- Tonight is the Night of all Nights! We're trying to wake up the Frankenstein Battery for the very first time. The Gobel Power BMS will help us to stay in control of the beast. Everything looks good, the weather is perfect and still, the first attempts are unsuccessful! The third and final attempt, however.... and the cells arise from the dead. It is alive!
I went with your suggestion from the last video and used only flexible busbars to connect the cells together. I think this was good advice. I also install the NEEY active balancer parallel to the BMS to help controlling the battery.

Thank you, James.
Love your special effects. Very creative. Thanks for putting in the extra effort.
Thanks a lot Dave. It was a bit of work, but I loved the process and hope most will enjoy it.
Creative. Entertaining. Informative. Clever. Thanks for sharing
Thanks a lot Lou!
This was very entertaining! Thank you Andy.
The day Iâm waiting for the vid release⊠nuttinâ
Sooo scared! đ± He the âstitchesâ will hold Andyđ«Ł Good luck with the testing sequence đ
Seriously, that opening was ridiculous and not necessary, and I enjoyed every second of it.
Thanks for sharing, and as always, keep building đ
Hahaha, yes, it was not necessary but sometimes I have to do it. Getting very serious in the next video again.
Looking forward to seeing it walk... And seeing more on what this BMS can do and what you think of it.
very good one off grid garage!
Great video production. Well done.
Thanks a lot. It took a while... but was a lot of fun
Hello Dr. Frankenstein. Haha. Andy that was a cool startup.
Thanks. đ
That thunder was mocking your mad laughter at the end there đ Hilarious
This project just keeps getting better.
Hi Andy! And thank you again for this video...can't wait to see more!!đđ
Thanks a lot...
Thanks for great content and taking the time to interact in comments!
Love this ......... impressed by your editing......interesting faberoo (as they say in the uk)
Thank you, Richard!
Its great to see you branching out with your video creation and editing!
Yeah, took me a while to edit this all together. But now, back to work and learning more about this battery... đ
Andy du bist der Knaller, I have so fun with this video đ.
Thank you, Frank đ
Congratulations on the birth of your monster. Let's hope it stays tame and doesn't show its wild side. As a "father" you will have to be very attentive.đ
Great Video!
Thank you, Tim. It was a lot of work and fun making it.
Hilarious Andy, great stuff, you didnât disappoint us. đ
Thanks, Dave! đ
LOL - thumbs up for this video came less than 30 seconds in! Love the drama!
Thanks a lot! đ
You should work for the BBC. You produce content that is a lot more entertaining than anything I've seen from the BBC recently.
Thanks a lot Colin, appreciate your kind words and feedback.
Ur Crazy Andy! Love it!!!
I know I am đ
@@OffGridGarageAustralia enjoy ur channel so much
Great Video, great Project! Thumb up while Intro. The only sad is, that there is no Video every day. Very hard to fall asleep without your good night Video. PS: You should take a look at the Deye sun 12k. Very interesting Inverter. Exspecially for your Situation đ
Thanks Sven.
I believe, the Deye 12k would not work for my system at all. I have LV solar panel installation with less than 100VDC. That's far under the start voltage of the inverter. Also the inverter has only 3 MPPTs, that's not enough for my setup. It also does not integrate with my existing Victron system and VRM.
thanks for the help
Love your videos !!! Even my wife likes watching and she knows nothing about batteries đ
Hahaha, great. Thanks a lot and say hello to her đ
The battery is for the real time clock, which is used for the internal logging of the bms. Nice video :D
Thanks, Jens! I wonder how other BMS do this which don't have a battery on the PCB.
Thanks Andy đ
Thanks, Wayne.
You're amazing, I learned a lot from you.
And don't forget: you're funny.

Thanks a lot, Willy
Vielen Dank fĂŒr deine vielen tollen Videos!
Many greetings from Germany NRW.
Thanks a lot, Dirk. Hello back in die alte Heimat đ
Love it Andy, keep up the great content! Still learning off your channel!
Thanks, Tim!
