Hi, a great explanation of batteries in series/parallel…thanks! A couple of assumptions and questions, based on your Figure 15 diagram above: – Assume batteries are, from left to right, 1, 2, 3 and 4 – All batteries are 100ah – Batteries 1 and 2 together, and 3 and 4 together are serially connected – Batteries 1 and 2 together, and 3 and 4 together constitute …
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.
Now this battery pack hack is modified to use series parallel. (you will notice I cut off one of the battery holders, turning the 4pack into a 3 pack) If you have a good understanding of parallel and series then you can probably figure out what both combined does. If not I shall explain!
A structural battery pack is designed to become a structural component of the EV. This approach can reduce the EV’s weight by removing duplicate structures between the pack and the vehicle structure, as the battery pack becomes part of the vehicle structure. This design can improve the EV’s overall performance and efficiency.
Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of a combination of series and parallel connections. Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve a nominal voltage 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh.
The coefficients for the different types of pack. This selection will be improved as we get more data. The SeriesParallel worksheet hopefully gives you a tool that allows you to understand how changing the configuration of a battery pack changes the voltage range, total energy and mass.
Such a configuration is called 4s2p, meaning four cells in series and two in parallel. Insulating foil between the cells prevents the conductive metallic skin from causing an electrical short. Most battery chemistries lend themselves to series and parallel connection.

When designing a battery pack it is useful to make a few series and parallel calculations. Hence one of the worksheets in our Battery Calculations Workbook is exactly that. Cells that are in parallel have the positive terminals all connected together and the negative terminals all connected together.

Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2 shows a battery pack with four 3.6V Li-ion cells in series, also known as 4S, to produce 14.4V nominal. In comparison, a six-cell lead acid string with 2V/cell will generate 12V, and four alkaline with 1.5V/cell will give 6V.
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. A million thanks to the ...
Before connecting batteries in series or parallel, we generally check the voltage of each battery to ensure their consistency.
