I read one comment (unknown source) stating that Lead Acids would degrade over the years no matter how much or little you use them, simply because of the materials inside degrading (as with corosion) over time. ........ Could something like that be the case with LiFePO4 as well ?,........ that the cycles doesn't really matter that much ? ........ Any comments ?

Hello sir, I want to learn about that on which basis design the battery pack for electrical vichles

Hello Starting to thank you for all the good movies you make. Looks like you can finally get it a little cooler in the garage. See how you measure the temperature and that it doesn't go down that much. It becomes a bit inefficient with this type of cooler as it takes all the air from inside, some of the air comes back cold, the warm air that is blown out is also taken from inside, this means that you get negative pressure in the garage, which means that the warm air from outside is sucked in via the ventilation. SINCERELY Larry

HI Andy! In the bms there are two cables both going to cell no. 8. How did you set them up? Thank you

Balance cables - you could cut off the 3 mm ring lugs and install new 6mm insulated lugs...

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 ;-)

Is there a rule of thumb what current the integrated Balance should be capable of based on the battery size ? I can remember that many had taken the 2A JK BMS for the usual 14,3 kWh EVE LF280K batteries, but what about a 3,6 kWh LFP 16S battery (74 Ah) ? 16 x 74 Ah x 3,2 V = 3789 Wh or 3,8 kWh which would mean 27% of the big 14,3 kWh. And these 27% would equal with a 2A BMS just 0,54 A A 0,6 A balancer should have even more reserve, but the main question is still: How should the balancer be layed out to get the battery balanced (battery capacity) and when to get a 4A or a 2A or 1A or 0,6 A on

Oh Andy 🍺🍺

17:15 This is my personal experience with A.I chatbot, is to not generalize the question too much, give it an more accurate example, tell it that you discharged it normally, then shorten its terminals, i think the bot take into consideration of shortening a battery at an unknown remaining capacity and energy. my guts feelings is if you ask general questions, you get those standard baby-safe paper-manual text nonsense. 18:42 much much better generated answer in my opinion.

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!

you have the wrong polarity on the BMS, you have connected the negative of the BMS to the positive pole of the cell.

Sodium will be the future of home power storage

Abc avoid to buy Chinese.. but in this case we do not have solar systems..😂 a bit shitty..😂😂😂

Typical case of banana battery. Matures with the customer. 🤣 Thank you very much for your honesty. 👍👍

I bet they designed the battery box for 100amp cells.reason for build not fitting well

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.

made for 280ah cells not 304ah

People think that if the products are expensive, then they buy quality goods

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?

Yet another add to cart, but by the end of the video remove from cart! Been nothing but donkey balls lately!

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.

Mybe The 280 Ah Cells are a tiny Bit smaller. As Gobel subscribe The Box for 280 Ah Cells

Can pace bms works parallel with daly bms

You could screw up your existing GobelPower battery box to can see how the connection cables are to be used. Be happy that the balance cables has ring lugs. My 200A BMS I ordered to change my "old" 150A GobelPower BMS came with a balance cable WITHOUT ring lugs. Good that I can use the old balance cables. As I told, I ordered one and hopefully it comes with a display. The missing built up manual is really bad. Hopefully GobelPower made a download on there WebSite. The position of the Neeeey balancer is really bad. If you want to change the balancer you have to srew up the hole front....horrible. My GobelPower DIY Box I have ordered with the 200A PC200 BMS and should come with a screen so that than all my 3 GobelPower batteries are the same.

Can we have a white DIY box for JK BMS that doesn't suck?

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.

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

51 F isn’t “fizzing cold” lol. Sounds nice to me.

Hi! When you set your RCV time to 1h and RFV time to 6h. This will charge the battery twice a day. Once in the morning and once in the afternoon. Or am I missing something?? Thanks!

Years ago when I started an aborted foray into solar I bought some used CALB 100ah cells. What are the recommended cells to buy today, and from which vendor’s? Thanks!

At 16:20 ... could this box be for a smaller battery? Maybe 220 or 230 AH cells?

Thanks for these videos. I was wondering if the 40A tester in this video could also serve a a charger for initial cell top balancing, and then for 48v pack charging if needed? If not, do you have a recommendation for a 48v lifepo charger? Thanks!

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.

is the box a parallelogram? get a square and check!

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.

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

Dunkelflaute here in Eastern Australia

the W is probably for white

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.

just Macgyver it Andy ... use your 3d printer to make adapter brackets

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.

Greatings from Ukraine! Thank You very much for Your work! I have such BMS with HW v15. I updated it to version v15.17 from v15.11 based on Your instructions, but I can not find any changelogs for this firmware. Does this bug persist in v15.17? Is there any way to read what have changed between FW versions? Thank You in advance!

thanks for the duck alert!

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 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.

Thanks Andy

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.

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.
