Charging 4 cells in series with TP4056
This is NOT going to work!
The - input and - output of the TP4056 module are connected and that will short your battery. I have indicated one of the shorts in purple:

To be able to charge 4 cells in series with 4 TP4056 modules you would need 4 separate, isolated power supplies.
But I would not recommend that. The proper way to charge 4 cells in series is by using a charger that is designed for that task. It should include balancing so that all cells will be charged to the same voltage despite differences in capacity between the cells.
