$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).

A battery is comprised of at least one but possibly many such cells appropriately connected. Because the cell is where the actual action of storage and discharge takes place, …
How does the discharge rate of a 9V battery affect its performance? The discharge rate of a 9V battery refers to how quickly it loses its charge over time. A higher discharge rate means the battery will lose its charge faster. The discharge rate of a 9V battery can affect its performance by reducing its maximum current output and overall lifespan.
Batteries of the same type will often be rated by the amount of current they can output over time. For example, there are 1000mAh (milli-Amp Hour) and 2000mAh batteries. Nominal Cell Voltage - The average voltage a cell outputs when charged. The nominal voltage of a battery depends on the chemical reaction behind it.
A 6 volt battery might have a cell voltage of 2.2 volts and a 12 volt battery might have a cell voltage of 2.1 volts. This can however be fairly easy to read with a volt meter if one was to check. Matching amp hour ratings is …
For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.
Charging of battery: Example: Take 100 AH battery. If the applied Current is 10 Amperes, then it would be 100Ah/10A= 10 hrs approximately. It is an usual calculation. Discharging: Example: Battery AH X Battery Volt / Applied load.
Understanding the battery voltage lets you comprehend the ideal voltage to charge or discharge the battery. This Jackery guide reveals battery voltage charts of different batteries, such as lead-acid, AGM, lithium-ion, LiFePO4, and deep-cycle batteries. ... current, and voltage. Let''s see how different charging or discharging currents affect ...
Technically the minimum amount of voltage for charging will be anything above the current state of charge. But that''s probably not the answer you''re looking for, from Lithium-ion battery on Wikipedia:. Lithium-ion is charged at approximately 4.2 ± 0.05 V/cell except for "military long life" that uses 3.92 V to extend battery life.
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is ...
In fact making the battery pack have "higher voltage" actually limits the current it can produce, since the only way to make the pack voltage higher is to connect many battery cells in series, so the current has to go through all of those resistive series connections.
How long does it take for a 12 volt battery to discharge? The discharge time depends on the load current. For example, a 12V battery with a 10A load would discharge in 10 hours if the battery is rated at 100Ah. What is the discharge current of a 100Ah battery? The discharge current is the rate at which current flows out of the battery.

My advice is as follows. Your application does not require detailed calculations with motor specs. What you need to do is measure the current when your motor rotates under the load, which you choose. Then compare it with battery capacity. About voltage drop of battery, it does not draw more current when battery gets low on Voltage.

$begingroup$ @Matt, I really really hate people saying "its not the voltage, it is the current". Measure the 9V battery when on your toungue and you will find it is a lot less then 9V. Yes, we often rate things by their open circuit voltage, which does not tell you much, but it is the power that kills, that little 9V battery cannot deliver much.
