Battery-powered motor applications need careful design work to match motor performance and power-consumption profiles to the battery type. Optimal motor and battery pairing relies on the selection of an efficient motor as well as a battery with the appropriate capacity, cost, size, maintainability, and discharge duration and curve.
Generally, for a higher-power motor, a higher voltage is preferable. The selection of battery parameters is based on the range required for the vehicle and the capacity to provide peak discharge current and the duration for the peak current. Battery capacity (Ah or KWh) = (Mileage Requirement / Avg speed) x Avg current or power consumption.
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. (!!!!) . 10 cells in series give you 10 x the run time (30+ minutes) at 1/10th the current (250A) and you are beginning to get realistic. Beginning. ...
Getting a 72v battery and a 48v motor will likely fry your electronics located in the motors controller. Using too low of a voltage will not give enough voltage to even register in the controller and you will not be able to power it up. Some motors have a variable voltage they can run off and are usually clearly marked.
Matching your motor voltage and your battery voltage cannot be understated if you want your setup to even work, let alone cause serious damage. If your motor is rated at 36v, get a 36v battery and so on. Getting a 72v battery and a 48v motor will likely fry your electronics located in the motors controller.
The maximum current output needs to be at least 11.5 A. The load requires 24 V, so that should be the battery voltage. 7.5 A for 20 minutes comes out to 2.5 Ah. Let's say you want the battery to run down to no less than half full, so you need at least a 5 Ah battery. Two 12 V sealed lead-acid batteries of 5 Ah capacity or more would do fine.

The voltage should be chosen to match the power requirement of the vehicle at the required top speed. For example most DC motorbike conversions will require a minimum voltage of approximately 72V to be able to travel at 60+mph (100km/h) while a pick-up conversion would most likely require 144V to maintain the same speed.
