"Tabless cell" the new new In lithium ion Tech

I just built an 18s5p with the AM04 cells and I’m very very happy with the results.

Also have an 18s1p that I’m doing high amperage draw tests with and it’s holding up very well also.

Got another buddy that i built a 20s2p split pack for with them, waiting for it to be installed.

Also have 2 more 18s2p packs on the bench being built as we speak.

These outperform p45b without question

x240 40PL cells ready to be made into packs by spiderbatterysystems.

Keeping an eye on bak45ds still.

If y’all are interested I got a 40PL ct scanned as well as a 30T for tab comparison. I can navigate to any depth and any angle on each of the cells and take a hd picture from it if anyone is interested in anything in particular. Here is a video of the 40PL to give you an idea for what it’s like.

This is really interesting.

What would be neat, is to have a 0.2mm nickel strip welded to the terminals, and see the gaps between welded area and adjacent nickel, to see how much of a gap opens up, and at what distance from the weld(s).

I also wonder if the welds would be visible on the inside of the can, perhaps cloudier electrolyte directly adjacent and slightly thinner metal?

Does this mean I can order a tabless pack from @SBS now???
