looking for BMS brands/references in Europe

[silos]

Hello All!

Im new to DIY battery world, living in Berlin since 2018 and I dont speak german! So, there are a lot of challenges for me to go deep on this topic from here (particulary because I dont have too much money and I need a lot of information). That is why I came here to try to find some help

I watched few videos from Will's channel in youtube and I can see that the BMS system that he show on most of his videos are a system that have just one central box and wires that goes to the cells. Here is a picture of him showing these system in a few videos of him:


www.youtube.com/watch?v=im4ggvoni5M DIY 48v LiFePO4 Battery w/ $72 Bluetooth ANT BMS (low temp cut-off!)


www.youtube.com/watch?v=_ntcAZfxju4 Testing a New LiFePO4 BMS, 12v Battery Build and Aliexpress Cell Test


www.youtube.com/watch?v=zStEtH9Le-w How to Build LARGE LifePO4 Solar Batteries w/ Raw Cells and a BMS

So, in all these examples, he is using that BMC system that is 1 box and few wires.

Since I live in europe, Im trying to find who is using these systems Will is showing but I could not find anyone. Instead, I see people using another system that have a different approach.


I took this image from: https://www.wohnmobilforum.de/viewtopic,p,2160442.html#p2160442
I saw this kit in the picture being sold on: https://www.nothnagel-marine.de/pro...kl--BMS-u--Sicherheits-Trenn-Relais-250A.html (it is really expensive!!!)

But they don't specify what circuit they are using in this advertisement.

So here are my questions:

1. Do you know what brand/model of the BMS circuit they used in the yellow battery above?

2. If you are from Europe, can you tell me few cheap BMS brand/models to work with? (the ones that have temperature control)

3. I see here they have LiFePo4 and LiFeYPO4. Do you know why they use this second name instead of just LiFePo4 ?

4. Im looking for places/sites to find where to buy cheap LiFePo4 100Ah cells to build my battery from scratch. I will also need the BMS. If you have any clue on where can I find it here I appreciate that.

Since we are living under corona times, I excluded the possibility to order these materials from USA because I think it will take a long time to arrive here. So that is why im asking for references of brands/names in europe.

Sorry for any bad english.

Thank you!

Hi Silos,
battery shown in the Image have single BMS"s for one cell with OVP/UVP protection, wired in series as a Daisy chain circuit. To switch load either MOSFET's or latching relays are required. LFP Ytrium battery (Winston) have a better acceptance for low temp charging

the last one looks like the bms123 I think
this one https://shop.gwl.eu/Battery-Management/BMS123-Smart/

It is not the 123BMS, but it is of a similar kind. In Europe a lot of the Yellow Winston cells are sold from Prague, they also sell the Dutch 123BMS.
I own such a set, and it is of much better quality than the Lishen or Eve cells with Daly or JBD/overkill BMS.

But I do like the cheap stuff better, I'm not using my expensive Winston/123BMS setup at the moment but I use my Lishen Cells with a JBD 120A BMS. Much smaller size, less weight, and still good enough for my light use in my campervan.

ah
thanks for that
I did not know that there was another version lol
I hae a GWL CPM style system atm tbh as I like the wide voltage options and it also is about 200-250 in total pretty much
