The single-cell configuration is the simplest battery pack; the cell does not need matching and the protection circuit on a small Li-ion cell can be kept simple. Typical examples are mobile phones and tablets with one 3.60V Li-ion cell. Other uses of a single cell are wall clocks, which. .
Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2shows a battery pack with four 3.6V Li-ion cells in series,. .
There is a common practice to tap into the series string of a lead acid array to obtain a lower voltage. Heavy duty equipment running on a 24V battery bank may need a 12V supply for an auxiliary operation and this voltage is. .
The series/parallel configuration shown in Figure 6 enables design flexibility and achieves the desired voltage and current ratings with a. .
If higher currents are needed and larger cells are not available or do not fit the design constraint, one or more cells can be connected in parallel. Most battery chemistries allow. [pdf]
