The greater the current the larger the battery right
Electric Current. Electric current is defined to be the rate at which charge flows. A large current, such as that used to start a truck engine, moves a large amount of charge in a small time, whereas a small current, such as that used to operate a hand-held calculator, moves a small amount of charge over a long period of time. - Download [PDF]

How does more voltage (greater potential difference) mean more current ...
The greater the rate of charge transport (current) the greater the kinetic energy of the charge. A higher voltage means more work is done per unit charge by the voltage in moving it between the two points, thereby delivering more kinetic energy per unit charge to overcome resistance. That translates to higher current. Hope this helps.
