What are the consequences of electrical current being greater than the battery
The electric potential (V_1) is higher than the electric potential at (V_2), and the voltage difference is negative (V = V_2 - V_1). As discussed in Electric Potential, an electrical field exists between the two potentials, which points from the higher potential to the lower potential.

19.1 Ohm''s law
Electric current is the rate at which electric charge moves. A large current, such as that used to start a truck engine, moves a large amount very quickly, whereas a small current, such as that used to operate a hand-held calculator, moves a small amount of charge more slowly. In equation form, electric current I is defined as
The possible consequences of an electric shock on the body
Nerves are tissue that offers very little resistance to the passage of an electric current. When nerves are affected by an electric shock, the consequences include pain, tingling, numbness, weakness or difficulty moving a limb. These effects may clear up with time or be permanent. Electric injury can also affect the central nervous system.

How much voltage/current is "dangerous"?
Shock hazards: Current, rather than voltage, is the most important variable in establishing the criterion for shock intensity. Three factors that determine the severity of electrical shock are: (1) quantity of current flowing through the body; (2) path of current through the body; and (3) duration of time that the current flows through the body.
Does amperage matter when charging a battery? (Solved).
Amperage is the measure of electrical current, and it is critical to understand when charging a battery. A higher amperage will result in a cooler, steady power supply and shorter charge time, while a lower amperage can cause the charger to overheat. ... We recommend always using a charger with an amperage that is equal to or greater than your ...
Physics Tutorial: Electric Current
If the two requirements of an electric circuit are met, then charge will flow through the external circuit. It is said that there is a current - a flow of charge. Using the word current in this context is to simply use it to say that something is happening in the wires - charge is moving. Yet current is a physical quantity that can be measured and expressed numerically.

Yes, parallel batteries "can" supply twice the current when the load is less than the ESR of the battery. ( As shown above, for short circuit current, it is twice.)

The easiest way to think of it is this: Current will only ever flow in a loop, even in very complex circuits you can always break it down into loops of current, if there is no path for current to return to its source, there will be no current flow. In your battery example, there is no return current path so no current will flow.
