Now sure what you mean by that.
If you are talking about putting a fuse between the Case Terminal and the cable lug, I do not think that is possible. The MRBF's have no structural strength (just like other fuses) as they all require a base/holder of some sort, pending on fuse type.

No problem, Coffee #2 is always best to have underway before posting... (for me anyways) Sometimes #3 if it was a long night.
I have never seen what you describe, the fuses would get busted a lot that way. They also only go around a 5/16 bolt.

I haven't had time to do anything with my cases yet. I am hoping we can come up with a smooth way to put fuses in the case. I'm sure I can make something work outside if needed.
I'm 48V and will be using class T fuses for each battery.

LMAO ~ Well folks, bored ?
My fun begins ! some assembly required and lot'sa patience. lol
All of these get a 200A JK-Inverter edition. New 4.3" screen.
All get Single M8 Case Terminals.
This stack of 6 = 68" high. NO CELLS inside "yet" as this is just unpacking and prepping for assembly
<--- #1 waiting for cells to top charge...
#2 and below standing by waiting.
Sometimes I wish I had 6 arms & hands...

It takes about 3 hours to assemble & prep a case, installing BMS etc provided you have everything at hand and ready to go... tools, crimpers etc.
JK's Inverter model is a good fit. Wiring the new BMS for 8S is not as easy as previous model. I asked questions etc from JK and they went Dead Stick no response AGAIN... Someone did ask if I was going to write another manual for them... not doing any of that again, tried to help others before & got slammed for it and then plagiarized by many...

MRBF are just throu hole fuses.
It’s a bolt holding a lug to a bus bar clamping the fuse in the middle, I don’t see how it’s be any worse if you just say mounted it to a 5/16” terminal lug of the case.
Would someone be able to stack a 2nd lug on one of those M8 terminals you got or is it designed for only one and you are going to home run each case?
I will be running a line to the fuse holder at the bus bar. Quick and easy

By default they come with a Dual Terminal on the cases. I did not want that because my setup/layout and the end result that I want.
I mounted mine directly to a blueseas disconnect switch.

I have a pair of PB2A16S20P's with the large screens, in use now. (16Channel200MaxAmp2AmpBalance) They've been running great for 4 months or so.
The stud is isolated in the mrbf holders, otherwise the stud would bypass the fuse

Oh snap I didn’t think of that, good call.

Are those all going to be filled with the EVE 304A cells?
That would be 46,694 Watt-hours! Awesome.

24V system, 8x 280AH cells per case.
1680AH / 43kWh

That is still pretty nice!
I just ordered 4 of the 304A battery kits from Amy. Plus a 12v to switch my RV house battery over to lithium.
Now the hardest part is waiting! I feel like a 6 year old who knows their getting a new bike for their birthday.... but it's two months away. (Is it here yet? Now? How about now?)

My fifth and sixth 8s box is arriving Monday
My first order took about seven weeks but Chinese new year holiday was in the middle of the order, and the second at just under five weeks arriving Monday. Just getting next order together to complete the 57kwh bank.

Amy told me it could take 3 weeks to get the cases cut and everything ready to ship, so I imagine it will be 2 months before I am going to get my hands on them.

Cool idea S Davis. I would cover the fuse and everything connected to it. It's too easy to make a mistake with all of that metal exposed. Tape is way better than nothing.

Looks like a good solution but a couple of ?
How much space between the fuse mounting & BMS when installed ?
As I am assembling my cases the real estate in there is snug (JK Inverter BMS). You certainly want bit of room between components.
As Arthur point out, that Angle is screaming at me as well...
Trim to reduce size. TRIM all corners (round them) & edges and have NO SHARPS AT ALL ! You likely noticed that the case edges are all "soft" not a sharp in the case to be found.
Does that fuse mount also have a cover ? Ever see a Class T Blow and send flying sharp ? Hard to do but can happen and NOT pretty ! They are surprisingly fragile too.
SOMETHING ODD ? Different ??
On my cases, the ON/OFF switch is between the display & handle, right below the P- terminal.
