Luyuan battery case

[JJJJ]

After reading a couple of other threads considering placing my MRBF fuse (I am 24v) at the positive terminal of the case and running my wire from there.

I assume I should attach the ground wire to the ground bar in my inverter.

To system grounding. Doesn't need to be inverter, it can be a grounding bus bar or direct to grounding electrode.

Whoo Hoo!!!
Amy is sending my order out! I am so excited.
@solitarysecluded my guess is that Amy can customize quite a bit. If you have a specific width you need, you should ask her.
I am attaching the image Amy sent me of my cases before she boxed them up. Here is the data sheet she sent me of my Eve 304A cells. I added some measures of center because I was using it to show someone the basics of Google Sheets.

Mine are taking longer as I customized four of the boxes to twin 304 12volt batteries with cutouts for two BMS screens, breakers, switches and mounting for two BMS.

My order is ready but it is a holiday in China so the shipping company is closed until Monday.

I have about half my stuff so plenty to work on.

Battery #2. Class T attached to inner compression panel.

I am happy with the footprint of these new batteries.
Stacking 5 cases will take less than 1/4 of the space compared cells on shelves.

Are you using separater material between the sells?

The boxes come with fr4 sheets

I used the yellow separators supplied with the boxes

I'm fabbing up a sheet metal plate to attach to the compression plate (if you can call it that). BMS and T class fuse attached to it. Plus some lugs to combine BMS leads.

I used butt connecters to extend the BMS cables and I double sided taped the BMS to the fiberglass plate included with the kit. I thought about making a sub plate like you but I decided to go the easy way. If I get around to going with the closed loop, I might have re work my setup.

I know, I have been planning on eight boxes in two AV racks but was looking at my work bench in the garage and started thinking I could fit two banks of six under it if I modify it with some steel. I wonder if 12 is the magic number

GRINS, starting to sound like someone needs a 12-Step Program, LOL.

Or maybe 24

Four more boxes and 32cells.

keep wanting me to open on the app, which I am not downloading.

This is the biggest downside of Ali* for me, feels like an inverse intelligence test. And Temu won’t even show me prices without installing their app, so #ThankYouForPlaying

 

[ArthurEld]

I tested my first two batteries charging and discharging 150 amps and nothing got excessively hot.
The dual terminals worked fine.

New dual 12volt 304ah box fronts.

So will this be two 12v 304Ah packs with separate BMSs in parallel in one box? With one set of external terminals?