I am sure Andy that you know that the running gag in Young Frankenstein is Frau BlĂŒcher which drove the horses crazy. It supposedly meant glue (in Yiddish???), but whether or not is not really the full issue. Anyway, Andy, I enjoyed your humor but am more eager to see the results tomorrow of mixing and matching batteries, with sort of (304ah/280ah) similar batteries. A good BMS should protect the string. I am sure the weakest 280ah will set limits for the whole lot, but it looks to be fun! Looking forward...
Thanks, Glenn. Yeah, I know the story about the horses... đđ
Working on the edit for the next video. It will be ready soon...
It's aaaaallllive!
The đ±đđđđđđđđđđđ đđđđđđđ đ»đđđđđđ was very "enlightning"âĄïž... it may not walk, but surely talk because of the BMS đ§
Yes, it does talk. And I like what the BMS does. More in the next video...
I'm really looking forward for the testing to see how it works. Above all I'm interested about the cell deviation at fully charge and discharge.
Greetings from Germany
Soon...
Andy , consider looking at Flanged nuts and leave out the washers , the flange give double the clamping area to the post and never have trouble with heat from a weak connection . You can even get nylon insert lock flanged nuts if you have a need for locking in a mobile application like an RV or boat . I use them at work all the time with great success.
You are absolut right, no need for the washers.
I agree, the flanged nuts are much better for a permanent installation. However, we will do a lot of testing with this battery and I have to take off these nuts many times. They tend to damage the ring lugs quite a bit when frequently taking off as they bite into the material.
Hence, I decided to go with the washer, springs and nut solution.
As usual Andy, really enjoy your videos.The fact that this BMS had so many inverter options is really encouraging. How powerful is the balancer of this BMS? How many amps? Is it active of.passive.
The balancer is crap as with all of these BMS. You definitely need an active balancer for that. It will be in the next video.
@@OffGridGarageAustralia I don't understand why it's not possible to add a user-regulated active balancer to these BMSs, and the user would decide, set, or adjust whether they need mA or a few A for active balancing.
I think the two balance-cables for cell 8 are supposed to be on each end of the busbar, to measure the resistance - just like the Seplos does between cell 8 and 9 :)
That's half correct. They are supposed to be one either side of a fuse wich goes in between #8 and #9. If it blows, the BMS will still work. We will get there...
One week ago I got my Gobel Power 14,3kWh Batterie for my Deye Sun 12kW Hybrid Inverter. Hopefully I can connect all the stuff together soon and see how it works. Greetings from rainy cold Austria.
I've tested the BMS now. It seems to be very good. Their battery will get an upgrade soon and I will get mine afterwards. Two major upgrades actually...
As i remember from Jens (Meine Energiewende) Video, Gobel has a MegaFuse between cell 8 and 9. So think the two cabels are to compensate the voltage loss across this fuse.
Yes, that is correct. We will get there...
But then I have to move one cable on each of the sides of the fuse.
One of the best videos u have done plus a dog shot †well done andyđ
Oh, thanks a lot for your kind words!
I can already guess that cell number 17 will have the lowest voltage in this projectâĄđđ»
Hahaha, exactly đ
Or cell 6 đ
@@timjerby5080 Cell #6... OMG đ
That Gobel BMS is $360 USD shipped to USA. I hope the review of it shows that it is worth it but so far it looks pretty interesting.
It is very interesting and has some nice features. It will be in the next video.
Hi Andy ive just bought two of these BMS's and would love a video on all the parameters and how you would set it up for your battery
That could end up in a 2h video đ
I have explained most of them throughout these video series. I'll see if I can fit a 'settings-video' in.
Was wohl die Frau und Nachbarn gedacht haben als sie das irre lachen aus der Garage gehört haben? đ€Ł
I thought the same. Especially, it was late at night đ
Love the special effects and the laughs;
Life without laughter is not worth living, not even for Frankenstein haha!
The Lithium cell battery is to power both the RTC and keeping a log of all the events in memory as you have discovered.
This is I believe a far better & flexible BMS for the DIY's then the other very similar BMS you have shown so far.
