Good afternoon, dear friends! It's time for me to sort out my BMS and backup power system. Now I have two bms seplos, versions 10c and 10e. At first I had no way to coordinate my victron multiplus 2 and seplos bms version 10c. There was a lack of time and understanding of how they should work...

I have placed two orders with Adam. The first time there were difficulties with delivery, I received my order only on the second attempt. The second time I arranged the delivery myself through a forwarder I know, and everything went fine. The communication with Adam was quite satisfactory to me...

Absolutely correct. I now have these two versions in working order, I was able to fix the 10C version and bought the new 10E version. So I can compare.

Well, it's probably not quite right to assume that the wood is not suitable. I have 21 mm thick plywood side plates. And I think it's very suitable :) But OSB 12 mm, of course, is clearly not suitable for this purpose. And I have 5 studs per package - two on one side of the package, two on the...

Well, that's a shame, isn't it? One awkward move and the board could be thrown in the trash. Your way to Seplos for a new Model 10E board.

Battery Monitor 2.1.9 User Manual for BMS Seplos

User manual for the new version of BMS Seplos 10E

I will answer my own questions :) Alan from after-sales support sent me the answers to my questions. 1. the stubs to the battery cells are interchangeable, which is not surprising. 2. The LCD panel will also fit the old BMS version 10C. BT is built into the new version of the panel, which is...

Good day, dear forum members! I, too, was plagued by the problem of Diode D4. It took me a whole month to find a replacement for this diode and replace it. I also ordered another new BMS from Seplos at the same time. I received it yesterday too. I compared it visually - they are different boards...

I realized my mistake. Fixed it. Google so insistently translates the text every time the page refreshes.

A couple of bottles is a lot for me. One at the most :) And what did this esteemed forum member want to say? I still don't get it...

more than a year since I last posted. The cells I bought from Haley are working in the best way possible. No self-discharge is out of the question. They hold the voltage well, the kind of power source one can only dream of for those who do not yet have one. The BMS SEPLOS with its well-known...

I read the thread. I have something to say too. My BMS is out of commission too. It happens. Although the problem with the d4 diode is clearly a manufacturing problem. At least look at their diode replacement guide. I've talked to both Alan and Adam numerous times. Normal guys. Alan is so quick...

I have not yet been able to find the right part in my city. It's a long delivery from China. Ordered, parts will arrive in December. BMS is made December 2020, I received it in July 2021, for various reasons I was able to assemble the system only in May 2022. Accordingly, the BMS ran for 5...

Well, I had a bad problem with the diode d4. My bms doesn't turn on anymore and doesn't show any signs of life. With the instruction, kindly provided by the seplos engineer, I took measurements and found out that the diode is punctured and needs to be replaced. Many users have suffered from this...

It is necessary to download the file to your computer, unzip it with any archiver, and then run the executable file .exe

Then you'd better buy a 5-volt unit, something like this https://aliexpress.ru/item/33058889593.html

My personal opinion is that I don't think this method is effective. It looks like a desire to do something, but the effectiveness of such an action tends to zero. Especially for longer periods of time, a year/two/three... Foam cannot provide stability.

I solved this issue a long time ago. My threaded studs are insulated with a plastic tube of the right size. It is transparent, so it is not very visible in the photo. Read carefully the text, where I describe my construction.

I also received my BMS Seplos 200A 16S today. Unfortunately, I don't have free time right now to run my VIKTRON, BMS and Venus GX, as well as the adapters to connect these devices to the computer. These are the MK3-USB interface and usb 485 adapter connect BMS battery management system and...

Dear fellow enthusiasts! I periodically read the forum. And I have noticed several disturbing cases about combustion and/or thermal acceleration of large-capacity cells. My experience leads me to the conclusion that many of us ignore the need to carefully insulate and protect the exposed live...

Such a supplier should be posted on the board of shame, in very large letters, so that he could not deceive anyone else here on this forum! Do we have such a topic? What a disgrace!

Forget that crook... Don't waste your precious time on him.

I bought a device like this. You can do everything neatly and reliably with it.

Truly we all live in one big world, and it is one! :)

Итак, позвольте мне попытаться описать мою компрессионную сборку. Я изучал опыт предыдущих товарищей на этом форуме. Я изучил таблицы данных и всю информацию, доступную здесь и на других ресурсах. И решил создать свой узел. Поскольку у меня батарея 16S, я считаю, что расположение с пятью шипами...

I'll try to show you here what compression spring tensioning device I have constructed. The photo is a test version. It is assembled for testing. And the test was successful, I am satisfied.

Who knows? You have to charge it, then wait a month, then measure the capacity. I measured it an hour after charging. So self-discharge has nothing to do with it.

Cell #13 had a bad surprise - its capacity was 296.1 Ah. Sad, sad, sad. Since the battery is evaluated by the lowest cell capacity, I will not get a high capacity, although there are 317 Ah cells. Too bad. I'll keep running tests. I checked cell 13 twice, in order to avoid mistakes. I only...

The test of the second cell from my batch is complete. 317.7 Ah. I can only say one thing - I am satisfied. Will be testing two or three more cells to choose from later. I don't have the patience for all 16 :) One test goes for 15-16 hours. The second test I limited the voltage below to 2.5...

I was buying. And the first capacity test passed. Now I'm testing the next cell. https://diysolarforum.com/threads/my-purchase-of-16-cells-at-alibaba-dongguan-lightning-new-energy-technology-co.23066/#post-273523 How long it all takes...

Well, I finished the full capacity test of cell number 3. Discharging to 2.8 volts (95% SOC) showed that the cell has a capacity of 294.5 Ah. If converted to 100%, the capacity is exactly 310 Ah. Strange coincidence, isn't it? Like a drugstore. I don't believe it. Here's a screen shot. I will...

My dear, it’s time to understand that the cells are new, and even CATL, you will not buy at such a price. And don't buy it at all. Cells from disassembly, and everyone who wanted to know this already knows. Everything is worth the money. Read more and more often the forum, and a lot will open...
