Luyuan battery case

[Zwy]

Th 24V case like the 48V has 9 screws for the BMS-Pressure plate. It is pretty even pressure when done right. no need for more screws or attachment points.

Obviously you must not have a decent background in fabrication, even though you claim you do.

When you have all 9 screws installed that plate won't go anywhere. The Mounting Points are as generic as can be. Mine were fine for use with the JK INverter edition and those same points apply to Pace/Seplos & TDT BMS' of the same class. If using a different BMS then that has t be sorted. I can''t imagine you finding a casing that will accept "all formats" of BMS.

I used JK and she made the box according to that model of JK which is also one she offers in prebuilt.

So either the box builder f'ed up like the breaker hole or it is more of a "universal" fit.

The cases are designed to take a variety of cells (see sizes) so compensating for the space difference is up to use... I used urethane foam mesh on the side & at the front to compensate without issues.

Calling it a compression plate is a misnomer because the way it arrived there isn't any compression.

BTW: They are working on getting a few other Case Models/Types up for sale soon. They are looking at different formats and how they are setup / assembled (cell orientations & other issues). EVEN GSL has started abandoning packs with cells on their sides after all the problems & issues.

Anyways, I provided more info to help folks make their choices. The rest is up to whoever to make their choices.

I'm letting members be aware this isn't just a simple bolt together process. Unless they are willing to accept those tradeoffs. I'm not willing so will invest time and talent to correct what I see as deficiencies.

I own one of these and have 4 more on the way. The original case is the basic version which I used in my portable build. The next 4 are the updated version. My current JK BMS is the original design and the plate has 4 holes for mounting the BMS and the additional 9 holds for the screws to secure the plate. I elected not to torque these screws in since the cells were secure in their positions. In my case I drilled and attached a piece of polycarbonate sheet to the plate and used that to mount the BMS. In my case I had access to high end velcro from McMaster Carr and mounted to the plate using this. I could have also screwed the BMS on but decided not to.

I decided to go with the updated Inverter BMS and the box to match for the next delivery which should arrive next Thursday according to tracking.

Building it was fairly straightforward and Amy was quick to answer any questions.

Your quite correct that these (like any other) DIY kit will require a bit of fiddling but really not much. Time & Patience are most important. I built packs with New Cells and Cells I had in my own home made cases, some were plain LF280, some N, some K and their little variances. Some needed foam to be "snugged in" other did not. All needed a little on the sides, as determined by the X-Busbar and how that spaced out.

In fact, my 1st 6 cases were the 1st ones they shipped out, everything was fine. They had to send longer BMS Wires (I used diff terminals) and a screw kit that got misplaced in packing, Ohh and some different X-Busbars because of the different cells I was using in the packs.

"Compression Plate" or BMS Mounting Plate - same thing, It keeps the cells in place snugly as it should - just don't squish the darn cells.

Tracking just went live on 24 boxes of my order, should be here middle of next week. Waiting for the last six boxes to go live.

Tracking just went live

Exciting times! Mine went active last night as well.

Are there any detailed schematics out there of the 8s (280/304) version of the box? I'm looking for some specific measurements.
-Metal thickness
-width, height, depth of "bms compartment"
-Length of bms top hold down bar

I have one un assembled in my garage I can get some measurements from, metal thickness where? And BMS Top hold down bar, do you mean wire channel on top of cells?

Yes the wire channel with the battery vent holes. Length. Metal thickness you'd need caliper, I didn't find any gauge measurements on Luyuan anywhere. Also the interior space between "compression/bms" plate and front cover that screen attaches to. Those 3 measurements will give me an overall idea of volumetric capacities and I can extrapolate other measurements from.

Don’t know if these will help.

 

[BuffaloTrace]

This helps me a lot. And most likely many others. Thanks!
I like that most sites give overall dimensions of total size, but knowing about internal dimensions of parts and what not helps a lot if using non-standard equipment or sizing for shelves or planning for customization.

 

[ArthurEld]

Metal thickness is .063

My last two orders have been averaging about 30 days from order placed to my door. Considering it has to be transported and loaded unloaded on a ship and shipped across the country that is actually quite quick.

