I have yet to see anyone else take the precautions you have. Being an electrician myself, I know how little the amperage needs to be to kill any human (one milliampere = one millionth of an ampere). So to see your intelligent manner in preparing these modules is refreshing as I have seen so many people who know just enough about electricity to be dangerously negligent, bordering on disrespect of the potential power with which they handle while taking these batteries apart. They have no clue as to the very real dangers of the amperage they’re handling. Perhaps if they had the opportunity to see the consequences of a single mistake, they would take the necessary precautions you have in this video. So thank you for taking the time to show respect for this power we call electricity = but I look at as the Hand of God Almighty as it has the “power” to take life away and to give it back, in an instant. With regard to a BMS, you might check out jag.35 as this DIY company, has fabricated many BMS in the systems he has offered. Just FYI.
Yes, those batteries are not to play with.
I decided to go with Orion bms system and I am very pleased with it.
Thank you so much for your comment and information😃🙏
I'm considering doing a similar setup with Tesla batteries. I had a minor concern when on the fitness mat over the grass. I was thinking some plywood sections over the grass would add another level of safety. I was also thinking something like a plastic carpet runner or large rubber mats over the modules would make things safer. if a high voltage accident were to happen its possible to accidently fall on top of the modules.
one milliampere is actually one thousannths of an ampere not a millionth. A millionth would be a micro ampere.
I was thinking the same thing especially when he said he's an electrician 😂@@marviwilson1853
That's good progress just getting it functioning is good. Must make sure cells are balancing though in order to avoid boom boom and ideally have a remote shutoff.
That’s already been taken care of.
Ended up with Orion bms and home assistance controlling the inverter
Thank you so much for your comment 😊
Ojojoj, så nice! Grymt att lyckas köpa batterier på en skrot!
Den här typen av lösning och storlek på batteri har man ju drömt om hela tiden! 😀👍
Ja denna storlek är helt ok, även om jag endast cyklar det på lite drygt 30kWh för att vara på den säkra sidan.😊
@@flyingtools, lyxigt att bara köra på halvfart och ändå kunna använda 30kWh 😀
Vore guld att kunna utnyttja bilens BMS, man kan ju hoppas att någon lyckas haxa systemet så att det tror att det sitter i en bil.
@@Grejarlite det står verkligen övers på önskelistan 😅
@@Grejarlite Har ni kollat in kanalen "Dala's EV Repair"? Han reverse engineerade Leafs batteri & Fronius inverter just för sådant här. Tror hans program stöder också Teslas batteri, och Huawei inverter på kommande. Antar att programmet kan utökas precis som man vill, bara man luskar ut batteriets och inverterns protokoll.
Thumbs up 👍🏻, great work!
Regarding your battery cycling:
As far as I know, does the balancer only kicks in at max voltage and starts burning energy of peaking cells. In addition it would shut off the whole pack if a battery reaches a critical over or under charge, for safety.
But I agree if you stick to the very limited voltage range you did your cycling with, it is unlikely to exceed critical voltage rates of a cell even without a balancer, at least for quite a while.
For this growatt invertors have "Battery equalized interval" it could be configured to charge to full few times a year and to be kept at that voltage for few hours.
Respect for your work and thank you for the interesting video.
You don't need insulating earth matts when the battery module has no 'reference to earth'... as long as you don't touch the negative terminal with one hand and the positive with the other,.. you will be fine,.. the old adage of keeping one hand in your pocket,.. has more relevance than you might think...
You are absolutely right about that. But better to be a little to safe when you do stuff for the first time😅
But yes, that’s completely unnecessary.
Thanks for your comment 👍🏻
However, it does worth it to take some extra measures to avoid accidents.
Thank you for sharing. Very intresting project.
Thanks, so glad that you liked it ☺️🙏
Nice to see something witch is familiar to me. We produce into this all te black boxes. Show me the pictures of their laser engraved covers to check them. :-)
Haha, cool! I se if I can tack a picture 😃
I really like how thin is your wire to the inverter thanks to the high voltage of the battery compared to the the low voltage systems. I wonder though, why there is no water terminals for active cooling. Is it the same system as Nissan leaf?
