This setup uses two batteries in parallel in series with two batteries in parallel. That way the batteries all have the same capacity while still have the same doubled voltage and increase mah. the voltage output would 3 volts (if using 1.5 batteries). Using this setup ensures that the batteries run a full cycle.
If we want to have some terminal voltage other than these standard ones, then series or parallel combination of the batteries should be done. One more reason for connecting the batteries in series or parallel is to increase the terminal voltage and current sourcing capacity respectively. Connection diagram : Figure 1.
Both of these designs have strengths and weaknesses. Hence both have places where they are optimal. Parallel and then series will be the lowest cost, but least flexible. Series and then parallel gives flexibility and redundancy and hence is often found in large battery packs.
Batteries A and B are in parallel. Batteries C and D are in parallel. The parallel combination A and B is in series with the parallel combination C and D. Again, the total battery pack voltage is 24 volts and that the total battery pack capacity is 40 amp-hours.
In this type of arrangement, we refer to each pair of series connected batteries as a "string". Batteries A and C are in series. Batteries B and D are in series. The string A and C is in parallel with the string B and D. Notice that the total battery pack voltage is 24 volts and that the total battery pack capacity is 40 amp-hours.
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. The ampere-hour capacity of the pack is determined by the capacity of a cell and the number of cells in parallel. This is the approach used in most passenger car electric vehicles and smaller battery pack designs.

A 0.5C or (C/2) charge loads a battery that is rated at, say, 1000 Ah at 500 A so it takes two hours to charge the battery at the rating capacity of 1000 Ah; A 2C charge loads a battery that is rated at, say, 1000 Ah at 2000 A, so it takes theoretically 30 minutes to charge the battery at the rating capacity of 1000 Ah;

Connecting batteries in series increases the voltage of a battery pack, but the AH rating (also known as Amp Hours) remains the same. For example, these two 12-volt batteries are wired in series and now produce 24 volts, but they still have a total capacity of 35 AH. To connect batteries in a series, use a jumper wire to connect the first battery''s negative terminal …
Notice that in some nodes (like between R 1 and R 2) the current is the same going in as at is coming out.At other nodes (specifically the three-way junction between R 2, R 3, and R 4) the main (blue) current splits into two different ones. That''s the key difference between series and parallel!. Series Circuits Defined. Two components are in series if they share a common node …
