You cannot combine different capacity batteries in series. There are a few points you need to consider when wiring in parallel. Let's explore these three points.
Lithium battery parallel connection is to connect the positive poles of multiple batteries together, and the negative poles together, so that the total capacity can be increased while keeping the voltage unchanged.
Battery parallel connection entails linking multiple batteries together by connecting their positive terminals and negative terminals, resulting in a collective increase in the overall capacity of the battery pack.
A battery parallel connection involves linking multiple batteries together by connecting their positive terminals and negative terminals. This arrangement increases the overall capacity of the battery pack, shares the load evenly among the batteries, and results in a higher current output.
This combined setup is necessary because relying solely on one method may not meet the power requirements. By combining series and parallel connections, battery packs can be customized to deliver the desired voltage and capacity. For simplicity, battery packs are labeled with abbreviations : “S” for series and “P” for parallel.
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.
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.
If you want to add more cells in parallel, connect the positive terminal of the third cell to the positive terminals of the others, and do the same with the negative terminals. This configuration increases the overall capacity of the battery pack without changing the voltage.
In a battery parallel connection, each battery shares the load evenly, leading to a higher current output.
