Will the battery pack okay if the cells are not glued together?

This is another question for my diy project (https://endless-sphere.com/forums/viewtopic.php?f=14&t=97736)

Since the battery case is too tight, if the cells are not put inside the cell holder, there will be more space for the BMS and wires. I saw a lot of people would glue the cells together if they are not using a cell holder. But if later a group or a few cells need to be replaced, then it will be quite difficult. I have a currently using battery pack (made by someone else) which is with cells not glued together. Therefore, I would like to not gluing the cells together. Please give me your comments if it is okay not to glue the cells together for my project.

if not glued it's possible for cells to chafe through (due to vibration) the very thin PVC sleeves and short.

for added protection i like putting a layer of kapton tape between opposing parallel groups, then bonding w/ silicone sealant

I have the same case, and I was able to fit 13s5p (the full 65 cells) with the battery holders.
I also was able to fit bms and 2x2.5mm2 for both negative and positive leads.

It was a very tight fit, esecially at the connector in the bottom where it exits the case.

I later remowed the bms and the weak standard connector, and replaced it with andersson type connector and 6mm2 leads.

Here is a picture, I think it is when I removed the bms.

This is what it looks like now:

With hot glued connector and a computer connector for the balance leads. It sits where the on/off switch were in the case.