Yes, the extra boards and cables are a wee bit of a hassle but it allows you to choose the best place where in your DIY you want those placed. Or perhaps even omit them. Indeed the software is also quite nice.
I did find their documentation on the Globel BMS, very nice!
This will be my go-to BMS if I want to endeavour a 16S project.
I guess no bluetooth (yet)?
PS: I also wonder how you dealt with the total capacity of Frankenstein as there are different capacity cells involved.
I gather you just add them totally and adjust the BMS accordingly?
You're spot on. I'm a bit behind with the videos but have tested the BMS now thoroughly and it is the best so far. It almost ticks all the boxes of what we always wanted.
@@OffGridGarageAustralia No worries, I can fully understand the amount of time it takes to film, sometimes needing to redo takes etc.
We will be patient and btw, you have plenty other videos I also enjoy!
I do want to thank you for the MĂŒller Energy BMS, that now has become my standard for 12v installations (6x at the moment) and works wonderfully well. Truly a bomberfest!
Ruben is a very nice person to work with.
Sun Fun on the other hand is wee bit of a let down, does not respond to email that well, proclaiming issues with spam detection etc.
Too bad, as we wanted plenty of units from them but if they do not respond, we need to look elsewhere or make alternative solutions...
@@InspectorGadget2014 Thanks for the feedback. Ruben will certainly be the right person to support you. I have another Mueller battery review coming up soon...
But Andy we know how much you enjoy wiring stuff and then hiding it đ€©
Hi Andy, intresting expiriment, I wonder what the outcome will be with all the different type's of cells and how the Neey will react to this composition but don't let it walk because one day it will find you frige and BEER
Oh, no, the fridge!!!! đČ
Nice
Admit it, this whole thing is just an excuse to play with your video editor :)

I was worried something had happened while bringing the frankenstein baterry online, since it took few days for the video.
Man, if I would have more time, I would pump out these video like hot cookies...
@@OffGridGarageAustralia no worries, i'm just glad nothing went wrong :D
Hi Andy , this is going true my mind for a wile .. wye donât you not compensate the cells to equal capacity by adding a few small 26650 batteryâs on the top between the electrodes. There is space enough between them.. it wil take a load of the balancing board cells/ ore make up for lost capacity so they come closer together.
The battery is as good as the weakest cell .. pimp the cell up
Thanks Denny. For testing purposes, we can try that and see how it goes. I would not recommend this for a production setup though. It is far too dangerous to just pair very large with very small cells. It needs appropriate protection and planning.
It is like in any battery, the weakest cell dictates the battery capacity.
@@OffGridGarageAustraliakeep in mind that inside the eve cells there are also multiple cells windings in parallel that can variate in capacity .. external adding a no difference if it is the same chemistry
@@OffGridGarageAustralia Like your new project, and I also would love to see this kind of test, but only simpler: I think many people are concerned that one (new) cell isn't as good as the others, or that after some months/years one cell is always making trouble causing low voltage alarms (and therefore significantly reducing the overall capacity) ... The only advice I heard so far is to initially buy some additional spare cells, which cannot be the solution from my p.o.v. Therefore my idea: only look for the weakest cell (i.e. the one which is causing low voltage disconnect), and then add one small 26650 in parallel to it together with a fuse (1.5 A) for over current protection, i.e. something like:
------ 297 Ah cell -------------------------
\----- 3 Ah cell -- Fuse 1.5 A --/
As long as the fuse doesn't burn, I don't see a problem. And if the fuse burns during a high current (dis-)charge, then everything is still save and we learned that this cell combination isn't "compatible" (at least not for high current).
@@z7hbhf702 I may go ahead with this experiment of adding some small cells to the large ones to add for capacity lose. It's a bit tricky and potentially dangerous. We will get there...
