This is because lithium-ion cells have a depleted voltage of about 2.6 volts, a nominal voltage of 3.7 volts, and a fully charged voltage of 4.2 volts. So, that means 7 lithium-ion cells in series will have a nominal voltage of 25.9 volts, a fully charged voltage of 29.4 volts, and a dead voltage of around 20 volts.

How to calculate the lithium content in a battery
The amount of lithium (or lithium equivalent) content in a battery or battery pack can be worked out as 0.3 x amp hour capacity. So a 2Ah battery has 0.6 grams of lithium (2 x 0.3) and a typical laptop battery pack with eight 2Ah cells has 4.8 grams (8 units x (0.3 x 2Ah))

How many cells in a 48V lithium battery?
The number of cells directly affects the voltage output and overall performance of the battery. To determine how many cells are present in a 48V lithium battery, we need to consider two key factors: nominal voltage per cell and total voltage required. Each individual lithium cell typically has a nominal voltage of around 3.6 volts.
