The impossible Gobelpower DIY Kit. Unfinished product or am I just unlucky?

- I really wanted to show you the BEST DIY battery box kit out in the market, using a 200A JK Inverter-BMS, DC circuit breaker and a fantastic quality of material choice and design. At least that was my expectation...
I was always a big supporter of Gobelpower and was very exciting, that they sent two of the new DIY Kit battery boxes with JK Inverter BMS so quickly. Maybe a bit to quick.
So, after making this video, it turned out, they did send me two DIY kits from their first batch to test. They just didn't tell me that🤪
In the next video, I will show you how to build this battery correctly, even though there are still some issues with holes not lining up and forgotten parts not been included in the box.
Well, this video was already uploaded and they have to suck it up for now. I'm sure they will improve and also now have a checklist so nothing will be forgotten any more. And a manual... gosh, how good would that DIY Kit be with instructions how to build it.
Gobelpower DIY Kit. It is a DIY project, so...

Lucky for us and manufacturers in China we have Andy and the 'Off-Grid, Unfinished Product Test and Re-Engineering Garage' to sort it all out.
but they are selling that cases already, and people pay a lot of money for that.
when i compare to PC cases, you get for 100bucks really nice quality. and then look at that
I hope the ones sent out are of better quality.
@@OffGridGarageAustralia Well if not Andy, it makes for more informative and interesting content for us.
Perhaps I missed it, but did you remove the foam between all cells? If not, it may fit without the foam. Leaves all the other misfits!
Thank you for your Time and energy,
Gobelpower should have done MUCH better but hopefully this video will encourage them to step up.
On a positive note: you can't accuse Gobelpower of _influencer bias_ by sending you perfect equipment and dumping bodgebuilt rubbish onto the rest of us. And nobody can accuse you of being singled out for special treatment.
So that deserves a couple of tadpoles if not a whole frog.
Seems to me that Gobelpower only changed the Front- and the BMS-Mounting panels but did not test at all if all cables etc fit together! Thats indeed is bummer! That is low quality in product design.
Regarding the PCBs. The older Boxes never had PCB. The steel bars are cable trays only.
The squishy caps are to cover the Plus- and Minus pole of the pack.
Flexible Busbars did come without holes for the BMS cables. Drilling and threading them with M3 holes is easy and works perfectly.
So it‘s more like a real „DIY kit“ and not a ready made kit just to assemble. 😂
I‘m pretty sure we will see a V2 Version of this kit after your review and I‘m sure it will come with a proper manual and all features you will request!
Cheers Jens
sieht so aus, als ob China auch die Facharbeiter fehlen.
Hey, it's Mr Blue Sky from Sunny Australia and Sunny Andy. So now you are Mr Blue Sky from the ELO song. Solar panels, batteries, and everything connected. Critical thinking from the knowledgeable and cheerful expert down under. Will not be long before you have 100k, very much deserved. Thanks.
Thank you. Yes, blue sky again today after a lot of rain yesterday.
Seems like a similar experience to the original Seplos Mason box, lots of issues in the early versions which eventually got sorted
It's still slightly shocking that Gobel didn't look through the complaints about competing battery boxes and fix the issues. It's like they have to reinvent the wheel every time
Thanks Andy for taking an early look at the box and giving good feedback to Gobel. It's great having people like you to act as a bridge between the customers and manufacturers
It would be nice if they'd stop using early customers and reviewers as alpha testers though
At around minute 10:35 is where the mini mill is coming in handy to mill slots. At minute 17 more milling and threading work! Gobelpower sent you these Alpha DIY boxes so you can tell them what they need to change. Perhaps the next shipment you will get a Beta version. In a few months time they finally can release the final product to the public. Well done Andy for making Gobelpower a better product!
Still haven't got a mini mill. I had one in my hands the other day when at the hardware store but put it back in the shelf...
Yeah, they didn't tell me, these are pre-production kits.
Just want to say thanks for all the information i get from you. I appreciate you mate
There is a hype now of building these boxes. Many companies comming out with their copy stuff. Some fit more or less good. I bought a box named a pexium. I am lucky, all fit inside with bussbars and the 3mm conection in the center for the balancing cables. Also these nice distribution bar for the balancing cables.
Thanks for all the input you give and great that you can make it work with family life / normal life. I am a bit opposed to the square batteries vs round batteries which are compressed to a certain extent
Typical case of banana battery. Matures with the customer. 🤣
Thank you very much for your honesty.
👍👍
...and the manual needs to be done DIY.....😉
It's not a kit, it's a puzzle.
