There are three cells in each of eight batteries.
Y'all are talking like each cell in each battery is not susceptible to this same imbalance failure, no? Each of the three cells is a unit made of differing quantities of "paste" applied to thin poly film.
Mechanical differences among these cells would seem to be the primary cause of failure. As small as one perforation or even ion by ion, the "Battery" is an
accumulation of billions of cells, the electrode must collect and evenly distribute this energy to the connectors. Imbalance is the enemy, everywhere. Not just among eight gross boxes.
The failure is primary to a location on one of the three cells. Imbalance within the cell would seem to be the fault.
Moreover, each cell has millions of perforations on its separators, each one operating at a miniscule potential, and separate from all other perforations.
Balancing the batteries amongst themselves would NOT seem to be the answer.
This is a spontaneous failure. Spontaneous not meaning "Instantly".
Spontaneous as in "self creating". The charging
exacerbates the failure it is not the genesis of the problem....
Conduction and resistance is causing the problem. Charging is just one of the roles of the system.
This battery is not happy with its work...
