Looking for cases and annoyed how expensive they are. Almost same price as buying all the budget cells that will go in.
Don't see why they cost 400 bucks and up for an empty box. Is it the size and weight that makes it expensive?
Maybe not mass produced item. You can get a fancy computer case for 100 bucks.
I think once I build I'll just diy case with material I find locally.

Maybe need to buy several directly from china to get a price break. But shipping and customs ding you.

docanpower has the Apexium 280Ah diy case with jk inverter BMS for $640+5% out of Houston.

I got my 24v cases for $160.00 each earlier this year including breakers and internal wiring, from Amy@luyuan even had some custom cases made to house two 12volt 304ah each with own BMS and screen.

I used a Buyer's underbody box. There's a lot of good options in the tool box and automotive box market, but the modifications do take some time and effort.

Blue sea has nice through panel lugs to make the terminals.

Were those a custom order or a "Add 2 to cart" option? What BMS came with those? Breaker with those?

I'm hoping I can avoid building a box because all the 8s box kits I've seen are way more than I want to spend.

You need to chat with Amy to get a accurate quote, BMS and screen were extra and she has multiple options. I ended up ordering 8-24 volt cases and 4 of the 12 volt custom cases along with EVE LF304 cells.

I just paid $240 w shipping for a battery case I Like for 16 x 280 ah cells: I purchased the XR07 Case from Dongguan Xinrong on Alibaba. It then took about 3 weeks to arrive to my California address from a Canadian warehouse. I like the more economical price I have seen, plus the plastic sheeting to insulate battery cells from metal, plus it has stick on foam to place between each cells. Here is picture of it partially assembled. I have a new set of 16 (plus two extras) LF280k cells from Docan I am going to hook up to the older reputable smaller back box JK BMS (that has better reviews than JK's newer longer inverter ? type of BMS), and make that work. If you order one of these case, make sure to match up for Ah size, and for the JK LCD size you will be using. I ordered the XR07 48V 280AH case for 280 ah and 302 ah cells, & larger JK LCD screen :+)

Learning Curve. I wished I had cycled the cells w BMS down to 20% then Recharged to full to see how close the cell voltages matched through up and down soc cycle, before compressing them in the case, and wiring them up. Turns out that one of the Grade A EVE LF280k v3 cells I purchased from Docan in faulty, and peaks enough to trigger 3.65 v max before the other cells are fully charged. The other 15 cells were within 0.004 v diff, and likely could have been charg d to full with 2A Balance turned off. I am glad I ordered a couple of extra cells for down the road maintenance. Hope Docan can replace the faulty cell I received, and will find out about that soon.

Update: Just dialed in my 48v 300 ah battery case with cells and the smaller better reputation JK BMS (unless new firmware is getting good reviews). I must say I Like my first LiFePO4 case. No directions, but was almost obvious how to assemble. I likes how each cells get sticky side foam padding, and top plate against battery can be removed, then replace and screwed down to apply some battery compression. All the screws fit where they were designed to, and none stripped out. Even found some screws in kit that fit into tiny mounting holes of my JK BMS that I have never found before. Pictures tell rest of story. Previous post shows brand. Case cost about $240 w shipping. paid about $1200 for the LiFePO4 cells from Docan. JK BMS with larger LCD screen cost me about $140 +? from Aliexpress. I covered display holes and print for longer inverter type JK BMS with sticky tape, then clear tape (might epoxy metal piece later) . I Like my new battery case.

As an update to this thread, I eventually went with the Midnite Powerflo16 because I wanted to install it outdoors and the construction seemed to be really good. See this post for images: https://diysolarforum.com/threads/midnite-solar-batteries.86462/post-1292403

Thanks for the post. I was heading down the road to build more oak boxes but this case looks like I can get some compression - even if I need some small mods to beef up the steel. Ironically I bought the exact same BMS so i''l just follow behind you I got 4 so I can redo my 2 origionals and add 2 more packs... And it's priced at the point where making it is just not worth the time. Same place and price as yours. Though I would like to find out if the connections PCB module (rs/can rj45's ) can be putchased and used with the BMS's we have.. Even willing to redo the connector ends if necessary ... 11.60 ea for 4 I'll give it a try I only want the CAN/485 ports since I do want to connect them together and to my SolArk CAN and it will fill up the holes ! This should be a nice change from my home boxes - though I think the do a better cooling/compression job I'll take the cleaner more compact cases since the room is small and I'll have 4 now. I will not miss the heyo clone daly BMS's

Looks like a good setup, I'm close to pulling the trigger on 32 (plus a couple as back up) 280ah cells from Docan and I'm shopping for a diy box. Are you connecting them to a set of EG4 3kw inverters? Thats what I have as well, I'm hoping one of these DIY boxes will be able to communicate with my EG4 inverters in closed loop. Have you been successful doing that with your setup?
