I’m listing here things that might have been a good idea to add/remove from the modules or things that I might want to change on future designs.
With only the 4 aluminum standoffs in the corners, the cell holder pieces were bowing a little in the middle when the bolts were tightened. A 5th aluminum standoff in the middle or better control of the tolerances could alleviated this, but the best workaround we found was to epoxy the middle cells in place and use them to secure the 2 sides of the module together. See the assembly guide for details.
The passthrough connections of the fuse board seem to take a lot of extra wires and crimps, which takes a lot of extra time. We maybe should have pushed for a wireless BMS for this version to save assembly time (only 1 connector required). Just wanted to put this down as something I noticed that we could save assembly time on.