Best wishes from the german "Betriebswirte and Fachinformatiker brotherhood".
That is an insider joke for those who are watching his german channel too.
I have the EEL v4 box with the new jk-bms for 2 months now. Also with the 304 double terminal cells. Everything just fitted like a charm. Very happy with them.
Great, thanks for sharing. EEL is doing a great job with these boxes.
Thank You Andy, interesting, I was told that the Battery kit was not available anymore. I asked Gobel Power via their site but got no answer. Happy to see that it's available again.
I experienced Gobel Power as very reactive, sure they will help You too.
Good luck and I hope to see the next video soon ;-)
I will assembly tomorrow my EEL horizontal box with jkbms (v4) without screen.
I’m so exited to know what do you think about that news versions. The vertical model with jk seem to be cool as well.
Thanks Andy to get time to get back to manufacturer all the problems.
With your job, yours products will be shipped after quality control.
Hi Andy, maybe try the Frankenstein cells in the box instead considering they are true 280ah cells
Love your channel, taught me so much
Glad you do what you do, Thank you! Had similar experience with Basin Green. Apparently thier are more than one alpha testing center on different continents. Stay charged, 2x EEL v4 inbound.
Hi Andy, did you remove the EVA tape from all the battery’s? It looks like if the battery’s have only those separators in between should make it fit the compression plate much closer and the rails holes would line up. Cheers and good luck on the build.
That's too bad! It's a good looking and strong box. But it appears there are too many problems for now. I hope they get those issues fixed!
Mine was shipped on the 13th, the same day as your community pics. I just asked them if my box will have the same issues as the ones you show in your video, with a link to your video.
They just reply to me saying they will resolve any issue the users have, not really saying if the actual boxes they are shipping are like this one...
Ah, great, we will see. They are very concerned about the quality issues I have shown in these videos. I'm confident, they will get it right!
The jkbms sounds good!
I ordered 3 assembled batteries with JK BMS and Hithium cells. Gobel already told me that they come without LCD, but end of May they will be able to offer the 3.2 inch LCD as well. They said there is not enough space for the 4.3 inch touch screen. I still must wait 3 or 4 more weeks to receive them here in the Dominican Republic. Keen to see how they made the build.
I'll open the pre-assembled battery from Gobel today to compare this with the DIY kit. It could be exactly the same.
I'm not too fussed about a display and would hardly use it.
Thanks Andy
Interesting. I have been considering the exact same DIY, but not so much at the moment.
If you still have the Pre-Built Gobel setup in the exact same (in theory) case, do you think you could do a side by side comparison of both chassis' and setups(ie measurements etc.)?
I would be really curious to know the differences between the two.
Hello Andy,
no manual seems to be the chinese standart for new products. 😉
The EEL V4 has also a full backplate. All parts do line up perfect.
Their cables are easy to bend, because they are thinner - much to thin for my taste.
The EEL flexible cellbridges have two M3 threads.
I have made a lot photos of the EEL V4 during build. If you like, i can send them to you.
Thanks for sharing. Yeah, the bridge between cell 8 and 9 has two balance cables connected when using Pace or JK BMS.
Thinner cables are not great, but on the other hand, I would not mind as I will not pull more than 100A from such a battery anyway.
Hey Andy, thanks so much for this one Looking at a Gobal purchase myself but with the PACE BMS. What would be fantastic is to hear from you about regulations and certifications needed to use these China boxes in Australia completely Off Grid. I am in country NSW and very very close to buying one but the legalities are holding me back. I know the EVE cells at least have the IEC62619 certificate but the Gobal products only have full IEC62619 cert on the Premium fully assembled model and not on the Standard or DIY model's. It would be really nice to know what you can share on this. Cheers
I purchased 2 DIY boxes with their Pace Bms a little while back, and at least i got non flexible busbars with the holes for the Bms and the active balancer pre drilled.
No manual for me either, but there are some documents on their portal for the Bms to battery connection at least.
They did have some creative cabeling on my boxes as well, but it worked ok when i got them to explain how it was suposed to be connected 🙂
I just managed to get my old cells into the box, by changing some of them for some spare cells ( yes, not ideal).
They had managed to miss sending me the external battery cables that was in my offer, as well as some of the screws. They imidiately sent me the cables when I noted they were missing, but I am still missing screws 😄.
Another item that was not perfect wasthat the heltec/Neey active balancer that I purchased with the the boxes did not have any proper brackets for fastening them.
The batteries does seem to work just fine but it was not quite the easy DIY experience I had hoped for.
