What happens when you increase current to a DC motor?
Except that the motor is only a fixed resistance depending on it''s load. A motor with no load has lower resistance than a motor with a load, and a motor that is overloaded will stall out, having the highest resistance, drawing a stall current that (rule of thumb) is between 2 and 2.5 times the no-load current.

How do you match a motor to a battery? : r/Motors
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.
Electric battery
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices.

EV Motors Explained
Batteries are direct-current (DC) devices, so an EV''s power electronics include a DC-AC inverter to provide the stator with the AC current necessary to create the all-important variable RMF.
What is the minimum voltage that I can use to run a BLDC motor?
If the motor controller was to output the full battery voltage (48 V) to the motor at low speeds, the motor and/or controller would just melt down from the excessive current. Consequently every BLDC controller already does what you are asking; the full battery voltage is applied to the motor only at the maximum speed setting.
Electric Motor Power Rating
The battery power rating and energy capacity are major concerns for battery design. Because the battery pack is the only energy source coupled to the electric motor to generate the mechanical power, the power rating of the battery pack is straightforward and should be larger than or, at least, equal to the electric motor power rating:
Electric Motor Power Rating
In most mild hybrids, battery banks of 32 V–42 V are used, which is a much lower voltage level than that of full hybrids, mostly because of the 42 V standard introduced in the late 1990s.
charging
One of them is fully charged and the other zeroed. The empty battery will request almost all available current on firsts seconds, which in this case, near 1100A. (assuming a zeroed battery have a standard internal resistance of 5mohm. It can vary, and you can look for the battery datasheet). And it will kill the battery due to overheating.

Using a higher C rating lipo than recommended
The C rating does not change. All the C rating gives you is the maximum amount of constant current that you can draw from the battery before you cook it. If you overprop a 10 Amp motor, power it with a 20C battery and draw 20 Amps, the motor may flame-out but the battery will be OK.
The Horsepower Debate: Hybrids vs. Standard Cars
Despite having a much larger engine, when compared to the GS hybrid with its electric motor, the GS 460 only makes 3 more horsepower than the GS 450h. So that''s where the debate on horsepower between hybrid and standard cars comes from.
battery cca that is greater than what the vehicle specs require
A higher CCA just creates the ability for the battery to provide more starting amperage; it does not force more power than your starter should consume. More significant considerations are whether the battery fits into the battery tray. Larger CCA rated batteries may be in different size groups.

How does supplying a DC motor with lower than rated voltage …
They aren''t going to last very long, especially since a motor is an inductive load. You need relays rated for at least 14A inductive load. In practice a motor can draw a much larger current when starting up, than when running. So don''t even assume that the maximum current draw is 14A. Your little 7Ah battery isn''t going to last very long either.
