The “240A” of a lithium battery usually refers to the discharge current of the battery, not its capacity. However, when it comes to the capacity of lithium batteries, we usually see a numerical value in units of “AH” (ampere-hour) or “mAh” (milliampere-hour).
However, from the reference article 1, we can understand that although the “240A” directly given is not capacity, assuming that there is a 12V 240AH ternary lithium battery, the amount of electricity it can store can be calculated by multiplying the product of the rated voltage and capacity, that is, 11.1V (the rated voltage of ternary lithium 12V is usually 11.1V) * 240AH = 2.664KWH, which means that the battery can store about 2.664 kWh of electricity.
In summary:
The “240A” of lithium batteries refers to the discharge current, not the capacity.
The capacity of a battery is usually measured in units of “AH” or “mAh”.
A 12V 240AH ternary lithium battery can store about 2.664 kWh of power.
