I might add that when I clamped mine that I measured the space between the boards at each rod and equalized them to within a 1/16th of an inch [or less].I asked a vendor I’m in contact with about this issue of whether or not to clamp cells today. They answered :
“If discharging at 1C or more then yes, it would be better to compress them. Because high current charge/discharge will cause the cell inflating. Otherwise, it is ok to make them without compression. Because if amps is large, much heat will generated, and the cells will inflate a bit.”
And they supplied the attached photo to illustrate a typical clamping arrangement. Note, this wasn’t specifically in connection with Eve 280Ah cells, just general info.

This way there was absolutely no unevenness in the compression. Looks like they did this also in the picture above.
Sounds like good advice.
