What is a BMS protection board of lithium battery?
The short-circuit current is the amount of current that flows through a battery when it is shorted out. For example, if you have a 12V battery with a 0.05-ohm resistor, its short-circuit current would be 240 amps (12 x 0.05 = 0.60A).
The short-circuit current of a battery will depend on its voltage, chemistry, size and internal structure. We can usually simplify this to a simple model of an ideal voltage source and an equivalent series resistance. It should be clear from the model that the voltage at the battery terminals will droop with increasing current.
