The motor should have a voltage and power rating. You choose the same voltage (or lower) battery as your motor. The battery has to be capable of outputting more current than the motor needs at full load. Let's say you have a 12V 100W motor. You'll need a 12V battery, it should have a "C" rating, this is it's maximum current it can output safely.
The battery has to be capable of outputting more current than the motor needs at full load. Let's say you have a 12V 100W motor. You'll need a 12V battery, it should have a "C" rating, this is it's maximum current it can output safely. You multiply the capacity (measured in Ah) by the "C" (discharge) rating and you get it's maximum current.
The number of watts supplied by the car battery will depend on the battery capacity in ampere-hours and the battery’s voltage. The amount of power drawn from the battery in one hour is called watt hours and is the product of the two.
You multiply the maximum current by the battery voltage and you get the maximum power it can output safely. A 12V 5Ah battery with a "C" rating of 2 will be able to output a max. of 10A. 12V*10A=120w And in this case you would get a runtime of 30min.
If you could convert the single battery's voltage to motor voltage at 100% efficiency (& you cant) then current at current = Power/Volts = 8200W/3.2V =~ 2500 A.

Typically, most starter motors will require between 0.8kW to 3kW+ to start. The current drawn from the battery will be between 70A and 250A. This huge current draw will require a thick cable for the starter, and similarly for the jump start cable.

Battery for 12V dc motor : r/arduino
I would get a boost converter, and boost 5V from a USB power bank up to 12V for your motor. This way you can get 1A @ 12V from 2.4A @ 5V. Then, measure the actual current drawn by your motor when under load. It''s probably much less than 1A. From here you can calculate the size of your USB power bank, and whether you need 1 for each motor or not.
