> A professional manufacturer would not put any cell in series but instead would have a charger/discharger with voltage per cell

My Bosch e-bike has 4 cells in parallel and put 10 of those in series. This so called 10S4P is a very typical setup for e-bikes. Each individual cell does definitely not have their own current/temp sensor. The BMS will check voltage for each of the 4 cell blocks.