@@z7hbhf702 let me ad this.. I build large 18650 packs some 2800cels , if I have a weaker pack , I simply ad one, ore a few cells to balance it ( it doesnât matter because the IR wil always variĂ©tĂ© .. some packs I am running for over 8 years now and they stay perfectly in line. Maybe running of for a few milivolts a year.. easy to hand balance.. the cells that I ad isnât going to charge ore discharge slower ore faster in the same configuration because it became a part of the configuration ,, wye fuse? .. itâs not a big balloon đ whit a small one tied to it ⊠itâs the same balloon, inflated a little bigger .. that volume I added isnât going to do more ore less if it is the same material.. only the balloon in it self can do more
Andy I am yet unable to find the dc power supply your using for raspberry pi. The black unit. Please share link. Its not in your Web site.
Also one more question my mccb are tripping when I am on the hot water. I hv a 250A mccb but its not non directional. đą typing while watching your video.
Your really having fun with this project.
Yeah, it's a fun project!
Not sure what black unit you're referring to. The Pi is been connected to a 5V DC Buck converter directly from the 48V battery system...
If your breaker is rated for DC and non directional, you can still use it for loads where the current does not reverse.
@@OffGridGarageAustralia you have this dc din rail voltage meter. You removed the buck which you had sleeving and put this. Where you adjust the voltage I think it's in put voltage was 60V if I can remember from you 1year old video.
I have ordered eve 280 cells from gobel power. They are cool, both cells and gobel =) But I didn't know they produce own bms...
None of these companies produce their own BMS, neither Seplos, EEL, QSO, Jakiper nor Gobel.
Is that a Batrium copy!
If I were to make a Frankenstein battery, I would make each cell pack (ie each set of parallel connected cells) to be the same Ah, or close enough. As you want 48v, that is not an option, just a thought about how to use extras. I would imagine that each "cell" would not matter as long as the individual parallel sub-cells, add up to close to the average of each cell. If that makes sense...
We will do this at some stage and add some smaller cells to the 280s. Will be an interesting experiment.
The only thing I can think of with the button cell is for CMOS/RTC/MEMORY backup.
Yeah, it's for the RTC apparently. How do other BMS do that though?
Andy where was the Michael Jackson act mate. lol. Did you work out the math for the Aluminium bars ?
There was enough acting in here, so no Michael Jackson... probably all copyrighted anyway.
No maths for the busbars, just some off-cuts, I had lying around. Working really well.
Servus Andi! :)
auf einen der Zellen habe ich eine Abdeckung (rot) gesehen, scheint aus einem 3D-Drucker zu sein, hast du den link zur vorlage fĂŒr mich? :)
Andy when is the next video we are waiting its Saturday night đ
Not enough time, man. I wish I could make more... Hopefully tonight...
So will this BMS fit where the Seplos BMS is on the case? Maybe a little modification required....?
It will mainly fit with some mods. Testing it at the moment. Seems to be a lot better than Seplos BMS. But just wait for the final testing...
Off topic but im unaware of any chatroom or forum for you but what do you think of a Giandel inverter?
I'm not in many forums due to lack of time. Don't know anything about these inverters, sorry...
Sir: Am I correct in thinking that with a 150 amp BMS over 280 amp cells the cells will never be hard pressed?
A T Burke
Well, it depends on your load. But I have several batteries in parallel, so the current is usually very low for each bank.
@@OffGridGarageAustralia Thank you so much for the reply. My thinking was that your BMS (150 amps) will hold both inflow and outflow to just over 1/2 of the cell's maximum rate (280 amps), in fact just .54C. This should increase battery life over a situation where the cells are used at max input/output. I also have heard that (in amps) max input is more destructive than max output. Is this your opinion or experience?
A T Burke
Das Intro đ
Thank you! đ
I have a franken battery - 1x~15kw pack (mix of 280&300A) & 1x15kw pack (all 300) in parallel with 2 JK BMS.
The issue is balancing, the voltage profiles under charge are wildly different & maintaining a top balance is near impossible. I set the the balance to turn on at 2.8v!!! which really helps overall. There's just too much drift over time after a top balance to maintain all the different cells.
When you back off charging at the top some cells take off at 3.42, some quickly drop to 3.38... just all over the shop!
You need active balancing in addition to the JK.
