Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
It is essentially a measure of how long the battery can last before it needs to be recharged. When choosing lithium cells for a 12V battery, you need to consider both voltage and amp hours. To achieve 12 volts, you can either use multiple cells connected in series or choose lithium cells with higher nominal voltages (such as 3.7V).
If each cell is 10 amp hours and 3.3 volts, the battery pack above would be 10 amp hours and 26.4 volts (3.3 volts x 8 cells). For this setup, a BMS capable of monitoring 8 cells in series is necessary. Lithium cells can almost always be paralleled directly together to essentially create a larger cell.
Paralleling strings together greatly increases the complexity of managing the battery pack and should be avoided unless there is a specific reason to use this configuration. In this setup, each string must essentially be treated as its own battery pack for a variety of reasons. In a below example, 2 strings of 8 cells each are placed in parallel.
Easy Connection：Smart compatible strings from 4S-8S 12V-24V.It can support Lifepo4/Li-ion/LTO battery pack.Also supports parallel battery pack configuration. Smart 1A Active balance BMS: Which helps equalize the state of charge/discharge across battery cells for longer battery life.
To determine the number of cells required for a 12V battery, you need to know the nominal voltage per cell. Most lithium cells have a nominal voltage of around 3.7 volts. So if you divide 12 by 3.7, you get approximately 3.24. Since you cannot have fractional cells in practice, rounding up would be necessary here.
