A battery has no such ability as push certain current through a load regardless what a load wants and loads generally have no such ability as suck a certain current regardless what a battery offers. The current is a result, the found balance between the voltage and resistances in the circuit.

We can construct control circuits which try to regulate the current, but they fail as soon as some basic laws of the electricity must be violated. For example many led light drivers try to keep a constant current current through a led chain. The led driver succeeds if it has enough voltage for the number of the leds. It fails if there are too much leds or other resistance.

ThoseThe most basic laws which cannot be violated are Ohms law, Kirchoff's laws and the energy principle. You should learn these if you try to calculate something about the electricity.

The situation is same in water supplying systems. There are no such systems in use which try to push say 2 liters/second. The system has certain pressure. You have not a faucet which unavoidably takes say 3 liters/second. You turn the faucet to have some resistance and the flow is the resulted balance between the pressure and flow resistance.

You can construct a controller which opens the faucet until the flow is 3 liters/second. It has a flow measurement sensor. Your controller fails if the water supplying system haven't enough pressure to push that much water/second through all the pipes between you and the pump station.

Voltage in a battery or pressure in the water supplying system can be so high that a breakdown occurs. But that's due a tendency to push a certain current or water flow only if there's some current or flow control system which can rise the voltage or pressure over the breakdown limit.
