That depends entirely upon the type of motor. A car starting motor may take a few hundred Amps for the short period.
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
AWG #10 copper on a 30 amp breaker.
55/12=4.6
It is drawing .06 amps.
It would be at least 250 amps, maybe 300 amps.

Depends on how big the motor is. A stronger motor will draw more amps then a weaker or less efficient motor. For example a wiper motor draws far less then a starter motor.

Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
1 HP = 745.70 wattsPower (watts) = Current (amps) x VoltsSo if you use a 110 volt system, amps = 745.7/110 = 6.779 ampsIf you use a 220 volt system, amps = 745.7/220 = 3.389 ampsFor a 12 volt system, amps = 745.7/12 = 62.142 amps
Then you are trying to get more HP out of the motor that it can supply. Back off on the load that the motor is driving or put a bigger motor onto the load.
You would need to connect the two 12 volt batteries in series. That will give you 24 volts and the amps of one of the batteries. Voltage doubles and amps stay the same.

The electrical code book states that a 40 HP 230 volt three phase motor draws 104 amps. For that motor the wire must be rated for 131 amps, Non time delay fuses at 300 amps, time delay fuses at 175 amps or a 250 amp circuit breaker. When calculating wire sizes and motor protection the motor's full load amperage should be taken from the motor's nameplate.