Hi, the water channels are at the bottom of the battery box. So the whole floor of this battery acts as a cooling plate for the battery modules and the modules are sitting in cooling paste for good heat transfer. You’re not the first one who asking me this so maybe will do a video about just how the cooling system works. Thank you so much for your comment.😊
In Germany for HV3 (Working on not disconnected HV Voltage) - we dont need Leather gloves - only the usual HV Gloves but with a check if they are ok ...
Oh, interesting. Those gloves has dual protection, voltage and
arch protection ⚡️ if something goes really bad.
Thank you for your comment and information ☺️👍🏻
It's fantastic and good that we can buy these packs at the scrapyard.
- What chemistry is in this EV-kind of battery, is it the thermal unstable old-fashioned Li-ion-mix-type, or is it based on the stable (from a thermal run-way condition) LiFePo4? Cheers.
In cars they use li-ion, which is as you say much more unstable. So I hear highly recommend you to have it on the outside of your house. Thank you for your comment.
@@flyingtools I think there are teslas (especially in china) that use LiFePo4, too.
What kind of thermal management systems are there with the VW ID3 pack? It looks like there is a cooling plate, but how do they heat the battery for cold weather thermal management? Thank you!
Hi. The bottom plate of the battery is heated and cooled by liquid.
Thanks for your question😊
Hi, thank you for your very interesting video. I almost jumped on the seat when I saw my very same inverter which I have connected to a single Triple Power Battery. I'd like to upgrade to a system like yours but, unfortunately, you skipped the connection of the battery to the inverter. Is it as simple as connecting the two connectors that came from the battery? Anyway what do you think about connecting the battery in parallel with the solar panels?
Hi, and thank you, I think that’s a bad idea to connect the battery to the solar panels input without having some kind of controller between it, so you can regulate the input and output power.
Hva måtte du betale for et sånt batteri hos huggeren? Blir det mye billigere per kwh sammenlignet med å kjøpe lifepo4 celler fra Kina? (Tror de ligger på rundt 1500-2000kr/kwh inkludert frakt)...
Hej, ursäkta sent svar. 1290 sek/kwh inkl moms. Då är ju detta ”färdigbyggt” batteri med möjlighet för både värmning och kylning av cellerna samt att kvaliteten/matchningen av cellerna är nog svårslaget i förhållande till pris.
Sjukt.👍💡🔌
Hi, Thanks a lot for your videos! I bought a Skoda MEB battery and now need to take it apart and test it, but I don't have the PPE gear I need yet. Where did you find your arc flash helmet and gloves and which class do you need to work on an id3 62kWh batterry? I am struggling to find that either online or somewhere here close to Stockholm. Most places which have it require you to be a company with an OrgNr..Thanks for any tips!
Hi, glad you like them. I have ordered them from vag. But as you say, you need to have a orgnr. See if you have a friend who works for Vw/Audi. HVE is the class you need to have to work with those batteries.
Good luck with your project!
Thanks for your reply! What i meant by class was the arc flash class 1 to 4 rating for the protective gear. I am wondering if class 1 is enough or if i need class 2. Any thoughts? Also i want to use this for an ev conversion and reconfigure to 2S 88v with either 4 or 5 sets in parallel. I am hoping to reuse the meb slave bms-es with a simp master bms. Any experience/thoughts on such a configuration?
@@benjamindewilde-wj7zz ok.
Class 2 is the and clothing.
I use Orion 2 in my battery and are very satisfied with that one. Simps bms are to much “home made” stuff if you ask me, and still no balancing of the cells, at least when I checked the last time.
Orion is probably the best bms for reteofitted ev cars. It can controll chargers etc.
Super, thanks a lot for the advice!
@@benjamindewilde-wj7zz your welcome.
Good luck with your project 👍🏻
Wow. That Thing is massive
Yes it is, but still very simple to work with.
and really new.

But still, ...
