Claudio, your English is perfect. I am also a non-native English speaker for 40 years and I don't think I can speak as correctly and FAST as you do. Great explanation of the features and functions of the BMS box, Thank you!👍
Very useful, great video, thanks for sharing, looking to build a system, mostly plug and play , so the info about this BMS helps a lot, can we see a video with this BMS working in a real life scenario? BTW don't apologize for your english, its great!
Hi, how many of these modules can be connected to one BMS in a 48V configuration (Victron Quattro 15kva) and if more are needed can these BMS units be daisy chained ? Am currently planning 2 systems one with 30kwh and another with 60-100kwh. Also, due to the 6S config of Tesla 444 modules there will be limitations in the full range of voltages that Victron can use out of a Tesla pack. (Quattro / Multiplus cannot restart once battery module voltage drops below 20.8V, and it then reaches shutdown voltage of around 19V , (it will need to be brought back up manually to 20.8V via generator / grid etc before the Victron can be restarted manually which is not possible if owner is not present, leading to battery damage. Can this BMS overcome this issue somehow ? Thanks.
Hi, I've just subscribed, excellent video thank you! I had a 6kw Fronius gen24 hybrid inverter with 6kw of panels installed last Feb. All is working well but now I have come to buy batteries I find I am limited to the BYD system which is about 1800euro for 20KW !! I want to change my inverter but can't use a Victron as they unfortunately don't produce a 6kw (or bigger) hybrid single phase. I am seriously considering a Solis RHI-6K-48ES-5G which has a built in BMS that communicates via CAN BUS. I am buying 4x Tesla 6.3kw 22.8v modules 2s2p configuration to give the correct voltage. Finally the question... Will the Victron BMS in your video work with the Solis inverter? Sorry its such a long explanation. Many thanks
Aha! Ive just noticed your comment at the top saying the BMS works with any 48v system. I'm assuming that if it is all CANBUS then there will be no issues? Thanks again.
So, you want to make 15 kWh @ 24V, correct? You can connect them in parallel and BMS cable will be the same. If you use BMS from BPATH you can select into settings if you are in series or in parallel. I will make a video for this situation, thank for ideea :)
What cooling system would you use to keep the batteries either cool or warm, operating them within an appropriate operating temperature? In my case, I only need to keep them cool, since I'll be operating them in warm temps.
@@emceh Has own settings options direct on the LCD, some more features like cooling and heating options. No need a PC to set and also is almost plug & play. So is better in my opinion. :)
I want to start this project. I need a home battery to charge at night and discharge during the day into my house. No solar. The BMS is the only part that was missing in the puzzle. I just checked and it’s out of stock. Secondly it’s too expensive. Because these days batteries like sunsynk come at a very cheap price. Also, will you be able to provide a full schematic diagram of your Tesla power wall built ?
@@CaptainProton1 Can you suggest some good options? The only reason I wanted to do Tesla batteries was that it is really cheap as compared to a new home battery pack. Can you suggest any car using lithium iron phosphate batteries, which I can find secondhand ? I live in the UK.
Hello, i see your Video Today 👍 … i want use 4 Tesla battery modules for a 24v System. How many bms i need? 4? … i want use with an victron Multi plus … do you make also a plan for korrekt Kabel Position?
We plan to purchase this unit, I use all victron inverters (Quattro 48/5000), does Bpath BMS control (turn off) victron inverter and mppt solar chargers when batteries are full? (Not open contactor, turns off charge on victron Quattro?) 3) are bpath using stock Tesla control board on each battery? 4)Where does the startup power come from for Bpath BMS if the contactor is open to power the interface and tell the error or do setup? 5)how many amps can boath unit carry, I saw gigavac 400, but copper is looking thin, and wire holes are small for 2/0 cable to batteries? 6) do you have some fuse or some protection in case of emergency shutdown not to blow Bpath BMS computer board? For example: If the batteries are charging and there is a overload or bad cell detectected, and the gigavac contactor opens the dump loads or current rush that went to charge the batteries now will blow your board? Or you have some fuse? 7) do you control the victron charging voltage (plus on off) or What is maximum voltage (charging curve) you suggest to charge paired (2) modules? 50? 8) what is the maximum variation you suggest, or BMS allows, between cells, .30? 9) to verify if the precharge resistor is built in
Hi Eddie, we have in stock in our store in Romania - 1,669.34 USD. We can also ship WW, but shipping cost is extra, around 150 USD. pvshop.ro/bms-pentru-acumulatorimodule-tesla-model-s-plug-play-bpath-energy
Also das gefällt mir, wenn ich richtig verstanden hab dann kann ich damit jede meiner 10 Tesla Akku packs Steuern und brauch keine extra Balancer und bms Systeme?!? Wie werden die einzeln angesteuert? Wo kann man sowas kaufen? Danke Gruß Franz
Hallo Franz, In jedem Tesla Model S/X-Modul ist ein Balancer installiert. Dieses BMS fungiert als Master und stellt eine Verbindung zu diesem Slave-BMS her, kann die Temperatur vom Modul ablesen und auch die Zelle ausgleichen. Wir haben eines auf Lager, der Preis liegt bei etwa 1500 EUR, inklusive Versand.
@@thecstechvideos hört sich perfekt an, 🤗 kann ich damit 10 Module ansteuern? Das dann 48v im System gibt? Und ist das dann kompatibel mit dem bestehenden System? Möchte das als Erweiterung verwenden. Aktuell sind 3x Victron multiplus verbaut, mit cerbo Gx und Touch 50, da dran hängen 3x 7,5kwh Akkus aus vw Zellen. Wenn ich den Controller mit den Tesla Akkus dazu hängen kann, spricht nix dagegen den Controller zu kaufen. 1500€ ist zwar viel Geld aber basteln kostet sich was. Vielleicht kann jemand Infos geben ob das dann zusammen funktioniert oder sich die Akkus stören oder die Victron keine Unterschiedlichen Systeme nimmt. Danke
with all due respect, you should include the follow-up video with the main video as you have a terrible track record of not posting your follow-up videos... ever. I have watched three of your videos now promising follow ups and there is nothing... after a year or more.
Really good video, thanks for making it in English.

