The Single Terminals are plated copper, M8 Bolt, dimensions are 35mm X 35mm, cover dimensions are 108mm X 90mm.
I don't really care whether I have single or double terminals but since you are verifying that the single are copper, I am ordering singles from now on. I suspect the double terminals are brass.The Single Terminals are plated copper, M8 Bolt, dimensions are 35mm X 35mm, cover dimensions are 108mm X 90mm.
I think your plan to fill in the space will work. I added 2 small extra spacers to mine. And you will be fine without the display if you stick with the JBD.I think to make the box work with my 230Ah cells would mostly just be a case of filling the extra space with something and using the right bus bars. Shouldn't be too difficult to make happen, even if I have to do it myself.
Still debating whether to change to a JK BMS or just stick with my JBD contactor BMSes. They're way overkill being rated at 300A, but I have them already. Probably fine to stick with, be cheaper, but...
Not insulated on top. If you threw one off a building it would short.I don't see why them touch each other would hurt anything. The cells are insulated from the box.
I'd like to see you carry it to the roof of a building to throw it!Not insulated on top. If you threw one off a building it would short.
Mine came with a small ground screw on the front panel, down low right side. If stacking I would use some type of rubber between four corners(horse stall mat should work) to keep them from sliding around. I just had her add heat function to the BMS for my mobile packs.I caught Amy in time to use the single terminals on my front panel.
Can someone please tell me if these battery boxes should each be grounded?
Also, I am stacking mine on top of each other. Do I need to put something between them to keep the boxes from touching each other?
They are from Amy. I said I wanted the new batteries with the pressed copper flexible bus bar connectors like some one on the DIY solar forum recently ordered and she knew exactly what I was talking about. She even sent me this image in the chat to make sure. As for the of the terminal holes for the single vs the double, you should ask her. I do know they had to custom cut the holes for my cases.Nice. Are those from Amy's or separate purchase?
Now I wonder if the dimension of single terminal more likely same as dual terminal lol
Ground the case only. I'd daisy chain from the ground hole on the front cover to the next box. Should not matter if they touch.I caught Amy in time to use the single terminals on my front panel.

I assume I should attach the ground wire to the ground bar in my inverter.Ground the case only. I'd daisy chain from the ground hole on the front cover to the next box. Should not matter if they touch.
To system grounding. Doesn't need to be inverter, it can be a grounding bus bar or direct to grounding electrode.I assume I should attach the ground wire to the ground bar in my inverter.
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.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.

My order is ready but it is a holiday in China so the shipping company is closed until Monday.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.
I have about half my stuff so plenty to work on.My order is ready but it is a holiday in China so the shipping company is closed until Monday.
Jealous!I have about half my stuff so plenty to work on.
The boxes come with fr4 sheetsAre you using separater material between the sells?
