Be aware of these options, features and flaws of DIY Vertical Battery Boxes. A comparison...

In this video, I'll go over features, options, designs and flaws of these vertical batteries we had a look at over the last few videos. It's not a comprehensive comparison but I show you some of the main points to look at if you are interested in these DIY-Kits from EEL, Seplos and others. We compare design, terminals, safety, mounting options and have a look inside to inspect bus bars and of course the compression of these flat laying cells. There is a lot to talk about and to show.
This video is a guide to make you aware of some of the differences and what to look for when you plan your own battery project using these boxes. I think they are fantastic, and I really like building them. They come with all the parts, BMS and even bus bars and look professional afterwards.

[@BrindleBrown]

I really enjoy your channel and I have learned so much from your videos! Thank you very much! I feel like the battery box makers are building battery boxes for reviewers and not for my needs. I wish someone would build a simple battery box that fit 16 EVE 280/304 cells, provided a compression plate, and left enough room in the rest of the box for me to mount a BMS, a fuse, and a breaker. I wish they did not have the terminals on the outside of the box, since after the system is installed, I don’t want any exposed wires. That means all the box should have on the outside is a small door to access the disconnect breaker. Everything else should be inside the box with circular knockouts to allow me to connect conduit to use to run the wires to the inverter or main busbar. I don’t need DIP switches, Ethernet/CAN/RS485 jacks on the outside of the enclosure where they are susceptible to damage. The designs I am seeing do not make any sense whatsoever for safe, reliable residential installation. And it certainly doesn’t need wheels!

[@OffGridGarageAustralia]

The Gobelpower case is designed to go into a server rack for example. That would eliminate all of your concerns. Having doors and breakouts everywhere just makes the design more complicated and the price higher. People will complain again😉

[@maxtorque2277]

Notes on cell compression: Compression absolutely reduces cell ageing during high current cycling by a significant amount, but it's is pretty unlikely in most static storage scenarios that you will be anywhere near a "high current cycling" type regime! However, a primary reason to compress your cells anyway is to avoid stress cycling on the terminals and bus bars! As the cell changes temperature and SoC it changes volume. Under compression this volume change is significantly reduced, so as a result the bus bars and terminals that effectively span between the cells experiences a lower stress. So the more: 1) you use the full SoC range of your battery 2) often you cycle your battery 3) stiffer your bus bars are 4) the higher currents you pull (in either direction) then the more you should consider compression. It's not a Black / White situation, but it is important to consider ;-)

[@OffGridGarageAustralia]

Yes, compression is beneficial for the first few cycles and high C-rating.

Regarding the Gobel Pack: Newer Packs (I've received mine just three weeks ago from the germany Warehouse) don't have a Fuse anymore, just the big Circuit Breaker. And the pack compresses the cells far better because the frontplate has bent edges which results in a far more rigidity of this plate. We also noticed this on a pack we unfortunately needed to disassemble completely because it suffered physically damaged cells due to improper transportation.

[@OffGridGarageAustralia]

Thanks for sharing.

@@OffGridGarageAustraliaAndy I did have to ask for the Epoxy sheets but they sent those for free. My cells were a little swollen so it was a ‘bar steward’ to get the compression plate on. I had to buy longer bolts. The instructions weren’t great and you have to download them. I recommend you tell everyone (on your web page with the link) that the pace BMS was set to 3.7v cell protection voltage out of the box. I didn’t get around to programming the bms until after a few weeks of operation so I hope I haven’t damaged any of my cells. If fact if anyone buys the gobel power battery please check the OVP figure. Surely Gobel/Pace should know that it should be set at 3.65v (unless they assume we will buy LiOn cells? But they don’t sell them anyway!

[@matthieusevestre6401]

Just checking the video. A quick comment (that has been possibly done by previous people): the new Seplos case design comes with an intermediate horizontal plate (still, not vertical central one) that helps to compress a bit better. Also, it comes with flexible bus bars. No circuit breaker nor epoxy protection on the back of the front plate. Comes with BMS v3 and the active balancer board as well. So good evolution compared to the one you got, Andy. Manual remains crap ;)

It's not recommended to use a fuse after 8 cells if that is what you guys are referring to. In case the fuse blows, it leaves the BMS with 2x 8cells but no connection in between. Some viewers have reported that this caused the BMS to fail/break.

[@enyasalida3736]

As far as I followed the discussion at least in Germany, many people seriously doubt that any other orientation of the cells than with the contacts to the top would kill them faster as you can watch it. Obviously the case builders are not that afraid? A common set are motor homes based on Fiat or Citroen chassis where (lead) batteries are often placed beneath the front passenger seat with less then 180 mm in height. Its really hard to find LiFePO4-cells that fit in there upright.

[@OffGridGarageAustralia]

Well, these people in Germany should watch the Zerobrain channel where Markus explained the orientation of the cells. Don't know why there is still a discussion about it. It was also mentioned on 'Der Kanal' a while back and confirmed by EVE.

