Eugene's correct - snake or "series" is the way to produce the voltage
needed.
Think of it like plumbing.
(-) is the faucet.
(+) is the drain.
Current is the flow of the water.
Voltage is the water pressure.
The batteries are the storage tanks.
The water flows from the faucet, into the storage tank, then out to the
drain.
When the tanks are together in a straight line the water flows faster
out into the drain. (Yes, I know it's not a perfect analogy but I'm
trying for concepts here.) Thus the speed at which the water flows
increases when more tanks are added in-line - the water pressure
(voltage) increases with each tank.
When the tanks are together joined in parallel the water still flows
from the faucet to the drain but *it takes longer to do so*. Thus the
pressure (voltage) stays the same but the time it takes to empty the
tanks increases with each tank because there is more water to flow into
the drain.
Hope this gives a slightly clearer idea of what's going on.