I also like the photos showing the order. Top notch service! It is also nice knowing that the products are extremely well packaged and arrive in the same excellent condition they were shipped in. I also appreciate the service Amy provides before, during and after the order is received.

I placed my order 5/12 (one 8s case, BMS and 12 280 cells), shipped to east coast started 6/5, I figure they’ll be at my door by end of the month.

Amy is already working on casings for cells that are coming... Seems folks forgot that 450-500+ AH cells will be released Q3, which of course will further help lower costs of "current" products. A Catch of course, they are going to be 12kg +/- each... 16x12kg = 192kg/423Lbs.

I asked about when they would be ready before I placed my last order and considered waiting, but with the tariffs I decided to go ahead and do another order when the large format cells arrive. Another reason I am doing a 24 volt system, I can stay around 250lbs with a case so still able to move.

 

[SparkyJJO]

Gonna need a forklift to move these things before long...

I am aware of the Winston/Sinopoly style cells (Yttrium doped). I've seen the 560ah cell specs from Eve. Are there others you're aware of?

 

[S Davis]

I am talking to Amy about a battery cabinet for these larger cells like I am doing for the current battery cases.

Tariffs on ESS cells is not a worry till later next year. I posted the info from the Whitehouse on that earlier.

EVE, CATL, Lishen and a few others. BYD cells are also coming to retail. The BYD formats are not the same so that's a tricky bit for now.

Several case designs are floating about ATM. Looking at a 16S with 8 Cells (upright) per level, 2 levels for 16S. Side Mounted cells NOPE ! Sorry everyone who bought the cases with cells mounted & pressed sideways, expect leaks on average of 2.5 years of use. NOT AN OPENING for arguments so don't.. there re too many photo's & lots experience out there that prove it along with several bankrupted companies. Stackable & Latchable systems and more...

LMFP is also coming to retail starting sometime in Q4 but that's more sketchy. Depends on how some things shake out.

IRONY is, because I am bound by several NDA's I could say a LOT more but can't and won't... It damned shame my daughters did not want the battery business.

Being that they will arrive so soon, are there any spec sheets available for these other brand large cell formats like Eve has released?
I have seen reports of the LFMP, and I understand these will be mainly released for EV applications as they have a slightly higher energy density and safety margin using the MP cathode.

Battery Business you say? I'm On My Way!....From California. Cya soon. Are you a West coast Canuck?

I am personally near Algonquin Park Ontario.
I do not and have never promo'd by ventures on here (no need). In fact I have gotten into deep shyte just for helping some folks and the manuals/guides really PO'd some characters who thought combatitive insults were appropro. I have "some" of my material here as it is generally relevant, even when people don;t want to know - IE the REALITY of the Volage Curves (Allowable & Working) which no one wants to know. Well that is, until they trip over it several times, when they grudgingly accept it. It took Andy's @ Andy's garage several of us telling him, him banning us only to realize 2 YEARS LATER that he should'vce listened and now "his realization & his recommendation".... blah... He even banned upnorthand personal for a while from leaving msgs. Such a treasure, even erased his early vids where he tells everyone he knows nothing and we will share in HIS learning exp. See dawg run off and not look back.

I’m getting my import registration done, don’t know if I will do cells. Might see if there is enough interest in battery cabinets to fit Amy’s cases to start. I will know better arter I get my personal samples produced.

Import for personal is one thing, but quantities / commercial that can become a sticky wicket in a hurry. Regardless of country, Cross the T's & Dot the I's or shit may fall upon you. There's no such thing as a good revenuer ! hehehe

The thing is, I used to use companies in Montreal, Toronto to make similar types of casings for another purpose. The mockup cost a bit to get right but the cost per unit after that quite good and with volume of course got better. At that time there was more manual effort & a bit more complicated. in 2024 with laser cutting, programmable stamping & folding, even spot welding, there's lot less manual work, faster, more precise & cheaper to produce overall. I have no idea what costs are "today" with those companies or similar ones. BUT get the right thing from China dn discounts can happen quick - S&H is the pita + 'fees' as applicable.

Got the ship name, current arrival at LAX is June 24th, chances of having the cells/case in hand before the July 4 is dwindling, not upset at all, I have no urgent need for them other than another side project to keep busy with

Not sure if they still have cargo ship backlog there or straight in and smooth offload?
