What is the effect of increasing the number of cells in parallel?

Increasing the number of cells in parallel directly leads to an increase in the current capacity available from the battery. When multiple cells are connected in parallel, each cell can contribute its own current output, effectively allowing the total current supplied to increase proportionally to the number of cells added.

For example, if each cell produces a current of 1 ampere and you connect two in parallel, the total current capacity becomes 2 amperes. This increase in current capacity is particularly beneficial in applications requiring more power draw without altering the voltage of the system.

The other options do not accurately reflect the effects of adding cells in parallel. Increasing the number of cells in parallel does not change the voltage output, which remains consistent with that of a single cell in the arrangement. Additionally, adding more cells typically results in an increase in weight, as more components are included. Finally, the charging voltage required does not increase with additional parallel cells; it remains consistent with the voltage of individual cells.
