YEP "just 6 more".
Do we need to start a 12-Step program ?
For fellow addicts... A Teaser, just testing a shelf system for my refreshed bank. Looks cool but won't do it...

Lol, I got those shelves. That would never work. Its sagging with just the empty boxes.

That looks awesome Steve but I think Mr GobbleBottom might be right. I hope you can make it work.

Can that shelving unit handle that weight? If one of those legs buckle....
Edit, read further on, nevermind.

Well that is HOPIUM and not reality obviously. The photo as stated is to test - a fry run and well it's a FAIL ... It's really easy to "rock" the shelf, not that stable... so destined for the toolshop.. Solution hunting still underway.

This might not be the size you want but 800lbs per shelf capacity. I have some of these in my shop with casters. Heavy duty but not cheap!
Two-Shelf Wire Shelving Unit - 36 x 18 x 34
Recommended for garages and storage rooms where space is tight. NSF certified shelves adjust in 1" increments. Assemble in minutes. No tools required. Open wire maximizes airflow, reduces dust. Optional 5" polyurethane swivel stem casters add 6" to height. Add-On Units and Wire Shelving...

I am looking forward to seeing your setup. Are you using closed loop BMSs?

I can if I need to but no not worried about coms, I plan on a smartshunt per 4 batteries to only monitor each 1200ah bank at this point. This system so far is backup only no solar.
Can’t wait to see the custom cases, it will be nice to have two 12 volt 304ah in one small box. I will have 2400ah portable for the work truck in four packs.

Picked up an Adjustable 5-Shelf Steel Metal & Wood Storage Rack / Shelving Unit, 41 x 18 x 72-in, with 5 timber shelves that are adjustable and hold a total of 4,000 lbs (1,814 kg). These are Steel & Wood (not particle krud). It's too high so I will have to cut it down to size. We are assembling this shortly. SALE Priced for $120 CAD.
EDIT - UPDATE. New Shelf is together. WAY BETTER !!
Turns out I can use 1/2 of it which gives me a total height with space etc @ 42-1/2" to the TOP of the cases. This is also including a short double shelf on the bottom which lets me put a sheet of foam insulation between them to prevent the floor acting as a cold sink. The Hammertone finish etc also LOOKS
hehehe This unit is also 41" wide (within my 44" max limit). With everything on it, Maggie & I shifted it to see if there is any Racking and NOPE, nice & snug. I stood on one of the shelves and while I'm only 130lbs or so, no give or anything. Fully loaded and also no racking ! NB: This is a 2 person assembly process, tool free except for a needed mallet.This is a Canadian Tire product but for othe fellow Canucks here's a link & for our southern neighbours there is likely identical/similar to these.

No rush S.Davis
I am not making rapid progress myself.
I just try to keep my retired self amused while making my batteries easier for my wife and others to understand.

Doing the same, wife/neighbor kid proof less the retired part, running a HVAC company full time as well.

I am planning to use these Temco Butt Splices to connect my BMS to the battery.
I will cover the splice with heat shrink tubing. What do you guys think?

I have several JK's out there setup like that, see below. No problems with it BUT I did use a Hydraulic Crimper to ensure the best & tightest crimps. TIP: Because the wires are silicone, use Heatshrink with adhesive/sealant, (call it lessons learned).

I know it doesnt matter but I would have made both wires black.

Thanks Steve for the detailed reply and great labeled picture. These batteries are going to be fantastic.
I used lugs and busbars to make those connections before.

I chatted with Amy about a closed loop JK BMS for one of my batteries. I will also order the BMS mounting plate and a new face plate with the closed loop BMS cutouts. She only wants $19 for the two plates and the 200A closed loop BMS (JK-PB2A16S20P) is $112. But shipping is by air so it won't be cheap.
I will get the shipping quote tomorrow.
I told Amy that these batteries need a class T fuse. She thanked me for the suggestion but I don't think she wants to do it.
I will probably have to add them myself. It is painful trying to fit that Blue Sea fuse holder in there.

Small stuff (<2.5kg) and small package size, by air is not as bad as most think. I get things by air if it's small & need it fast and the bit extra it costs is better than waiting 6-9 weeks. Are you also getting the 4.3" screen for the JK Inverter BMS ?

I have 5 of the 4.3" displays to go with my 5 cases. Amy said the BMS and 2 plates weigh 7-8kg. She will get back to me when she has the shipping price

I have Luyuan box as well, the wide version. I picked the 200A JK BMS but received 150A breakers from Amy. I wondered if I should get 200A instead? and does anyone know 200A has same dimension as 150A breaker? cause my box already cut to fit the 150A.
Did you guys change the silicone wire to tinned copper?
Btw, does anyone have better ways to monitor several JKBMS units aside check bluetooth one at a time? Wired all JKBMS to Victron shunt?

A member here wrote a driver that can be installed on a device running Venus OS.
Victron VenusOS driver for serial connected BMS - JBD / Daly / ANT / JKBMS / Heltec / Renogy / Tian / ECS
I have created a VenusOS driver that can talk to BMS/Batteries that has serial communications (instead of the normal CANbus). RS485/RS232/TTL/UART and Venus 2.80+ have been tested. Currently it works with JBD BMS (LLT Power / Overkill Solar) Daly BMS (Daly Smart BMS / Daly Sinowealth based...

The 150A & 200A are the same physical size.
I also got the 200A JK-Inverter models with 200A breakers in all my boxes. Gotta say, my bank is such that no battery pack ever sees such a draw. 6x280AH.
The silicone wire is the best option really, they handle more & use ultra-fine silvered wire. There should be a copper Crimp Ring on the end of the wire to go into the breaker.
Monitoring can be done via the Bluetooth app (great but a PITA as you can't see the "bank at once". The PC app requires one port connected to a PC and there's quirks & foibles of course. Brucey pointed to the Victron driver and other software is being interfaced, so Home Assistant & Similar will soon be able to communicate with these new BMS'. Andy from Andy's Garage has a couple of Vids on the new JK's & Victron interop but I don;t know how current (up to date) they are as JK is continually tweaking & improving the Firmware & Software.

If you'll be able to pull over 150A through the breaker then you'd better get a higher rated one, and it wouldn't harm getting a brand of known quality at the same time. - But - I guess you won't be able to and most likely have 280k / 304's? So 140A / 150A 0.5C rated, which doesn't give any headroom if you can charge or discharge at that current, but should mean your 150A breaker is within spec ish.
Nothing wrong with the silicone wire if specced correctly.
I use Serial Batttery as Brucey linked to, but if you've not got a full Victron system or intend to, just having the SmartShunt on the main negative for all your batteries is a good way to see the key details. I also have the SmartShunt like this, as the JK's can't be calibrated properly ever, especially under 5A or so, they aren't accurate enough, but.. they are close enough if you're not worried about absolute accuracy.