Hi. Can you make another video showing how it works, how it is connected to working system. Also what other inverters are supported.
Looks mega. Where would you recommend the “Tesla Powerwall like” casing could be purchased?
Was custom made by me :)
My friend, what the unit name manufacture thank you

I have 4 tesla s modules. I want to put 3 of them in paralell. Is that that the same procedure as for in series? Thanks, great video!

Until 33-35 Celsius is ok to work without cooling.
What do you think about this BMS?
FOR model 3 battery ar any bms control ?
Not yet
Will this BMS work with other inverters or just Victron? We have MPP Solar.
Only Victron since has CAN Bus communication.
Ok sorry found the link but out of stock, how many batteries will this controller do?
We still have one in stock. PM me on contact@cstech.ro
This looks great! Too bad I bought a SIMP BMS already. I don't think the SIMP can control a heating/cooling system.
This one works great, I will make a video that test that :)
Looks like it's based on simp BMS so adding some features still possible with your board
@@emceh Has own settings options direct on the LCD, some more features like cooling and heating options. No need a PC to set and also is almost plug & play. So is better in my opinion. :)

Use Lifepo4 not li-ion if it's going into your home. Not worth the fire risk if your bms messes up.
Correct!

You need only 1 BMS

I use all victron inverters (Quattro 48/5000), does Bpath BMS control (turn off) victron inverter and mppt solar chargers when batteries are full? (Not open contactor, turns off charge on victron Quattro?)

6) do you have some fuse or some protection in case of emergency shutdown not to blow Bpath BMS computer board?

I have 2 units and a mpptsolar hybrid. Do I need a BMS? There is a BMS on the battery
Any li-ion battery need to have BMS and balancer.
Hi, please provide me the link for this BMS unit. Thanks

So this BMS costs more than the 10KWH of tesla cells on the table next to it. Does anyone else think that's an insane price?
Without BMS Tesla battery pack are useless and unsafe. I will make next week another video whit another BMS for Tesla and WV
Link to buy and cost?
PM me and I'll give details.