Hey..please share how u made the solax work with other battery since i see they only support solax battery and i want to get a 15kw hybrid d version to make use of another high voltage battery like u did
It’s on its way, promise to be careful if you do so.
@@flyingtools i will buy one ...but dont know which car battery to look for in the wrecked selection..i need around 20kwh max as battery but dont want to spend fortune on tripple power from solax
Hello from norway! Hypothetically, could you buy a wrecked car, and run cables to it like you did and use the regular smart chargers to charge it with, and a Solax inverter to drain it when needed? Then the inbuilt bms and cooling/heating should work as intended, right? I’m thinking one could disassemble just about everything but the essentials, and keep it stored in a shed or something.
Hi, probably not. It will sense that the battery will be drained for no reason and I guess that it will grow some error codes and eventually open the main relay.
Hello, do you have any procedures on opening up a meb battery pack? im about to open up one i bought but im hesitant on what buses etc to disconnect first? is there some kind of workshop manual?
Hi!
No, if it’s out from the car there is not anything more you can do.
Make sure you have protection clothes and do an isolation test after you open it.
I assume that you have the right knowledge to do that. Fist remove the busbar between master bms and Hv+ and then divide the voltage at the “bridge”.
Then keep on dividing until you are at module voltage.
Be careful it’s dangerous, take help from a certified person from vw if you feel unsure.
Good luck with your project 😊
@@flyingtools thanks i will prepare my knowledge first before doing anything I have most of the HV protection incl the tools. the bridge is at the opposite side of the battery pack right? also i really enjoy your videos keep them coming
What inverter model are you using exactly? Can you programm the battery max. charge, and discharge voltage by yourself?
I have more info about the setup in this video:
ruclips.net/video/VW4UjZP3jhc/видео.html
Do you npt need to use the BMS system in the pack to get them working with the invertor to prevent overheating etc?
I later installed a bms to it.
Here’s a link to the video:

Need to see how you interfaced the car battery to the inverter.
I have videos about that to.
Thanks for your comment😊
Maybe I missed the point, but how heavy is the whole frame incl. the batteries? And how much did you paid for it? Thanks in advance great channel keep up the good work.
Hi!
396kg
You can find them on junkyards for around 8000euro.
Thank you😊
@@flyingtools Thank you and Happy Easter.
@@flyingtoolsWow, that's an expensive junk.
@@flyingtools I really don't think that's good value for money, you can buy brand new Renogy 12V batteries for the same cost per KWH (£300) if you spend 8k euros and they're a lot easier and safer. Considering the cost of recycling they should be a fraction of that price, especially for the ones with reduced capacity.
@@flyingtools well the price per kwh doesn't seem bad at all 🤔
Thanks for spreading the knowledge!
Would you mind sharing contacts of the junk yard you are using to buy batteries?
And thank you for watching 😊
They don’t want me to share that info. The most of the battery’s I buy in Norway, but this one is from Sweden.
Why would they not want it? They need to sell their stuff.
@@lekago i didn’t ask them that. I only respected it. I guess that if something bad is happening, they don’t want to have their name on it. And they don’t have any problem to sell those batteries anyway.
:D
Nice. I like it. So you could probably monitor the cells via can commands?
I'm very surprised you didn't put a fuse between your connections to the battery. Brave.
When/if you open it up again.. I hope you do drain one cell to see if the bms is going to balance it. and likewise.. charge a single cell above .04
Yes, I hope so, and I will also se if a cell is balancing, so hopefully no need to open it up just to check that, I will definitely have a main fuse before the connections in the near future, this is just a temporary setup.Thanks for your concern👍🏻
I service these batteries at work. I like working on them.
Same here👍🏻 And as safe as a high voltage battery can be if you compare it to some other car manufacturers. Thank you so much for your comment.😊
Do you know what the balancing fuse inside the battery is rated at? I keep hearing different values and get more and more confused for every time I read a new rating :)
Very nice video 🙂 Can you tell me where the NPT sensor is connected and what its value is. Unfortunately I can't find anything about it on the internet 😞
Hi and thank you so much 😊
I plan to measuring that up and make a short info video about that and also how it is connected. I think it will posted in the next week.