The support from my sales contact on the other hand was excellent!
Every time I had a question she checked the answer internally and got back to me quickly.
I did also sent them feedback on the missing manual, and that their battery box was a bit more DIY than was ideal for a DIY kit. 🙂
Perfect. Thanks a lot for sharing your experience. Great to hear their after-sale support was good and you got some help when you needed.
I just recently put together 6 gobel diy kits. With the pace bms.
You have the main positive on the wrong side.
And it works best with the top wire on the breaker to loop towards the front panel. And the to the terminals.
Also the rubber covers are for the main positive and negative, of the cells.
The newer 280 cells that test over 310 ah are getting thinner every day. I needed to stack up close to 10mm of pcb board just to make the cells contact. The pressure plate. So maybe the modified the newer kits to make up for that.
I do wish they would use pcb balance leads. Or at least trim the excess wire. And of course in this case add bigger terminals to fit over the 6mm bolt.
I im currently ordereding 8 jk kits and cells.
I've also recommend they use adhesive pcb board on the bottom sheet as it seems it could slide off to the side.
Keep up the great work.
Cheers Elias
Hey man. Good info for me there thanks. I am very close to buying one of their PACE BMS diy models too with Eve 304 cells hopefully, the new MB30's have ran out of stock everywhere. How have you found the PACE model, be great for some real world feedback thanks. I am not interested in the JK model as I don't have a good feeling about the company in general and after their unforgivable dangerous update a little while ago well need we say more.
@MrMandala1111
The pace bms seems to be good, so fare. It has a couple of quirks to do with the optional internal heater.
It will only turn on if the battery is charging, and it will only charge if it is warm enough. So, if the battery falls below low temp charging disconnect, it will need to be warmed up with an external heat source. Also, there is no bluetooth app, and the soc, Volts, and amps are not readily available on the display.
Hello Andy,
Cables are fine for the Pace BMS. But, it's a bit hard to put All of them.
I don't have flexible busbar and I had to drill and tap in to insert a screw and attach bms and active balancer cables.
It's a DIY box, right?!😆
@@OffGridGarageAustralia 😜
I have an EEL battery box with the JK and the cabling between the BMS and the battery is also a nightmare. At least your cabling looks like it has some girth. I have 2x10mm2 between the battery and BMS and BMS and negative terminal. The positive is 20mm2 to the breaker and the positive terminal but it's a tight and tortured path. What happened to custom-made flexible busbars. Also, the EEL box has a solid bottom plate.
Andy..Try KESHEE diy jk BMS battery box. 😊
I'm your big fan.
3:52 : the Seplos Mason V3 box has a continued back plate too now.
4:13 There is also apexium who sells "seplos like" diy kit with the jk inverter BMS + screen in the front plate.
I own last version of Seplos Mason and Apexium boxes (with Seplos 2.0 BMS) : they are exatly the same (just some differences in screws for the top plate, and different busbars)
I ordered one of the new apexium with jk bms, I will let you know when I will receive it but I think it can be one of the best diy kit : the seplos mason good construction, and the jk inverter bms with a good quality frontplate.
Man, the market is full of these DIY boxes. Search on AliExpress... so many different boxes now. I think the Mason was still the first on the market and is also still the best, most thought through with a perfect one-page manual.
Watching the part about the rails I had the same problem as I used EVE 304AH cells that have been used for 8 months with no compression and some had small bulges so it was a squeeze to get in. I had to drill holes in the rails to line up with the holes at the end as the compression plate was not in the correct place. Your rails seem to be shorter than mine. They seem to have changed the end bit as the thread holes were in top.
The rails are just not long enough to stretch. I have found another workaround now...
@@OffGridGarageAustralia Good. Did you take off the foam from both end cells?
will the jkbms work in parallel with pace bms? And can you daisy chain the rs485 between them.
thanks for the duck alert!
I really would love you to build/ test the "Apexium" DIY Box (from eg. Docan Technology (shenzhen) Co., Ltd.), just to get your verdict on it.
Moin Andy, last year I build 2 /Seplos/mason Boxes with EVE LF280K Cells and the compression plate works fine. Now I build the third one with new LF280k HSEV cells from Gobel and I had to add a plate to get the cells compressed. Are the new cells with octagonal contacts 1 - 1.5mm thinner than the old ones and Gobel use them for his Boxes to design their case?
I have the same experience
If you change the polarity direction of the batteries, you will probably have enough space to mount the cables. So the circuitbreaker cable will not overlap with the cables from the bms.
