vehicle. For example, electric vehicles use lead-acid batteries. The standard voltage of each battery is 12 volts, and the voltage of electric vehicles is 12 times that of the battery. If there are 4 batteries, the voltage of the electric car is 12 times 4, or 48 volts.
It should be noted that the 48V of lithium batteries for electric vehicles is not really 48V. Lithium batteries, such as lithium iron lead acid, typically have a voltage of 3.2 volts as the standard unit. But in order to unify the voltage of lead acid batteries, they are also called 48 volt lithium batteries and 60 volt lithium batteries.

1. The number of discharge cycles of electric vehicles is small: the daily power consumption of electric vehicles is recorded as one discharge cycle, while the number of discharge cycles of 60-volt electric vehicles is relatively small, and the service life of the battery is relatively long.
2. Battery type: Electric vehicle batteries are divided into lead-acid batteries and lithium batteries. The lifespan of different types of batteries is also different. The lifespan of lead-acid batteries is 3 years. The lifespan of 60 volt lithium batteries is 5 years.
