The ideal battery, in a short circuit with 0 Ω resistance, would be able to supply an infinite amount of current. The real battery, on the other hand, can only supply 50 amps (10 volts / 0.2 Ω) to a short circuit of 0 Ω resistance, due to its internal resistance. The chemical reaction inside the cell may still be providing exactly 10 volts
The wiring to a high current battery, like a car battery for instance, will invariably be protected by a fuse, which opens in the event of a short circuit. The wiring to a low current battery may not need protection, if the short-circuit current is low enough for any practical wire. Given this, there may be some sense, hinted at in your

What is a Short Circuit Current? Short circuit current is the maximum amount of current that flows through a power system during the fault occurrence. The short circuit current depends on factors like voltage, total impedance and the type of fault.The short circuit current is represented by I sc..

The short circuit current of a battery can be estimated using Ohm’s Law, which states that Current (I) equals Voltage (V) divided by Resistance (R). In the case of a short circuit, the resistance is extremely low, nearly zero. So, the formula simplifies to: Short Circuit Current (I) ≈ Voltage (V) / 0
A battery short circuit occurs when there is a low-resistance or no-resistance path between the battery’s positive and negative terminals, leading to excessive current flow. The short circuit current in a battery can vary widely depending on the battery type, capacity, and internal resistance. It can range from tens to hundreds of amperes.
For large batteries such as those used in Power Stations, short circuit currents may exceed 40k amperes. Even when the battery is not fully charged, the short circuit current is very similar to the published value because the internal resistance does not vary substantially until the cell approaches fully discharged.
Short circuit current is the maximum amount of current that flows through a power system during the fault occurrence. The short circuit current depends on factors like voltage, total impedance and the type of fault. The short circuit current is represented by Isc.