I have always wondered what happens to cells that go from compression to uncompressed back to compression again, should it be dine at low voltage or does it even matter once the expansion has already happend.
Do you have the negative lead from the bms connected to a positive terminal
You could screw up your existing GobelPower battery box to can see how the connection cables are to be used.
Uh-oh. I ordered the kit and the batteries. I am getting the PC-2000 BMS. I am expecting an opening for the display.
I got an email that the cells were shipped on 4/28...not sure if the shipment also includes the kit.
I am in Northern California and, according to the tracking, it has already arrived in Southern CA.
I just got my batteries and my black DIY kit today. I ordered the PC-200 BMS. The front frame DOES have the proper cutout for the display. I ordered the MB30 306AH cells. These came with single 6mm studs, unlike what was reviewed in the video. We will see what issues there are when I begin to put it together. There were no instructions that I saw, although I did not look too closely. I will report back when I begin to dig into it.
Can we have a white DIY box for JK BMS that doesn't suck?
I ordered 1 Box to germany and it was supposedly shipped on the 14th. I was also hoping to get a quality box for the JK BMS. Very much looking forward to your 2nd video then...
Da steigt die Vorfreude oder? 😂
Aber hallo… 😢
Hier das gleiche. Meine Bestellung der Box soll ebenfalls am 14. verschifft worden sein. Man darf gespannt sein, was da kommt. Andy wird uns im nöchsten Video ja zeigen, welche Lösung Gobelpower vorschlägt ;-)
Mine was shipped on the 13th to Spain, what a mistake it seems to be to order this
Meine Box will sich lt. Tracking nicht aus China heraus bewegen. Bin gespannt ob ich die gleichen Probleme habe. Dann wäre ich mit meiner DIY-Kiste nach meintechblog besser gefahren. Wollte diesmal weniger selber bauen...
Well, mine is still inbound from China and I am almost certain all of us having ordered these DiY boxes will run into the same topic, since Andy is the Alpha-Tester and they probably have not had any reason so far to modify it.
What is really frustrating, these boxes are not cheap a all. We can only hope Gobelpower will support us fixing the issues.
I'll make sure they will support us and have a good after sale service!
I bought 2 of these diy boxes with jk bms, just received tracking number today, I hope it does not come like yours did.
I would think, they are OK now.
Would it work better with lower capacity cells (except for the balance cable issue)? Perhaps the box only works for some cells.
They all have the same dimensions from 280 all the way up to 320Ah. This is what the box is designed for. I don't mind the gab at the compression plate, they just need to rework these metal bars above the cells.
W for white.
You're onto something here 😉
I definitely prefer to have the LCD display to quickly check values. You always need options and I get sick of using the app all the time.
Hi Andy
I have small solar off grid system
Having a 3 pin ev Charger which can set from 6-13 amps
Its working perfectly from grid
But not from my off grid Inverter
Inverter is 3.6 kw battery 10 kw lifepo
I can run other appliences easy over 2kw load no problem
If I Connect this Charger its Connecting turn on for 1 sec and turn off
Then turning on 1 more time
Turn off again and shows Car fully Charged
Could you please help what could be The issue I am from uk
Many Thanks
Etele
I have to correct you after 8 minutes of this video. I almost never look at the displays of my 4 EEL boxes when communication with the main system is established. It's ok that you need a laptop for installation. After that I no longer need a display, even though it's nice to have one to press and enjoy.
Yes, correct. As I said, it's just a nice to have feature but not really necessary.
At 16:20 ... could this box be for a smaller battery? Maybe 220 or 230 AH cells?
All prismatic cells from 280-320Ah have the same dimensions.
230Ah cells are a lot smaller already, they would not fit in this box without a massive plywood base.
Kleiner Tipp: Ich würde die Zellen andersrum rein stellen, dann geht es sich mir den dickeren Kabeln auch besser aus und in die Zellverbinder Löcher bohren und ein Gewinde rein schneiden für die BMS Kabel, das ist in kurzer Zeit zu machen.
Balance cables - you could cut off the 3 mm ring lugs and install new 6mm insulated lugs...
Are the fiber plates included in the kit? just try skiping the plates between the batteries and see if it fits might solve most off the problems, we never used to have plates between the batteries, mine is fine with out makes sense to have them next to steal structure, should not be needed between batteries
I was reading a thread on DIY solar forum today, about a house that burned down, general consensus seems to be a direct short between two cells as there was no fibre insulation plates between the cells - it wasn't a thing when he built the batteries 3 years ago. His was fine also, until the day it wasn't. Yes the plates are included in the kit.