[@bjornbaumgardt8030]

GG you are a really ALMAN i love it😆 greatings from Germany

[@Michael-AUS]

The compression of cells in a vertical battery would be uneven between the top cell and those near the bottom, due to the weight of cells that are resting above them. In other words, 300kg of force on each vertical run would mean close to 340kg of force for each of the bottom cells. So, I guess that some allowance would need to be made so as not to over-compress and potentially damage some of the cells.

[@OffGridGarageAustralia]

kgf is not the same as kg though.

[@vinny143]

[@Doctorbasss]

There are some current leaks between the cell terminal and the aluminum case of the cell sometime. The very thinny blue wrap plastic around the cell is not resistant enough to protect the cell aluminum case from electrical contact.. Even more on the edges and corners where there are concentration of forces. So it can happen that without insulator material such as polycarbonate or G10 or FR4 sheet, that two adjacent cells make electrical contact together thru the fragile blue plastic and the current leak would unbalance thece cells over the time and make the BMS work harder to keep up.. This have been discussed a while ago already. It is preferable to use insulating sheet between cells to avoid these problems. Also compression reduce internal resistance and preserve the anode and cathode current diffusion more uniform inside the cell. over the lifetime of teh cell which lead to better overal SOC. That's why automotive manufacture all strap these cells under compression. Making the Electro-chemical Impedense Spectroscopy test of the compressed cells vs uncompressed will tell you that too.

[@smartazz]

Thanks for all the info. I’m about to build the seplos 280L with 2A balancing, I might even video it and put it on KZbin 🦮

[@karisianschwermer6464]

After all these years, I still have no understanding of this compression issue. In the first few cycles, gas bubbles form, causing expansion and thus outward pressure. If the cell is clamped with 3 kN, the back pressure prevents the cell from expanding and the gas is forced outwards. So far so good. But if there are 8 cells in series, the pressure of the individual cells should add up. So either the 3 kN would no longer be sufficient or the pressure would be so high that the cells would be damaged. The data sheet states that the cells are damaged from 10 kN.

[@noxikid]

No, the pressure on each cell is the same as external pressure you apply. They are not summing up as a voltage

[@OffGridGarageAustralia]

The gas bubbles block the flow of lithium, form a layer and finally a solid barrier. You lose capacity with these barriers. Compression is only needed for the first few cycles. Not sure how many but I would say 20-30 will be enough. On the other hand if you make the effort and compress your cells, you won't take that off any more, do you?

[@odoohub5010]

At 6:43, is the bms not enough to protect the battery from overcurrent situation? Why do we need a fuse or circuit breaker, when the bms does the job already?

[@OffGridGarageAustralia]

No, the BMS will not be enough. There has to be a mechanical safety device, either fuse or DC breaker. The BMS protection is in addition to that.

[@leeshively669]

Andy, thanks for the vertical battery review, the QSO is the same BMS as the Basen Green. Code is 888888 to unlock the BMS, here in the USA it talks under the Narda protocols (non can) Rs485.

[@dc1544]

Compression only makes since if you have them in an area where it gets hot enough. As we all know heat makes things expand. Also if you need to go over 1C charge/discharge. EV's can achieve 5-10C so then compression is a must. I have mine in my cement basement so temperature stays 50-60F 10-15.56C year around. I never go over .20C since I have 4 banks and 2 inverters with my loads and charging. So in my case I do not need compaction. Also in a moving/vibrating vehicle I would use compression even if I didn't go over 1C.

[@OffGridGarageAustralia]

Compression is only needed for the first few cycles to remove all gas bubbles... or if you have higher C rates.

@@vidsbymoach I would not use anything else than a JK any more for a new build. If BD or PB series, they just work and with the active balancer, it's a no brainer. With any other BMS you have to install a separate active balancer and control it somehow, unless you have very high end batteries which are super matched. But once they age, you will most likely need an active balancer anyway.

[@vidsbymoach]

@@OffGridGarageAustralia hi again! This = B1A20S15P should be the right one…. 1ampere active balancer 150a current and 16s. Any further comments? Br

[@kajakfahrerr]

Gobel provide a diy kit for 290A cells, but not with the huge circut breaker, sadly ... and i think without the nice compression like in this big kit

[@boerbiet237]

Hy Andy do you have any information about Enwall/Encap battery systems? It has unique specs, for degradation and temperature tolerance. Also DOD is high, I would apreciate your thoughts about this battery. Thanks for all your efforts on your chanel

[@patrickcollins7030]

cute doggos

[@OffGridGarageAustralia]

They are. Usually no allowed in the garage.

[@williamirizarry1113]

Price, free shipping? available in U.S.?

[@peter572]

In a vertical layout, the bottom battery is compressed far more than the top one due to the weight of the stack on top of it. According to specs, over compression may shorten cell life. What are you thoughts on this please?

[@gregbell4951]

Do you sell off old units after your reviewed? I'm looking to buy/build vertical battery to replace my LG 10kw, chasing a box and 15+kw batteries. Great Show keep up good work!

