The greenish-yellow plastic slices are for water cooling. Inside each are 3 pouch cells in parallel. You want to get these compressed again carefully. I fabricated new custom length bolts from a length of threaded rod. In order to fasten to the steel plates at either end of each module, the rod bolts have to be M6x1.0. Grainger Item# 25DL85 is $1.67 for a 3 foot length. I needed 12 of these (36 ft).

At left is the same module assembled (but before I cut the threaded rod to finish length). Below are three 48v modules bolted together.
