CALCULATED VS. ACTUAL SHORT CIRCUIT CURRENTS FOR VRLA
magnitude of discharge currents increase, the accuracy of the resistance and short circuit current values increase. In IEC896-2 "Stationary Lead-Acid Batteries, Part 2: Valve Regulated Types", the estimated short circuit current is obtained by discharging a battery at 4 times and 20 times its rated 10 hour discharge current (I10 at 25

What happens if a motor draws more amps than a battery can
Both scenarios are potentially hazardous. In the first case, the internal resistance in the battery will probably reduce the current sufficiently to prevent damage to the motor, but the battery may be damaged. In the second case, the internal battery resistance will not reduce the motor current sufficiently tp prevent damage to the motor.

But for example if a circuit designed for 12 volts having a resistance or 360 ohms and an expected current draw of 0.033 amps then it makes no difference if you use a little duracel 12v type 21/23 battery, your car battery; the limiting factor for battery discharge would be the circuit resistance and not the battery''s physical capability, chemistry, and electrical capacity.

maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.

Does a car battery dip a lot?
Yes, the voltage dips when a motor, such as a starter motor, draws more amps than the car battery can provide. However, this doesn't cause damage to the battery.
How long can a battery be discharged?
" Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
Can a smart battery run a motor without a fuses?
If it is a smart battery and the motor draws more amps than it can provide, some sort of overcurrent protection might kick in and the motor will not run. If it's a plain chemical battery with no fuses or BMS, the 20 amps figure likely is the battery's rated current.
What happens if you use an undersized battery?
Using a battery that is too small for the motor increases the chance that the battery may fail to supply the starting current, causing the motor (and any attached load) to not turn. This is similar to how a car may not start due to a weak battery.
Can a car battery get damaged?
Whether a battery gets damaged depends on several factors, primarily the heat generated in the motor and the battery. A motor drawing more amps than a battery can provide can generate excessive heat in the motor, which could potentially damage it. Vehicle batteries are rated for this situation. Other batteries may not be, which is why they have a short term max discharge rating (aka "CCA" cold cranking amps) and a continuous discharge rating.
What happens when a Li-ion battery is depleted?
When a Li-ion battery is depleted it undergoes a chemical process that ruins the battery below certain voltages. This is not related to the motor. However, if a motor draws more amps than a Li-ion battery can provide, the motor windings may get so hot that their insulation melts or the windings break open.
