About a week ago after I found the construction problem in the 12V batteries, I cutout the end of each battery to access the Cell terminals and attempt to band-aid the problems to see if the cells were damaged.

You can see some big washers and even stacked washers to get the tension onto the Link bars which were unable to be clamped correctly due to insufficient screw hole depth, they were drilled incorrectly and there is no way I'm going to attempt to drill the posts. There is enough thread to get good tension if you stop the screw from bottoming out.

This is the second 4 x 12v bank I'm about pull down for another 16 EVE cells.

The Anderson connectors are where I plug in the Active Equalizer and also where individual 12v batteries could be adjusted to keep the bank in balance if needed.

The Meters quickly added to keep an eye in each bank as I load tested and High current charged them during the tests, also monitored each cell during the process looking for any obviously bad cells.
