White Paper - Notation for Series / parallel arrangement of battery cells
Interactive utility to explore and get notation for any arrangement
This interactive utility allows you to arrange cells in a battery, displays the standard notation for that arrangement, demontrsates how the specifications are affected by the arrangement, lists pros and cons, and shows graphically what that arrangement looks like.
In a battery with cells both in series and in parallel, connecting the cells first in series or first in parallel does matter: it affects performance (in case of weak cells) and cost (BMS complexity).
The order of 'S' and 'P' in the notation for the arrangement does matter: it indicates whether cells are first connected in series or in parallel. 3P4S means that 3 cells are connected directly in parallel first; while 4S3P means that 3 strings are connected in parallel last.
