Here's why:

* Batteries in Series: Connecting batteries in series *increases the voltage* of the battery pack, not the current. The current capacity remains the same.

* Batteries in Parallel: Connecting batteries in parallel *increases the current capacity* of the battery pack, not the voltage. The voltage remains the same.

To achieve a current of 6 amps, you need to consider:

* Battery Capacity: The individual cells need to have a sufficient current rating to deliver 6 amps.

* Connection: You'd need to connect the cells in parallel to increase the current capacity.

Important Notes:

* Safety: Always consider the safety implications of connecting batteries. Using cells with incorrect current ratings or connecting them improperly can lead to overheating, fire, or other hazards.

* Voltage: The voltage of the battery pack will be determined by the voltage of the individual cells. Connecting six 1.5V cells in parallel will still provide 1.5V.

For a more accurate answer, you need to provide the following information:

* Voltage of the individual cells

* Desired voltage of the battery pack
