If you "split" a cell, it will produce the same voltage, with half the current of the original cell available from each new cell (assuming you split it in half)

Each cell will always provide the same nominal voltage, and the current is relative to the size of the cell.
if it does retain the voltage if we put the cells into a series does the voltage add together?
(from a cell with .5 v and 6 amps split into two .5 v and 3amps, then put them together does it become 1 volt with 3 amps?????? is that what your saying????

It is not a good idea to put cells in parallel without some other devices to prevent the parallel cells from self discharging. (the cell with the higheer voltage will pass current to the cell with the lower voltage even if the cells are only a few millivolts different they will pass current) You cannot put two different cell voltages in parallel, the higher voltage will feed current into the lower voltage until all cells are at the same voltage.
yeah were going to have like a power tracker or something to help us not discharge so if we do what happens to the voltage??
