Hi. I bought batterypack from last group buy. It was wery low quality and i took it apart. 2 series were drifting all the time and now i did measure cell voltages. I wonder if this is caused by bad welding or crappy cells? 8 of the 4 sets (8s4p) were all 3.82V per cell and these 2 were drifting like crazy.
When i connect them in parrallel it should balance itself all 4 cells?