@@TheRonskiman makes no sense that this can happen the hole point of the case is to protect the sell, not trying to argue the point just saying, one possible case dos not make it fact
@@OskarHartmannsson The whole point of the case is to contain the contents, the case can be positive or negative, do your own research though.
Oh Andy 🍺🍺
Die flexiblen Dinger sind für den minus und plus pol der Batterie. Schwarz an Zelle 1 rot an Zelle 16.
Da freue ich mich ja riesig auf meine zwei DIY Gobel Boxen.💩 😮 Sollen in drei Wochen kommen. Das kann doch wohl nicht Gobel ernst meinen. 🤬🤬🤬
Dunkelflaute here in Eastern Australia
The first thought that comes to my mind (since it's going to be DiY!) is to throw away the yellow epoxy sheets and use much thinner sheets instead. This way you will gain the missing millimeters!
Who told these have to be original sheets? :)))
No, no, no... Not throw away. Sent those to me for recycling projects.
That won't make up for the difference. I also tried without any epoxy in between and hardly made any difference. The just need to add some long holes on the top rail to support different compression stages.
@@OffGridGarageAustralia Strange, I thought these resin sheets were about a millimeter thick.
So in these circumstances, all that is left is a precise file and longitudinal sawing of the long holes. So that they become "long enough". I hope the brace is long enough. :)))))
👍👍👍
is the box a parallelogram? get a square and check!
Why are you pondering questions which should be in the Assembly Manual?
Gobel now on the Seplos Mason trip with the a new creme design instead of plain black ?
There is no manual cause they are expecting that you will make a proper video and therefore they think they do not have to spend the money & time for a proper manual.
Same for Seplos Mason Tower , that creme white one, which also had arrived without anything.
People think that if the products are expensive, then they buy quality goods
I bet they designed the battery box for 100amp cells.reason for build not fitting well
I'm difienitely about to buy a die cutter and a lasser welder and start from scratch
you have the wrong polarity on the BMS, you have connected the negative of the BMS to the positive pole of the cell.
Maybe it design for 280 only.not for 304 battery..you should try with 280 battery.some manufacturer don't make for 304 battery coz it still new but 280 had more user right now
Heya, I'm very sorry but what is that with these company they don't test there product to see if everything fit's. wel lets go to the next vlog to see your diy solusion
Maybe Try with 280ah cells?
They have 100% the same dimensions.
@@OffGridGarageAustralia oh okay 😅👍
⭐⭐⭐⭐
just Macgyver it Andy ... use your 3d printer to make adapter brackets
🐸🐸🐸
Great review. Maybe i should order the battery including EVE cells. €2.300 instead of €1.800 for DIY. Or 20% for avoiding troubles.
And I have a 15% code on my website for the Standard edition of their battery. Yeah, the price is almost not worth building it yourself.
Yet another add to cart, but by the end of the video remove from cart!
Been nothing but donkey balls lately!
Mybe The 280 Ah Cells are a tiny Bit smaller. As Gobel subscribe The Box for 280 Ah Cells
Like# 1
there is not enough space between the terminals and the case on cell 8/9, they are way to close to the case i think.
i mean, look at that 15:34 , with busbars installed they are near TOUCHing the CASE !!
question: arent they ashamed to send you such a garbage? i really want to build a diy battery, but when i see the boxes .... no way, it's a serious savety issue to have something working at home.
maybe they really do not want to sell them seriously, because build boxes are more expensive, and they can earn more money.
but, i rather would buy from PYTES
Plenty of space for cell 8 and 9. they cannot touch the case under any circumstances.
Well, they told me, they will send some boxes early. They just didn't tell me it's their first batch or even first two boxes...
I believe I know why those brackets don't fit.
The manufacturer should tell you what Size AH batteries is needed. Your 300 plus AH batteries are too large.
They should make the box universal to use any AH batteries.
All your Delevery need to be on wheels😂
The box is designed for 280ah cells
The 304Ah ones are the same size
@@niktak1114 Thanks, mine must have been a little bloated.
Its as if ten guys designs fifty different components of the system on a computer, not a single one of them speaks to each other, and they are in four different countries and they go straight to production in 17 different provinces without ever even building a single prototype.
Not good got 2 of these incoming in the next 2 weeks.
Abc avoid to buy Chinese.. but in this case we do not have solar systems..😂 a bit shitty..😂😂😂
Zweiter !!!!
Hi Andy, I hope you got my email with gobel pdf’s
Brutal
made for 280ah cells not 304ah
You could screw up your existing GobelPower battery box to can see how the connection cables are to be used.
