Luyuan was quite a bit cheaper.

No idea. I didnt. Just a simple chat with Amy got me what I needed.
I mentioned Steve and she said, "Steve who?" LOL!
Exactly. More Ah in a smaller footprint for less money, that's why I DIY. Now, my addiction with blue components can't be explained away as being less expensive so I'm working on that argument.

Psssst: Luyuan also sells Fully Assembled battery Packs IF you don;t want to or can't DIY.
You save money on DIY batteries to feed your blue addiction. Duh.

I’m developing that same addiction. I can’t wait until my boxes show up. I was watching a teardown video of the SOK server rack batteries on current connected’s youtube channel. They aren’t so dissimilar from these DIY packs, so I feel pretty good about it. The only notable difference was in the SOK battery, there were additional metal racks for each set of 8 cells. I don’t really think that would be feasible with the large 280ah cells anyway.

Blue? What is blue?

I thought you saved more and that justified more batteries? But I can get inverter credits?
Victron Energy components are all the same color: blue.
Well I would get more batteries, but some people are afflicted with blue addiction.
It's a delicate balance.
For those of you with a 16s box and 280Ah EVE cells, how much room is there on the long side of the batteries (short side of the cells)? I'm trying to figure out if I can fit warming pads against the batteries.

I think for many on this site, the addictions are an "and" rather than an "or" issue!
Seeing Luyaun doesn’t actually make the case (they are primarily a cell reseller), I think waiting for these cases to be “prime time where no tweaking is needed” is going to be a while.
What I liked was a case that was customized to my needs with a contact that has had good track record (plus known good cells). With that I knew I may have to spend some time tinkering to polish it off to my liking.
If I needed 5 cases the tinkering would probably get old but so far for my first unit I’m happy.

I have another box in the house waiting on final assembly so I put the cells in and checked for you. 7/32" clearance on the side with cells pushed towards center, a 1/4" bolt won't quite go in and this was with separator sheet out on the outside.It's a delicate balance.

You do have the option to use the center divider bracket which is about 3/4" wide.
Thank you for the pictures and measurements. I didn't realize the divider was "hollow". I think I can work with that.
The plan had been to use RV tank heaters that have been adapted (by the mfg) to work on batteries. The space on the side would be enough for the warmer.
However, the warmers seem to require direct adhesion (my current warmers work that way). I would really like to get away from direct adhesion as it makes it very difficult to replace on cell in the series. Adhering it to a sheet of aluminum - instead of directly to the battery - is an alternative, but that increases how thick it is and may keep it from fitting. I'm going poke around in the battery warmer threads to see what I can come up with. Low amperage for slow heating and something that can cover the entire side of the battery.
The RV tank heaters I used in the last build were quite expensive but they were custom made to fit the entire long side of the 12v battery. That was great coverage and worked incredibly well. My batteries were warm and cozy.
Your picture also shows that there is plenty of room between the tops of the cells and the top of the battery box. Enough room to put a Class T fuse in there if I decide to go that way.
