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

    The secret to compression

    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.

    Pack / Cell compression Optimized By Using Springs.

    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.

    Seplos CAN BUS RS485 48v 200A 8S-16S BMS

    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...

    Last fire.. :-(

    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...

    Don’t buy fromShawn Best on AliExpress!!!

    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!

    Pack / Cell compression Optimized By Using Springs.

    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...

    My purchase of 16 cells at Alibaba - Dongguan Lightning New Energy Technology Co,

    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.

    My purchase of 16 cells at Alibaba - Dongguan Lightning New Energy Technology Co,

    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.

    My purchase of 16 cells at Alibaba - Dongguan Lightning New Energy Technology Co,

    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...

    My purchase of 16 cells at Alibaba - Dongguan Lightning New Energy Technology Co,

    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...

    My purchase of 16 cells at Alibaba - Dongguan Lightning New Energy Technology Co,

    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 purchase of 16 cells at Alibaba - Dongguan Lightning New Energy Technology Co,

    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...

    My purchase of 16 cells at Alibaba - Dongguan Lightning New Energy Technology Co,

    So, I decided to create a new topic about buying cells for alibaba. The background is as follows. I have not been very successful in ordering EVE slots in the Bassen. No one there was in a hurry to send me the ordered cells, all the deadlines for sending were over, and even more, and I decided...

    WARNING. Do not buy from Shenzhen Basen. Alex Chen.

    I think so. Judging by the behavior of BASSEN sales representatives. But this is my purely personal point of view.

    WARNING. Do not buy from Shenzhen Basen. Alex Chen.

    I also ordered from BASSEN. But after 25 days, I withdrew the payment. It looks like I did the right thing, despite the loss of Alibaba's commission and the exchange rate difference. Looks like BASSEN is sinking to the bottom... I received my refund quickly, in two days.
