busbar for connecting sets

[crashintoty]

I'm building my 48V LiFePO4 battery with 16 cells with 2 rows of 8 cells. Where can I find a bus bar that connects the two sets of 8 cells (like the one pictured below)? And what is it technically called?

That would be a flexible multilayer cell link busbar.

Some kits just provide a nickel plated plate, seeing movement isn’t much between the rows, flexibility isn’t that big of a concern.

If you are willing to wait/take the chance, I've found prices on Aliexpress tend to be cheaper but quality seems on par with the Amazon/ebay stuff.


A lot of the manufacturers are laying cells on their side to build their batteries, so it must be ok, but does it make anyone else cringe, or is it just me?

Thanks for the replies, but the interconnect/multilayer cell link bus bars suggested (100 mm x 35 mm) are designed for sets with no gap between them. Due to compression, my sets have a threaded rod between them so I need a interconnect bus bar that's at least 120 mm x 35 mm. Any ideas?
