S and P stands for Series and Parallel on an electric bicycle battery pack.
  • S is the number of batteries connected in series or (+) to (-).
  • P is the number of batteries connected in parallel or (+) to (+)and (-) to (-)
eg. A 3S5P Battery Pack has 3 batteries in Series (S) and 5 batteries in Parallel (P)

eg. A 13S14P Battery Pack has13 batteries in Series (S) and 14 batteries in Parallel (P)

Battery cells connected in series increases the voltage of the pack, whereas battery cells connected in series increases the amperage of the pack.
