What is a 5p battery pack?

Commonly cells in parallel are abbreviated in terms of ‘P’, so this pack will be known as a “5P pack”.When 5 cells are connected in parallel, ultimately you made a single cell with higher capacity ( i.e 4.2V, 17000 mAh ) Voltage (Volt) : The desired nominal voltage of the battery pack is 11.1V. The nominal voltage of each cell = 3.7 V

How many volts does a chemistry pack have?

Those chemistries have a nominal (average) voltage of 3.7Vand in order to get the longest possible life from the pack, use 3.3V per series-cell as the Low-Voltage-Cutoff (LVC), and 4.1V as the fully-charged target. Seven cells in series in a 7S/4P pack, which is a nominal 24V. This is 28.7V when fully charged to 4.1V per cell.