@@FutureSystem738 JK has 2A balancer, i have a heltec spare - u think it would make a big diff? seeing 0.06v diff when it counts
Charge to 3.45V and see how the spread is. The JK could be enough once fully top balanced. The voltage will drop again to 3.35V after stopping charging, that is perfectly normal. But, yeah, you can parallel the Heltec balancer to the JK.
@@OffGridGarageAustralia already do that - pack charge to 55v = 3.4375v each
When dropping from 50A to 20A charge *some* cells drop, some dont - so voltages are all over the shop.
Pack has been balanced multiple times & a few cells seem to keep going low at both top & bottom.
@@nateb3105 The weak link with the JK BMS (and of course many others too) in a large pack (Eg: 16s) is unfortunately that it can only balance two cells simultaneously, ie: one cell thatâs high feeding into one thatâs low. Thus, if you have a significant number of high cells and a significant number of low cells, it really struggles to keep up. Although it will use its full 2A, itâs only working on two cells at any one time.
Thatâs where a good active balancer will likely do a better job.
A ompany in the UK call puredrive , am 90% sure that's the bms in their ready-made battery packsđ€
Wouldn't a jk bms be a better option, since it already have a 2a balance current capability?
From what I can tell so far JK doesn't have the current limiter or nearly all the software options available that this one does.
The JK is great for a single battery, but if you want to parallel more and get bigger setups, it's not the right choice any more. It lacks some features you probably want in such an environment (comms, safety, ...)
@17:58 OCD alarm lol.
Donât forget to sand the oxide off the aluminum buss you fabricated and a film of non metallic antioxidant. Dialectical silicone, no-ox-ID A special or synthetic marine grease on contact surfaces but not on the fastener threads. Nothing wrong with using aluminum, it just needs prep & protection.
No prep here and it works a treat. I stopped using any paste or grease and had no issues since with any of the connections.
@@OffGridGarageAustralia
Luckily for you no salty air.
Very Interesting Igor... I suspect you will be limited to the lowest cell capacity and if you don't limit the monster to that then you run the risk of the lowest cells failing - similar to badly balanced laptop batteries.
Did you run a Mitsubishi Outlander Phev? ..... You seem familiar.... đ
Like with all batteries, they are only as good as the weakest cell.

andy question did muller energy ever created the 16s jk-bms with the 5A balancer?
I think they asked JBD but need to order a sh*t ton of BMSes for them to make them custom built. I think this will not go ahead. But we have some other options these days...
Andy? Will this become the Mercedes in some never imagined way? MerceLiFePodes ? Yes? đ€?
i am confused how did you eventually get this to turn on
I haven't seen any arcs ..... is it really alive ? ;-) :-)
Enough thunder and lightning. I don't like sparks or even arcs... đ
Will this fit in a seplos case?
Yes, but the cut-outs for the LEDS and communication ports may need some adaption.
Andy are you up in QLD ?
the seplos HAS that switch
OK, thanks. That is definitely worth upgrading.

I have JK BMS in my batteries 620Ah 24 volts x2 Total 1240Ah 24 volts
Sure my batteries are fully charged I have a problem with the BMS turning off my batteries.
BMS set to 3.6 volts then turn off my inverter 230v for a while and it starts up again.
it looks like a cloud is coming to cover the sun the sun will come again there is so much current that it switches off it only happens when my batteries are fully charged what can i do about that problem
My system 1
SmartSolar MPPT 250/100 solceller 3200Watt it is set to max 28 Volt charging 80 amps in max
My system 2 Outback FM80 Stand for 27.5 volts and it stops 40 amps in max
In Alt with full power 120 Ah batteries
SĂžren
Set 27.6V for Absorption in your MPPT. That is enough to fully charge your batteries and it should not trigger your BMS.
Monitor the BMS if one cell goes over 3.65V during charging. That could indicate a balance issue.
15:20 By the time the BMS shuts off at 90â°C, it is already on fire.
Yes, I thought so too. These temp settings are not correct...
Its alive!!! Its alive muhahahha!!!
