3.4. Parallel connection

  • When connecting cells in parallel, the currents of individual cells are added.
  • The voltage of the parallel connection is equal to the voltage of one cell.
  • The performance of a parallel connection is the sum of the performance of individual cells.
  • The capacity (Wh) of a parallel connection is the sum of the capacities of the cells.



Note
If we required a rated current of 200 A, it would be necessary to connect 77 cells (or serial branches) in parallel.

Total power: P = 77 * 3.7 * 2.6 = 740 W