@@flyingtools Yes, I still need the sensor. then I can also put my solax into Run.
@@RichardSteigmann I will help you with that, when we know the ohm at a given temp you probably can run it with just a resistor, as a test at least.
@@flyingtools Yes, thank you. That would certainly help.But I still need the info, which plugs this is and which pins.That would be really great. 👍👍
@@RichardSteigmann I will let you know all of that 😉
Hi, did you manage to get the ORION BMS to work with this Solax inverter? I am just about to spend a lot of money on Solax inverter, Orion, Battery from E-gold ,.etc and dont want to find out later that something is not compatible. Do the Orion and the SOlax communicate nicely through the CAN? Have a you had any issues? Thanks.
Hi.
No, it should be possible but I use home assistant instead between my battery and inverter. Inverter is still in lead-acid mode.
The battery is protected stand alone by the Orion bms.
would you share what home assistant do you use?
Hur har du lyckats köpa begagnat ID.3 batteri, var köpte du ditt?
Hej!
Jag köpte dem i Norge.
hello , the can communication of WV is compatible with solax high voltage?
Hi, No its not.
Taking safety to all new level. Rich rebuilds would just rip it open with bare hands 😅
Better to be safe than sorry. 😉
What kind of inverter are you using with the high voltage battery?? Link for the inverter being used please.
Solax x3 g4 runs on a 400v diy lithium battery.

what is the inverter model. or do u know any other models as well which supports 400v battaries?
Solax x3g4
i had a problem with the id 6 " high-volt battery " risk of fire . And when i diagnosis the vehicle i found A fault on Battery control Module it says "pre warning over temprature" i need you help?
Hi, that doesn’t sound good at all. Sadly I cannot help you with that.
I think it is possible to use build in BMS with SimpBMS.
Hi and thank you for your comment. Yes, I try to find more information about them.
Var i Sverige finns systemet? Hade varit väldigt kul med ett "öppet hus"
Hej. Ja det hade säkert varit jättetrevligt men vi får nöja oss med det som finns här på YT
Tack för din kommentar 😊
Cool
Spännande. Behöver du ingen kommunikation mellan batteri och inverter? Vilka spänningsnivåer klarar invertern att hantera?
Nej, detta är en av få inverterar som klarar det. Men det är otroligt viktigt att ställa in invertern rätt, annars är man rätt rökt, bokstavligen. Menyn är även låst med en kod som installatören har.
Den kan hantera mellan 200-600v
@@flyingtools Grymt! Letar lite efter någon sån här lösning själv där man inte är låst till något specifikt batteri. Är själv elektriker.
Finns det någon möjlighet att få prata med dig och få lite tipps och ideer runt detta?
Mvh Mathias
HI i buy golf 7 pack battery 8.7kwh and i want to do as you , what 's name of your inverter? in your video you connected directly battery on inverter ?? without modification of accus??
thank you
Hi!
I use a solax X3G4 15kw hybrid inverter, you will find more info on my channel.
Yes it’s connected directly without any bms, but that’s is going to change😉
Yes👍🔋 ⚡🔌💡
Thank you Igor😊
Cool🎉
Nice. Is a surprise. I was expecting to see e-tron battery :)). Will you rearrange the old battery for the same voltage?
Tanks. The e-tron battery was only interesting for its 3s module configuration but now when I can have a wide voltage range this battery is so simple to work with if I want to remove the modules from the battery tray and install it in my house.
I sold the 48v battery so I could pay for this battery.
@@flyingtools I was expecting e-tron battery at full voltage.
Hello. I want to use one module 48 v 5,3KWt from an VW ID 4 battery with a hybrid inverter, could you suggest a bms board for this battery?
Hi. I use daly smart BMS for my 12s id3 battery module. It’s very important that you use a bms with a maximum balance current at only 100mA. There are small fuses in the balance leads inside the module that’s not are possible to change.
