If it is determined to be 200A, it means that the maximum operating current is 200A. If it is AH, a 200ah lithium battery is equivalent to about 2.4 kWh.
ah is one of the indicators that reflects the battery capacity. ah is the ampere-hour, which is the capacity of the battery and is defined as the discharge time based on the specified current. For batteries of the same voltage, the larger the ah number, the larger the battery capacity. Batteries with the same amp-hour capacity have higher voltages and larger capacities. Battery capacity is usually expressed in terms of voltage and amp hours. For example, 24V 10Ah represents the unit of energy storage capacity, that is, when the voltage is 24V, the battery discharge current is 1A and can be discharged continuously for 10 hours.
