Assuming your load is a resistor and you do not change the original value of your resistor (i.e. 2.5Ω), then you would have to increase the voltage of the circuit to 20V to increase current in the circuit to 8A (20V/2.5Ω).

The main difference in voltage and current behavior between series and parallel connections is how they affect the total voltage and total current. Series connections increase the total voltage and keep the current constant, while parallel connections increase the total current and keep the voltage constant.

It is also noticed that, the efficiency of the battery sharply increases when the charging current surpasses the discharge current, it is explained using Peukert’s law which states that, “As the rate of discharge of the battery increases, the battery's available capacity decreases”.
The number of ions in the electrolyte can be quantified by the state of charge (SOC) of the battery. The higher the number of ions in the battery, the greater will be its SOC. So an increase in battery voltage leads to an increase in SOC and consequently a reduction in energy storage ability.
During a single charge process, as the battery gains energy, the voltage rises. This rate of increase in the voltage decreases as the battery charges up.
It was then inferred from this work that the very long time required to charge batteries at lower rates is not only due to the smallness of the magnitude of the current per say but due to the fact that at such low currents, the charging process is ineffective.
These determining factors include temperature, State of Charge (SOC), rest time, power rate, depth of discharge, and heat , , . Each of these factors contributes to the overall performance and its degradation process, whether the battery is operational or static.
These plots were utilized to decipher the voltages at the end of charge, beginning of discharge and the end of discharge for each constant current magnitude chosen. During the charging process, the ability to store energy in the battery drops as the battery voltage increases.
