Neat system to be honest.

I suppose you don't have those components?
No, unfortunately, I don't, only the cells. I made my own bus bars. Just need to sort the box, and some enclosure to protect the BMS from damp, and I'll be away.

If you watch teardowns of ready built batteries on you tube that are using large prismatic cells, you will see that compression is not used, at the best the cells will be taped together.
I suggest installing with insulating material between cells and the metal and aiming for a 'snug' fit with the cells at around 50% SOC. High density closed cell foam or neoprene could be used.

Good discussion here,


I assemble similar to the picture below with high density foam sheet on each end plate ( metal or thick ply). The cells are held under slight restraining force whilst the side plates/ply are fixed in position.

To overcome any issues with buss bars I use flexile braid.

I see you are in the UK,

high density foam sheet available on ebay , various thickness including adhesive backed .
Must be closed cell to avoid moisture issues.
high density foam
To isolate between cells use high temp baking sheet,

do you have a link to those buss bars?

I have used the Winston factory battery straps before. They do not compress the cells, just hold them in place.

Now i use one or two rows of PV mounting rail to surround the plastic cells.