I’m not sure about your module but probably the same.
@@flyingtools Hi. I am thinking about that BMS so I read a lot about it. Do you think Daly 12s 300A will be good for this battery? Thanks 👍
@@ivansofilkanych1622 yes that will be great. I have used 250A with my earlier battery’s with good results. Just make sure that you have the right cell numbers and you should be fine. Good luck🔋😊
Tur att jag följt dig en tid nu så jag vet att du har bra koll, annars hade jag nog inte vågat titta!!! 🤣 Ska bli roligt att se vad du hittar för lösning på detta! Själv har jag beställt 12 st dubellsidiga solpaneler som jag ska bygga en solföljare till. Har du något tips på styrenhet för solföljaren? Mvh /Peter
Tjena, spännande! Jag har testat några trackers från eBay men varit ganska missnöjd tyvärr. Har precis köpt ett par programmerbara timers som jag ska modifiera lite. Då följer de klockan istället för solen. Hittar du en färdig sådan lösning för en vettig peng så satsa på det.
Aha, de jag kikat på är ljustyrda, dvs en ljussensor känner av var det är mest ljus och flyttar åt det hållet som "max ljus finns" de kostar runt 2000 kr
I want one of those batteries. How much did it cost?. But I would have broken down and removed each of the 9 44V modules to make it more manageable, else you've got this really big battery you can't easily move.
That’s why I ended up with building a trailer to it and install it in a insulated box.
And who know, I maybe will use it as a range extender to my EV car 😅
Yep, I was curious of the cost too. Teoretically 6 times a powerwall, but not new. On the other hand, I see chinese competition pushing price to a tenth, maybe a fifth with transport and taxes.. new....
So I guess that this one may be somewhere from 5 to 15k depending on local demand of this typo of stuff.
Hi this inverter works with 400V ? 😮 Not 48V can you tell me about inverter model?
Hi!
You will find more info in this video, and there are even more videos about this inverter on my channel l

Hello…….your name?
found your video and it is very interesting that the solax works with the battery. you said you can't share the firmware but what is the name/number of the firmware?. I also use batteries from the id3 but in a 48V system, I built the BMS myself and I use the LTC6803-4 device. I didn't see any protection in your videos, 400v from the battery is no fun and what surprises me a little is the battery input from the Solax is an MC4.... 15000W at 400V is 37.5A 🤔I will buy the same Solax for the next project but with a battery from a BMW i3, this BMS can work with the SimpBMS.
can you please tell me the firmware name.. thanks Thomas
Hi. How do you make Simp bms to work with those mudules in series? I have a lot of comments about simps bms with those modules but can not find any info about how its done or even if it’s done in series.
It doesn’t even seems to work to 100% with only one module yet. I have ordered a bms to my battery and will make a video about that later. Btw, it’s not mc4 connectors, they are bigger but looks almost the same. 30 amps is the max current to this unit so the kw depends on your battery voltage. I good thing to know before you start to plan you battery.
In your case 10,8kw with an i3 battery at full load. The firmware are probably country related with a lot of specific safety regulations so you have to take that with your installer.
Thanks for your comment 😊
hi on each battery of bmw i3 is a BMS, simpBMS is a teensy controller, the communication is canbus, the battery has 12S ( 8 Batterys in Serie ) , how can i send you a picture ?
That it will work with BMWs modules I already know, but with vw modules/balance ecu they still not able to start balancing, I think they can se the temp as it is right now. But anyway, I have already ordered another type of bms so the simps bms are not interesting for me the moment.
Thanks anyway😊
@@flyingtools Hi,I don't know your new BMS but I'm careful, every cell has a fuse inside.
Which model Solax do you have?
Hello, it’s an X3 g4 hybrid 15kw
It’s possible to buy used car batteries? I will use them as power storage at home 🏡
Yes, that’s exactly what I do here.
What inverter are you using?
Hi. Solax X3 G4.
I'm just here for the High Voltage Fashion tips, lol
I’m so glad that you are here☺️
Can you share cell voltage cable diagram?

