1- 1X BMS Master with arduino 
2- nX 24s Scalable Slaves using tp4056 and normal USB chargers (Total ) > I will build 4x 24s slave to have 96 batteries pack in series (400v DC)
2.1 - each slave will connect to each other and first connect to master
2.2 - On slave side 74hc595 will read voltage of each battery and control tp4056 R3 resistance to charge faster or slower and stop charge if necessary. For instance we can use R3 to charge until 3.9v or any other voltage
