What will happen if, when transporting this box, you put it on the narrow side? I don't think that plate on top can hold the weight of 8 cells (40kg+). Some cells will go to meet other cells, this will be a "fun" and unforgettable meeting. Especially since there is no insulator between them that could prevent this meeting.

you completely ignore requirement from manufacturer to apply pressure in order to achieve 6500 cycles. Without it - only 2500 cycles.

If these are virgin cells that have never been given a top charge doing so with them laying on their side will most likely cause any trapped gas bubbles from manufacturing to collect in the cell laminations and reduce the cells effective current.. little to no pressure during the seasoning/break in time also reduces the chance of pushing the bubbles if any out.. After the 10 to 50 cycle break in where you take the cells to 3.6v or 3.65v a couple times slowly then gradually reduce top charge to 3.45v or 3.5v per cell for the life of the battery you can reduce or remove compression with little to no loss of lifespan.. Keeping the charge/discharge levels below .5c or best below .3c and cell voltage between 2.9v and 3.5v will extend the life of the cells to well over 15 years or 8,000 full cycles till you reach the 80% capacity range which gets into the time degradation of the cell materials.. Keeping them below 80 deg. F at all times is another life extending desire thus the .3c rate..

Agreed, you can blow the BMS the way it was done..