Yes, via a microcomputer and home assistance. Thanks for your question 😊
What was the prise for the battery ?
Sorry for my late reply
1290 sek/kWh Inc tax.
how can inverter work with battery of that high voltage ? every hybrid inverter works with 48 volt batteries so i wonder what is what i dont understand here ? how are you able to connect 400 volt battery to 48 volt inverter ?
Hi.
This inverter can take up to 600v.
And it can also work with lead acid batteries, that’s the trick here.
So I have an Hv stand alone Orion BMS
And it works just perfect.
I have a lot of more videos that probably will give you the answer if you want to see/learn more.
Thanks for your question.😃
@@flyingtools oh perfect that is great thank you i will have a look :) is there any way to know how many cycles batteries have left untill they die completly ? :) your video is amazing by the way about id3 battery
@@triplextriplexxx8225 oh, thank you so much ☺️. I think it’s possible if the battery are checked when it still is in the car. As long as the cells are well balanced, I think that those batteries will hold for a really long time, especially for solar storage where the charge and discharge current are so low.
@@flyingtools i am preparimg planing my solar system thank you for your tips. Did you ground your solar system ? Against lightning strikes , do you have lightning conductor installed i suppose you have
You can use SimpBMS and have it talk to all the can bus slave board, so it replaces the "motherboard" of the battery.
I am not sure at this point if they can give balancing commands, SimpBMS can do that for Tesla or Mitsubishi boards, but earlier balancing wasn't working yet for VW modules.
Still, you can connect and see the status of all battery modules, cell voltages and temperatures, and then open or close a relay/contacter, which is already present in the battery.
Typically there is also a precharge available, but it appears that you don't need it because the Solax has a precharge procedure?
I can not find any info if they will work with modules in series. My plan is to go with Orion BMS instead. But thank you for good information👌🏻
@@flyingtools SimpBMS allows you to specify how much modules you have in series (9 in your case) and how much in parallel (1 in your case)
Here it is reported it now works with the ID3 modules
@@roland9367 that sounds so interesting!
But if the balancing not working yet I think I have to wait.
But where can I find mor info about that?
@@flyingtools Just search for SimpBMS. It sounded like they got balancing working but I didn't read everything.
Typically you almost don't need any balancing in application like yours, at least you want the failsafe to intervene.
@@roland9367 yes you are right about that regarding the balance, it’s more a nice thing to have if you can choose that when you plan to buy an BMS. However, I will give it a closer look. Thanks👍🏻

@@flyingtools lol i thought you might have been a little more professional. you don’t even know what i have to offer never mind my friend, have a great day.
Too bad the voltage of the subcells is only 44 volts and not 48/52 volts.
Yes I totally agree! Luckily victron multiples inverters can handle that voltage span just fine.
looks like you're diffusing a land mine..
Haha, well, that was how i felt to.😅
Great video, just wanted to say that i ran across another video from Dala's EV Repair where he is using a leaf battery straight from the stock connections. unfortunately, the batteries supported dont include the ID3 battery but maybe in the future. Here is the link to the video
ruclips.net/video/XHZWGLzT7gg/видео.htmlsi=Cb6Jeky3oMDC6axj
Hi and thank you. I have known about this video sense the day it came out. But after some hours of work I now have my battery running perfectly on Orion bms instead.
Great project BUT - my manager's ID.3 just went up in smoke last week. It was parked next to her house, not charging, had not been driven recently, the battery just started smoldering. The fire department came with a big truck with an open container in the back. They put the car in it, drove it to the fire station, put the container on the ground and filled it to the top with water, completely submerging the car.. The car should be taken out today or tomorrow and investigated. It is, of course, a total loss.
Google "elektrische auto broek op waterland" and click News, and there you can see the car being put in the truck. (Dutch news items)
Soooooooo..... I would be careful putting an EV battery in your house. There are safer battery chemistries around.
I would never put any type of battery in my house😅 here’s a video when I finished this project.