Hallo Andy, das Gehäuse ist auf der Gobelpower Webseite unter - Spare Parts - Gobel Power 51.2V 280Ah Battery Case Kit zu finden. Es wird aber nicht beschrieben, was alles geliefert wird, also ob nur das Gehäuse oder mit BMS, Active Balance, Circut Breaker und Kabeln.

[@Kregorius]

If I Googled the kit there was a video of how to build the kit. I would assume it comes with all the bits and bobs like the other kits. With active balancer and all. Somebody else has to confirm if it's correct.

[@OffGridGarageAustralia]

Yes, got it now linked on my website and updated the video description as well. Thank you.

[@legominimovieproductions]

Have you heard of the apexium diy kit which came with a horribly wrong manual that led to a near battery meltdown (as the busbars/fuseholder heated up beyond good)

[@OffGridGarageAustralia]

Never heard of that kit before...

[@SetitesTechAdventures]

Can you talk abotu how much that compression is in real life? I had to get a special screwdriver to torque because people opnline said 300kg of force is only like 8.25 inch lbs which feels so weak. The problem with seplos is that they used a flat sheet to try and compress but flat metal has very little strength. Even with a third rail it wouldn't matter as much. EEL and QSO both add angles to the sheet which is necessary to prevent bending of a metal sheet. The fact seplos doesn't have angles on their compression plate really makes me doubt their engineering knowledge. What's that horror music? It reminds me of an episode of Star Trek.

[@OffGridGarageAustralia]

I'm not a compression guy, so can't give you an answer how much 300kgf is. The forums are full of people showing their battery builds with springs, rods and plywood. EVE does nto even use the word compression but only talks about fixation. Here is the song: kzbin.info/www/bejne/op2ueaKhaZeVlcU

[@MeisterQ]

Thank you for the Video. I really like the gobel Case but.. i cant find any without bms and without cells. I got everything here already and only need the case. Any ideas?

[@TheSpidertop]

Hi Andy. What about cell position inside? They are horizontal. No issue for lifepo4 cells?

Just checked the eel battery eu warehouse. The vertical battery oage has Off-Grid Garage-Andy Review in the bottom. Only pictures of some random hairy dude though, no video it seems.

[@BobboNaught-YT]

I don't understand why these builds don't meet all the requirements. Are they not planning on warrantying them if they fail? Or do they plan on blaming the owners for how they DIY-assembled them? I'd be concerned about them if the cells expand without flex bars.

[@OffGridGarageAustralia]

The answer is: costs!

Hi Andy, Could you please help me with QSO bms default password? Can't find it anywhere)

[@teardowndan5364]

Having two +/- terminals on each battery is unnecessary for daisy-chaining, just stack two ring terminals instead of depending on additional intermediate links through the battery.

[@OffGridGarageAustralia]

Yeah, true...

Horizontal boxes are the best way to go, I don't understand the infatuation on vertical batteries.

[@OffGridGarageAustralia]

If you have not enough space for a horizontal installation...

[@thomasschwarzenberger8943]

Hi, does the Peter inverter communicate with the Cerbo GX?

[@Kregorius]

This one is a doozie: gobel power battery can lay flat or stand up. So what exactly stops us from taking some "horizontal" DIY battery and standing it up like vertical one? The footprint and dimensions are determined by the call size so it should be somewhatvthe same in both types. When i look at this lineup with the free willy cable management... i dont want to have comms cables coming out from the front or sides. Same with the battery terminals. The gobel power has the right idea about all the connections and terminals on one end. So why not use the regular horizontal one and stand it up? Not having the wheels is the inly difference? (Bit room limited with my options.)

[@OffGridGarageAustralia]

Yes, theoretically, you can just mount any battery upright. Put some wheels underneath and BOOM!

[@Angelorademon]

Not every horizontal case has a back that is strong enough to allow you to use wheels or supports on it without bending it. After all, the weight of this box is about 110 kg.

Hello, I recently built two Seplos vertical 280ah battery with 16 cells, also added Neey active balancer controlled by a voltage controller. Everything worked just fine for aproximately 3 weeks, but now I see that cell no.9 in my first battery is running against the other 15. In charging it has a higher voltage by aproximately 0.2V, but in dischargin it goes lower than the other cells, also by aproximately 0.2V. By human error, I did not set the voltage controllers at the same settings on both batteries, the one that still runs fine was set to start the balancing at 54.4V, but the one that now has this problem was set to start at 52.5V. I now hope that my problem is only related to unbalanced cells in the problematic battery. Can someone please advise me on how I can rebalance the cells now?

[@dc1544]

I would not daisy chain more than 2 batteries together. Seen really bad results doing so. Seen batteries pull a lot more from different batteries in daisy chain. Doing 2 then to busbar would still keep them even. Busbars from each is still the best way with same length cables.

[@OffGridGarageAustralia]

Usually, people use more batteries to get longer run time for their loads, so the current won't be higher than with only one battery. However, if they use more batteries to power more load, it's a different design. I have had 8 batteries in parallel to my battery shelf with all sorts of cables connected. Not a single issue as it just extended my runtime. In fact, the current rating per cable/connection went down significantly.

It's a serious topic though😬
